How can I redirect the user from one page to another using jQuery or pure JavaScript?
One does not simply redirect using jQuery
jQuery is not necessary, and window.location.replace(...) will best simulate an HTTP redirect.
window.location.replace(...) is better than using window.location.href, because replace() does not keep the originating page in the session history, meaning the user won't get stuck in a never-ending back-button fiasco.
If you want to simulate someone clicking on a link, use
location.href
If you want to simulate an HTTP redirect, use location.replace
For example:
// similar behavior as an HTTP redirect
window.location.replace("http://stackoverflow.com");
// similar behavior as clicking on a link
window.location.href = "http://stackoverflow.com";
WARNING: This answer has merely been provided as a possible solution; it is obviously not the best solution, as it requires jQuery. Instead, prefer the pure JavaScript solution.
$(location).prop('href', 'http://stackoverflow.com')
Standard "vanilla" JavaScript way to redirect a page
window.location.href = 'newPage.html';
Or more simply: (since window is Global)
location.href = 'newPage.html';
If you are here because you are losing HTTP_REFERER when redirecting, keep reading:
(Otherwise ignore this last part)
The following section is for those using HTTP_REFERER as one of many security measures (although it isn't a great protective measure). If you're using Internet Explorer 8 or lower, these variables get lost when using any form of JavaScript page redirection (location.href, etc.).
Below we are going to implement an alternative for IE8 & lower so that we don't lose HTTP_REFERER. Otherwise, you can almost always simply use window.location.href.
Testing against HTTP_REFERER (URL pasting, session, etc.) can help tell whether a request is legitimate.
(Note: there are also ways to work-around / spoof these referrers, as noted by droop's link in the comments)
Simple cross-browser testing solution (fallback to window.location.href for Internet Explorer 9+ and all other browsers)
Usage: redirect('anotherpage.aspx');
function redirect (url) {
var ua = navigator.userAgent.toLowerCase(),
isIE = ua.indexOf('msie') !== -1,
version = parseInt(ua.substr(4, 2), 10);
// Internet Explorer 8 and lower
if (isIE && version < 9) {
var link = document.createElement('a');
link.href = url;
document.body.appendChild(link);
link.click();
}
// All other browsers can use the standard window.location.href (they don't lose HTTP_REFERER like Internet Explorer 8 & lower does)
else {
window.location.href = url;
}
}
There are lots of ways of doing this.
// window.location
window.location.replace('http://www.example.com')
window.location.assign('http://www.example.com')
window.location.href = 'http://www.example.com'
document.location.href = '/path'
// window.history
window.history.back()
window.history.go(-1)
// window.navigate; ONLY for old versions of Internet Explorer
window.navigate('top.jsp')
// Probably no bueno
self.location = 'http://www.example.com';
top.location = 'http://www.example.com';
// jQuery
$(location).attr('href','http://www.example.com')
$(window).attr('location','http://www.example.com')
$(location).prop('href', 'http://www.example.com')
This works for every browser:
window.location.href = 'your_url';
It would help if you were a little more descriptive in what you are trying to do. If you are trying to generate paged data, there are some options in how you do this. You can generate separate links for each page that you want to be able to get directly to.
<a href='/path-to-page?page=1' class='pager-link'>1</a>
<a href='/path-to-page?page=2' class='pager-link'>2</a>
<span class='pager-link current-page'>3</a>
...
Note that the current page in the example is handled differently in the code and with CSS.
If you want the paged data to be changed via AJAX, this is where jQuery would come in. What you would do is add a click handler to each of the anchor tags corresponding to a different page. This click handler would invoke some jQuery code that goes and fetches the next page via AJAX and updates the table with the new data. The example below assumes that you have a web service that returns the new page data.
$(document).ready( function() {
$('a.pager-link').click( function() {
var page = $(this).attr('href').split(/\?/)[1];
$.ajax({
type: 'POST',
url: '/path-to-service',
data: page,
success: function(content) {
$('#myTable').html(content); // replace
}
});
return false; // to stop link
});
});
I also think that location.replace(URL) is the best way, but if you want to notify the search engines about your redirection (they don't analyze JavaScript code to see the redirection) you should add the rel="canonical" meta tag to your website.
Adding a noscript section with a HTML refresh meta tag in it, is also a good solution. I suggest you to use this JavaScript redirection tool to create redirections. It also has Internet Explorer support to pass the HTTP referrer.
Sample code without delay looks like this:
<!-- Place this snippet right after opening the head tag to make it work properly -->
<!-- This code is licensed under GNU GPL v3 -->
<!-- You are allowed to freely copy, distribute and use this code, but removing author credit is strictly prohibited -->
<!-- Generated by http://insider.zone/tools/client-side-url-redirect-generator/ -->
<!-- REDIRECTING STARTS -->
<link rel="canonical" href="https://yourdomain.example/"/>
<noscript>
<meta http-equiv="refresh" content="0;URL=https://yourdomain.example/">
</noscript>
<!--[if lt IE 9]><script type="text/javascript">var IE_fix=true;</script><![endif]-->
<script type="text/javascript">
var url = "https://yourdomain.example/";
if(typeof IE_fix != "undefined") // IE8 and lower fix to pass the http referer
{
document.write("redirecting..."); // Don't remove this line or appendChild() will fail because it is called before document.onload to make the redirect as fast as possible. Nobody will see this text, it is only a tech fix.
var referLink = document.createElement("a");
referLink.href = url;
document.body.appendChild(referLink);
referLink.click();
}
else { window.location.replace(url); } // All other browsers
</script>
<!-- Credit goes to http://insider.zone/ -->
<!-- REDIRECTING ENDS -->
But if someone wants to redirect back to home page then he may use the following snippet.
window.location = window.location.host
It would be helpful if you have three different environments as development, staging, and production.
You can explore this window or window.location object by just putting these words in Chrome Console or Firebug's Console.
JavaScript provides you many methods to retrieve and change the current URL which is displayed in browser's address bar. All these methods uses the Location object, which is a property of the Window object. You can create a new Location object that has the current URL as follows..
var currentLocation = window.location;
Basic Structure of a URL
<protocol>//<hostname>:<port>/<pathname><search><hash>
Protocol -- Specifies the protocol name be used to access the resource on the Internet. (HTTP (without SSL) or HTTPS (with SSL))
hostname -- Host name specifies the host that owns the resource. For example, www.stackoverflow.com. A server provides services using the name of the host.
port -- A port number used to recognize a specific process to which an Internet or other network message is to be forwarded when it arrives at a server.
pathname -- The path gives info about the specific resource within the host that the Web client wants to access. For example, stackoverflow.com/index.html.
query -- A query string follows the path component, and provides a string of information that the resource can utilize for some purpose (for example, as parameters for a search or as data to be processed).
hash -- The anchor portion of a URL, includes the hash sign (#).
With these Location object properties you can access all of these URL components
hash -Sets or returns the anchor portion of a URL.
host -Sets
or returns the hostname and port of a URL.
hostname -Sets or
returns the hostname of a URL.
href -Sets or returns the entire
URL.
pathname -Sets or returns the path name of a URL.
port -Sets or returns the port number the server uses for a URL.
protocol -Sets or returns the protocol of a URL.
search -Sets
or returns the query portion of a URL
Now If you want to change a page or redirect the user to some other page you can use the href property of the Location object like this
You can use the href property of the Location object.
window.location.href = "http://www.stackoverflow.com";
Location Object also have these three methods
assign() -- Loads a new document.
reload() -- Reloads the current document.
replace() -- Replaces the current document with a new one
You can use assign() and replace methods also to redirect to other pages like these
location.assign("http://www.stackoverflow.com");
location.replace("http://www.stackoverflow.com");
How assign() and replace() differs -- The difference between replace() method and assign() method(), is that replace() removes the URL of the current document from the document history, means it is not possible to use the "back" button to navigate back to the original document. So Use the assign() method if you want to load a new document, andwant to give the option to navigate back to the original document.
You can change the location object href property using jQuery also like this
$(location).attr('href',url);
And hence you can redirect the user to some other url.
Basically jQuery is just a JavaScript framework and for doing some of the things like redirection in this case, you can just use pure JavaScript, so in that case you have 3 options using vanilla JavaScript:
1) Using location replace, this will replace the current history of the page, means that it is not possible to use the back button to go back to the original page.
window.location.replace("http://stackoverflow.com");
2) Using location assign, this will keep the history for you and with using back button, you can go back to the original page:
window.location.assign("http://stackoverflow.com");
3) I recommend using one of those previous ways, but this could be the third option using pure JavaScript:
window.location.href="http://stackoverflow.com";
You can also write a function in jQuery to handle it, but not recommended as it's only one line pure JavaScript function, also you can use all of above functions without window if you are already in the window scope, for example window.location.replace("http://stackoverflow.com"); could be location.replace("http://stackoverflow.com");
Also I show them all on the image below:
Should just be able to set using window.location.
Example:
window.location = "https://stackoverflow.com/";
Here is a past post on the subject: How do I redirect to another webpage?
Before I start, jQuery is a JavaScript library used for DOM manipulation. So you should not be using jQuery for a page redirect.
A quote from Jquery.com:
While jQuery might run without major issues in older browser versions,
we do not actively test jQuery in them and generally do not fix bugs
that may appear in them.
It was found here:
https://jquery.com/browser-support/
So jQuery is not an end-all and be-all solution for backwards compatibility.
The following solution using raw JavaScript works in all browsers and have been standard for a long time so you don't need any libraries for cross browser support.
This page will redirect to Google after 3000 milliseconds
<!DOCTYPE html>
<html>
<head>
<title>example</title>
</head>
<body>
<p>You will be redirected to google shortly.</p>
<script>
setTimeout(function(){
window.location.href="http://www.google.com"; // The URL that will be redirected too.
}, 3000); // The bigger the number the longer the delay.
</script>
</body>
</html>
Different options are as follows:
window.location.href="url"; // Simulates normal navigation to a new page
window.location.replace("url"); // Removes current URL from history and replaces it with a new URL
window.location.assign("url"); // Adds new URL to the history stack and redirects to the new URL
window.history.back(); // Simulates a back button click
window.history.go(-1); // Simulates a back button click
window.history.back(-1); // Simulates a back button click
window.navigate("page.html"); // Same as window.location="url"
When using replace, the back button will not go back to the redirect page, as if it was never in the history. If you want the user to be able to go back to the redirect page then use window.location.href or window.location.assign. If you do use an option that lets the user go back to the redirect page, remember that when you enter the redirect page it will redirect you back. So put that into consideration when picking an option for your redirect. Under conditions where the page is only redirecting when an action is done by the user then having the page in the back button history will be okay. But if the page auto redirects then you should use replace so that the user can use the back button without getting forced back to the page the redirect sends.
You can also use meta data to run a page redirect as followed.
META Refresh
<meta http-equiv="refresh" content="0;url=http://evil.example/" />
META Location
<meta http-equiv="location" content="URL=http://evil.example" />
BASE Hijacking
<base href="http://evil.example/" />
Many more methods to redirect your unsuspecting client to a page they may not wish to go can be found on this page (not one of them is reliant on jQuery):
https://code.google.com/p/html5security/wiki/RedirectionMethods
I would also like to point out, people don't like to be randomly redirected. Only redirect people when absolutely needed. If you start redirecting people randomly they will never go to your site again.
The next paragraph is hypothetical:
You also may get reported as a malicious site. If that happens then when people click on a link to your site the users browser may warn them that your site is malicious. What may also happen is search engines may start dropping your rating if people are reporting a bad experience on your site.
Please review Google Webmaster Guidelines about redirects:
https://support.google.com/webmasters/answer/2721217?hl=en&ref_topic=6001971
Here is a fun little page that kicks you out of the page.
<!DOCTYPE html>
<html>
<head>
<title>Go Away</title>
</head>
<body>
<h1>Go Away</h1>
<script>
setTimeout(function(){
window.history.back();
}, 3000);
</script>
</body>
</html>
If you combine the two page examples together you would have an infant loop of rerouting that will guarantee that your user will never want to use your site ever again.
var url = 'asdf.html';
window.location.href = url;
You can do that without jQuery as:
window.location = "http://yourdomain.com";
And if you want only jQuery then you can do it like:
$jq(window).attr("location","http://yourdomain.com");
This works with jQuery:
$(window).attr("location", "http://google.fr");
# HTML Page Redirect Using jQuery/JavaScript Method
Try this example code:
function YourJavaScriptFunction()
{
var i = $('#login').val();
if (i == 'login')
window.location = "Login.php";
else
window.location = "Logout.php";
}
If you want to give a complete URL as window.location = "www.google.co.in";.
Original question: "How to redirect using jQuery?", hence the answer implements jQuery >> Complimentary usage case.
To just redirect to a page with JavaScript:
window.location.href = "/contact/";
Or if you need a delay:
setTimeout(function () {
window.location.href = "/contact/";
}, 2000); // Time in milliseconds
jQuery allows you to select elements from a web page with ease. You can find anything you want on a page and then use jQuery to add special effects, react to user actions, or show and hide content inside or outside the element you have selected. All these tasks start with knowing how to select an element or an event.
$('a,img').on('click',function(e){
e.preventDefault();
$(this).animate({
opacity: 0 //Put some CSS animation here
}, 500);
setTimeout(function(){
// OK, finished jQuery staff, let's go redirect
window.location.href = "/contact/";
},500);
});
Imagine someone wrote a script/plugin with 10000 lines of code. With jQuery you can connect to this code with just a line or two.
So, the question is how to make a redirect page, and not how to redirect to a website?
You only need to use JavaScript for this. Here is some tiny code that will create a dynamic redirect page.
<script>
var url = window.location.search.split('url=')[1]; // Get the URL after ?url=
if( url ) window.location.replace(url);
</script>
So say you just put this snippet into a redirect/index.html file on your website you can use it like so.
http://www.mywebsite.com/redirect?url=http://stackoverflow.com
And if you go to that link it will automatically redirect you to stackoverflow.com.
Link to Documentation
And that's how you make a Simple redirect page with JavaScript
Edit:
There is also one thing to note. I have added window.location.replace in my code because I think it suits a redirect page, but, you must know that when using window.location.replace and you get redirected, when you press the back button in your browser it will not got back to the redirect page, and it will go back to the page before it, take a look at this little demo thing.
Example:
The process: store home => redirect page to google => google
When at google: google => back button in browser => store home
So, if this suits your needs then everything should be fine. If you want to include the redirect page in the browser history replace this
if( url ) window.location.replace(url);
with
if( url ) window.location.href = url;
You need to put this line in your code:
$(location).attr("href","http://stackoverflow.com");
If you don't have jQuery, go with JavaScript:
window.location.replace("http://stackoverflow.com");
window.location.href("http://stackoverflow.com");
On your click function, just add:
window.location.href = "The URL where you want to redirect";
$('#id').click(function(){
window.location.href = "http://www.google.com";
});
Try this:
location.assign("http://www.google.com");
Code snippet of example.
jQuery is not needed. You can do this:
window.open("URL","_self","","")
It is that easy!
The best way to initiate an HTTP request is with document.loacation.href.replace('URL').
Using JavaScript:
Method 1:
window.location.href="http://google.com";
Method 2:
window.location.replace("http://google.com");
Using jQuery:
Method 1: $(location)
$(location).attr('href', 'http://google.com');
Method 2: Reusable Function
jQuery.fn.redirectTo = function(url){
window.location.href = url;
}
jQuery(window).redirectTo("http://google.com");
First write properly. You want to navigate within an application for another link from your application for another link. Here is the code:
window.location.href = "http://www.google.com";
And if you want to navigate pages within your application then I also have code, if you want.
You can redirect in jQuery like this:
$(location).attr('href', 'http://yourPage.com/');
JavaScript is very extensive. If you want to jump to another page you have three options.
window.location.href='otherpage.com';
window.location.assign('otherpage.com');
//and...
window.location.replace('otherpage.com');
As you want to move to another page, you can use any from these if this is your requirement.
However all three options are limited to different situations. Chose wisely according to your requirement.
If you are interested in more knowledge about the concept, you can go through further.
window.location.href; // Returns the href (URL) of the current page
window.location.hostname; // Returns the domain name of the web host
window.location.pathname; // Returns the path and filename of the current page
window.location.protocol; // Returns the web protocol used (http: or https:)
window.location.assign; // Loads a new document
window.location.replace; // RReplace the current location with new one.
In JavaScript and jQuery we can use the following code to redirect the one page to another page:
window.location.href="http://google.com";
window.location.replace("page1.html");
ECMAScript 6 + jQuery, 85 bytes
$({jQueryCode:(url)=>location.replace(url)}).attr("jQueryCode")("http://example.com")
Please don't kill me, this is a joke. It's a joke. This is a joke.
This did "provide an answer to the question", in the sense that it asked for a solution "using jQuery" which in this case entails forcing it into the equation somehow.
Ferrybig apparently needs the joke explained (still joking, I'm sure there are limited options on the review form), so without further ado:
Other answers are using jQuery's attr() on the location or window objects unnecessarily.
This answer also abuses it, but in a more ridiculous way. Instead of using it to set the location, this uses attr() to retrieve a function that sets the location.
The function is named jQueryCode even though there's nothing jQuery about it, and calling a function somethingCode is just horrible, especially when the something is not even a language.
The "85 bytes" is a reference to Code Golf. Golfing is obviously not something you should do outside of code golf, and furthermore this answer is clearly not actually golfed.
Basically, cringe.
Javascript:
window.location.href='www.your_url.com';
window.top.location.href='www.your_url.com';
window.location.replace('www.your_url.com');
Jquery:
var url='www.your_url.com';
$(location).attr('href',url);
$(location).prop('href',url);//instead of location you can use window
Here is a time-delay redirection. You can set the delay time to whatever you want:
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Your Document Title</title>
<script type="text/javascript">
function delayer(delay) {
onLoad = setTimeout('window.location.href = "http://www.google.com/"', delay);
}
</script>
</head>
<body>
<script>
delayer(8000)
</script>
<div>You will be redirected in 8 seconds!</div>
</body>
</html>
I have an index.php with two major sections: the navbar and the main-content. The navbar contains links which will load another webpage to the main-content through this jQuery code:
jQuery('#main-content').load('sampleurl');
Some of these web pages contain links to another web page, so I want to add a back button.
I tried using the history.back() and history.go(-1), as well as the $_SERVER['HTTP_REFERER'], but they don't really work in my case.
How will I add the back button in this situation?
You should keep your last viewed page in JavaScript variable or in value of hidden input and then you only need to add button with
jQuery('#main-content').load(old_url);
You must always update your variable when you load your next page via jQuery('#main-content').load('sampleurl');
Try manipulating the javascript location or location.hash
https://developer.mozilla.org/en-US/docs/DOM/window.location
Of course, you need to be able to turn your URL back into the relevant page content too.
In conjunction with both Charlie and Michael's answers, since you are already using jQuery, another option is to include the jQuery Address plugin.
You can implement this idea, by creating a function to read a hash path to load new content. Following this, the content can be navigated by the built-in back + forward buttons.
The only challenge I foresee with this implementation is associating the new content with the hash path.
Good luck!
Just an idea: Add hash to Url whenever you load the page; and then you can use history.back()
$(function(){
if(window.location.hash === 'sampleurl'){
jQuery('#main-content').load('sampleurl', function(){
window.location.hash = 'sampleurl'; //<<-- match with your loaded page;
});
}
});
good luck !
I am building a JQuery Mobile application based on a MVC framework.
My problem is that I cannot send "redirect" directives (either HTTP, Javascript, META-refresh) to the browser.
It results in the browser displaying a single line : "undefined".
Here is the code for the redirect on the server side :
<html><head>
<script>location.href='$url'</script>
</head></html>
I know that I can fix the problem by using data-ajax=false, but i don't want that since :
I want nice Jquery mobile transitions
This is much faster in Ajax
I don't want to wonder for each link whenever the framework might send a redirect
Is there a way to make JQuery Mobile handle correctly one kind of redirect ? either HTTP, HTML META or Javascript ?
With help from the JQuery mobile community, I have came up with an elegant solution that can handle both standard HTML redirection (data-ajax="false") and JQM page transitions.
The trick is that, when doing JQM transitions, JQM loads the result HTML with javascript; searches for a page `data-role='page' and replaces it in the DOM : It ignores the HTML header.
Hence, we have to put a standard Javascript redirection in the header, and a JQM page load in a dummy page.
Here is the code of the redirection method in my MVC template :
<html>
<head>
<!-- HTML reload (for data-ajax=false) -->
<script>
location.href='<?= $url ?>'
</script>
</head>
<body>
<!-- Change page : JQueryMobile redirect -->
<div data-role="page" id="redirect">
<script>
$.mobile.changePage('<?= $url ?>');
</script>
</div>
</body>
</html>
I hope this helps someone.
Looks like this would be a better solution - from the jQuery Mobile demos.
Basically you set a http header in your redirect and look for it on pagecontainerload. This should avoid weirdness with browser history.
Here's a a href to get to the page
<a href="redirect.php?to=redirect-target.html"
data-role="button" data-inline="true">Redirect</a>
In PHP you do this
<?php
// ************************************************************************
// The two-second sleep simulates network delays, hopefully causing a
// loading indicator message to appear on the client side.
// ************************************************************************
sleep(2);
$dst = ( isset( $_GET[ "to" ] )
? $_GET[ "to" ]
: ( isset( $_POST[ "to" ] )
? $_POST[ "to" ]
: false ) );
if ( $dst ) {
// **********************************************************************
// The crucial line: Issue a custom header with the location to which the
// redirect should happen. For simplicity, we simply redirect to whatever
// location was specified in the request's "to" parameter, but real-world
// scripts can compute the destination based on server-side state.
//
// NB: This is not a HTTP redirect. As far as HTTP is concerned, this is
// a normal request/response cycle with a status code of 200.
// **********************************************************************
header( "X-Redirect: " . $dst );
}
?>
Then in your javascript you do this to intercept the URL and reset it.
$( document ).bind( "pagecontainerload", function( e, triggerData ) {
// We can use this event to recognize that this is a redirect. The event is
// triggered when jQuery Mobile has finished loading a page and inserting
// it into the DOM, but before it has altered the browser history. In this
// example the server helpfully returns a custom header. However, if you
// don't have access to the server side, you can still examine
// triggerData.page, which contains the page that was loaded, but which
// has not yet been displayed or even recorded in the browser history. You
// can also examine triggerData.xhr which contains the full XMLHTTPRequest.
// If there is a way to recognize that this is not the expected page, you
// can discard it and issue a second load() call for the page that really
// needs to be displayed to the user, reusing the options from the overall
// page change process.
var redirect = triggerData.xhr.getResponseHeader( "X-Redirect" );
if ( redirect ) {
// We have identified that this page is really a redirect. Thus, we load
// the real page instead, reusing the options passed in. It is important
// to reuse the options, because they contain the deferred governing this
// page change process. We must also prevent the default on this event so
// that the page change process continues with the desired page.
$( e.target ).pagecontainer( "load", redirect, triggerData.options );
e.preventDefault();
}
});
Note: at time of writing there was a broken link on the jquery demos page for this demo so I had to find it on github
https://github.com/jquery/jquery-mobile/blob/master/demos/navigation-php-redirect/index.php
https://github.com/jquery/jquery-mobile/blob/master/demos/navigation-php-redirect/redirect.php
The demo for 1.3 is still working http://demos.jquerymobile.com/1.3.0/docs/examples/redirect/
Basically, I want the same effect as the oldschool html 'frameset' I think.
Take a look at this page please:
http://onomadesign.com/wordpress/identity-design/alteon-a-boeing-company/
If a user selects a project from industry -> transportation for example, I would like that the right scrollmenu keeps its initial state when the new project page comes up. So they won't get lost and have to click again to be in the same submenu section.
So, the right thumbnail navigation should stay in the same way, I don't want it to reload.
Do I have to do it with frames or iframes? Or can I make some kind of jQuery call to 'not reload' that div? Maybe PHP? I'm sorry, I am not a programmer from origin.
Update:
Guys, I managed to put the whole thumbnail navigation code into a seperate php file, called sidebar.php. Now this gets called in my single.php (Wordpress) by <?php get_sidebar(); ?>.
Should it now be easier to make this sidebar.php NOT refresh on page reload? I've been looking at cookies, php sessions, iframes.. but I can't get it to work.
Any more help would be greatly appreciated!
Facebook kinda does this without frames for optimization's sake. They take every single link and, if supported, using AJAX to load the page content without reloading the layout.
Obviously, this sort of thing may require significant restructuring of the internals of your app. Another option is to simply store the menu's state as a cookie on link click (see the jQuery Cookie plugin) and, on every reload, either have Javascript look at the cookie and dynamically restore the menu to its correct state, or use your internal PHP to read the cookie and decide what menu to display.
But if you get really desperate, you may end up falling back on frames. Sometimes that can be okay - but try everything else first :)
You also can detect what menu item was activated (you got the page request due to clicking on the corresponding link) and use this information to restore/select this menu item.
At least that is what I do and... No cookies or AJAX required!
You can use a technique known as "AHAH" Asynchronous HTML and HTTP. Essentially you're doing a jQuery
$.post("whatever.html",function(data) {
$("contentdivelement").html(data);
}
You can wrap this in a function like:
updateContent(sPage) {
$.post(sPage,function(data) {
$("contentdivelement").html(data);
}
}
This will load the content from your "frame" page into the div without reloading the page.
You can also bind to each of the navigation links and use their HREF as your path to load in your content div such as:
$(".menuLink").click(function() {
var menuLink = $(this).attr('href');
updateContent(menuLink);
/* prevents the browser from taking the parent to that link */
return false;
});
ADDITION:
Your menu may look like this:
<ul class="myMenu">
<li>Frame 1</li>
<li>Frame 2</li>
</ul>
Also,
If you want it to remember the page you're on you can use cookies or #anchors. There are many ways to add "tab" or "menu" anchors but one way would just be to use a jQuery plugin.
The most COMMON and TRENDY way to do it is to use #anchors. Your browser address bar ass #frame1 to the end so when the page is refreshed or reloaded it will load up "frame1" automatically with some additional code.
You can even called the anchor #/frame1.html and read the anchor in
$(document).ready(function() {
/* you'll need to either use a plugin or parse out the anchor from your current browser address bar */
updateContent(anchorContentVar);
});
Instead of updating your content using click-handlers I suggest a slightly different approach. Just replace your hyperlinks with this kind of link:
#info_page
Now set up a simple interval that reads out the current URL and updates the DIV accordingly:
__LOC = document.location.href;
setInterval(function(){
if (__LOC!=document.location.href) __LOC=document.location.href;
var fetchURL = __LOC.split("#")[1];
$.get( "/getcontent/"+fetchURL, function(d){ $("#mydiv").html( d ); } )
} 1000);
This allows visitors to use bookmarks as well.
I am using a jquery tabbed interface here http://www.imashdigital.com/#2 and would like to return the tab number in php.
Ideally I would like to run a javascript function (on a timer) that continually updates a global php variable with the current tab.
Based on this php value, 1 through to 4, I will then load a different sidebar.
I would be grateful for any help and some code examples as I am a novice.
Kind regards

The part of an URI that comes after the hash is never sent to the server. There is no way that PHP can access it. Use a querystring parameter ($_GET) instead. Or use client side scripting (javascript).
I would suggest you do not run a timer but instead attach the $.post to the event "tab activation". This will make any tab change applied in real time and it won't trigger needless requests.
I have used tabbed panels in a couple recent projects, and the solution I've used is the following:
HTML
<ul class="tabs">
<li>English</li>
<li>Français</li>
</ul>
<div class="panel" id="en_en"><!-- Content --></div>
<div class="panel" id="fr_fr"><!-- Content --></div>
jQuery
// the currently selected tab, or a default tab (don't forget to prepend the #)
var tab = location.hash || '#en_en';
// register a click handler on all the tabs
$('ul.tabs a').click(function(event){
event.preventDefault(); // prevents the browser from scrolling to the anchor
// hide all panels, then use the link's href attribute to find
// the matching panel, and make it visible
// you can, of course, use whatever animation you like
$('div.panel').hide().filter( $(this).attr('href') ).show();
).filter('[href*='+tab+']').click();
// above: in case of refreshing/bookmarking: find the tab link that contains
// the current location.hash, and fire its click handler
It works well because the server-side code doesn't need to know which tab is selected, but it also supports refreshing or bookmarking a specific tab without requiring the user select the tab again.
