I have an AJAX loaded DIV.
When on this page I can make some changes that involve table updates and after I make then I call the following code to refresh the DIV.
It does fadeout/in and ajax loader appears etc but the contents of the page remains the same.
Appears the .load() isn't getting a fresh copy of the php file from the server as it requires a refresh for the updated data to appear.
Any ideas how I can get the DIV to refresh? thx
function reloadDIV() {
var ajaxgifloader = $('img#ajaxgifloader');
var contentwrapper = $('div#contentwrapper');
ajaxgifloader.show();
contentwrapper.fadeOut('fast',
function() {
contentwrapper.load('scripts/php/admin_sitearticles.php',
function() {
contentwrapper.fadeIn('slow');
ajaxgifloader.fadeOut();
});
});
}
my appologies - I had the wrong path to the PHP file - thus no new contect... thankyou for tolerating me!!

My goal: I have a form that is in parts, 1-4, when the user clicks on the "Next" button I would like the content to animate out then part 2 slides, and so on until the form is complete. The tricky part is I would am trying to use a different php page in a different subfolder to insert as the other 3 parts. This would also change the URL subfolder the user sees.
The working example is actually WordPress. When you click through the multi-part form you will see the content and the URL act as I have described.
I did a bit of digging and it seems like they used React.js on the content but I couldn't really find any documentation on how to do this with React.js so it made me think that maybe it was custom Ajax/jQuery or what.
My Trees of Folders -
Main
Subfolder-1
index.php
Subfolder-2
index.php
And so on. The only thing I could think of would to use jQuery:
$(document).ready(function() {
$('#form-container').on('click', '.insert', function() {
var directory = $(this).attr('name');
$('#form-container').load('../' + directory);
return false;
});
});
I add the class of "insert" on the "Next" button and give it a name="Subfolder-2" $('#form-container').load('../Subfolder-2);' will actually load the content into the div without the page refreshing BUT it does not change the subfolder in the URL.
Am I on the wrong track? Maybe I am just not searching for the right thing?
Ok, so I ended up figuring out how to get the content to act like I wanted with the information John S. provided me. After doing some research and a few hours of trial and error I came up with the JavaScript below:
var data = 'start',
url = '../' + data + '/';
history.pushState(data, null, url);
Above I set the variables and immediately run a history.pushState on page load to capture the first div that is loaded into the content div. This is important because it is the only way I could load the content that happens on initial load back into the page when hitting the browsers back button.
$('body').on('click', '.insert', function(e) {
data = $(this).attr('data-name'),
url = '../' + data + '/';
history.pushState(data, null, url);
request_content(data);
return false;
});
Then I add a click listener to the button with the class .insert reset the variables so instead of grabbing the page that initially loaded it grabs the page that will be loaded, then use history.pushState again to change the url that is determined by the variables.
The request_content function is a simple .load function. So when the button is clicked the variables are set, the url changes and the new content get loaded into the page while the old content disappears.
The final piece to the puzzle which took me the longest to figure out is actually the popstate function. I am still not 100% sure why it works but after hours of messing with it and finally getting it to work I am not going to question it.
window.addEventListener('popstate', function(e){
var data = e.state;
if(data === null) {
} else {
request_content(data);
}
});
This popstate function is what allows the content to come back when hitting the browsers back or forward navigation.

Thanks again to John S. for pointing me in the right direction!
I want to remove a some record from my database while clicking on delete button. Currently I am using this code:
function removeItem(id) {
$.ajax({
url:"removeItem_checkOut.php",
type:"GET",
data:"id="+id,
success:function(content) {
window.location.reload();
}
});
}
In removeItem_checkOUt.php I am simply running the delete query.
It works fine for me, but the problem with this code is that it reload the entire page. I just want to do it without reloading the page.
Simple saying is this that the functionality of the above code is good but i am unable to do it without the reloading the page. Until the page reload, it is does not disappear for the page.
Can anyone help me please....
Remove the "window.location.reload();" line from your success callback.
This line is telling your ajax call to reload the window after it has been successfully executed.
function removeItem(id) {
$.ajax({
url:"removeItem_checkOut.php",
type:"GET",
data:"id="+id,
success:function(html) {
$('#div_contains_data').html(html); //put your div id of the content (if it is a table use that table inside a div)
}
});
}
and in your removeItem_checkOut.php print again the same data part that the div contains(here assumed as table.so print the table in your php file again).
I'm working on an ajax loading function on a Wordpress single page portfolio.
The principle is that when you click a thumbnail in the gallery, it opens a container (#DrawerContainer) and fetch the ajax content of this article into it. With a lot of help, I'm already able to open the drawer and load the post content when I click a thumbnail.
Here is a fiddle if you want to see it working (the ajax will not load but it works locally). http://jsfiddle.net/RF6df/24/
The part I'm working on now: I need my site to be crawlable and the urls to be shareable. If I give http://mywebsite.com/#!project5 to someone, I need project5 content to be opened when he loads the page.
I thought the hash-bang (#!) urls was the way to go to make this work. With the code below (commented on the jsfiddle), I can update the url and add the hash of the clicked thumbnail.
var pathname = $(this).find('a')[0].href.split('/'),
l = pathname.length;
pathname = pathname[l-1] || pathname[l-2];
window.location.hash = "#!" + pathname;
But when I load a page, the ajax state isn't remembered. I assumed it was because my ajax container was only loaded on click event, but there is no change when I add a persistant container in the php.
Is there a way to load the page with a post content already displayed, or to open the #DrawerContainer when the page is loading a hash-bang url?
Please keep in mind that I'm just learning jquery and ajax. So I'd really appreciate if you explain or comment a little bit what you do, I'll for sure learn at the same time... :)
on onload you should check the window.location.hash and trigger a click on the particular link/div.
$(document).ready(function() {
var hash = window.location.hash;
if ( hash.length > 0 ) {
hash = hash.replace('#' , '' , hash );
$('a[rel="'+hash+'"]').trigger('click');
}
});
I have used the following on sites where I want to trigger via hash changes.
First I bind a hashchange event to get the hash value
$(window).bind('hashchange', function(o){
url = window.location.hash.substring(1);
o.preventDefault();
if (!url) {
return;
}
}
Then I trigger the hashchange when I want - in your case when the page loads i.e. on document ready.
jQuery(document).ready(function($) {
$(window).trigger('hashchange');
});
You can then use the hash value in your function that loads the correct content
Sorry if title is not too clear but I think it's about right. NEhow, what I would like to do is a bit like (well is to a certain extent) building a widget with JQuery (pref), PHP & CSS.
What I would really like to happen is for a "member" of my site to simply paste 2 lines of code in their HTML to load the widget. Something like this:
<script type="text/javascript" src="http://www.mydomain.com/script.js"></script>
Then to display the widget something like this <div id="displaywidget"></div>
OK that bit is "easy" and ok. But how do I include JQuery or "something" to generate the widget in script.js
What I mean is "displaywidget" - the ID of the widget div will be the name of a php file on my server so essentially script.js will need to load displaywidget.php into the div displaywidget.
I think I use document.getElementById('displaywidget') to get the div but how do I then "write/insert/load" displaywidget.php inside the div?
Thinking as I write "pure" java can do "most of what I want i.e. document.getElementById('displaywidget'), BUT I would prefer to also "include" Jquery.js as I would like some aspects of the widget to use JQuery. Example being the JQuery UI date function.
Sorry if I am rambling a bit but trying to think as I go along. My "real" problem is I am not too sure on "pure" javascript i.e. getting the div to display/load displaywidget.php
Suggestions please. (Oh if I am barking up the wrong tree please feel free to tell me - nicely:) )
Thanks in advance

You're looking for the AJAX behaviors inside of jQuery which would make the call to the php page and then push the data into the div.
You should be loading jQuery early on in the process, right up front in your head element. Once its loaded it will be cached so no worries of its on every page. No real overhead incurred.
Once jQuery is installed you can call one of many AJAX functions related to obtaining data and popluation elements. Theres $.load(), $.ajax(), and a few others that escape me unless I go and check out their docs section.
You can do all of this without jQuery, but its more code and you have to control for browser differences.
You can load jquery into script.js, just copy and paste it after or before whatever javascript lives in script.js.
So if script.js is:
//start of file
alert('ex');
//end of file
Make it:
//start of file
alert('ex')
Copy and pasted Jquery source
//end of file
After a bit more "trawling & thought" I found this code:
(function() {
// Localize jQuery variable
var jQuery;
/******** Load jQuery if not present *********/
if (window.jQuery === undefined || window.jQuery.fn.jquery !== '1.4.2') {
var script_tag = document.createElement('script');
script_tag.setAttribute("type","text/javascript");
script_tag.setAttribute("src","http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js");
script_tag.onload = scriptLoadHandler;
script_tag.onreadystatechange = function () { // Same thing but for IE
if (this.readyState == 'complete' || this.readyState == 'loaded') {
scriptLoadHandler();
}
};
// Try to find the head, otherwise default to the documentElement
(document.getElementsByTagName("head")[0] || document.documentElement).appendChild(script_tag);
} else {
// The jQuery version on the window is the one we want to use
jQuery = window.jQuery;
main();
}
/******** Called once jQuery has loaded ******/
function scriptLoadHandler() {
// Restore $ and window.jQuery to their previous values and store the
// new jQuery in our local jQuery variable
jQuery = window.jQuery.noConflict(true);
// Call our main function
main();
}
/******** Our main function ********/
function main() {
jQuery(document).ready(function($) {
******* Load CSS *******/
var css_link = $("<link>", {
rel: "stylesheet",
type: "text/css",
href: "style.css"
});
css_link.appendTo('head');
/******* Load HTML *******/
var jsonp_url = "http://al.smeuh.org/cgi-bin/webwidget_tutorial.py?callback=?";
$.getJSON(jsonp_url, function(data) {
$('#example-widget-container').html("This data comes from another server: " + data.html);
});
});
}
})(); // We call our anonymous function immediately

I'm using jQuery to dynamically load php pages into my page using the .load() function, so far this has been successful but if you click on various links to update the div with the .load() it starts to flicker between the new clicked page and the old one, this is pretty annoying and has anyone got a fix?
Current code:
$(document).ready(function(){
$('a').click(function() {
$('#content').load($(this).attr("href"));
return false;
});
});
The flickering is possibly caused because the dimensions of the #content div vary between loads, try to slideTogle it before loading or use another transition between loads
example :
$(document).ready(function(){
$('a').click(function() {
$('#content').slideUp('slow',function(){
$('#content').load($(this).attr("href"),function(data){
$('#content').slideDown('slow');
});
})
return false;
});
});
I hope it is ok to question the premise. You're making all links use ajax to replace #content's contents? Doesn't that break the browser's forward/back button behavior? If so, I personally would not like to use such a site.
