I have a drop down user menu that contains child links that I cannot get to redirect properly. I unfortunately did not code the front-end, so I'm just trying to get it to link to dynamic PHP urls. I'm also working within the CodeIgniter framework, by the way. There are two clicks in the user's process (similar to Google's user icon). 1. You click the user image and drop down arrow, 2. You see profile, settings, logout.
With the following script, clicking the drop-down arrow redirects to the first link, profile, without even doing the drop-down animation. Any thoughts?
Here's the PHP file:
<div class="user css3">
<img src="images/user.jpg" alt="user" class="css3" />
<div class="child css3">
<ul class="user_links">
<li>Profile</li>
<li>Settings</li>
<li>Logout</li>
</ul>
</div>
</div>
Here's the JavaScript for drop-down arrow button:
$('div.user').click(function() {
$('div.user div.child').slideToggle("fast");
$('div.live div.action div.category div.child, div.live div.action div.sort div.child').slideUp();
return false;
});
Here's the JavaScript that I came up with for the <ul> (I'm not much of a JS dev. haha):
$('ul.user_links li a').click(function() {
document.location($(this).attr("href"));
});
Any thoughts are greatly appreciated!
I said in the comments:
Remove the js for the <ul>, and then return false from the other block, and it should work.
Here is why: when you click an anchor, the event starts propagating upwards through the document structure (the DOM). When it reaches another element wired to catch the click event, it runs this element's event handler.
When you click the anchor, the click handler on div.user runs. The last statement there, return false, means "stop the event propagation, and prevent the default behavior". On an anchor, the default behavior would be to follow the link. Your code told the browser not to do it.
Not sure if this is the root cause, but anyways use:
window.location = $(this).attr("href");
Instead of
document.location($(this).attr("href"));
try adding an onclick event to the drop down that returns false, thus stopping the default action for links.
<img src="images/user.jpg" alt="user" class="css3" />
Or changing it so it's just a 'span' tag instead of a 'a' tag. You'd have to change the JQuery selector that causes the drop down as well so that it looks for 'span' instead of 'a'
I'm not sure why you need change the default behaviour of the links 3 links though, they would redirect to the href location anyway surely?

The questions similar to that I found a lot but still can not realize what I need. I have a page.php that loaded in the block din_content with function .load
Page.php
<div id="ess">
<div id="top_ch">
<h1>Ess</h1>
</div>
<div id="ch">
<iframe name="users" width="220" height="510" align="left" src='ess/users.php' id="userch"></iframe>
<iframe name="text" width="450" height="405" src='ess/text.php'></iframe>
</div>
In page I have two Iframes. So I have two problems. First in main page where that iframes loaded I have Jquery function
$(document).on('click','.link_pro',function () {
//some actions
});
How to make that that function also worked in iframe?
Second, In the first Iframe I have two links. So what I need is that depend of what link you click on, the variable 'active' changed and depend on the value of that variable changed the second iframe. In example, you click on the first link and variable 'active' =1 than it transfered to the second iframe (may be even transfer to the parent and try to send to the second iframe trough method Get) where depend of the value displayed a requested result. I try to realize it with jquery and php. But still didn't get the result. The most problem to get a result from clicking on links in the first Iframe.
If you own the iframes sources and they belong to the same domain as the top window, then, for attaching events, you could probably do something like:
jQuery("iframe").load(function(){
jQuery(this).contents().find(".link_pro").on("click", function(){
});
});
The code above will attach the click event to your iframe's content (.link_pro).
Then, for the second question, if you have, for example, in your top window:
var myTopVar; //This belongs to top window scope
From your iframe, you can access:
top.myTopVar;
I think that should be it but, again, both your top window and iframe should share the same domain (document.domain). If not, you will face same origin policy problems.
I have jQuery site here. I have 4 links with in ul tag. Within this link, I need to inactive a link but have to show. See below:
<div class="over hide" id="waterSecondOver">
Overview
Local Area
Floor Plans
<a href="javascript:void(0);" id="chancingallery" >Gallery</a>
</div>
I have a click function on the above links (except the 4th one i.e gallery). See the code
JQR('#waterSecondOver a').click(function() {
// my code
});
Here I need to show the gallery link, but nothing happens when click on the gallery (i.e must be inactive link or what I say it's functionality is only show the link as "gallery ")
I think it's clear . Please help me
JQR('#waterSecondOver a').click(function(event) {
event.preventDefault();
});
Don't set hrefs in the anchor tags to javascript:void(0); - this is messy because it's needless repetition. With jQuery, it's possible to use return false; in your event callback to avoid the default click event taking you to a new page or the current one. While this is the easiest method, it's not always the best. See this article for more info:
http://fuelyourcoding.com/jquery-events-stop-misusing-return-false/
But you definitely don't want to be setting href manually.
I would simply change the class of the anchor(lets say class="active") and everytime onclick check for that "active" class. If the class is "active" do nothing else DO SOMETHING.
You can do this way for simplicity...
JQR('#waterSecondOver a').click(function(event) {
if(JQR(this).attr('id') == "chancingallery"){
// inactive all links except the one you dont want
}else{
// whatever you need....
}
});
I have an overlay popup box (DIV + JavaScript + some CSS) which is toggled by a link, like this:
<a href="#" onclick="popup('popUpDiv')">
The box that pops up contains an iframe. Now I want different links on my page to load different iframes when the box opens; so that link A would toggle the box to appear, and load iframe1.html inside the box, while link B would toggle the same box to appear, but load iframe2.html inside the box, and so forth.
I'm a beginning programmer, and I first figured maybe this could be done with PHP, by putting something like this inside the popUpDiv:
<iframe src="http://mysite.com/iframe<?php echo $_GET ["iframeid"] ?>.html">
... and then simply adding ?iframeid=x to each link's href, where x is the id of the iframe to be loaded.
This obviously won't work in practice though, because it requires a page reload, and when the link is clicked, the popUpDiv is toggled to open, but at the same instant, the page reloads, now with the ?iframeid=x query string in place, but too late, since the popUpDiv disappeared on reload.
Is there perhaps a JavaScript equivalent that could be used, or can anybody suggest another way to make this work?
FYI, this is the kind of popup box I'm working with:
http://www.pat-burt.com/csspopup.html
I finally found a really simple way of accomplishing this without additional JavaScripting, by simply using the target attribute:
<iframe name="myfavoriteiframe">
Then:
This is a link.
P.S. Just FYI for any of those out there who might want to use this feature with Vimeo's JavaScript API, as I'm doing: In order to make API buttons work with this target method, it seems like the iframe src-attribute cannot be left blank. You need to specify a link to any of your videos in the src, so that a video loads into the iframe on page load, like this:
<iframe name="myfavoriteiframe" id="player_1" src="http://player.vimeo.com/video/[the_number_of_your_video]?api=1&player_id=player_1">
I simply inserted the URL to the first video on my page, but you can use any of them, since they're hidden anyway.
Then link to any of your videos using the target method described above, and the pre-set iframe video will be replaced by a video of your choice.
Create two divs with the two variations of content (the two iframes with each specific URL). Then toggle by the name of the div.
<a href="#" onclick="popup('popUpDiv1')">
<a href="#" onclick="popup('popUpDiv2')">
Set the id attributes of the div elements appropriately.
Rather than adding something to the popup DIV element, I would add a required link to the href property of the link that you use to open the popup:
<a href="http://example.com/first/uri" onclick="pre_popup('popUpDiv')">
<a href="http://example.com/first/uri" onclick="pre_popup('popUpDiv')">
<a href="http://example.com/first/uri" onclick="pre_popup('popUpDiv')">
And then inside the popup function I would take the href parameter of the link that has triggered the event and use it in a popup:
function pre_popup(id) {
// Take the href parameter of the link
var href = this.href;
// And then use it in the iframe
window.frames["your_iframe"].src = href;
// And then pop it
popup(id);
}
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){ $("#mydiv").html( d ); } )
} 1000);
This allows visitors to use bookmarks as well.
I am using a jquery tabbed interface here http://www.imashdigital.com/#2 and would like to return the tab number in php.
Ideally I would like to run a javascript function (on a timer) that continually updates a global php variable with the current tab.
Based on this php value, 1 through to 4, I will then load a different sidebar.
I would be grateful for any help and some code examples as I am a novice.
Kind regards
Jonathan
The part of an URI that comes after the hash is never sent to the server. There is no way that PHP can access it. Use a querystring parameter ($_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.
