I have a problem with jQuery being lost after .load() function.
I have a element built up with jQuery UI. The problem is that when I load it from separate page like this:
$("#mydiv").load("getgroup.php?group=" + selectedGroup).html();
The getgroup.php generates something like this, depending on the GET parameter:
<select>
<option>something</option>
<option>something</option>
</select>
When loading it with load() (or post, ajax, get) the element returns unformatted... I have tried including jquery and jquery-ui plugin also in the getgroup.php file but with no luck...
Thank you
The problem is, your jquery code isn't executed automatically on dynamically loaded elements.
What you should do is, put all your jquery ui code in a function. For instance, let's say you want to call the button() jQuery UI function on the newly loaded submit elements:
function launchUiWidgets(target) {
$(target).find('input:submit').button();
}
Then, you use this function as a success callback when you load new elements - giving it target as an argument to avoid rerunning the code on all of your DOM. Let's suppose you're loading the data in a div of id "container":
$.get(
"whatever.html?name=val",
function(data){
$('#container').html(data);
launchUiWidgets('#container');
},
"html");
If my understanding is correct and the element is being inserted, but with no CSS, you may need to run .addClass after the element is loaded to apply your chosen CSS class once the element is present. However, if in your CSS you have default values for the element type predefined, e.g. select{color:#000000;width:... these should also be loaded automatically.
Per the comment below- if you are looking at your predefined handlers still being relevant for content injected by AJAX/load() calls, you can use the .live() method:

This question is kind of a duplicate, but the answer provided doesn't actually solve the issue. Here's the related question:
Why jQuery click doesn't work when included in a separate file
I've got a php template that has an overlay div I am dynamically populating with different content, depending upon which link is clicked. So for example, I have this in my template:
<a class="icon-search" href="#"></a>
<div id="overlay" class="hidden"></div>
In my global.js file, I have these functions:
$(document).ready(function(){
$("a.icon-search").click(function () {
$("#overlay").load("inc/search.php");
$("#overlay").toggleClass('show hidden');
});
$("#cancel").click(function() {
$("#overlay").toggleClass('show hidden');
});
});
The cancel button is in "inc/search.php"
When you click "icon-search", the overlay toggles properly, and the content of search.php gets loaded, but pressing the cancel button doesn't work, unless I move that function into the search.php file. I really hate doing this, because it makes the html really messy, and it makes reusing things difficult. Is there any way to overcome this issue, so that functions will work on elements that are included?
You need to use event delegation in order to have generated content fire events.
Lookup the .on() method in the jQuery documentation (http://api.jquery.com/on/)
Try this instead:
$(document).ready(function(){
$("a.icon-search").click(function () {
$("#overlay").load("inc/search.php");
$("#overlay").toggleClass('show hidden');
});
$(document).on('click','#cancel',function() {
$("#overlay").toggleClass('show hidden');
});
});
Using .on() will delegate click events on the document to the elements with the specified selector and this will work for all current elements (which are in the DOM when this code runs) and future elements (like those which are appended using AJAX, like when you use the .load() method).
The event handlers like you are using (which I call static event handlers), must be attached directly to the DOM object they are handling events for. That means that when you run the code to attach the event handler, the DOM object you want to attach to must already exist.
If you are running this code on .ready(), but your dynamically loaded content has not yet been loaded, then no event handler will be attached because there's no DOM object yet to attach it to.
There are two general approaches to solving this type of issue:
Run the code AFTER you've loaded the dynamic content (this is what putting the script into your dynamically loaded PHP content does).
Switch to using delegated event handling. In delegated event handling, you attach an event handler to a parent of the dynamic content that is itself not dynamically loaded and thus it already exists. Then, when a click happens on the dynamic content, that click will "bubble" up through it's parents and encounter the click handler you have. jQuery automates a lot of this for you when using the delegated form of .on() which is of this form $("#staticParent").on("click", "#dynamicChild", fn). You can read the details about using the delegated for of .on() in these references:
Does jQuery.on() work for elements that are added after the event handler is created?

jQuery .on does not work but .live does
The problem is this:
I have a simple, two fields form which I submit with Ajax.
Upon completion I reload two div's to reflect the changes.
Everything is working perfect except a jQuery plugin. It's a simple plugin that can be called with simple
function(){
$('.myDiv').scrollbars();
}
It's simple and easy to use, but it doesn't work on Ajax loaded content. Here is the code I use to post form and reload div's:
$(function() {
$('#fotocoment').on('submit', function(e) {
$.post('submitfotocoment.php', $(this).serialize(), function (data) {
$(".coment").load("fotocomajax.php");
}).error(function() {
});
e.preventDefault();
});
});
I've tried creating a function and calling it in Ajax succes:, but no luck. Can anyone show me how to make it work ? How can that simple plugin can be reloaded or reinitialized or, maybe, refreshed. I've studied a lot of jQuery's functions, including ajaxStop, ajaxComplete ... nothing seems to be working or I'm doing something wrong here.
If you're loading elements dynamically after DOM Document is already loaded (like through AJAX in your case) simple binding .scrollbars() to element won't work, even in $(document).ready() - you need to use "live" event(s) - that way jQuery will "catch" dynamically added content:
$(selector).live(events, data, handler); // jQuery 1.3+
$(document).delegate(selector, events, data, handler); // jQuery 1.4.3+
$(document).on(events, selector, data, handler); // jQuery 1.7+

Even if I am totally against using such plugins, which tries to replicate your browser's components, I'll try to give some hints.
I suppose you are using this scrollbars plugin. In this case you may want to reinitialize the scrollbars element, and there are many ways to do this. You could create the element again like in the following example
<div class="holder">
<div class="scrollme">
<img src="http://placekitten.com/g/400/300" />
</div>
</div>
.....
$('.scrollme').scrollbars();
...
fakedata = "<div class='scrollme'>Fake response from your server<br /><img src='http://placekitten.com/g/500/300' /></div>";
$.post('/echo/html/', function(response){
$('.holder').html(fakedata);
$('.scrollme').scrollbars();
});
If you want to update the contents of an already initialized widget instead, then things gets more complicated. Once your plugin initialize, it moves the content in some custom wrappers in order to do its 'magic', so make sure you update the correct element, then trigger the resize event on window, pray and hopefully your widget gets re-evaluated.
If it doesn't help, then try to come up with some more details about your HTML structure.
I want to thank everyone of you who took their time to answer me with this problem I have. However, the answer came to me after 4 days of struggle and "inventions" :), and it's not a JS or Jquery solution, but a simple logic in the file.
Originally, I call my functions and plugins at the beginning of the document in "head" tag, like any other programmer out here (there are exceptions also ).
Then my visitors open my blog read it and they want to post comments. But there are a lot of comments, and I don't want to scroll the entire page, or use the default scroll bars, simply because they're ugly and we don't have cross browser support to style that, just yet.
So I .post() the form with the comment, and simply reload the containing all of them. Naturally .scrollbars() plugin doesn't work. Here come the solution.
If I put this :
<script>$('.showcoment').scrollbars();</script>
in the beginning of my loaded document (with load() ), will not work, because is not HTML and it's getting removed automatically. BUT !!! If i do this:
<div><script>$('.showcoment').scrollbars();</script></div>
at the same beginning of loaded document, MAGIC .... it works. The logic that got me there I found it in the basics of javascript. If your script is inside an HTML element, it will be parsed without any problem.
Thank you all again, and I hope my experience will help others.
If I understand you correctly, try this:
var scrollelement = $('.myDiv').scrollbars();
var api = scrollelement.data('jsp');
$(function () {
$('#fotocoment').on('submit', function (e) {
$.post('submitfotocoment.php', $(this).serialize(), function (data) {
$(".coment").load("fotocomajax.php");
api.reinitialise();
}).error(function () {
});
e.preventDefault();
});
});
reinitialise - standart api function, updates scrolbars.
I have a PHP query that displays the first 30 documents, then an anhor which loads the rest of the documents using jQuery load.
Although, the parent uses javascript for some effects. Although once loaded onto the document it doesn't seem to inherit it's script tags.
is there any solution for this?
you have to put your "effects" into a function, then in the success of the load you have to call that function again.
function effects(){
//all your effects
}
$('#result').load('ajax/test.html', function() {
effects();
});
OK, so I am having some trouble getting my head round a solution to get a certain jQuery plugin to work after an AJAX call has been successful and placed the data into the DOM.
The plugin is jScroll and I am sure that this plugin only identifies the element call upon on page load, so if the element is loaded into the DOM through the AJAX call the plugin will not recognise the it thus not working.
I sthere any way round this that does not require a re-writing of the code?
Could you do something like -
$.get('ajax/test.html', function(data) {
$('.result').html(data);
$('.result').jscroll()
});
Which would get the result from the server add it to an element, then set up the jScroll functionality on that element.
I've got some dynamic content inside a tabber (http://www.barelyfitz.com/projects/tabber/).
All works fine, but I want to reload the div which contains the tabber. When I do this, using jQuery AJAX, the data updates, but the tabs are no longer formed. Do I have to reload the javascript elements of the page, and if so how do I got about doing this?
Thanks! :)

Your AJAX function is probably replacing the contents of the div with new elements (so they lose any initialization that you've done).
In your AJAX callback, just re-initialize tabber. From glancing at their web-page it looks like you just need to call the function tabberAutomatic(tabberOptions);
I think something like this will do the trick:
$("#myDiv").load("/my/remote/data.json", function(){
tabberAutomatic();
});
