I need to learn how to initialize scripts. I have google it but dont dont really understand it.
Right now I have a toggle-script that is in a div, that entire div gets loaded in to another page. The toggle scripts work, but not when its loaded in.
$(".class").click(function () {
$(this).toggleClass("add_class");
});
If somebody have time, can you explain to me how to initialize this script?
Thanks.
You should put this script inside a document.ready call.
Eg.
$(document).ready(function() {
//Put your code here
});
If I misunderstood your question and what you actually mean is:
How do you execute the script after you load it in through an AJAX call.
Then see this question: executing script after jQuery Ajax Call
Are you calling it after the elements are loaded on the page?
You should be using on() with jQuery 1.7+
$(document).on("click", ".class", function () {
$(this).toggleClass("add_class");
});
If you want to keep your syntax, you would have to do it either after the elements are rendered, or do it on document.ready.
I figure you're using jquery.ajax to fetch the div?
If so, you should be able to add the listeners in the success-function of the jquery.ajax call:
$('#result').load('ajax/test.html', function() {
$("#result .class").click(function () {
$(this).toggleClass("add_class");
});
});
simple and best
$(function(){
//your code here...
$(".class").click(function () {
$(this).toggleClass("add_class");
});
});

I am loading the new.html page using ajax load method and then tried to change the content of the div#rr but it did not work!
any solution ?
why your code $('#rr').html('modfied'); is not working because you are calling the change before jquery ajax.load() method is able to load the content from your new.html and as result your id #rr is not found. So, instead of calling the modify code after the load statement call the modifying statement in your load()'s complete()
as:
$('#btn').on('click', function () {
$('.container').load('new.html', function () {
$('#rr').html('modfied');
});
});
and please go through the jquery documentation for more info on how to use the functions Jquery Documentation for Load() funciton.
Try to call the function inside the ajax call function.
$('.container').load('new.html',function(){
$('#rr').html('modified')
});
next time please do not put image for code.
I have Jquery function that executes AJAX query to server.
How can I call this after load page in the specified url page? May I bind this to element HTML, I mean:
<div id="graph" onload="function()"></div>
jQuery handles the HTML file with a variable called document.
Document has two popular event states
load when the page has been loaded
ready when the page has been loaded and all other decorations to the HTML have been applied.
jQuery provides hooks for these states.
To run javascript code after each of the events listed above, you have to put the function within the appropriate event scope.
For loading, this would be…
$(document).load(function() {
// javascript code you want to execute
})
After the page has been ready, but not yet rendered, you can apply some other javascript code using
$(document).ready(function() {
// javascript code you want to execute
})
One way using jQuery:
$(document).ready( function() {
//do whatever you need, you can check if some element exists and then, call your function
if($("#graph").length > 0)
callfunction();
});
No jQuery, only vanilla js:
window.onload = function() {
if(document.getElementById("graph"))
callfunction();
}
I have 2 external html pages loaded by this code:
<div id="header-div"></div>
<div id="footer-div"></div>
my js file contains this:
$(function () {
$("#header-div").load("/AfekDent/header.html");
$("#footer-div").load("/AfekDent/footer.html");
});
I want to run a function when specific element in the header file is created -
what trigger can i use for it?
It's ok the trigger will occur when all elements will be loaded.
thanks!
Add a callback to your load() call.
$(function () {
$("#header-div").load("/AfekDent/header.html", function() {
console.log('My header was loaded!');
});
});
You can use a callback on the #header-div, which will execute the code after the entire header has loaded.
$("#header-div").load("AfekDent/header.html", function() {
someFunction();
});
However, if you want to execute code after a specific element in the header loads, try something like:
$("#specific-element").on("load", function() {
someOtherFunction();
});
If you want to learn more about the difference between load and on("load"), look at this question or read the jQuery documentation for load and on().
For simplicity, I'd recommend executing code with $(document).ready(function() {yetAnotherFunction();});, but it depends on your specific case.
I have a dilemma - my javascript code needs to be executed when the DOM is ready. However, at the same time I need to be able to hook up to the load event of another script. So hypothetically speaking I need something like this:
ExecuteOrDelayUntilScriptLoaded(getData, "sp.js");
function getData() {
(document.ready(function() {
//my code to get data from sharepoint list.
}));
}
Only the latter does not seem to work.
Please suggest!
Why not to do it like this?
$(document).ready(function() {
ExecuteOrDelayUntilScriptLoaded(function getData(){
//your code to get data from sharepoint list.
}, "sp.js");
});
Try
$(document).ready(function() {
$.getScript('sp.js', function() {
//your code to get data from sharepoint list.
});
});
For even more control over script loading, try a script loader like the simple and lightweight yepnope.js or the more complex LABjs.
If you are using jQuery, MooTools, or any other library - there is a standard function you can hook into, which checks if the DOM and your assets are loaded.
For example, in jQuery:
http://api.jquery.com/ready/
I'm currently working on a little product display page that loads prettyPhoto-enabled galleries through ajax. The problem is, prettyPhoto doesn't work on the images added after the page loads initially. I understand that I need to re-initialize prettyPhoto after the new content loads, but how? I've tried adding prettyPhoto.init(); to the code that is returned to the page - that doesn't work.
Page I'm working on is here: http://turningpointpro.com/page.php?id=10
I ended up finding two solutions. The first and best was to put this whole bit:
$(document).ready(function(){
$("a[rel^='prettyPhoto']").prettyPhoto();
});
into the ajax callback, not the prettyPhoto.init(); function I was calling before.
I also had some luck with using the API instead of re-loading prettyPhoto again.
Hope this helps someone.
If you are using ASP.NET with Ajax, the scriptmanager will allow you to use a function called pageLoad() that is called every time the page posts back (async or otherwise).
your code:
function pageLoad()
{
$("a[rel^='prettyPhoto']").prettyPhoto();
}
$(function() {
$('#navigation a.button').click(function(e) {
$.get( $(this).attr('href'), function(data) {
$('#portfolio').quicksand( $(data).find('li'), { adjustHeight: 'dynamic' }, function(){ $("a[rel^='prettyPhoto']").prettyPhoto(); } );
});
e.preventDefault();
});
});
