jQuery bind event not firing on elements loaded via $().load()

I have a DIV that is in an .html file that is loaded into my document via:
$(document).Ready( function() {
$("#contentDiv").load("some.html")
//some.html contains a button id=saveButton
$("#saveButton").click( function () {
alert("Here I am!");
}
});
The event will not fire. If I cut the content of some.html and put it in the document, uhm, "physically", the event will fire.
So, I am pretty sure this issue is related to the fact that the html is injected via .load().
It's bothersome, because if you look at the page source, all the HTML is in fact there, including the button.
So, the question is, is there ANY way to make this work? I am using .load() to reduce page complexity and increase readability, and, code-folding notwithstanding, I really do not want to have to pull all this HTML into the document.
EDIT: This code was just typed in off the cuff. It's not a cut-n-past of the actual code, and it is just to demonstrate what the problem is. But, thanks for pointing it out.
EDIT2: Grrrrrrr. });

load() is asynchronus so you need to the job in the callback :
$(document).ready(function() {
$("#contentDiv").load("some.html", function(){
//some.html contains a button id=saveButton
$("#saveButton").click( function () {
alert("Here I am!");
});
});
});
Hope it helps :)

one way is by adding to the some.html the script line which will be loaded as the div appears.
You can add this script to some.html(in a script tag):
registerButton();
and then you can define registerButton() in your current document.
other way, if I remember correctly is by using something like the function bind( )

If you want to fire event on element which was not available at the time when DOM was ready then you need to use .on event.
http://api.jquery.com/on/
$("#saveButton").on("click", function() {
alert("Here I am!");
});

jquery load() function is asynchronous. If you want to bind events to the loaded content, you should put the code into the callback function:
$(document).ready(function() {
$("#contentDiv").load("some.html", function() {
//you should put here your event handler
});
});

Your issue is that jquery load() function is asynchronous as #lucas mention. But his code has syntax errors, try this:
$(document).ready(function () {
$("#contentDiv").load("some.html", function () {
$("#saveButton").click(function () {
alert("Here I am!");
});
});
});
Hope it helps now

You need to bind the event handler either after the load OR to the container of the HTML from the load
$(document).ready(function() {
$("#contentDiv").load("some.html", function() {
$("#saveButton").on('click',function() {
alert("Here I am! Bound in callback");
});
});
});
OR use: (not needed that it be in the document ready just that the contentDiv be present)
$("#contentDiv").on('click','#saveButton',function(){
alert("Here I am! bound to container div");
});
EDIT: load on the SAVE button click (per comments) (this makes no sense though)
$(document).ready(function() {
$("#saveButton").on('click',function() {
$("#contentDiv").load("some.html", function() {
alert("Here I am! Bound in callback");
});
});
});

Dynamically created div behavior on button click

I went through many post from SO but not able to relate with my scenario.
I have this code on button click. by which User can create as many div on runtime as he wants to on UI.
$('#adddiv').click(function () {
debugger;
$('#main').append('<div class="ara-dynamic-div">
<div class="box box-solid bg-light-blue-gradient">
</Div></div>');
});
code to get buttonclick event from that div
$(document).on('click', '#remove', function () {
showMakeAndHold(this);
});
function showMakeAndHold(obj) {
alert(obj);
$('.ara-dynamic-div').fadeOut();
}
Now the problem is that I have to create multiple dynamic div. and each div will have button to close itself. When I call this function it will close all created div's instead of the one which button is clicked.
I am not able to find the proper div by which request for close come. I am new to DOM and JQuery. not able to relate the things

First of all, if you're using multiple divs you shouldn't give the close button an ID, but a class instead (let's say, .close)
Next you can use event delegation to find the correct element:
$(document).on('click', '.ara-dynamic-div .close', function( event ) {
$(this).closest('.ara-dynamic-div').fadeOut();
} )
The delegator handles all click events in any .ara-dynamic-div .close button, catching them all and allowing you to use $(this).closest(...) to get to the parent container.
Edit: Corrected a mistake

You can use jQuery's .closest() function.
function showMakeAndHold(obj) {
alert(obj);
$(obj).closest('.ara-dynamic-div').fadeOut();
}
JSFiddle

Replace this:
$(document).on('click', '#remove', function () {
showMakeAndHold(this);
});
by this:
$(document).on('click', '#remove', function () {
$(".ara-dynamic-div").not($(this).parents(".ara-dynamic-div")).fadeOut(function () {
$(this).remove();
});
});
Here is the JSFiddle demo
What the code does is that it remove all other .ara-dynamic-div except the one for which the button was clicked.

jQuery Script in External .js file not firing

I have a small piece of script in an external .js file that will not run. Here is the script:
$(document).ready(function () {
$('#chkAllTracts').change(function () {
alert("fired");
})
});
I have a number of other functions in the same .js file that use some jQuery and they all work fine but this is the first jQuery I have attempted to use inside this syntax:
$(document).ready(function (){ }
All I am trying to do is make an alert open when a checkbox is changed (checked or unchecked). The checkbox element "chkAllTracts" is added dynamically using jQuery before this function is called.

$('#checkbox1').mousedown(function() {
if (!$(this).is(':checked')) {
alert("test")
}
});
something like that? (edited)

This worked for me:
$(document).ready(function(){
$("body").append(
$("<input>")
.attr("type", "checkbox")
.change(function(){ alert("It works!"); }))
});
When the document is ready it includes in the body the checkbox input with the change event set to fire the alert message.

It is because your element is dynamically added to the DOM. jQuery selectors would not get hold of it when jQuery first initialise. What you need to do is
$('body').find('#chkAllTracts').change(function () {
alert("fired");
});
I think that should solve your problem.

PopUp is not opening on mousehover

I am not sure what i am doing wrong here.i have a div and i want to open up a popup if user hover over that div section and want to close on mouseout. here is my code
<div class="topCart">
some data
</div>
this is my JQuery code
$(".topCart").mouseover(function() {
$.get('${rolloverPopupUrl}?bustcache=' + new Date().getTime(),
function(result) {
$('#viewCart').html(result);
refreshMiniCart();
});
$('#viewCart').slideDown('slow');
}).mouseout(function() {
$('#viewCart').slideUp('fast');
});
above code is not working nor its giving any Ajax call to fetch fresh data, while if i use following code
$(document).ready(function(){
$(".topCart").hover( function () {
$('#viewCart').html("");
$.get('${rolloverPopupUrl}?bustcache='+new Date().getTime(), function(result){
$('#viewCart').html(result);
refreshMiniCart();
});
if($('#viewCart').is(':hidden')){
$('#viewCart').slideDown('slow'); }
},
function () {
$('#viewCart').slideUp('fast');
});
});
this piece of code is working and its fetching data so i do not see use of document.ready
with my limited knowledge of Jquery i tried but not able to see the reason of not working of code
can any one point me my error?

Try having some basic structure and cleanliness (which is next to godliness) when typing your code, and spotting errors will be much easier:
$(function() {
$(".topCart").on({
mouseenter: function() {
var elem = $('#viewCart');
elem.empty();
$.get('${rolloverPopupUrl}?bustcache=' + new Date().getTime(), function(result) {
elem.html(result);
refreshMiniCart();
});
if (!elem.is(':visible')) elem.slideDown('slow');
},
mouseleave: function() {
$('#viewCart').slideUp('fast');
}
});
});​

The first code does not work becuse not all DOM elements are downloaded when you set events. And it cause that result of $(".topCart") is empty. This not fire any erros, syntax is correct, problem is jQuery works with html, that are not completed.
$(document).ready(...)
or
$(function() {
// Handler for .ready() called.
});

$(document).ready(function() {
$(".topCart").mouseover(function() {
...
}
});
You need to use the document.ready before events can fire, after the document all DOM elements have loaded which you can be sure of, otherwise you're looking for an event which hasnt laoded into the DOM

Without the $(document).ready(), the first has not actually been bound to $('.topCart').
The second example, using the document ready gives a moment or time at which to bind the function to the hover event.

Multiple Jquery events on one page

I am quite new to Jquery and need help trying to get a few events to run on the same page. I have two sections of events, one is a .get which passes data to a file and then displays retrieved data, this happens on page load. The second section is on click events which send and receive data when a button is clicked.
These events all work as needed, but if I have both sections on one page the on click events do not work. Below is the code I have and I hope someone knows how to get them all to work? Thanks
<script type="text/javascript">
$.get("/layout/standard/check.php", { url: "domain"}, function(data){
$("#content-area").html(data)
});
$(".discuss").click( function() {
$.post('/layout/standard/report-action.php', {form: "discuss"},function(data){
$(".message").html(data);
$(".message").show("slow");
});
});
$(".request").click( function() {
$.post('/layout/standard/report-action.php', {form: "request"},function(data){
$(".message").html(data);
$(".message").show("slow");
});
});
$(".report").click( function() {
$.post('/layout/standard/report-action.php', {form: "report"},function(data){
$(".message").html(data);
$(".message").show("slow");
});
});
</script>
I believe that I have found why it's not working, the onclick links are put on the page by the get event. It would appear that the buttons work if they're already on the page but not if they are inserted this way.
This doesn't make sense to me as the buttons are still acting as links with no problem...

Try delegation.. and putting your code inside a document.ready function
$(function() {
$.get("/layout/standard/check.php", {
url: "domain"
}, function(data) {
$("#content-area").html(data)
});
$("body").on('click','.discuss,.request,.report',function() {
$.post('/layout/standard/report-action.php', {
form: $(this).attr('class') //this is assuming you only have 1 class per element
}, function(data) {
$(".message").html(data);
$(".message").show("slow");
});
});
});​

You might need to delegate the events if they are attached to content created dynamically. Try replacing:
$(".discuss").click( function() {
With:
$('body').on('click', '.discuss', function() {
And continue for all your events. You can replace the 'body' selector with another selector as long as it is always present in your document.
