Attaching click event won't work - javascript

I've wanted to attach click event to an object not yet added to the DOM like here.
I've used a code from the answer but nothing happens when I click anything.
Here's my HTML:
<html>
<head>
<script src="resources/js/components/jquery/jquery-3.1.1.min.js"></script>
<script src="file.js"></script>
</head>
<body>
asl;kdfjl
<div id="my-button">sdgdf</div>
</body>
</html>
JavaScripts are in those location and I can see them in Sources tab in Chrome.
My file.js has content exactly copy-pasted from jsfiddle:
$('body').on('click','a',function(e){
e.preventDefault();
createMyButton();
});
createMyButton = function(data) {
$('a').after('<div id="my-button">test</div>');
};
$('body').on('click','#my-button',function (e) {
alert("yeahhhh!!! but this doesn't work for me :(");
});

As your code is in the head tag, you need to use a DOM ready wrapper to ensure your code executes after the DOM has rendered elements.
The jsfiddle doesn't have it because the fiddle is set to run the code onload already.
$(function(){
$('body').on('click','a',function(e){
e.preventDefault();
createMyButton();
});
createMyButton = function(data) {
$('a').after('<div id="my-button">test</div>');
};
$('body').on('click','#my-button',function (e) {
alert("yeahhhh!!! but this doesn't work for me :(");
});
});

Your code working with snippet .Better use with document.ready.Post you js after document.ready .And change the selector document instead of body
$(document).ready(function() {
$(document).on('click', 'a', function(e) {
e.preventDefault();
createMyButton();
});
createMyButton = function(data) {
$('a').after('<div id="my-button">test</div>');
};
$(document).on('click', '#my-button', function(e) {
alert("yeahhhh!!! but this doesn't work for me :(");
});
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
asl;kdfjl
<div id="my-button">sdgdf</div>

How to include a jquery plugin in your code

This may be a really dumb question but I'm having trouble including a jquery plugin in my code.
The plugin I'm referring to is: http://davidlynch.org/projects/maphilight/docs/
I want to mimic something very similar to the following:
http://jsfiddle.net/keith/PVpgK/
But when I copy the code over, I keep getting error messages saying "maphilight is not a function"
How do I use a jquery plugin in my code? Thank you
$(function() {
//using the jquery map highlight plugin:
//http://davidlynch.org/js/maphilight/docs/
//initialize highlight
$('.map').maphilight({strokeColor:'808080',strokeWidth:0,fillColor:'00cd27'});
//hover effect
$('#maplink1').mouseover(function(e) {
$('#map1').mouseover();
}).mouseout(function(e) {
$('#map1').mouseout();
}).click(function(e) { e.preventDefault(); });
// initialize tabbing
$(".tabs area:eq(0)").each(function(){
$(this).addClass("current");
});
$(".tab-content").each(function(){
$(this).children(":not(:first)").hide();
});
//map clicks
$(".tabs area").click(function(){
//This block is what creates highlighting by trigger the "alwaysOn",
var data = $(this).data('maphilight') || {};
data.alwaysOn = !data.alwaysOn;
$(this).data('maphilight', data).trigger('alwaysOn.maphilight');
//there is also "neverOn" in the docs, but not sure how to get it to work
if ($(this).hasClass("current") == false)
{
var thisTarget = $(this).attr("href");
$(this).parents(".tabs").find('area.current').removeClass('current');
$(this).addClass('current');
$(this).parents(".tabs").nextAll(".tab-content").children(":visible").fadeOut(1, function() {
$(thisTarget).fadeIn("fast");
});
}
return false;
});
});
You need to include the link to jquery in your html header.
1) Download jquery from jQuery.com
2) Link to downloaded file in your header
Like so:
<head>
...
<script src="/path/to/jquery-1.11.3.min.js"></script>
...
</head>
As the previous answer. But put them in the bottom of the body tag.
<html>
<head>
</head>
<body>
<script src="../path/to/jquery-1.11.3.min.js"></script>
<script src="http://davidlynch.org/js/maphilight/jquery.maphilight.min.js"></script>
</body>
</html>
you need to add the following to the header of your html code
<script type="text/javascript" src="http://davidlynch.org/js/maphilight/jquery.maphilight.min.js">
</script>

jQuery $this is not working on web page

sorry but i am newbie!!!
i am new to jQuery and i have a problem with jQuery $(this)
i have create a really simple jquery function in jsfiddle and it work but it's not work on website
i have use jquery 1.10.1 in jsfiddle and my code too!
you can see code here :
<html>
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"></script>
<script type="text/javascript">
$(".resumeActu").on('click', function(){
var id = $(this).data('id');
alert("id is = "+id);
});
</script>
</head>
<body>
<div class="resumeActu" data-id="3">click me</div>
</body>
</html>
and this is my code in jsfiddle too: demo
i cant understand why my code work on jsfiddle but it's not work in my page
In your website you need to place your code in a document ready handler. This is not required in jsFiddle as it automatically does it for you.
<script type="text/javascript">
$(function() {
$(".resumeActu").on('click', function(){
var id = $(this).data('id');
alert("id is = "+id);
});
});
</script>
The reason your current code does not work is because it is trying to attach the click handler to the .resumeActu element before it exists in the DOM.
try this
$(document).ready(function () {
$(".resumeActu").on('click', function () {
var id = $(this).data('id');
alert("id is = " + id);
});
});
Load this function after document is ready

Why does this super simple jquery not work?

I'm having hard time getting this snippet to work. I have made a minimal example. You can view it online: http://jsfiddle.net/qnnZe/ where it is working!
test.html
<!DOCTYPE html>
<head>
<title>test</title>
<meta charset="utf-8">
<script src="jquery.min.js"></script>
<script src="test.js"></script>
</head>
<body>
<p>I am going to test right now.</p>
</body>
</html>
test.js
$("p").click(function () {
$(this).hide("slow");
});
However, on my server it does not work. Here is the link to my server: http://techinf.de/sleepytime/test.html
As always, any help appreciated.
Because in jsFiddle your script code is executed after the DOM has loaded (that's the default option, see the dropdown set to "onDomReady"), on your page it's executed before that. It would work if you wrap your code in a ready() handler:
$(function()
{
$("p").click(function () {
$(this).hide("slow");
});
});
You need to wrap your click handler in a document ready function.
Try either:
$(document).ready(function () {
$("p").click(function () {
$(this).hide("slow");
});
});
or
$(function () {
$("p").click(function () {
$(this).hide("slow");
});
});
It will execute before the DOM is ready. Click handlers should be added in any of the normal jQuery "ready" methods, like:
$(function() {
$("p").click(function () {
$(this).hide("slow");
});
});

jquery load() after ajax page is loaded - howto

i have following lines included at the bottom of my index.php:
<script type="text/javascript" language="javascript" src="class/jquery-1.4.3.min.js"> </script>
<script type="text/javascript" language="javascript" src="class/jquery.nivo.slider.pack.js"></script>
<script type='text/javascript' language='javascript'>
$(window).load(function() {
$('#slider').nivoSlider();
});
</script>
problem lies in $(window).load ...
index.php's body is updated onload through ajax call which delivers div#slider upon matching. this makes it nivoSlider() not executing. do you have any trick to make this thing work. i do prefer non-jquery way around it, but at the end of the day anything helps.
many thanks
WEBPAGE IS HERE
Add the call in the callback for the AJAX load.
$('.something').load( 'http://www.example.com/foo', function() {
$(this).find('#slider').nivoSlider();
});
Example using your code (for body):
$(function() { // run on document ready, not window load
$('#content').load( 'page.php?c=2&limit=5', function() {
$(this).find('#slider').nivoSlider();
});
});
For link:
<!-- updates links like so -->
<a class='nav' href='page.php?category=art&limit=5&c=1'>art</a>
// in the same document ready function
$('a.nav').click( function() {
var $link = $(this);
$('#content').load( $link.attr('href'), function() {
$(this).find('#slider').nivoSlider();
$link.addClass('selected'); // instead of setting bg directly to #828282;
});
return false; // to prevent normal link behavior
});
Would you not want to use $(document) rather than $(window)?
$(window).load(function() {
$('#slider').nivoSlider();
});
or shorthand
$(function() {
$('#slider').nivoSlider();
});

JQuery click text in span?

I'm trying to use JQuery to have a method fire when the following code gets clicked:
<div class="content_sub_list">
<img src="/imgs/close-icon.jpg" class="exit_sub_list"/>
hello
</div>
It is not doing anything and my JQuery code looks like this:
$(document).ready(
function()
{
$('#my_accnt').click(
function()
{
$('.content_sub_list').css("display", "block");
$('.content_sub_list').css("margin-left", "4px");
$('.content_sub_list').html('<div class="sub_list_header">My A<img src="/imgs/close-icon.jpg" class="exit_sub_list"/></div><BR />text');
});
$('#my_queue').click(
function()
{
$('.content_sub_list').css("display", "block");
$('.content_sub_list').css("margin-left", "165px");
$('.content_sub_list').html('<div class="sub_list_header">My Q<img src="/imgs/close-icon.jpg" class="exit_sub_list"/></div><BR />text');
});
$('.exit_sub_list').click(
function()
{
alert("hi");
$('.content_sub_list').css("display", "none");
});
});
My header looks like this:
<script src="/js/jquery.js" type="text/javascript"></script>
<script src="/js/mContentBar.js" type="text/javascript"></script>
Other functions work in it except this one? for some reason.
So what am I doing wrong, or how i can get this to work? Thanks
This is working for me. Make sure you have jQuery loaded properly. You can either place jquery.js after your html or wrap your jquery code with a document.ready function.
like
(function() {
$('.exit_sub_list').click(
function() {
alert("hi");
});
});
