.click() jQuery function works for one ID but not variable

I have this code in my js file and basically what I want to test out is, if the user clicks on a certain button (which has ID of admin).
I want it to bring up a closeButton which is png image and then when the user clicks this again it should disappear. To test of the button functions are responsive I have put alerts in the functions.
Clicking on the initial button works, the function finds the corresponding ID, makes the alert("jQuery Worked") line and brings up the closeButton image.
However when I click on the close button nothing happens (we expect here that the alert("hiii") would work but it doesn't. I have looked online and found that my code needed to be in a $(document).ready(function() {} function which it is but it isn't working. I also tried to use the ID of the image to make the closeButton image disappear but that didn't work either. So I have tried just using the $closeButton variable which I thought for usre should work but doesn't. Why?
.js file
var $closeButton = $("<img>");
$(document).ready(function() {
$("#admin").click(function (event) {
var $overlay = $("<div id='overlay'> </div>");
var $closeButton = $("<img class='classMe' id='closeButtonID' src='https://s23.postimg.org/ouup1ib6z/close_button.png'></img>");
$("body").append($overlay);
$overlay.append($closeButton);
alert("jQuery worked");
});
$closeButton.click(function() {
alert("hiiii");
});
});

you looking for Event delegation.
Event delegation refers to the process of using event propagation
(bubbling) to handle events at a higher level in the DOM than the
element on which the event originated. It allows us to attach a single
event listener for elements that exist now or in the future. Inside
the Event Handling Function.
$(document).on('click', '#closeButtonID', function() {
alert('hiii');
});

Do this:
$(document).ready(function() {
$("#admin").click(function (event) {
var $overlay = $("<div id='overlay'></div>");
var $closeButton = $("<img id='closeButtonID' src='https://s23.postimg.org/ouup1ib6z/close_button.png'></img>");
$("body").append($overlay);
$overlay.append($closeButton);
alert("jQuery worked");
});
$(document).on('click', '#closeButtonID', function() {
alert('hi');
});
});

Not a good way to do this but it's a different way to solve the problem , Hope it will help you :
var $closeButton = $("<img>");
$(document).ready(function() {
$("#admin").click(function (event) {
var $overlay = $("<div id='overlay'> </div>");
var $closeButton = $("<img class='classMe' id='closeButtonID' src='https://s23.postimg.org/ouup1ib6z/close_button.png'></img>");
$("body").append($overlay);
$overlay.append($closeButton);
alert("jQuery worked");
close();
});
function close(){
$('#closeButtonID').click(function() {
alert("hiiii");
});
}
});

click event not working when changing id or class

I'm starting with jquery, and have an issue here:
http://jsfiddle.net/8guzD/
$('#test.off').click(function(){
$(this).removeClass('off').addClass('on');
});
$('#test.on').click(function(){
$(this).removeClass('on').addClass('off');
alert('ok');
});
the first part of the code goes well, the class is apply, but when I attach an event in this element with its new class it won't work.
Can someone explain me what is the problem exactly?
I tried with javascript,
http://jsfiddle.net/R5NRz/
var element = document.getElementById('test');
element.addEventListener('click', function() {
this.id ='test2';
alert("ok");
}, false);
var element2 = document.getElementById('test2');
element2.addEventListener('click', function() {
alert("ok2");
}, false);
and it didn't really help me, having the same issue

try
$(document).on("click",'#test.on',function(){
$(this).removeClass('off').addClass('on');
alert('ok');
});
$(document).on("click",'#test.off',function(){
$(this).removeClass('off').addClass('on');
alert('ok passs');
});
Demo

In your jQuery example you are binding to DOM elements that exist at that time. That is why you see the first fire but not the second. It is not a match for your '#test.on' selector when the code is run. What you want to do instead is use delegation:
$('#test').on('click',function() {
var ele = $(this);
if (ele.hasClass('on')) {
ele.removeClass('on').addClass('off');
} else {
ele.removeClass('off').addClass('on');
}
});
This assumes that you are doing more than just toggling classes. If you want simply toggle classes then an easier solution is to pick one as the default and use the other as a flag. For example, .on is on but without .on it's off. Then you can just use toggle:
$('#test').on('click', function() {
$(this).toggleClass('on');
});

$("#test.on")
Doesn't bind to anything. Try this:
$('#test').click(function() {
if($(this)).hasClass('off') $(this).removeClass('off').addClass('on');
else $(this).removeClass('on').addClass('off');
});
You might consider using an 'active' class instead and just toggling that, instead of have two separate on/off classes. Then you can write:
$("#test").click(function() {
$(this).toggleClass('active');
});

Issue using added class with jQuery

I wrote an inline script to automatically handle when a browser can not load an SVG and replace it with a PNG image. This part works great, however I also want to change the image onhover and this answer worked great for me except that I don't need it to "run and find" if the browser can handle SVG and doesn't use the PNGs. So, I thought I would have it trigger when a class of noSVG (herein referred to as "myclass") was added to the IMG tags.
Now here's were the issues start, I can use CSS to modify the style of the class which is added. But I can't use jQuery to modify it. Even stranger, when I went to add it to JSFiddle for you guys, it works. Before you guys think that I'm using a bad version of jQuery I tested multiple versions (including 1.10.1 which is use by JSFiddle).
HTML:
<img src="1.svg" onerror="this.onerror=null; this.src='1.png'; this.className+=' myclass';" class="image" id="1" />
jQuery:
$(function() {
$(".myclass")
.mouseover(function() {
var src = $(this).attr("src").match(/[^\.]+/) + "hover.png";
$(this).attr("src", src);
//console.log("moused over");
})
.mouseout(function() {
var src = $(this).attr("src").replace("hover.png", ".png");
$(this).attr("src", src);
//console.log("moused out");
});
});
JSFiddle

You are adding the class myclass dynamically to the image, so you need to use event delegation
$(function () {
$(document).on('mouseover', ".myclass", function () {
var src = $(this).attr("src").replace('.png', 'hover.png');
$(this).attr("src", src);
//console.log("moused over");
}).on('mouseout', ".myclass", function () {
var src = $(this).attr("src").replace("hover.png", ".png");
$(this).attr("src", src);
//console.log("moused out");
});
});

Disable CSS link for 1 second after it has been clicked

I'm trying to have a CSS link disabled for 1 second after it has been clicked.
I have tried this without success;
In the header:
<script type="text/javascript">
$(function() {
$("#link").click(function() {
$("#link").attr("disabled", "disabled");
setTimeout(function() {
$("#link").removeAttr("disabled");
}, 2000);
});
});
</script>
Html:
the link text
CSS:
.link:diabled {
some values here.. }

You have a class="link", but with $("#link") you are addressing the id called link.
So write $(".link") everywhere instead of $("#link").
By the way: with .link:disabled you won't address the link as this only works on inputs and buttons. If you need to address it, use .link[disabled="disabled"] { ... } or even better add a class to it called disabled_link and then do in CSS .disabled_link { ... }.

There are quite a few problems here:
You are using # (the ID selector), but your html is using classes.
<a> does not have a disabled attribute
If it did, you would probably want to use .prop instead of .attr
If you change code to use classes, $(".link").prop("disabled", true) would affect all anchors, so you should probably use this.
Because disabled does not exist for <a>, the :disabled selector does not seem to work for CSS.
A working solution would be something like this:
$(".link").click(function() {
var $this = $(this);
$this.addClass('disabled');
setTimeout(function() {
$this.removeClass('disabled');
}, 2000);
});
$(document).on('click', '.disabled', function (e) {
e.preventDefault();
});
http://jsfiddle.net/ExplosionPIlls/PaYcc/

'link' is a class and you are using it as ID. Do $('.link') instead of $('#link').

I think this approach works better. The other allows you to click the link multiple times and mess up the setTimeout this unbinds the event and then re-attaches the event after the setTimeout ex: double click the link
$(".link").click(linkBind);
function linkBind(){
var $this = $(this);
$this.addClass('disabled');
$this.unbind('click');
setTimeout(function() {
$this.removeClass('disabled');
$this.bind('click', linkBind);
}, 2000);
}
$(document).on('click', '.disabled', function (e) {
e.preventDefault();
});

Hack: Disable click click with jQuery

I'm hacking a gallery plugin where I want to disable the click event for the thumbnail and replace it with a hover event.
This is what I did: http://jsbin.com/enezol/3
$(function() {
var galleries = $('.ad-gallery').adGallery();
$('.ad-thumb-list a').hover(function() {
$(this).click();
});
$('.ad-thumb-list a').click(function() {
return false;
});
});
The plugin doesn't allow me to set event to use. So Instead of changing it from their code, I'll just add a little tweak on top of it.
So I want to disable the click event for the 'thumbnail' and just use 'hover' event instead.
Any got and ideas? I'm also open to other approach as long as it meets my requirement.
Thank You!
Trying to implement Steph Skardal and Nicosunshine suggestion:
var thumbs = $('.ad-thumb-list a'),
oldfunction = thumbs.data("events").click["function () { context.showImage(i); context.slideshow.stop(); return false; }"];
thumbs.unbind("click").hover(oldFunction);
edit: My Solution:
I use return false to restrict it from going to the url but it does not restrict in calling the function. Any alternative ideas?
var galleries = $('.ad-gallery').adGallery();
var thumbs = $('.ad-thumb-list a');
thumbs .hover(
function () {
$(this).click();
},
function () {
}
);
thumbs.click( function () { return false; });

You want to use jQuery's unbind method, to unbind the click event. It will have to be called after the plugin is called. E.g.:
$('.ad-thumb-list a').unbind('click');

You could try to unbind the click method and then bind the original function to the hover.
If you can't get the original function you can get it by seeing what the console returns if you throw:
$('.ad-thumb-list a').data("events").click; //name of the property that has the function
then you grab that function and do:
var thumbs = $('.ad-thumb-list a'),
oldfunction = thumbs.data("events").click["theValueYouGotInTheConsole"];
thumbs.unbind("click")
.hover(oldFunction);
Edit:
Here is an example of what I ment with "theValueYouGotInTheConsole", in the image I'm accessing the click property, and then the "4" is where the function is stored.
If you don't want to hardcode the value you can do:
var dataEvents = thumbs.data("events").click,
oldFunction;
for(var functionEvent in dataEvents) {
oldFunction = dataEvents[functionEvent];
break; //I'm assuming there's only one event
}
