Why is this jQuery click function not working?
JavascriptJqueryOnclickClickOnclicklistenerJavascript Problem Overview
Code:
<script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>
<script type="text/javascript">
$("#clicker").click(function () {
alert("Hello!");
$(".hide_div").hide();
});
</script>
The above code doesn't work. When I click on #clicker, it doesn't alert and and it doesn't hide. I checked the console and I get no errors. I also checked to see if JQuery was loading and indeed it is. So not sure what the issue is. I also did a document ready function with an alert and that worked so not sure what I am doing wrong. Please help. Thanks!

Solution 1 - Javascript
You are supposed to add the javascript code in a $(document).ready(function() {}); block.
i.e.
$(document).ready(function() {
$("#clicker").click(function () {
alert("Hello!");
$(".hide_div").hide();
});
});
As [jQuery documentation][1] states: "A page can't be manipulated safely until the document is "ready." jQuery detects this state of readiness for you. Code included inside $( document ).ready() will only run once the page Document Object Model (DOM) is ready for JavaScript code to execute"

I found the best solution for this problem by using ON with $(document).
$(document).on('click', '#yourid', function() { alert("hello"); });
for id start with see below:
$(document).on('click', 'div[id^="start"]', function() {
alert ('hello'); });
finally after 1 week I not need to add onclick triger. I hope this will help many people

Your code may work without document.ready() just be sure that your script is after the #clicker. Checkout this demo: http://jsbin.com/aPAsaZo/1/
The idea in the ready concept. If you sure that your script is the latest thing in your page or it is after the affected element, it will work.
<!DOCTYPE html>
<html>
<head>
<meta charset=utf-8 />
<title>JS Bin</title>
</head>
<body>
<script src="https://code.jquery.com/jquery-latest.min.js"
type="text/javascript"></script>
<a href="#" id="clicker" value="Click Me!" >Click Me</a>
<script type="text/javascript">
$("#clicker").click(function () {
alert("Hello!");
$(".hide_div").hide();
});
</script>
</body>
</html>
Notice:
In the [tag:jsbin] demo replace http with https there in the code, or use this variant Demo

Try adding $(document).ready(function(){ to the beginning of your script, and then });. Also, does the div have the id in it properly, i.e., as an id, not a class, etc.?
Solution 5 - Javascript
You have to wrap your Javascript-Code with $(document).ready(function(){});Look this JSfiddle.
JS Code:
$(document).ready(function() {
$("#clicker").click(function () {
alert("Hello!");
$(".hide_div").hide();
});
});
Solution 6 - Javascript
Be sure there is nothing on your button (such a div or a trasparent img) that keeps from clicking the button. It sounds stupid, but sometimes we think that jQuery is not working and all that stuffs and the problem is on the positioning of DOM elements.
Solution 7 - Javascript
You can use $(function(){ // code }); which is executed when the document is ready to execute the code inside that block.
$(function(){
$('#clicker').click(function(){
alert('hey');
$('.hide_div').hide();
});
});
Solution 8 - Javascript
Just a quick check, if you are using client-side templating engine such as handlebars, your js will load after document.ready, hence there will be no element to bind the event to, therefore either use onclick handler or use it on the body and check for current target

Proper Browser Reload
Just a quick check as well if you keep your js files separately: make sure to reload your resources properly. Browsers will usually cache files, so just assure that i.e. a former typo is corrected in your loaded resources.
See this answer for permanent cache disabling in Chrome/Chromium. Otherwise you can generally force a full reload with Ctrl+F5 or Shift+F5 as mentioned in this answer.
