Why don’t self-closing script tags work?
I had this bit of javascript code inside a <head> element.
<script src="jquery-1.3.2.js" type="text/javascript" />
<script type="text/javascript">
$(document).ready(function() {
$("#welcome").addClass("centered");
$("#created").addClass("centered");
});
</script>
Which refused to work until I used an explicit end script element:
<script src="jquery-1.3.2.js" type="text/javascript"></script>
Why is there a difference?
EDIT: the entire header was:

I don't understand why the script element needs an explicit end element but the link element doesnt.
Yeah, you always need to end script elements like that. It doesn't support the XHTML format of ' />' to end the tag.
What is the doctype of your document? Technically minimized tags like your first example are an XML-only thing. In most cases HTML allow them, but the correct HTML is your second example.
Certain elements like script and iframe dont work correctly in all browsers unless you have a closing tag, even if there is no content inside. While I agree that this is stupid, its just one more of those inconsistencies that web developers need to be aware of.
I would imagine that once browser vendors implement actual XHTML (so we can send XHMTL as application/xhtml+xml not text/html) that at that point they would also fix inconsistencies like this. Or maybe I'm just an optimist.

I can't get jQuery to work on my page. so I used jsfiddle.net to test if my jQuery code works, and it does. However, when I copy and paste the same code unto my document, it doesn't work. So I'm assuming that there's an error with linking the jQuery external file on my html document. I'm using TextWrangler as my text editor.
html
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title> Rules </title>
<link rel="stylesheet" href="styleRules.css" />
<script type="text/javascript" src="js/jquery-1.10.2.min.js"></script>
<script type= "text/javascript" src="JsRules.js"> </script>
</head>
<div id="left" >
<ol>
<li> First Rule </li>
</ol>
</div>
css
#left {
float:left;
margin-left:200px;
}
jQuery
$(document).ready(function () {
$("#left").mouseenter(function () {
$("#left").fadeTo("fast", 0.25); });
});
Thanks for the time in answering and reading this. I'm currently stuck, I've reached a dead end, and I can't wait to overcome this problem!
I agree with other people that it's most likely a typo in the name of your jQuery file. I created a web page using your exact code except that I spelled the jquery file correctly. It worked fine.
And even though using the BODY element is proper and important, it didn't affect the outcome of my testing your code.
Please, use the "Inspect Element" (tools of chrome ) or Firebug (tool of Firefox and Chrome) for find the error.
Now for me the possible errors are:
Name not declared correctly for example <script type="text/javascript" src="js/jquery-1.10.2.min.js"></script>
you can change the script with external files (libraries of google) <script src="http://code.jquery.com/jquery-2.0.0.js"></script>
Now I create the DEMO on JSFIDDLE with your code and seems that it works
You have a typo in your HTML referencing the jQuery document:
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title> Rules </title>
<link rel="stylesheet" href="styleRules.css" />
<!---Typo was here--->
<script type="text/javascript" src="js/jquery-1.10.2.min.js"></script>
<script type= "text/javascript" src="JsRules.js"> </script>
</head>
<div id="left" >
<ol>
<li> First Rule </li>
</ol>
</div>
</body>
I'm having some problems getting FancyBox to work...I figure its something pretty simple but I'm still a beginner with web design and the process is a little confusing to me right now. This is what I have so far:

$("a.iframe").fancybox();
});
</script>
</head>
<body>
<a class="iframe" href="./iFrameFancy.html">Test FancyBox Here!</a>
</body>
The error I'm getting is pretty popular on SO but I've looked for all the fixes mentioned and nothing has worked yet. This is what I'm getting:
Uncaught TypeError: Object #<Object> has no method 'fancybox'
Any help with this would be greatly appreciated! Thanks all!
You are loading fancybox twice (the normal source one and the packed one). Also remove the dot from your src attributes and make sure the file is where you say it is
So change this
<script type="text/javascript" src="./fancybox/jquery.fancybox.pack-1.3.4.js"></script>
<script type="text/javascript" src="./fancybox/jquery.fancybox.pack-1.3.4.pack.js"></script>
To this
<script type="text/javascript" src="/fancybox/jquery.fancybox.pack-1.3.4.js"></script>
or only this
<script type="text/javascript" src="/fancybox/jquery.fancybox.pack-1.3.4.pack.js"></script>
but not both
Try not including the fancybox js file twice on the same page.
I'm trying to integrate Coin Slider into my page, and I've downloaded and attached the latest Jquery to my header, along with all of the necessary Coin-slider files. However, the page simply stacks the images as if I had simply inserted tags.
The paths for all of the files are correct. I tried following his instructions to the letter on the "how to install" page, with no success. It won't work in IE8, or the latest versions of Chrome or Firefox.

Change your script tags from
<script type="text/javascript" src="js/coin-slider.min.js"></script>
<script type="text/javascript" src="js/coin-slider.js"></script>
<script type="text/javascript" src="js/jquery-1.7.2.js"></script>
to
<script type="text/javascript" src="js/jquery-1.7.2.js"></script>
<script type="text/javascript" src="js/coin-slider.min.js"></script>
coin-slider depends on jQuery therefore it must be loaded before.... And I would suggest you remove js/coin-slider.js as js/coin-slider.min.js and js/coin-slider.js are the same thing ... the .min is just a minified version of the other
The order of your javascript file includes is very important. jQuery should always be first (as is evident in the production documentation). Also, you don't need BOTH coin-slider includes. The .min will be enough:
<script type="text/javascript" src="js/jquery-1.7.2.js"></script>
<script type="text/javascript" src="js/coin-slider.min.js">
This one may sound obvious but the coin-slider package doesn't always come packaged with jQuery, so make sure you have jQuery in your javascript folder before linking too it c(:
it works well
<script type="text/javascript" src="jquery-1.7.2.min.js"></script>
<script type="text/javascript" src="coin-slider.min.js"></script>
<link rel="stylesheet" href="styles.css" type="text/css" />
<link rel="stylesheet" href="coin-slider-styles.css" type="text/css" />

Wordpress is not loading jquery - I think it may have something to do with the fact that it is loading the files absolutely, not relatively, and it won't go to the url (firebug is saying access denied to restricted uri). I have tested vanilla javascript and that works, however as soon as i try to do even the most basic function in $(document).ready(function(){}) it stops working.. is there a way to stop wordpress from appending the website uri to the linked files, and reference them relatively instead, as i think this may fix it.

Wordpress puts jQuery in no-conflict mode which disabled the $() function. Unless you disable no-conflict mode in jQuery you'll have to use jQuery() instead of $().
Try this:
Full answer for those who are facing same problem
You can wrap your javascript inside a self-invoking function, then pass jQuery as an argument to it, using $ as the local variable name. For example:
(function($) {
$(document).ready(function(){
alert('test');
});
}(jQuery));
The jQuery library included with WordPress is set to the noConflict() mode. This is to prevent compatibility problems with other JavaScript libraries that WordPress can link.
In the noConflict() mode, the global $ shortcut for jQuery is not available.
I looked at the site and jquery is loading. This:
<script type='text/javascript'>
$(document).ready(function() {
alert('test');
});
</script>
wont work because WordPress uses jquery in no conflict mode. This:
jQuery(document).ready(function($){
alert('test');
});
is how it should be called in no conflict mode. Also the lightbox plugin is throwing an error:

I have two scripts: lightbox and rss. Lightbox script works very well in mywebform1 but rss feed doesn't work. How can I solve that?
PS: on the other hand, my another webpage(mywebform2) in the same website has only rss feed and works very well.
You are likely experiencing conflict between the jQuery and Prototype frameworks you loaded.
Either choose which one you want to use (arguably the better solution), or consult this documentation for how to use both together.
http://docs.jquery.com/Using_jQuery_with_Other_Libraries
You're probably running into issues because you're using both Prototype and jQuery on the same page. It's highly unlikely that this is the best thing to do. I'd recommend just using jQuery and getting rid of Prototype and Scriptaculous ... there are plenty of ways to get what you need done in jQuery alone.
