how to add javascript to asp.net user control?

Question

I found that even I use ResolveUrl to indicates the path, it still does not work unless I add javascript in the page that user control is embeded in.

<script src="<%= ResolveUrl("~/JS/jquery.js") %>" type="text/javascript"></script>
<script type="text/javascript">
 $(document).ready(function(){
       alert("aaaaa");
});
</script>

Is there a way to add JS into user control directly?

Just to clarify, are we talking about an ASP.NET user control? — Caimen

JavaScript is always available (except when it is disabled). You are loading a JavaScript file, the jQuery library to be more specific. Of course it is not doing anything on its own, you have to tell it what to do. But it is there. — Felix Kling

jquery doesn't do anything until you call it. Just linking to it merely loads the library so you can use it. — DA.

If you're talking about creating UserControl-specific javascript, I know exactly what you're talking about. There's no real easy way to do it (aside from just adding a script tag with your script and/or src), so here's what I do:

Create your user control
Create your js specific to that control in a separate .js file
At the top of your user control, put a big flowerbox type comment that lists all the file dependencies for that control. This includes CSS (maybe you have your css separated out too) and any JS files.
When you drop in a control, get in the habit of opening it up first and taking a look at your dependencies. This will ensure that you drop in the correct files too.

Also, naming your separate JS file the same thing as your User Control helps.

<input type="checkbox" onclick="alert('you clicked me!') />

is one tiny sample. Beyond that, we'd need details of what you mean by "control".
