I'm trying to add a script reference to jQuery in my master page so that it will work for any page. It currently looks like this

<script type="text/javascript" src="jquery.js"></script>

The problem is that the path is always relative to the executing aspx page so this will only work if the "jquery.js" file is located in the same folder. To make it work I have to change the line to:

<script type="text/javascript" src="../../jquery.js"></script>

This is obviously less than ideal because it will only work for pages that are two levels deep from the root folder. If I try the following, IIS throws an error about an unexpected character.

<script runat="server" type="text/javascript" src="~/jquery.js"></script>

Any ideas?

EDIT: I forgot to mention as well that the script MUST be in the head tag

The current top answer throws a "ASP.NET Ajax client-side framework failed to load." error when I add it to my master page. Its thrown from javascript and not the .Net compiler. If I move the ScriptManager to the head section where it should be I get a compile error about the ScriptManager needing to be inside a form tag.

The third answer throws a "Illegal characters in path." exception from the compiler

EDIT 2: When I add that line to my head tag I get this error from IIS.

The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>)

SOLVED: I took the edited response from the answer below and put it inside an asp:ContentPlaceHolder element

<script type="text/javascript" src="/full/path/to/jquery.js"></script>

Try:

<asp:ScriptManager ID="ScriptManager1" runat="server">
    <Scripts>
        <asp:ScriptReference Path="~/jquery.js" />
    </Scripts>
</asp:ScriptManager>

EDIT:

If you REALLY need this in your <head> section, you could do something like:

<script type="text/javascript" src="<%= Page.ResolveClientUrl("~/jquery.js") %>"></script>

Aye, this is a highly recommended method in a lot of ASP.NET books I've written when dealing with paths in masterpages.

Check "Edit 2" of my original post. Thanks for your help BTW

FYI, my co-worker and I just tried this out. This doesn't seem to work in a nested master page scenario *in the parent master page*. Moving it to the child master page, however, did the trick.

If this script tag goes directly to the browser, then you unlikely can substitute your site's root there. At least not on the server. So you can:

  1. Deploy site to the root of domain name and use absolute paths (simplest solution).
  2. Insert this link with server control.
  3. Preprocess resulting HTML before sending it to the client (with HttpResponse.Filter).

If you're not going to us asp:ScriptManager or absolute paths then you can do it like this:

<script runat="server" type="text/javascript" 
  src='<%= Page.ResolveUrl("~/jquery.js") %>'></script>

You can also use <base> HTML tag:

<base href="http://www.domain.com"&gt;&lt;/base&gt;

and then all the links in header section are relative to base address:

<script type="text/javascript" src="scripts/jquery.js"></script>

It's often useful when you have multiple publishing destinations, like local dev web server, demo server, etc. You just replace that base URL.

I do not know whether you guys found the solution to your problem or not. I was facing the same problem and going nuts to figure out why do I get "jQuery is undefined" error on the plugins i use. I tried all the solutions i get from the internet but no luck at all.

But, suddenly something splash on my mind that may be the script files should be in order. So, I moved the jquery referece to first position and everything start working like charm.

Remember guys, if you're using any plugins with jquery, make sure you use the folloing order of setting reference to those fiels.

  1. reference to the jquery library
  2. reference to the other subsequent plug-in libraries and so on...

e.g.:

  1. "script src="js/jquery-1.3.2.min.js" type="text/javascript"...
  2. "script src="js/jqDnR.min.js" type="text/javascript"...
  3. "script src="js/jquery.jqpopup.min.js" type="text/javascript"...
  4. "script src="js/jquery.bgiframe.min.js" type="text/javascript"...

Always make sure you must put the jquery reference to first and then the subsequent libraries.

Hope, this solves your problem especially when you use with MasterPages. Its very strange that it works no matter what order you use when you don't use MasterPages but when you do, then it somehow requres the proper order.

Good luck and happy coding,

Thanks for this tip!

You can also make the head tag runat="server" and then use the ~ directive in your script includes. You don't want to make your script blocks runat="server" unless they are meant to be server-side code.

<head runat="server">
  <script src="~/jquery.js" ></script>
</head>
