How can I use runat="server" on a script tag in asp.Net

Question

I don't necessarily need to run it at server, however, I would like to use the ~/js/somefile.js syntax.

Previously, I had just set everything with Absolute paths and set my project to be at the root level. SO, I'd just declare all my stylesheets, background images and javascript files something like /css/somefile.css

However, for this project, it doesn't run as root.

I can't put runat="server" on a script tag.

I can put it on a link tag, though.

This must be a common problem with a few simple answers.

Answer 1

You can use functions inside the path string, though, e.g.

<script type="text/javascript"
        src="<%=Url.Content("~/Scripts/jquery-1.4.2.min.js") %>"></script>

However that's the ASP.NET MVC syntax for local paths - I can't remember the forms version off the top of my head.

Answer 2

What I've always done is use a normal script tag and put the src in <% %> tags, as illustrated here:

<script language="javascript" src='<%=ResolveUrl("~/App_Themes/MainTheme/jquery.js")%>' type='text/javascript'></script>

Answer 3

Taken from dailycoding.com:

<script language="javascript" src="<%=ResolveUrl("~/[PATH]")%>" type="text/javascript"></script> 

Answer 4

You can use the ScriptManager for this:

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