SharePoint Site Relative CEWP Included Script

This post is about injecting site relative JavaScript include files in SharePoint using CEWP. It is not about injecting JavaScript files using the server-side ASP.NET script manager or any other server-side mechanism.

We all know that the src attribute of the <script> element is either page relative or server relative; or God forbid, absolute. You cannot use the tilde (~) to make the URL site relative, but you can achieve this using the SharePoint page L_Menu_BaseUrl variable and inject the include file into the page dynamically:

<script type="text/javascript">
document.write('<script',
' src="' + L_Menu_BaseUrl +'/ScriptLibrary/SiteSpecificScript.js"',

' type="text/javascript"><\/script>');
</script>

This actually makes the include file URL server relative, but without hardcoding the site path into the URL - making it equivalent to being site relative.

This should work:
src="/ScriptLibrary/jquery-1.3.2.min.js"

Or maybe I misunderstood, and you were talking about linking to a script within the site. In this case I wouldn't use jQuery as an example, as this is typically a script that you want to put in a central location and share across sites...

Yes, you're right, I'll change the example to a site specific script.

This posting is just a sidebar to another post, where I recommend storing the jQuery library in a central place such as the top site of the root site-collection.

Christophe's solution is probably only for toy sharepoint farms with a single site collection.

The post is about generating a path to a library in the current site collection (on a real, production farm with multiple site collections), without hardcoding in the site collection url.

Only if the js variable is still defined, alas most front end code has changed
