Absolute path in JavaScript script tag

Question

Is there an absolute path while declaring the tag?

this will resolve if I have a aspx page in a folder (one level) script src="../Scripts/jquery-1.4.1.js" type="text/javascript">

this will resolve if I have a aspx page in a folder (two level) script src="../../Scripts/jquery-1.4.1.js" type="text/javascript">

this will resolve if I have a aspx page in the main root script src="Scripts/jquery-1.4.1.js" type="text/javascript">

Do i really need to create different version for each relative path?

Answer 1

You may want to use a relative path from the domain root instead:

<script src="/Scripts/jquery-1.4.1.js" type="text/javascript">

Answer 2

if you need jquery use can use always one absolute path to google cdn

http://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.min.js

a good topic : what is the different form relative vs absolute paths read in :

Answer 3

I prefer using <base> tag and giving refrence as per that base tag

some thing like: http://www.w3schools.com/tags/tag_base.asp

Answer 4

For ASP.NET MVC use Url.Content("~/Scripts/jquery-1.4.1.js") in your view. The tilde makes your path relative to the application root, which could be a sub-folder if you're running as an IIS virtual application.

If it's WebForms, try Page.ResolveUrl() or VirtualPathUtility.ToAbsolute() in your page.

(As an aside, you might also want to consider loading jQuery from a CDN)

Answer 5

<script src="/Scripts/jquery-1.4.1.js" type="text/javascript">

This one does not work at all in web form. "/" does not represent website root dir.
