~/ equivalent in javascript

Question

Any smart way of doing a \"root\" based path referencing in JavaScript, just the way we have ~/ in ASP.NET?

Answer 1

The following function will calculate the root of the currently running application. I use it to locate the absolute location of resources, when called from somewhere deep within the application tree.

    function AppRoot() {
        //
        // Returns the root of the currently running ASP application.
        // in the form: "http://localhost/TRMS40/"
        //
        //   origin: "http://localhost"
        // pathname: "/TRMS40/Test/Test%20EMA.aspx"
        //
        // usage:
        //           window.open( AppRoot() + "CertPlan_Editor.aspx?ID=" + ID);
        //

        var z = window.location.pathname.split('/');

        return window.location.origin + "/" + z[1] + "/";
    }
