Getting absolute path with JavaScript

Question

In some part of my code I have this

while(document.images[local].src != imgV)

So, I refer to the images this way:

vermelhaColocada.src = "imagens/something.gif";

But for some reason, document.images.src refers to the absolute URL path (http://localhost/..../images/something.gif).

This is a problem for me because I have to compare with a variable assigned manually:

var imgV = "http://localhost/..../imagens/something-2.gif";

So if I'm not running localhost (or anything I define on that variable), the web app will not work properly (i have to change everytime I execute the app remotely or something).

So I suppose the solution would be getting the URL absolute path, assign to a variable, and then join with "images/something.gif-2".

So my question is, how can I do that? There's any other solution?

This is what I use on my web page:

JavaScript

function GetSiteRoot()
{
    var rootPath = window.location.protocol + "//" + window.location.host + "/";
    if (window.location.hostname == "localhost")
    {
        var path = window.location.pathname;
        if (path.indexOf("/") == 0)
        {
            path = path.substring(1);
        }
        path = path.split("/", 1);
        if (path != "")
        {
            rootPath = rootPath + path + "/";
        }
    }
    return rootPath;
}

I simply add the desired path/filename to what's returned, and I have a fully resolved URL.
