This is a bit of a hack, but you are client side so 🙂

This code makes some assumptions – like that the script tage for myscript.js exists

Assume you have some markup on your page like so:\

<script src='../js/myscript.js' type="text/javascript"></script>
<div>hiya</div>

OK, now we will use the script tag and get the base url from that 🙂

Let’s create a Util class we can use, add a get base url method and alert that value:

Working copy here: http://jsfiddle.net/SmCLy/

function Util() { /*...Nothing...*/
}

Util.getBaseURL = function() {
    //<summary>
    //    Returns the application base URL (well, a URL that is
    //    equivalent to such - it may have some "backtracking", 
    //    i.e. "../" at
    //    the end of the URL to simulate the root...)
    //</summary>    
    // 1) Find the script include for this JavaScript file:
    var scriptElements = document.getElementsByTagName("script"),
        getScriptPathFragmentPosition = Util.getBaseURL._getScriptPathFragmentPosition,
        getScriptPathFragmentPositionResult = getScriptPathFragmentPosition(scriptElements, "js/myscript.js"),
        posScriptPathFragment = getScriptPathFragmentPositionResult.posScriptPathFragment;

    // 2) Create the "base" URL by taking the current URL,
    // stripping the page from the end, and appending
    // sufficient "../" sequences to
    // construct the equivalent of the application's root URL:
    var scriptElementSrcLower = getScriptPathFragmentPositionResult.scriptElementSrcLower;
    var backPathToRoot = ((scriptElementSrcLower !== "") ? scriptElementSrcLower.substring(0, posScriptPathFragment) : "");
    var currentPath = location.href;
    var currentPathWithoutPage;
    var PAGE_TOKEN = ".aspx";
    var posPageToken = currentPath.toLowerCase().indexOf(PAGE_TOKEN);
    if (posPageToken > -1) {
        var trimmedPath = currentPath.substring(0, posPageToken + PAGE_TOKEN.length);
        currentPathWithoutPage = trimmedPath.substring(0, trimmedPath.lastIndexOf("/") + 1);
    } else {
        currentPathWithoutPage = currentPath.substring(0, currentPath.lastIndexOf("/") + 1);
    }
    return (currentPathWithoutPage + backPathToRoot);
};

Util.getBaseURL._getScriptPathFragmentPosition = function(scriptElements, scriptPathFragment) {
    var scriptElementsIndex = (scriptElements.length - 1),
        scriptElementSrc = "",
        scriptElementSrcLower = "",
        posScriptPathFragment = -1;

    while (scriptElementsIndex >= 0) {
        scriptElementSrc = scriptElements[scriptElementsIndex].getAttribute("src");
        if (typeof(scriptElementSrc) != "undefined" && scriptElementSrc !== null && scriptElementSrc !== "") {
            scriptElementSrcLower = scriptElementSrc.toLowerCase();
            posScriptPathFragment = scriptElementSrcLower.indexOf(scriptPathFragment);

            if (posScriptPathFragment >= 0) {
                break;
            }
        }

        scriptElementsIndex--;
    }

    var result = {
        posScriptPathFragment: posScriptPathFragment,
        scriptElementSrcLower: scriptElementSrcLower
    };

    return result;
};

alert(Util.getBaseURL());

SO, on your page you could do:

var myajaxUrl = getBaseURL()+"MyPage/GetDetails";
