Question

I have jquery function which looks like this

    function MonitorLoadStatus(loadId) {
     var url = 'LoadAdmin/GetLoadStatus/' + loadId;
     $.get(url, function (data) {
         if (data != "complete") {                 
             $("img[id =" + loadId + "]").show();
             window.setTimeout(function () {
                 MonitorLoadStatus(loadId);
             }, 1000);

         }
         else {
             $("img[id =" + loadId + "]").hide();
         };
     });
 }

and an MVC method which looks like this

public ActionResult GetLoadStatus(string loadId)
    {
        // check some thing and return stuff
        return Content(currentProgress);
    }

The loadid to the above method is being passed as null from the jquery get method. What exactly am i doing wrong

Make sure you have a route in your Global.asax which has a /{loadId} at the end. I remind you that the default route looks like this:

routes.MapRoute(
    "Default",
    "{controller}/{action}/{id}",
    new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);

meaning that the parameter should be called id in your controller action:

public ActionResult GetLoadStatus(string id)
{
    // check some thing and return stuff
    return Content(currentProgress);
}

If you want to use loadId update your route definitions accordingly.
