Question

I want to use jQuery to make a simple call to my MVC controller. I was able to debug the server side, meaning the controller picked up the ajax call and return the information requested. But the client side is never updated after server side returns. When I use FireBug to debug the script, the client side is stuck on event.isImmediatePropagationStopped() in handle() of jquery-1.4.1.js. Does that mean the client side simply didn’t get called back? Please help.

$('#ToZip').blur(function() {
    $.getJSON('http://localhost:3958/home/GetZipInfo?id=' + this.value,
        function(result){
            $("#ToCity").val = result.City;
            $("#ToState").val = result.State;
        }
    )
});

public ActionResult GetZipInfo(string id)
{
    // some code to prepare return value, zip
    return Json(zip, JsonRequestBehavior.AllowGet);
}

Thanks in advance

Have you validated your json response? http://api.jquery.com/jQuery.getJSON/ states:

As of jQuery 1.4, if the JSON file
contains a syntax error, the request
will usually fail silently.

Open you handler directly in a browser, and copy and paste it in here:
