ASP.Net AJAX $GetJson function won't get executed

Question

I really don't know why but the function(response)-part won't be executed at all - although the Get Method in my Controller gets called by getJSON.

Script:

$.getJSON(getUrl, {
        BUID: buID,
        AID: aID,
        LID: lID
    }, function (response) {
        $('#Test').text("TEST");
    })
};

Controller:

public JsonResult GetMeasures(int buID) {
        return Json(new { Success = true });
    }

The Text of my span element doesn't get changed into "TEST".

Answer 1

Send correct parameters:

$.getJSON(getUrl, {
        buID: buID
    }, function (response) {
        $('#Test').text("TEST");
    })
};

And then you need to use JsonRequestBehavior.AllowGet with JSON return, Also decorate your function with HttpGet attribute

[HttpGet]
public JsonResult GetMeasures(int buID) {
        return Json(new { Success = true }, JsonRequestBehavior.AllowGet);
}
