Ajax to set a variable

Ajax to set a variable

Hi i am using the following ajax call to try and set a value of a variable, then display this in a alert.  When the alert comes up all it says is [object] [Object].

I have successfully used a different function in the tenHsServer.aspx.  This is the first time i have tried to retrieve a value, am I right in thinking I can set a value to a variable like this??

var StatusCheck =  $.ajax({
        type: 'GET',
        url: "http://192.168.0.34:81/tenHsServer/tenHsServer.aspx",
        data: {
            t: "ab",
            f: "DeviceStatus" ,
            d:"C5"
               },
        error: function (request, status, error) {
            alert(request.responseText);
            }

            });
 
            alert (StatusCheck)
 

thanks for any help
