jQuery ajax jsonp调用始终会出现意外的令牌错误

Question

I've been wasting a great deal of time for something I think is so simple, yet there are no good examples that illustrate how and what the ajax call is doing.

This is my javascript code:

$.ajax({
type: 'GET',
url: 'https://maps.googleapis.com/maps/api/timezone/json',
dataType: 'jsonp',
data: {
    location: myLoc,
    timestamp: myTime,
    sensor: true
},
success: function(){alert('OK');},
error: function(){alert('FAIL');}
})
}

The variables "myLoc" and "myTime" are not the problem. In fact if I cut and paste the URI into my browser it works just fine and shows the data: https://maps.googleapis.com/maps/api/timezone/json?callback=jQuery18307430207263678312_1354817349576&location=36.7468422%2C-119.7725868&timestamp=1354817353&sensor=true&_=1354817353398

From what i've been reading, the "callback" parameter is automagically generated and somehow the code should be smart enough to call the success function or error function.

The error that chrome returns is "Uncaught syntax error unexpected token ':'" The javascript code always calls the error function no matter what I try. I added a jsonpCallback parameter (didn't work), json parameter (didn't work), changed dataType to "json" (didn't work due to cross domain error).

Please help.

$.ajax({
    type: 'GET',
    url: 'https://maps.googleapis.com/maps/api/timezone/json',
    dataType: 'jsonp',
    contentType: 'application/json; charset=utf-8',
    data: JSON.Stringify({
        location: myLoc,
        timestamp: myTime,
        sensor: true
    }),
    success: function(){alert('OK');},
    error: function(){alert('FAIL');}
});
