API works in the browser, not JS

Question

This URL outputs JSON in the browser

http://api.sfpark.org/sfpark/rest/availabilityservice?lat=37.7832776731&long=-122.405537559&radius=0.10&uom=mile&response=json

But when I use it with Jquery like below, it seems to output this error

{"STATUS":"ERROR","MESSAGE":"Error while retrieving availability.  Search parameters are not valid. callback is not a valid request parameter. _ is not a valid request parameter.","RESPONSE_SENT_TS":"2014-08-15T12:16:01.455-07:00","REQUEST_RECD_TS":"2014-08-15T12:16:01.450-07:00"}

And this is the code I'm using

var parkingUrl = "http://api.sfpark.org/sfpark/rest/availabilityservice?lat=37.7832776731&long=-122.405537559&radius=0.10&uom=mile&response=json";

$.ajax({
    url:parkingUrl,
    type:'GET',
    dataType:'JSONP',
    success: function(data){
        console.log(data);
    }
});

According to their API docs, they do in fact support JSONP, you need to add this parameter:

&jsoncallback=callbackFunctionName

To your request url
