Question

I am using

$.ajax({
        url: "http://twitter.com/status/user_timeline/treason.json?count=10&callback=?",

        success: function (data, textStatus, jqXHR) {
                        },
        error: function (jqXHR, textStatus, errorThrown) {
        },
        dataType: "jsonp"
 });

How do I know it is using GET or POST?

Answer 1

By default it is GET

You can override it by specifying the type parameter value.

$.ajax({
         url: "someurl",
         type:"POST"
      });

You can also set it up globally at the $.ajaxSetup method so that all ajax calls use that setting unless Override it.

$.ajaxSetup({
  type: 'POST'
});

So if you do not have an $.ajaxSetup section where you are setting it, The answer for your Question is GET
