Try this
function GetData() {
var ServiceUrl = "";
var content = '';
$.support.cors = true;
$.ajax({
type: 'GET',
url: ServiceUrl,
async: true,
cache: false,
crossDomain: true,
contentType: "application/json; charset=utf-8",
dataType: 'json',
error: function (xhr, err) {
},
success: function (data) {
}
});
Hope this helps
