this is because of the Same origin policy . you cannot use ajax to call external sites. if you really want to use, you have to use JSONP . Or you can use serverside proxy for this. means, call external site in the server side and do ajax call to the that webservice. For more details see my answer on following question, $.ajax call working fine in IE8 and Doesn't work in firefox and chrome browsers
