3.jquery ajax調(diào)用

function doClick1() { jQuery.support.cors?=?true; //IE10以下 $.ajax({type: "post",url: "http://xx.com/TestService.asmx/Test",dataType: 'xml',data: { inputStr: 'everyone' },success: function (data) {alert(data); //xml對象},error: function (XMLHttpRequest, textStatus, errorThrown) {console.log(XMLHttpRequest);alert('error:' + errorThrown);}});}
