推荐答案

试试这个代码

        Ext.data.JsonP.request({

                    url: 'http://localhost/SLS.BRND.Services/Service1.asmx/Helloworld',
                    params: { method: 'Helloworld', format: 'json' },
                    success: function (response) {
                        alert('Working!')
                        console.log(response);
                    },
                    failure: function (response) {
                        alert('Not working!')
                        console.log(response);
                    }
               });
