这是我的代码：

Answer 1

看起来你正在使用jQuery - 它应该是

$.ajax(...

Answer 2

您可以使用：

jQuery.ajax({ 
    type: "POST",
    url: 'UserWebService.asmx/addDetails',
    data: "{'name':'" + name + "'}",
    contentType: "application/json; charset-utf-8",
    dataType: "json",
    async: false,
    success: function (response) {
        var result = response.d;
        alert(result);
    },
    failure: function (msg) {
        alert(msg);
    }
});
