C# Jquery验证手机号码已存在

用于在提交时验证表单的Jquery代码：

 $("#frmAddEditCustomer").validate({
            rules: {
                //"companyname": "required",
                "txtcustomerid": "required",
                "mobile1": {
                    required: true,
                    digits: true,
                    minlength: 8,
                    remote: {
                        url: "AdminWeb.asmx/HelloWorld",
                        type: "post",
                        data: {
                            mobile1: function () { return $("#mobile1").val(); }
                        }
                    }
                },
                "remark": "required",
                "firstname": "required",
                "email": {
                    required: true,
                    email: true,
                },
                "lastname": "required",

            },
            messages: {
                "txtcustomerid": "CustomerID is required",
                //"companyname": "Company Name is required",
                "mobile1": {
                    required: "Mobile Number is required",
                    digits: "Please enter only digits.",
                    minlength: "Please enter at least 8 digits.",
                    remote: "Mobile number already in use!"
                },
                "email": {
                    required: "Email Address is required",
                    email: "Enter proper Email Address"
                },
                "remark": "Short Note is required",
                "firstname": "First Name is required",
                "lastname": "Last Name is required",
            },
            submitHandler: function (form) {
                if ($("#hidEditID").val() > 0) {
                    EditCustomer();
                }
                else {
                    AddCustomer();
                }
                return false;
            }
        });

URL调用方法：

[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public bool HelloWorld()
{
    return false;
}

我想验证mobile1号码，如果数据库中已经存在，那么它应该显示远程默认的错误消息，我正在传递到false以获取错误，但它不工作。

请帮助我解决此问题。

检查浏览器控制台中的“网络”选项卡，并确保请求是否发送到服务器。我使用调试器检查了呼叫是否发送到服务器。您是否得到正确响应。。我的意思是，控制台中的服务器的状态是200，响应为false？在控制台中，我没有收到任何响应网络选项卡中的请求状态如何？
