javascript - 从 Jquery 表单发布数据

Question

我有一个简单的 jquery 表单，它获取用户的输入并将数据发布到另一个页面并显示成功消息。但我的问题是数据没有发布到其他页面，而是弹出错误消息。

这是我的 Jquery:

 $(document).ready(function () {
     $("#register").click(function () {
    var name = $("#name").val();
    var email = $("#email").val();
    var password = $("#password").val();
    var cpassword = $("#cpassword").val();
    if (name == '' || email == '' || password == '' || cpassword == '') {
        alert("Please fill all fields...!!!!!!");
    } else if ((password.length) < 8) {
        alert("Password should atleast 8 character in length...!!!!!!");
    } else if (!(password).match(cpassword)) {
        alert("Your passwords don't match. Try again?");
    } else {

            $.ajax({

            type:"POST",
            url: "SignUp.aspx/register",    //trying to post to this url
            data: { firstName: name },

            success: function (msg) {
                alert("Success");        // Success message which should pop up if successful
            },
            error: alert("Failed")       //error message which should pop up if there is an error
        });
    }
});
});

这是signup.aspx页面中的代码(类后面的代码):

         public string register(String firstName)
         {
            return "Success";            
         }

我提供的网址是正确的，没有问题。这里可能存在什么问题？

还有其他方法可以将数据发送到另一个页面吗？

感谢您的宝贵时间

这个

        success: function (msg) {
            alert("Success");        // Success message which should pop up if successful
        },
        error: alert("Failed")       //error message which should pop up if there is an error
    });

应该是:

        success: function (msg) {
            alert("Success");        // Success message which should pop up if successful
        },
        error: function(){alert("Failed")}       //error message which should pop up if there is an error
    });

不过，您可能还会遇到其他错误。
