                    minlength: 5,
                    //equalTo: "#password",
                },
                secretQuestion: "required",
                secretAnswer: "required",
                emailId: {
                    required: true, 
                    email: true,

在 jQuery插件页面上有对远程方法的非常简单的解释。

按照我给你的建议！为了更好地理解该方法，请以扩展形式使用该方法。

emailId: {
    required: true, 
    email: true,
    remote: {
        url: "checkmail.php", //the url of the page you are querying
        type: "post", //the method you are going to use to send the data
        data: { //the data you are going to send
           email: function() { 
             return $("#email").val(); //send the value of email
           }
        }
    }
},

但是，您的代码应该按原样工作。
