Question

我正在构建一个用户可以注册的网络应用。我有一个注册表单的jquery验证方法。我需要的是根据我的数据库验证用户名的可用性。我不允许使用php来做这个，所以我需要使用java，一个javabean为那个原因。我怎么能像这样结合jquery和java？我应该使用＆＃34;遥控器＆＃34;来自jquery的命令还是将验证与另一个函数结合起来？如果名称已经存在n数据库我不希望我的表单提交。

CheckAvailability.java（我插入为js，因为它不会保留其格式）

$(document).ready(function () {

    //Validation rules for form
    $("#contact_form").validate({
        // Specify the validation rules
        rules: {
            name: {
                required: true
//                remote: ???
            },

            password: {
                required: true,
                minlength: 5
            },

            confirm: {
                required: true,
                equalto: "#password"
            },

            email: {
                required: true,
                email: true
            }
        },

        // Specify the validation error messages
        messages: {
            name: "Please enter your name",

            password: {
                required: "Please provide a password",
                minlength: "Your password must be at least 5 characters long"
            },

            confirm:{
                equalto: "Passwords are not matching"
            },

            email: "Please enter a valid email address"
        },

        submitHandler: function (form) {
            form.submit();
        }
    });
});
