我试图建立一个注册表单，将只接受.EDU电子邮件地址。 我也想保持AJAX功能我有（使用远程参数） 以确保该电子邮件地址没有被使用过。

我怎样才能做到这一点？

  $。validator.addMethod（EDU-电子邮件，
    函数（值）{
        返回（value.endsWith（）EDU。）;
    }，
    E-mail地址必须结束在埃杜。
）;
 

JavaScript没有一个string.endsWith。你必须添加自己的。

现在加入EDU-邮件的形式输入类。

I'm trying to build a sign-up form that will only accept .EDU e-mail addresses. I also want to keep the AJAX functionality I have (using the "remote" parameter) to ensure that the e-mail address hasn't been used before.

How can I do this?

$.validator.addMethod("edu-email", 
    function(value) {
        return (value.endsWith(".edu"));
    },
    "e-mail address must end in .edu."
);

JavaScript doesn't have a string.endsWith. You'll have to add your own.

Now add "edu-email" to the form input class.
