如何使用jquery-validation插件在我的电子邮件字段中仅允许gmail.com作为域进行验证?

How can I allow only gmail.com as domain in my email field validating using jquery-validation plugin ?

$("#myForm").validate({
rules: {
    myemail: {
        required: true,
        email: true,
    }
}
});

推荐答案

您可以像下面这样接受gmail，请注意，我添加了它来忽略.org和.net，还可以继续调整正则表达式，使其完全符合您的方式想要它.

You can accept gmail like this below, notice I added in for it to ignore .org and .net as well you can keep tweaking your regex to exactly how you want it.

\w*\@(?!org)(?!net)[g][m][a][i][l]

基于Sparky的编辑:案例-大写字母和3个字母的电子邮件名称@ gmail.com

Edit based on Sparky's : CASE -- Uppercase and 3 letter email name @gmail.com

$(document).ready(function () {

jQuery.validator.addMethod('gmail', function (value, element) {
    return this.optional(element) || /^[a-z0-9](\.?[a-z0-9]){3,}@[Gg][Mm][Aa][Ii][Ll]\.com$/i.test(value);
}, "not a valid Gmail email address");

$('#myform').validate({
    rules: {
        field1: {
            required: true,
            gmail: true
        }
    },
    submitHandler: function (form) { // for demo
        alert('valid form');
        return false;
    }
});

});
