要求域名在电子邮件地址jQuery验证 [英] Require Domain on Email Address jQuery Validation

问题描述

我使用以下代码（使用 jQuery验证插件）来验证电子邮件地址：

I'm using the following code (with jQuery Validation Plugin) to validate an email address:

    $(".schedule-tour-form").validate({
        rules: {    
            Email: {
                required: true,
                email: true
            }       
        },
    });

    <input id="email" name="Email" class="email" type="email" placeholder="[e-mail]" />

问题是它仍然允许没有域后缀的电子邮件。例如它验证test @ test
如何需要域后缀？

Problem is it still allows emails without domain suffixes. For example it validates "test@test" How to I require a domain suffix?

推荐答案

官方页面的插件，甚至考虑 test @ test as一个有效的邮件，那么我想这是打算的。您可以按照此处创建一个严格的正则表达式的新规则。

The official page of plugin, even consider test@test as a valid mail, then I suppose that this is intended. You could create a new rules, with a strict regex pattern, as suggested here.

//custom validation rule
$.validator.addMethod("customemail", 
    function(value, element) {
        return /^([a-zA-Z0-9_.-+])+\@(([a-zA-Z0-9-])+.)+([a-zA-Z0-9]{2,4})+$/.test(value);
    }, 
    "Sorry, I've enabled very strict email validation"
);

然后到你的规则添加：

rules: {
                    email: {
                        required:  {
                                depends:function(){
                                    $(this).val($.trim($(this).val()));
                                    return true;
                                }   
                            },
                        customemail: true
                    },
