我一直在开发一个脚本,现在我很难过。我尝试了许多来自 Google 的不同正则表达式,但都没有奏效,这是我的代码:
$(document).ready(function() {
var email_check = /^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,6}$/;
num = 0;
$('#email').focus(function() {
$('#email_check').show();
$(this).keyup(function() {
error = 0;
var email = $('#email').val();
num = num+1;
if(!email_check.test(email)) {
error = 1;
}
if(error == 0) {
$('#email_check').html('O'+num+email+error);
}else if(error == 1) {
$('#email_check').html('X'+num+email+error);
}
});
});
});

Set the case insensitive flag (i):
设置不区分大小写的标志 (i):
var email_check = /^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,6}$/i;

You could skip writing the regex and use the jQuery validation pluginfor this task. There's an example hereof validating an email address.
您可以跳过编写正则表达式并使用jQuery 验证插件来完成此任务。这里有一个例子在这里验证的电子邮件地址。
