3 个解决方案

#1

add this before passsword field

在密码字段之前添加此内容

 <td>Email</td>
  <td><input type="text" id="email"></td>

In javascript add the following code

在javascript中添加以下代码

 var b = document.getElementById('email').value;
    var validate=/^[A-Za-z0-9#]{0,50}\@[A-Za-z]{0,10}\.[a-z]{0,3}$/g;
    if(b!='')
     {
      if(!validate.test(b)){
      alert("Enter the Valid Email");
      return false;
     }
     }else{alert ("Enter Email");}

#2

 function validateEmail($email) {
   var emailReg = /^([\w-\.]+@([\w-]+\.)+[\w-]{2,4})?$/;
   return emailReg.test( $email );
 }

and now to use this

现在要用它

if( !validateEmail(emailaddress)) { /* do stuff here */ }
