Question

提供了包含密码验证的登录页面。我想在此代码中添加电子邮件地址"thisisnotmyrealaddress@gmail.com"吗？

我需要帮助设置我的电子邮件地址

的login.html

<html>
  <head>
    <script type="text/javascript">
      function validation()
      {
        var a = document.form.pass.value;
        var valid = true;       
        if(a=="")
        {
          valid = false;
          alert("Please Enter Your Password");
        }
        else if (a != 'notmyrealpassword') {
          valid = false;
          alert("Your Password is wrong");
        }

        if (valid) {
          alert('form submitted'); 
        }
        else {
          document.form.pass.focus();
          return false; 
        }

    <form name="form" method="post" onsubmit="return validation()" action="class_info.html">
      <tr>
        <td> password:</td>
        <td><input type="text" name="pass"></td>
      </tr>
      <tr>

        <td><input type="submit" name="sub" value="Submit"></td>

Answer 1

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

现在要使用这个

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

Answer 2

在密码字段

之前添加此内容

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

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");}

我尝试了下面给出的编码..它运作顺利..

<html>
  <head>
    <script type="text/javascript">
      function validation()
      {
        var b = document.form.pass.value;
var a = document.form.mail.value;
        var valid = true;       






if(a=="")
        {
          valid = false;
          alert("Please Enter Your email");
        }
        else if (a != '303nishanth@gmail.com') {
          valid = false;
          alert("Your email is wrong");
        }

        if (valid) {

        }
        else {
          document.form.mail.focus();
          return false; 
        }

if(b=="")
        {
          valid = false;
          alert("Please Enter Your password");
        }
        else if (b != 'password123') {
          valid = false;
          alert("Your password is wrong");
        }

        if (valid) {
          alert('Email & password matches'); 
        }
        else {
          document.form.pass.focus();
          return false; 
        }
      }
    </script>
  </head>
  <body>
    <form name="form" method="post" onsubmit="return validation()" action="class_info.html">
      <tr>
        <td> email:</td>
        <td><input type="text" name="mail"></td>
      </tr>
<tr>
        <td> Password:</td>
        <td><input type="password" name="pass"></td>
      </tr>
      <tr>
        <td></td>
        <td><input type="submit" name="sub" value="Submit"></td>
      </tr>
    </form>
  </body>
