如果我理解正确，您想检查输入的密码是否等于password123，对吧？

如果是的话，

<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 != 'password123') {
          valid = false;
          alert("Your Password is wrong");
        }

        if (valid) {
          alert('form submitted'); 
        }
        else {
          document.form.pass.focus();
          return false; 
        }
      }
    </script>
  </head>
  <body>
    <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></td>
        <td><input type="submit" name="sub" value="Submit"></td>
      </tr>
    </form>
  </body>
</html>

只需在代码中添加第二个比较：

if(a==="password123") {
    alert("correct Password");
    return true;
}

的login.html

<html>
  <head>
    <script type="text/javascript">
      function validation() {
        var a = document.form.pass.value;
        if(a=="") {
          alert("Please Enter Your Password");
          document.form.pass.focus();
          return false;
        } else if(a==="password123") {
            alert("correct Password");
            return true;
        }
      }
    </script>
  </head>
  <body>
    <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></td>
        <td><input type="submit" name="sub" value="Submit"></td>
      </tr>
    </form>
  </body>
</html>
