電子郵件重新鍵入警報jquery

Question

如果用戶沒有在第二個電子郵件輸入表單上鍵入確切的電子郵件地址，如何做一個簡單的警報與jQuery彈出？這裏是我迄今爲止

  <div id="reservation-request"> 

       <form method="post" action="test.php"> 
        <tr>  
         <td> Email</td> 
         <td> 
          <input type="text" name="Email" id="Email" /> 
         </td> 
        </tr> 
        <tr>  
         <td>re-type Email</td> 
         <td> 
          <input type="text" name="Email2" id="Email2" /> 
         </td> 
        </tr> 

        <tr> 
         <td colspan="2" align="right"> 
          <input type="image" src="images/submit.jpg"> 
         </td> 
        </tr> 
       </form> 
      </div> 

Answer 1

var a=$('#Email2').val(); 

var b=$('#Email1').val(); 
if(a!=b){ 
alert('email 1 and email 2 are different !') 
}; 

Answer 2

你需要這樣的事情。

給你的提交按鈕的ID，像submit

$('#submit').click(function(){ 
    var e1 = $('#Email').val(); 
    var e2 = $('#Email2').val(); 

    if(e1 != e2){ 
     alert('Your emails don\'t match!!'); 
     return false 
    } 
});
