id should be unique use class instead. id应该是唯一的使用class 。 You can use next() to select element immediately after clicked element 您可以在单击元素之后立即使用next()选择元素

 $(document).ready(function() { $(".post-vote-top").click(function() { $(this).next(".post-vote-middle").text(function(i, v) { return parseInt(v, 10)+1; }); }); });

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script> <table> <tr> <td id='post-nomor'>$no.</td> <td id='post-vote' align='center'> <div class='main'> <div class='post-vote-top'>up</div> <div class='post-vote-middle'>1</div> <div class='post-vote-bottom'></div> </div> </td> <td></td> </tr> <tr> <td id='post-nomor'>$no.</td> <td id='post-vote' align='center'> <div class='main'> <div class='post-vote-top'>up</div> <div class='post-vote-middle'>1</div> <div class='post-vote-bottom'></div> </div> </td> <td></td> </tr> </table>
