我的HTML：

<table>
    <tr>
    <td valign="">
        <div id="imgtag"> 
            <center><div id="uploads3"><?php echo $eq_picPa; ?></div></center>
            <div id="tagbox">
            </div>
        </div>
    </td>
    <td valign="top">
        <div id="taglist"> 
            <span class="tagtitle">List of Tags</span> 
            <ol>
                <li rel="1"><a>jelly</a> (<a class="remove">Remove</a>)</li> 
            </ol> 
        </div> 
    </td>
    </tr>
</table>

我的JS：

    $('#taglist').on('click', 'li a.remove',function(){
    alert('hi');
      id = $(this).parent().attr("rel");
      type = "remove";
      // get all tag on page load
      $.ajax({
        type: "POST", 
        url: "savetag.php", 
        data: {"id": id, "type": type},
        success: function(data){
          viewtag();
        }
      });
    });
