我正在尝试仅在第二列上单击事件并在第三列按钮上单击事件,但事件未触发.

HTML:

<table class="table table-bordered table-hover">
      <tr>
        <td class="webIcon">
        <img src="Img/icon.png"></img>
        </td>
        <td class="tabTitle tabRow">Smith</td> 
        <td class="closeTab">
            <button type="button" class="btn btn-default btn-sm " aria-label="Left Align">
                <span class="glyphicon glyphicon-remove" aria-hidden="true"></span>
            </button>
        </td>
      </tr>
</table>

jQuery的:

 $( '.table tr:nth-child(2)').delegate("td","click",function(){
            $('.tabRow').click(function(){
                var id = $(this).parents('tr').attr('id');
                console.log(id);
            });
        });

  $( '.table tr:nth-child(3)').delegate("td","click",function(){
            $('.button').click(function(){
                var id = $(this).parents('tr').attr('id');
                console.log(id);
            });
        });
