javascript - jQuery 如何获取 td 单元格值

Question

当用户单击行上的任意位置时，我试图获取发票编号的值

下面是我的表格

<div class="panel ui-widget-content" id="invoiceList">
<h2 class="ui-widget-header ui-corner-top" style="cursor: pointer; "><span>Invoices</span></h2>
    <table cellspacing='0' id='header' class="ui-widget">
        <tr>
            <th>Invoice Number</th>
             <th>Invoice Total</th>
        </tr>     
        <tr>
            <td><a href="#"  >INV-Error_Test1</a></td>
            <td>22.000000 USD</td>
        </tr>
        <tr>
            <td><a href="#"  >INV-Error_Test2</a></td>
           <td>22.000000 USD</td>
        </tr>
    </table> 
</div>

下面是我的 jQuery，仅当单击发票号码字段时才提供发票号码

$("#invoiceList td").click(function (e) {
var result = $(this).text();
console.log('invoice --->'+result);
});

当用户点击该行的任意位置时，有人可以帮我获取发票号码吗？

检查一下，这可能是一个解决方案:

$('tbody tr').on('click', function(e){
   var value = $(this).find('td:first-child a').text();
  alert(value);
  e.stopPropagation();
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div class="panel ui-widget-content" id="invoiceList">
<h2 class="ui-widget-header ui-corner-top" style="cursor: pointer; "><span>Invoices</span></h2>
    <table cellspacing='0' id='header' class="ui-widget">
      <thead>
        <tr>
            <th>Invoice Number</th>
             <th>Invoice Total</th>
        </tr>
        </thead>
      <tbody>
        <tr>
            <td><a href="#"  >INV-Error_Test1</a></td>
            <td>22.000000 USD</td>
        </tr>
        <tr>
            <td><a href="#"  >INV-Error_Test2</a></td>
           <td>22.000000 USD</td>
        </tr>
        </tbody>
    </table> 
</div>
