获得有colspan孩子的行？

Question

如何获取对jQuery中具有colspan的子单元格的所有行(tr)的引用？

<table id="report">
    <tr>
        <th>Lorem ipsum</th>
        <th>Lorem ipsum</th>
        <th>Lorem ipsum</th>
        <th>Lorem ipsum</th>
    </tr>
    <tr>
        <td>Lorem ipsum</td>
        <td>Lorem ipsum</td>
        <td>Lorem ipsum</td>
        <td>Lorem ipsum</td>
    </tr>
    <tr>
        <td colspan="4">
            <!-- Details here -->  
        </td>
    </tr>
    <tr>
        <td>Lorem ipsum</td>
        <td>Lorem ipsum</td>
        <td>Lorem ipsum</td>
        <td>Lorem ipsum</td>
    </tr>
    <tr>
        <td colspan="4">
            <!-- Details here -->  
        </td>
    </tr>
</table>

Answer 1

像这样...

$('#report td[colspan]').parent();

或这个...

$('#report tr:has(td[colspan])');

虽然我更喜欢第一个.
