我想获得一个具有指定标签名称的元素的父级。
示例代码：
<table>
<tr>
<td>
<input type='button' id='myId' />
</td>
</tr>
</table>
现在我想要这样的东西：
$('#myId').specificParent('table'); //returns NEAREST parent of myId Element which table is it's tagname.
解决方法
见
.closest()：
Get the first ancestor element that matches the selector,beginning at the current element and progressing up through the DOM tree.
也就是说，
$('#myId').closest('table')
(Demo)
