如何使用jquery访问此属性，给定由此定义的div [英] How to access this attribute using jquery, given a div defined by this

问题描述

我有一个通过这个定义的div。假设它是下面的var div：

I have a div which is defined via a this. Imagine it is the var div below:

<td itemid='desired number'>
  <div>div 1</div>
  <div class="action">div 2</div>
</td>

给定var div，我如何计算包含它的td的itemid属性。注意，我不想要一个直接访问itemid属性的解决方案，它必须包含包含div 2的itemid。

Given the var div how can I work out the itemid attribute of the td which contains it. Note, I do not want a solution which directly accesses the itemid attribute, it has to the itemid which is containing div 2.

var div = $('.action')

。

谢谢。

推荐答案

$ b

Try

var itemidValue = $('.action').parent('td').attr('itemid');
