jQuery get an element by its data-id
提问by MacSalty
Similar to this question here, I'm looking to get an element based on it's data-id.
类似于这里的这个问题，我希望根据它的数据 ID 获取一个元素。
<a href="#" class="whatever" data-item-id="stand-out">...</a>
<a href="#" class="whatever" data-item-id="stand-out">...</a>
I'm looking to take action on the a tag. It has a shared class amongst many other elements and has no base id, just a data-item-id.
我希望对 a 标签采取行动。它在许多其他元素中有一个共享类，并且没有基本 id，只有一个数据项 id。
Can the element be found by it's data-item-id or can I only find out what the data-item-id is?
元素可以通过它的数据项 ID 找到还是我只能找出数据项 ID 是什么？

$('[data-item-id="stand-out"]')
$('[data-item-id="stand-out"]')

You can always use an attribute selector. The selector itself would look something like:
您始终可以使用属性选择器。选择器本身看起来像：
a[data-item-id=stand-out]

Yes, you can find out element by data attribute.
是的，您可以通过数据属性找出元素。
element = $('a[data-item-id="stand-out"]');
