jQuery通过其data-id获取一个元素

Question

Similar to this question here , I'm looking to get an element based on it's data-id.

<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.

Can the element be found by it's data-item-id or can I only find out what the data-item-id is?

Answer 1

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

Answer 2

You can always use an attribute selector . The selector itself would look something like:

a[data-item-id=stand-out]

Answer 3

This worked for me, in my case I had a button with a data-id attribute:

$("a").data("item-id");

Fiddle

Answer 4

是的，您可以通过数据属性找出元素。

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