获取html5< data-something =" value">的值用jquery [英] get the value of html5 <data-something="value"> with jquery

问题描述

前几天我正在阅读stackoverflow中的答案，我读到，jquery可以获得html5的价值< data-something ='value'> ，当我寻找其他东西时，我读到了这些，所以我只是阅读并且不分析这个。现在我真的需要完成这项任务。

The other day I was reading the answers here in stackoverflow and I read, "jquery can get the value of the html5 <data-something='value'>", I read this when I was looking for something else so I just read and don't analyse this. And now I really need accomplish this task.

问题是：它是否可行或者我只是误解了阅读？

The question is: is it posible or I just misunderstand the reading?

推荐答案

<div id="test" data-key="abcd">hahahah</div>

<script type="text/javascript">
var value = $("#test").data("key");
alert(value); //This will show you "abcd"
</script>

我认为数据不仅适用于HTML5，也适用于HTML4

I think data isn't only for HTML5 but also in HTML4
