获取具有等于变量的属性的元素的属性 [英] Get an attribute of an element that have an attribute that is equal a variable

问题描述

让我们假设我有这个:

<a href="/index" data-title="Home">LINK</a>
<a href="/page2" data-title="Another Page">LINK</a>

，我必须从a标记获得data-title，该标记的href等于location.pathname.

and I have to get the data-title from the a tag that has a href that is equal to the location.pathname.

我该如何使用jQuery?

How do I do this with jQuery?

推荐答案

使用以下代码:

$('a[href="' + location.href + '"]').attr('data-title')

请参见下面的工作代码示例，但将location.href替换为/index以显示代码片段效果很好:

See working code sample below, but location.href replaced to /index to show that snippet works well:

alert($('a[href="' + '/index' + '"]').attr('data-title'))

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<a href="/index" data-title="Home">LINK</a>
<a href="/page2" data-title="Another Page">LINK</a>
