如何使用CSS选择器获取href文本
[英]How to get href Text using CSS selectors
问题描述
I have the following HTML below from Wikipedia main page at https://www.wikipedia.org/ . 
我在Wikipedia主页上的https://www.wikipedia.org/上具有以下HTML。 I'm trying to get the href text 我正在尝试获取href文本
//en.wikipedia.org/
<div class="central-featured-lang lang1" lang="en">
<a href="//en.wikipedia.org/" title="English — Wikipedia — The Free Encyclopedia" class="link-box">
<strong>English</strong><br>
<em>The Free Encyclopedia</em><br>
<small>5 077 000+ articles</small>
</a>
</div>
I've tried this $$('.central-featured-lang.lang1 a[href$=".org/"]') but I still get the whole output, not just the href text. 我已经试过这个$$('.central-featured-lang.lang1 a[href$=".org/"]')但是我仍然得到了整个输出，而不仅是href文本。
[<a href="//en.wikipedia.org/" title="English — Wikipedia — The Free Encyclopedia" class="link-box">…</a><strong>English</strong><br><em>The Free Encyclopedia</em><br><small>5 077 000+ articles</small></a>]
Any advice is much appreciated. 任何建议深表感谢。

Use DOM Element getAttribute() Method 使用DOM元素的getAttribute（）方法
getAttribute() returns the value of a specified attribute on the element.
var element = document.querySelector('a.link-box'), link = element.getAttribute('href'); alert(link)
<div class="central-featured-lang lang1" lang="en"> <a href="//en.wikipedia.org/" title="English — Wikipedia — The Free Encyclopedia" class="link-box"> <strong>English</strong> <br> <em>The Free Encyclopedia</em> <br> <small>5 077 000+ articles</small> </a> </div>

In Javascript you can use document.querySelector along with href attribute, like this: 在Javascript中，您可以将document.querySelector与href属性一起使用，如下所示：
var url = document.querySelector('.central-featured-lang.lang1 a[href$=".org/"]').href; alert(url);
<div class="central-featured-lang lang1" lang="en"> <a href="//en.wikipedia.org/" title="English — Wikipedia — The Free Encyclopedia" class="link-box"> <strong>English</strong> <br> <em>The Free Encyclopedia</em> <br> <small>5 077 000+ articles</small> </a> </div>

Use the .attr() Method: 使用.attr()方法：
$('.central-featured-lang.lang1 a[href$=".org/"]').attr("href")
var url = $('.central-featured-lang.lang1 a[href$=".org/"]').attr("href"); alert( url );
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="central-featured-lang lang1" lang="en"> <a href="//en.wikipedia.org/" title="English — Wikipedia — The Free Encyclopedia" class="link-box"> <strong>English</strong><br> <em>The Free Encyclopedia</em><br> <small>5 077 000+ articles</small> </a> </div>
