javascript - 使用 jquery 在 div 内的 anchor 标记中添加类

Question

有谁知道如何在 A 标记中添加类:

<a href="/souscription/digital-vie">Subscribe</a>

这是我的 html:

<div class="module" id="prod-subscription">
    <div class="entity entity-bean bean-ap-bl-instruct contextual-links-region block container">
        <div class="contextual-links-wrapper contextual-links-processed">
            <a class="contextual-links-trigger" href="#">Configure</a>
            <ul class="contextual-links">
                <li class="bean- first last">
                    <a href="/block/souscription/edit?destination=node/3719"> bloc</a>
                </li>
            </ul>
        </div>    
        <div class="row">
            <div class="col-md-3">
                <h2>simple<span>in 3 </span></h2>
            </div>
            <div class="col-md-6">
                <ol>
                    <li>
                        <span>1</span><p>text</p>
                    </li>
                    <li>
                        <span>2</span><p>texte testx</p>
                    </li>
                    <li>

                    </li>
                </ol>
            </div>
            <div class="col-md-3">
                <a href="/souscription/digital-vie">Subscribe</a>

Answer 1

你可以使用

$('a[href="/souscription/digital-vie"]').addClass('classHere');

或

$('div#prod-subscription a[href="/souscription/digital-vie"]').addClass('classHere');

或

$('a[href="/souscription/digital-vie"]:contains("Subscribe")').addClass('classHere');

$('a[href="/souscription/digital-vie"]:contains("Subscribe")').addClass('classHere');

.classHere{
  background : red;
}
