使用jquery在div内的锚标记中添加类

Question

有谁知道如何在A标记中添加类：

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

下面是我的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>
                        <span>3</span><p>and text</p>
                    </li>
                </ol>
            </div>
            <div class="col-md-3">
                <a href="/souscription/digital-vie">Subscribe</a>
            </div>
        </div>
    </div>
</div>

Answer 1

您可以使用

$('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;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

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

​

Answer 2

您可以使用jQuery的filter function并过滤确切文本为'Subscribe‘的链接(如果您有多个包含该确切文本的链接，这可能会导致问题)

​

$('a').filter(function() {
  return $(this).text() === 'Subscribe';
}).addClass('new-class');

.new-class {color:red;}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<a href="/souscription/digital-vie">Subscribe</a>

​

Answer 3

我不确定我是否完全理解这个问题。你只是想给锚点标签一个类吗？这可以像<a class="your_class" href="your_link">Subscribe</a>一样简单地完成
