Jquery nearest（）和match（）将不起作用

Question

我为此设置了一个jsfiddle：http://jsfiddle.net/zatHH/422/

如果<a>包含“找不到短语”，我试图隐藏父div。

可悲的是，我在那里写的东西不起作用，如果有人能帮助我，我会很感激。

谢谢！

您错误地使用match因为它需要正则表达式，而且您正试图在jQuery对象上使用它。无论如何，jQuery有:contains这将满足您的需求：

 $('#cd_category_0 li a:contains("No phrase found by")').closest('.cd-extendable').hide();

＆＃13;

＆＃13;

$('#cd_category_0 li a:contains("No phrase found by")').closest('.cd-extendable').hide();

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<div class="cd-extendable opened">
    <div class="dropdown">All Categories</div>
    <div class="box">
        <div class="bc" style="display: none;"></div>
        <div class="uls">
            <ul id="cd_category_0">
                <li accesskey="" class="selected"><a href="javascript://">All Categories</a></li>
                <li accesskey=""><span title="Show Subcategories"></span><a href="javascript://">No phrase found by

如果使用：contains（），它应该为您提供所需的输出。

    $("#cd_category_0 li a:contains('No phrase found by')").closest('.cd-extendable').hide();
