    copied!<p>I would like to use Jquery to add a class to "li" element that contains a "span" element with a html/val equal to zero.</p> <p>For Example if my code looks like this:</p> <pre><code>&lt;ul&gt; &lt;li&gt;&lt;span&gt;Item 1&lt;/span&gt;&lt;span class="num"&gt;30&lt;/span&gt;&lt;/li&gt; &lt;li&gt;&lt;span&gt;Item 2&lt;/span&gt;&lt;span class="num"&gt;0&lt;/span&gt;&lt;/li&gt; &lt;li&gt;&lt;span&gt;Item 3&lt;/span&gt;&lt;span class="num"&gt;20&lt;/span&gt;&lt;/li&gt; &lt;/ul&gt; </code></pre> <p>I want to change it to the following:</p> <pre><code>&lt;ul&gt; &lt;li&gt;&lt;span&gt;Item 1&lt;/span&gt;&lt;span class="num"&gt;30&lt;/span&gt;&lt;/li&gt; &lt;li class="disabled"&gt;&lt;span&gt;Item 2&lt;/span&gt;&lt;span class="num"&gt;0&lt;/span&gt;&lt;/li&gt; &lt;li&gt;&lt;span&gt;Item 3&lt;/span&gt;&lt;span class="num"&gt;20&lt;/span&gt;&lt;/li&gt; &lt;/ul&gt; </code></pre> <p>In the past I have used code to check elements attribute values, but never their html/val doing something to this effect...</p> <pre><code>$('li').has('span.num').addClass('disabled'); </code></pre> <p>However in this case that would result in:</p> <pre><code>&lt;ul&gt; &lt;li class="disabled"&gt;&lt;span&gt;Item 1&lt;/span&gt;&lt;span class="num"&gt;30&lt;/span&gt;&lt;/li&gt; &lt;li class="disabled"&gt;&lt;span&gt;Item 2&lt;/span&gt;&lt;span class="num"&gt;0&lt;/span&gt;&lt;/li&gt; &lt;li class="disabled"&gt;&lt;span&gt;Item 3&lt;/span&gt;&lt;span class="num"&gt;20&lt;/span&gt;&lt;/li&gt; &lt;/ul&gt; </code></pre> <p>Which is obviously not going work... Thanks</p>
