Adding a class to a tag
<p>I want to add a class to my <p></p>

<pre><code>&lt;p class="formField" id="equipmentTypeContent"&gt;some content is here...&lt;/p&gt;
</code></pre>

<p>Here is how I tried to do that but it's not working:</p>

<pre><code>$('#equipmentTypeContent').addClass("singleEquipmentText");
</code></pre>

<p>I don't know if in this case jQuery needs to know what type of element it is (in this case a <p> tag) in addition to the type of tag?  I doubt it, I think it only needs the id of the element you're manipulating right?</p>
