Select by next instance of class with jQuery
<p>I'm looking to convert a function that selects by id to select the next instance of a given class. </p>

<p>Here is the code.</p>

<pre><code>function swap3(oldDivId, newDivId) {
var oldDiv = document.getElementById(oldDivId);
var newDiv = document.getElementById(newDivId);
oldDiv.style.display = "none";
newDiv.style.display = "block";
}
</code></pre>
