jQuery code snippet to get class list of an element. We are using jQuery attr("class") to get the class list as string and then splitting it on space.
<script src="//ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script>
<div id="id1" class="class1 class2 class3">text inside div</div>
<pre id="msg"></pre>
<script type="text/javascript">
var classes = $("#id1").attr("class");
var classes_arr = classes.split(" ");
$("#msg").text("div classes: " + JSON.stringify(classes_arr));
</script>
