HTML Preparation code:

<script src="//ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.slim.min.js"></script>
<div id="foo" class="foo2"></div>

Tests:

getElementById()
var el = document.getElementById("foo"); var className = el.className;
getElementsByClassName()
var el = document.getElementsByClassName("foo2"); var className = el.className;
getElementsByTagName()
var el = document.getElementsByTagName("div")[0]; var className = el.className;
querySelector(#id)
var el = document.querySelector('#foo'); var className = el.className;
querySelector(.id)
var el = document.querySelector('.foo2'); var className = el.className;
querySelectorAll(tag#id)
var el = document.querySelectorAll('div#foo'); var className = el.className;
querySelectorAll(.id)
var el = document.querySelectorAll('.foo2'); var className = el.className;
jQuery(#id)
var el = $("#foo"); var className = el.className;
jQuery(.id)
var el = $(".foo2"); var className = el.className;
jQuery(tag#id)
var el = $("div#foo"); var className = el.className;
jQuery(tag.id)
var el = $("div.foo2"); var className = el.className;
jQuery + getElementById
var el = $(document.getElementById("foo")); var className = el.className;
jQuery + getElementsByClassName
var el = $(document.getElementsByClassName("foo2")); var className = el.className;
