Tests:

  • getElementById()

     
    var el = document.getElementById('foo');
    var className = el.className;

  • getElementsByClassName()

     
    var el = document.getElementsByClassName('foo2')[0];
    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(#id)

     
    var el = document.querySelectorAll('#foo')[0];
    var className = el.className;

  • querySelectorAll(.id)

     
    var el = document.querySelectorAll('.foo2')[0];
    var className = el.className;

  • jQuery(#id)

     
    var el = $('#foo')[0];
    var className = el.className;

  • jQuery(.id)

     
    var el = $('.foo2')[0];
    var className = el.className;

  • jQuery(tag#id)

     
    var el = $('div#foo')[0];
    var className = el.className;

  • jQuery(tag.id)

     
    var el = $('div.foo2')[0];
    var className = el.className;

  • jQuery + getElementById

     
    var el = $(document.getElementById('foo'))[0];
    var className = el.className;

  • jQuery + getElementsByClassName

     
    var el = $(document.getElementsByClassName('foo2'))[0];
    var className = el.className;

  • jQuery + querySelectorAll

     
    var el = $(document.querySelectorAll('.foo2'))[0];
    var className = el.className;

  • querySelectorAll in function

     
    var el = (function(selector){return document.querySelectorAll(selector);})('.foo2');
    var className = el[0].className;
