    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');
    var className = el.className;

  • querySelectorAll (.id)

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

  • Cash (#id)

     
    var el = $("#foo");
    var className = el.className;

  • Cash (.id)

     
    var el = $(".foo2");

  • Cash (tag#id)

     
    var el = $("div#foo");
    var className = el.className;

  • Cash (tag.id)

     
    var el = $("div.foo2");
    var className = el.className;

  • Cash + getElementById

     
    var el = $(document.getElementById("foo"));
    var className = el.className;

  • Cash + getElementsByClassName

     
    var el = $(document.getElementsByClassName("foo2"));
    var className = el.className;

  • jQuery (#id)

     
    var el = jQuery("#foo");
    var className = el.className;

  • jQuery (.id)

     
    var el = jQuery(".foo2");
    var className = el.className;

  • jQuery (tag#id)

     
    var el = jQuery("div#foo");
    var className = el.className;

  • jQuery (tag.id)

     
    var el = jQuery("div.foo2");
    var className = el.className;

  • jQuery + getElementById

     
    var el = jQuery(document.getElementById("foo"));
