Setup

function hasClass(el, className){
  
  if (el.classList)
    return el.classList.contains(className)
  else
    return new RegExp('(^| )' + className + '( |$)', 'gi').test(el.className)
  }
  
  function selector(selector, callback){
      var els = document.querySelectorAll(selector);
      for (var i = 0; i < els.length; ++i) {
          callback(els[i]);
      }
  }

Teardown



            $('.foo').css('background-color', 'transparent');
  $('.bar').css('background-color', 'transparent');

Test runner

Ready to run.

Testing in
TestOps/sec
Jquery
$('ul.first')
   .find('.foo')
      .css('background-color', 'red')
.end()
   .find('.bar')
      .css('background-color', 'green')
.end();
ready
native javascript
var e = document.querySelectorAll("ul.first li");

for (var i = 0; i < e.length; ++i) {
    if(hasClass(e[i], 'foo'))
         e[i].style.backgroundColor = 'red';

    if(hasClass(e[i], 'bar'))
         e[i].style.backgroundColor = 'green';
}
ready
native javascript two
var elfoo = document.querySelectorAll("ul.first .foo");
var elbar = document.querySelectorAll("ul.first .bar");

for (var i = 0; i < elfoo.length; ++i) {
    elfoo[i].style.backgroundColor = 'red';
}

for (var i = 0; i < elbar.length; ++i) {
    elbar[i].style.backgroundColor = 'green';
}
ready
native with convenience selector function
selector("ul.first .foo", function(element){
    element.style.backgroundColor = 'red';
});

selector("ul.first .bar", function(element){
    element.style.backgroundColor = 'green';
});
ready
Native 3 - element subselects
var first = document.querySelector("ul.first");

var elfoo = first.querySelectorAll(".foo");
for (var i = 0; i < elfoo.length; ++i) {
    elfoo[i].style.backgroundColor = 'red';
}

var elbar = first.querySelectorAll(".bar");
for (var i = 0; i < elbar.length; ++i) {
    elbar[i].style.backgroundColor = 'green';
}
ready
