<ul>
  <li>Ruby</li>
  <li>JavaScript</li>
  <li>PHP</li>
</ul>
  $('li').each(function(index, element){
    console.log(index + ':' + $(element).text());
  })

以下のように出力される。

2:PHP

配列・オブジェクトに対する繰り返し


var array = ['Rails', 'jQuery', 'FuelPHP'];

$.each(array, function(index, value){
  console.log(index + ':' + value);
