Is there another way to write this JavaScript code?

Can you guys look at my code and see if there's another way to write it. I find it a little repetitive. Here's the link: http://codepen.io/-J0hn-/pen/RoQNeq?editors=0010

The simplest way to reduce this code is to use a for loop as demonstrated below.

// WHEN HOVER THE TRACK NUMBER CHANGES TO A PLAY BUTTON for(i=0; i<12; i++){ $('.inline').eq(i).hover(function() { $('.inline span').eq(i).html('<span class=\'fa fa-play\' style="color:rgb(255,255,255);cursor:pointer;margin-right:-5px;padding-right:0;"></span>'); }, function() { $('.inline span').eq(i).html(i.toString()).css({ 'color': 'rgb(130,130,130)' }); } ); }

// WHEN CLICKED, PLAY BUTTON CHANGES TO PAUSE BUTTON for(i=1; i<13; i++){ $('li span').click(function() { if ($('li span').eq(i).hasClass('fa-play')) { $('li span').eq(i).removeClass('fa-play').addClass('fa-pause'); } else if ($('li span').eq(i).hasClass('fa-pause')) { $('li span').eq(i).removeClass('fa-pause').addClass('fa-play'); } }); }
