title: Hover to change color of canvas
body: <p>I am new in canvas can anyone please help to short this issue.</p>
  
  <p>I create 5 canvas circle. When I hover on any circle I need to change canvas color only, when hover on circle I added one class on canvas but is it possible to change only color. I don't want to create canvas again change only color when hover.</p>
  
  <pre><code>$(document).ready(function(){
   $('.menuballs').hover(function () {
    $(".menuballs").children('canvas').toggleClass('hover-intro');
     if($(this).is(':hover'))
     {
       var c = document.getElementsByClassName("hover-intro");            
       var graphics = c.getContext( '2d' );
       graphics.fillStyle = 'green';
       graphics.fill();
     }
    });
  });
  </code></pre>
  
  <p>Try this as taking hover-intro class but its given HTMLElement, and I need CanvasElement to fill in circle.</p>
