    Here is a snippet example :

    <button onclick="start()">start</button>
       var animId=false;
       function start() {
       function loop() {
          //your code here
       // I added this in case you wanted to call a stop
       function stop() {
          animId && cancelAnimationFrame(animId);

    If you want to call requestAnimationFrame(loop) you should do it like this...

    <button type="start" form="form1" value="start" onclick="requestAnimationFrame(loop)">start</button>
