不同厂商兼容性代码：
var raf = window.requestAnimationFrame || window.webkitRequestAnimationFrame || window.mozRequestAnimationFrame || window.oRequestAnimationFrame || window.msRequestAnimationFrame || function (callback) {
window.setTimeout(callback, 16);
};
调用：
var boxEl = document.getElementById('box'),
btnEl = document.getElementById('btn');
var dest = window.innerWidth - 100,
speed = 1,
position = 0;
btnEl.addEventListener('click', function () {
requestAnimationFrame(step);
}, false);
function move(ele, position) {
ele.style.transform = 'translate3d(' + position + 'px,0,0)';
}
function step() {
if (position<dest){
position+=speed;
move(boxEl,position);
requestAnimationFrame(step)
}else {
position=dest;
move(boxEl,position)
}
}
