在main.js裏面添加:
(function () { var lastTime = 0; var vendors = [‘ms‘, ‘moz‘, ‘webkit‘, ‘o‘]; for (var x = 0; x < vendors.length && !window.requestAnimationFrame; ++x) { window.requestAnimationFrame = window[vendors[x] + ‘RequestAnimationFrame‘]; window.cancelAnimationFrame= window[vendors[x] + ‘CancelAnimationFrame‘] || window[vendors[x] + ‘CancelRequestAnimationFrame‘]; } if (!window.requestAnimationFrame) { window.requestAnimationFrame = function (callback, element) { var currTime = new Date().getTime(); var timeToCall = Math.max(0, 16 - (currTime - lastTime));var id = window.setTimeout(function () { callback(currTime + timeToCall); }, timeToCall); lastTime = currTime + timeToCall; return id; }; } if (!window.cancelAnimationFrame) { window.cancelAnimationFrame = function (id) { clearTimeout(id); }; } }());
