正确的方法是使用单个计时器。使用
setInterval，您可以实现所需的目标，如下所示：
window.onload = function start() { slide();}function slide() { var num = 0, style = document.getElementById('container').style; window.setInterval(function () { // increase by num 1, reset to 0 at 4 num = (num + 1) % 4; // -600 * 1 = -600, -600 * 2 = -1200, etc style.marginLeft = (-600 * num) + "px"; }, 3000); // repeat forever, polling every 3 seconds}
