封装动画函数
function animate(obj, target, callback) {
clearInterval(obj.times);
obj.times = setInterval(function() {
var step = (target - obj.offsetLeft) / 10;
step = step > 0 ? Math.ceil(step) : Math.floor(step);
if (obj.offsetLeft == target) {
clearInterval(obj.times);
if (callback) {
callback();
}
}
obj.style.left = obj.offsetLeft + step + 'px';
}, 15)
}
