javascript 缓冲效果实现代码推荐

菜鸟版代码如下:
理解这段代码就基本上掌握了
复制代码代码如下:
function f_s() {
var obj = document.getElementById("top");
obj.style.display = "block";
obj.style.height = "1px";

var sw = function () {
var s_width = parseInt(obj.style.height);
if (s_width < 350) {
obj.style.height = (s_width + Math.ceil((350 - s_width) / 15)) + "px";
}
else {
clearInterval(st);
}
}
var st = window.setInterval(sw, 1);
}

中级版本
复制代码代码如下:

function Scroll(obj, h, s){
if(obj == undefined){return false;}
var h = h || 200;
var s = s || 1.2;
var obj = typeof(obj)=="string"?document.getElementById(obj):obj;
var status = obj.getAttribute("status")==null;
var oh = parseInt(obj.offsetHeight);
obj.style.height = oh;
obj.style.display = "block";
obj.style.overflow = "hidden";
if(obj.getAttribute("oldHeight") == null){
obj.setAttribute("oldHeight", oh);
}else{
var oldH = Math.ceil(obj.getAttribute("oldHeight"));
}
var reSet = function(){
if(status){
if(oh < h){
oh = Math.ceil(h-(h-oh)/s);
obj.style.height = oh+"px";
}else{
obj.setAttribute("status",false);
window.clearInterval(IntervalId);
}
}else{
obj.style.height = oldH+"px";
obj.removeAttribute("status");
window.clearInterval(IntervalId);
}
}
var IntervalId = window.setInterval(reSet,10);
return status;
}
