模拟手风琴效果如何实现
现在我不想用任何的框架,也不想用别人封装好的类库,我现在只想用js来改变div的宽度,或者是用js来移动div的位置来实现手风琴效果,请各位大侠们帮帮忙。给几句关键性的提醒就好了。

------解决方案--------------------
参照一下已经封装好的,研究一下吧。

点div,触发div的click句柄。里面维护一个setInterval,改变div的style就行

你可以参考我早些时候的博客。

点下按钮移动,接下来自己发挥:

function move(){
var oldLeft = parseInt(document.getElementById("show").style.marginLeft);
document.getElementById("show").style.marginLeft = oldLeft+2+"";
setTimeout("move()",50);
}
</script>
</head>
<body>
<input type="button" value="移动" onclick="move()"/>
<div id="show" style="width:100px;height:100px;background:red; margin-left:100px;">....</div>
</body>
