    问题简单 赚点分先<body>
    <div id="a" style="width:500px; height:300px; position:absolute; background:#000000; left:0px; top:0px;"></div>
    </body>
    <script>
    var timer
    var obj=document.getElementById("a")
    var Opacity =100
    function disapper(){
    obj.style.filter = "Alpha(opacity="+Opacity+")";
    Opacity=Opacity-2
    if(Opacity!=0)
    {timer=setTimeout("disapper()",50)}
    else
    {clearTimeout(timer)
    obj.parentNode.removeChild(obj)
    }
    }
    function window.onload(){
