不跳动(除了ie6) 总在最右下角

<mce:script type="text/javascript"><!-- window.onresize = window.onscroll = window.onload =function(){ var win_w = document.documentElement.clientWidth ;//窗口宽 var space_w = 0;//左空白宽 if (win_w > 1000) {//窗口大于main 有取左边空白 space_w = (win_w-1000)/2; } if(navigator.userAgent.indexOf("MSIE 6.0")>0) { document.getElementsByTagName('body')[0].style.backgroundAttachment = 'fixed';/*必要，防抖动*/ $e('top').style.setExpression('top','eval( (document.compatMode&&document.compatMode=="CSS1Compat")?' + 'documentElement.scrollTop+documentElement.clientHeight-this.clientHeight-1' + ':' + 'document.body.scrollTop+document.body.clientHeight-this.clientHeight-1)' ); $e('top').style.setExpression('left','eval( (document.compatMode&&document.compatMode=="CSS1Compat")?' + 'documentElement.scrollLeft+documentElement.clientWidth-this.clientWidth-1' + ':' + 'document.body.scrollLeft+document.body.clientWidth-this.clientWidth-1) -' + space_w ); }else { $e("top").style.right = space_w + 5 + 'px'; //设置空白; $e("top").style.bottom = '0px'; //设置下边对齐; }}function $e(objId) { return document.getElementById(objId); } // --></mce:script>

配合

#top{
position:fixed !important;/*ie7 ff*/
position:absolute;
z-index:999;
bottom:0px;
}
