//左右
function switchSysBarl(){

imgsrc=document.all("makeleft").src;
if (imgsrc.indexOf("menu_close")>1){
document.all("makeleft").src="img/menu_open.gif";
document.all("makeleft").title="显示左边的菜单";
parent.document.all("bbs_left").style.display="none";
}
else{
document.all("makeleft").src="img/menu_close.gif";
document.all("makeleft").title="隐藏左边的菜单";
parent.document.all("bbs_left").style.display="";

参考答案:兄弟,div实现不了100%高度,最多只能自适应高度.你还是在iframe上定高度吧
