function test(){
var infoHeight = document.getElementById("info").scrollHeight;
var bottomHeight = document.getElementById("bottom").scrollHeight;
var allHeight = document.documentElement.clientHeight;

var bottom = document.getElementById("bottom");
if((infoHeight + bottomHeight) < allHeight){
  bottom.style.position = "absolute";
  bottom.style.bottom = "0";
}else{
  bottom.style.position = "";
  bottom.style.bottom = "";
}

setTimeout(function(){test();},10);
}
test();

("info")和("bottom")应该怎处理？？

版主在吗？
