Answer 1

那我再回答一次..
<script>
var winHeight=0;function findDimensions() //函数：获取尺寸{//获取窗口高度if(window.innerHeight)winHeight=window.innerHeight;else if((document.body)&&(document.body.clientHeight))winHeight=document.body.clientHeight;
//通过深入Document内部对body进行检测，获取窗口大小if(document.documentElement && document.documentElement.clientHeight && document.documentElement.clientWidth){winHeight=document.documentElement.clientHeight-140;//winWidth=document.documentElement.clientWidth;}
//document.write (winHeight);}findDimensions();window.onresize=findDimensions;
window.onload=function(){
  document.getElementById("Grid").style.height=winheight;
}
</script>
<div id="Grid" style="height:200px;">
