页面高度自适应的JS代码

var deltaW = 10;  //其他元素暂用宽度
var deltaH = 150; //其他元素暂用高度
var main = "main"; //需要自适应高度宽度的div ID
function setWinHW()
{
  if (window.innerHeight)
  {
        //for FF
          winW = window.innerWidth - deltaW ;
          winH = window.innerHeight - deltaH;
  } else
  {
        //for IE
          winW = document.documentElement.offsetWidth - deltaW ;
          winH = document.documentElement.offsetHeight - deltaH - 10;
  }

  var me = document.getElementById(main);
  me.style.width= '' + winW + 'px';
  me.style.height= '' + winH + 'px';
}
window.onresize = function () {setWinHW();};
window.onload = function(){setWinHW();};
