JS实现iframe自适应高度的方法(兼容IE与FireFox)

<scriptlanguage="javascript">
function adjustFrameSize()
{
  var frm = document.getElementById("iframe1"); //将iframe1替换为你的ID名
  var subWeb = document.frames ? document.frames["iframe1"].document : frm.contentDocument;
  if(frm != null && subWeb !=null)
  {
   frm.style.height="0px";//初始化一下,否则会保留大页面高度
   frm.style.height = subWeb.documentElement.scrollHeight+"px";
   frm.style.width = subWeb.documentElement.scrollWidth+"px";
   subWeb.body.style.overflowX="auto";
   subWeb.body.style.overflowY="auto";
  }
}
</script>

//修改父窗口地址
function changeHeight(){
window..location.hash = "#height=" + $(document).height();
}

//高度自适应
var iframe = document.getElementById("iframe1");
function iframeHeight() {
  var hash = window.location.hash.slice(1), h;
  if (hash && /height=/.test(hash)) {
    h = hash.replace("height=", "");
    iframe.style.height = h+"px";
    window.location.hash = "#temp";//防止点击其他页面时高度不变
  }
  setTimeout(iframeHeight, 100);
}
iframeHeight();
