iframe自適應高度

無廢話，網上很多文章一下寫了幾種實現方式，代碼短點的呢用不了，長點的呢眼睛都看花

下面的代碼在火狐、IE上正常

 

<script type="text/javascript">
function reinitIframe(){
var iframe = document.getElementById("mainFrame");
try{
var bHeight = iframe.contentWindow.document.body.scrollHeight;
var dHeight = iframe.contentWindow.document.documentElement.scrollHeight;
var height = Math.max(bHeight, dHeight);
iframe.height = height;
}catch (ex){}
}
window.setInterval("reinitIframe()", 200);
</script>
