JavaScript 之 iframe自适应问题---可以用来实现网页局部刷新

1.HTML

<iframe src="index.html" id="iframepage" frameborder="0" scrolling="no" marginheight="0" marginwidth="0" onLoad="iFrameHeight()"></iframe>

2.javascript

<script type="text/javascript" language="javascript">  

function iFrameHeight() {  

var ifm= document.getElementById("iframepage");  

var subWeb = document.frames ? document.frames["iframepage"].document : ifm.contentDocument;  

if(ifm != null && subWeb != null) {

   ifm.height = subWeb.body.scrollHeight;

   ifm.width = subWeb.body.scrollWidth;

}  

}  

</script>
