JavaScript native and jquery libraries implement iframe adaptive height and width_jquery

Javascript native and jquery library implement iframe adaptive content height and width---it is recommended to use jQuery code!

&#8205;<iframe src="index.php" id="mainiframe" name="mainiframe" width="100%" frameborder="0" scrolling="no" marginwidth="0" marginheight="0"></iframe>

Code based on Jquery library is easy to implement:

<script language="javascript" type="text/javascript"> 
$(document).ready(function(){ 
$("#mainframe").load(function(){ 
$(this).height(0); //用于每次刷新时控制IFRAME高度初始化 
var height = $(this).contents().height() + 10; 
$(this).height( height < 500 &#63; 500 : height ); 
}); 
}); 
</script>

‍ Implementation based on JS native code:

<script language="javascript"> 
if (window.parent.length>0){window.parent.document.all.mainframe.style.height=document.body.scrollHeight;} 
</script>
