Javascript implements the method of delayed loading of iframe frame

This article illustrates an example of how javascript can implement delayed loading of iframe frames. Share with you for your reference. The specific implementation method is as follows:

Need to load zone HTML code:

<div id="indexlogin"></div>

The following code is at the bottom

<span id="tmpjsnews"><script type="text/javascript" src=" You call the js" language="javascript"></script></span>

<script type="text/javascript">document.getElementById("indexlogin").innerHTML=document.getElementById("tmpjsnews").innerHTML;</script>

window.onload   =   function()      {         

 frames["BiframeName"].location.href   =   "B.htm";
