1. The processing of the adaptive height of iframe under the same domain name
Copy Code code as follows:
<iframe onload= "Javascript:setiframeheight (This)" src= ". /home/b "id=" Win "Name=" Win "width=" 100% "height=" 1 "> </iframe>
Of course here I'm using asp.net MVC where SRC is set to the routing structure
Copy Code code as follows:
<script type= "Text/javascript" >
function Setiframeheight (obj) {
var win = obj;
if (document.getElementById) {
If (Win &&!window.opera) {
if (win.contentdocument && win.contentDocument.body.offsetHeight)
Win.height = Win.contentDocument.body.offsetHeight;
else if (win. Document && win. Document.body.scrollHeight)
Win.height = win. Document.body.scrollHeight;
}
}
}
</script>
Use is the iframe nested pages loaded, use the OnLoad event to get the height of the Web page nested in the IFRAME, and then assign value to the height of the IFRAME can be.
2. Cross-domain iframe height adaptive
Copy Code code as follows:
When the home page and the nested IFRAME are different domain names, it's a bit cumbersome to avoid JavaScript cross-domain restrictions.
Principle: The existing IFRAME homepage main.html, is the iframe nested page iframe.html, the IFRAME intermediary page agent.html three, through main.html (domain name for http:// www.ccvita.com) nested iframe.html (domain name: http:// Www.phpq.net), when the user browses the execution iframe.html the JavaScript code setting IFRAMEC's SCR address to add the IFRAME page height, agent.html (domain name: http:// www.ccvita.com) Gets the height of the pass, setting the height of the iframe in the main.html through JavaScript. Ultimately achieve the desired goals.
IFRAME Home Face main.html

IObj.style.height = Iobjh.split ("#") [1]+ "px";
}
Pseth ();
</script>
</body>
In the code, the Kimi possible path representation is not complete
Main.html and agent.html must be in the same domain.
and iframe.html in another domain
