Dynamic iframe height
Question
I have a problem. I'm working on a template which is composed by a central div and an iframe inside it. The div should resize dynamically depending on the content of the iframe. I tried other solutions found here, without results. I'm using the following HTML code:
<div id="site_content" style="position:relative; width:445px; height:500px;">
<iframe id="mainframe" name="mainframe" onload="parent.adjustIFrameHeight();" FRAMEBORDER="0" scrolling="no" style="overflow:hidden; border:none;" src="http://www.letsapp.it/alecianetti/" width="445" height="600"></iframe>
</div>
I would like the div (#site_content) resize dynamically on iframe content change. I tried this function but I'm not very expert in using js and similar (I'm studying them now;)) so I don't know if it's useful or correct
onload="parent.adjustIFrameHeight();"
To give you an idea of the result, I link you a demo site of ThemeForest Wave CV which is the template I'm replicating.
Can anyone help me?

Just tried it out!
<script type="text/javascript">
function setIframeHeight(iframeName) {
//var iframeWin = window.frames[iframeName];
var iframeEl = document.getElementById? document.getElementById(iframeName): document.all? document.all[iframeName]: null;
if (iframeEl) {
iframeEl.style.height = "auto"; // helps resize (for some) if new doc shorter than previous
//var docHt = getDocHeight(iframeWin.document);
// need to add to height to be sure it will all show
var h = alertSize();
var new_h = (h-148);
iframeEl.style.height = new_h + "px";
//alertSize();
}
}
function alertSize() {
var myHeight = 0;
if( typeof( window.innerWidth ) == 'number' ) {
//Non-IE
myHeight = window.innerHeight;
} else if( document.documentElement && ( document.documentElement.clientWidth || document.documentElement.clientHeight ) ) {
//IE 6+ in 'standards compliant mode'
myHeight = document.documentElement.clientHeight;
} else if( document.body && ( document.body.clientWidth || document.body.clientHeight ) ) {
//IE 4 compatible
myHeight = document.body.clientHeight;
}
//window.alert( 'Height = ' + myHeight );
return myHeight;
}
</script>
</head>
<body onload="setIframeHeight('ifr');">
<center>
<iframe id="ifr" src="yourdomain!" onload="parent.adjustIFrameHeight();" width="850px" scrolling="no" ></iframe>
</center>
</body>
