Height web page
Hi guys
Is there a function that retrieves the height in pixel of a whole web page?

Re: Height web page
This should help, it uses IFrame (needs to be in HTML)
PHP Code:
<script type="text/javascript">
/***********************************************
* IFrame SSI script II- © Dynamic Drive DHTML code library (http://www.dynamicdrive.com)
* Visit DynamicDrive.com for hundreds of original DHTML scripts
* This notice must stay intact for legal use
***********************************************/
//Input the IDs of the IFRAMES you wish to dynamically resize to match its content height:
//Separate each ID with a comma. Examples: ["myframe1", "myframe2"] or ["myframe"] or [] for none:
var iframeids=["myframe"]
//Should script hide iframe from browsers that don't support this script (non IE5+/NS6+ browsers. Recommended):
var iframehide="yes"
var getFFVersion=navigator.userAgent.substring(navigator.userAgent.indexOf("Firefox")).split("/")[1]
var FFextraHeight=parseFloat(getFFVersion)>=0.1? 16 : 0 //extra height in px to add to iframe in FireFox 1.0+ browsers
function resizeCaller() {
var dyniframe=new Array()
for (i=0; i<iframeids.length; i++){
if (document.getElementById)
resizeIframe(iframeids[i])
//reveal iframe for lower end browsers? (see var above):
if ((document.all || document.getElementById) && iframehide=="no"){
var tempobj=document.all? document.all[iframeids[i]] : document.getElementById(iframeids[i])
tempobj.style.display="block"
}
}
}
function resizeIframe(frameid){
var currentfr=document.getElementById(frameid)
if (currentfr && !window.opera){
currentfr.style.display="block"
if (currentfr.contentDocument && currentfr.contentDocument.body.offsetHeight) //ns6 syntax
currentfr.height = currentfr.contentDocument.body.offsetHeight+FFextraHeight;
else if (currentfr.Document && currentfr.Document.body.scrollHeight) //ie5+ syntax
currentfr.height = currentfr.Document.body.scrollHeight;
if (currentfr.addEventListener)
currentfr.addEventListener("load", readjustIframe, false)
else if (currentfr.attachEvent){
currentfr.detachEvent("onload", readjustIframe) // Bug fix line
currentfr.attachEvent("onload", readjustIframe)
}
}
}
function readjustIframe(loadevt) {
var crossevt=(window.event)? event : loadevt
var iframeroot=(crossevt.currentTarget)? crossevt.currentTarget : crossevt.srcElement
if (iframeroot)
resizeIframe(iframeroot.id);
}
function loadintoIframe(iframeid, url){
if (document.getElementById)
document.getElementById(iframeid).src=url
}
if (window.addEventListener)
window.addEventListener("load", resizeCaller, false)
else if (window.attachEvent)
window.attachEvent("onload", resizeCaller)
else
window.onload=resizeCaller
</script>
Is this what you mean ¿

 Re: Height web page
It depends on your browser.
I have tested the following lines with Internet Explorer 5.5 and Firefox.
HTML Code:
<html>
<body>
<script language=javascript>
alert(screen.height);
alert(screen.width);
if (document.all) {
// I.E.
alert(document.body.clientHeight);
alert(document.body.clientWidth);
}
else {
// Firefox and maybe also Netscape, Mac Opera
alert(window.innerHeight);
alert(window.innerWidth);
}
</script>
</body>
</html>

That is the functionality I use myself as well.......

Netscape runs similar to FireFox, so that is an affermative 
And I can (from personal usage) confirm that Opera uses this part as well, or at least the latter versions of Opera
I'm not sure about Safari (Mac) however, seeing as I haven't tested that one with this script.
