1) Script Title: Iframe SSI script II

2) Script URL (on DD): http://www.dynamicdrive.com/dynamicindex17/iframessi2.htm

3) Describe problem: Is there any way to show a loading indicator while the content within the iframe is being loaded? If for some reason the connection is taking long or the content is taking a long time to load, a loading indicator will show letting the user know that something is happening? Is this possible for pages from the same domain?

I'm trying to change a html site around using AJAX iframes instead of the regular frame so its automatically resized according to the page..

http://www.desihotcuts.com/2/index-4.html this is a sample page that uses this script..

thanks in advance

I got help and this is how it works:

put this in the head section

<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

***********************************************/

//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? 20 : 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"
}
}
document.getElementById('loading').innerHTML = '';
}


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>

and then you need to have a loading.gif image that you want to display

put this code where you want the iframe:

<div id='loading'><div align="center">Loading...<img src="loading.gif"></div></div>
<iframe id="myframe" src="http://www.yourpagehere.com" scrolling="auto" marginwidth="0" marginheight="0" frameborder="0" vspace="0" hspace="0" style="overflow:visible; width:100%; display:none"></iframe>

the center is not needed but makes it look a little better when its being displayed

try it out.... it should work... : )
