IMPLEMENTING SELF-SIZING IFRAMES
CMS Implementation:
-
You must create an alternate header for the page you wish to use this technology in.
-
In this header, copy and paste the following code, making sure you put it between the <head> </head> tags:
-
<script type="text/javascript">
//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>
-
When you create your CMS page, make sure you select the alternate header that contains the self-sizing code.
-
Call your iFrame using the following code: Modify where necessary to set the source URL.
-
<div style="WIDTH: 588px; HEIGHT: 89.12%">
<iframe id="myframe" style="OVERFLOW: visible; WIDTH: 100.16%; HEIGHT: 800px" marginwidth="0" marginheight="0" src="your path/your filename.ext" frameborder="0" scrolling="no"></iframe></div>
-
Very Important
: Make sure that the Iframe id value (myframe is the value used in this example) matches the value(s) in the iframeids variable used in the self-sizing code in the header (see line 3 in that codebase...var iframeids=["myframe"]).
- You can change the size by changing the height and width properties above.
Standard Website Implementation:
-
Follow the steps above, omitting any instructions pertaining to the DirectControl CMS system.
