JavaScript - Resize Iframe Depending On The Height Of The Iframe Contents
Is there a way to resize an iframe dynamically so that you never get the scroll bar and essentially hide that there is an iframe? Better integration really.
Basically I want to iframe a forum into my site so that the design down the sides and top which my friend does using iweb are not messed with. We have a central area which can be longer or shorter depending on the forum. Similar TutorialsHi there, I am looking to retrieve the hieght of the browser window, so that when my index page loads, it will automatically resize an iframe that i have to fill the remaining hieght of the window. The image above shows the location of the iframe, and the problem that i am facing. Currently, the height of the iframe is hardcoded. On my laptop screen the iframe looks as if it fills the remaining 100% of the height. However, when viewing this page on my 17in monitor, there is now an ugly white space. I would like to be able to dynamically change the height of the iframe, so that it can fill up that white space with more iframe height. (1) shows the current hard-coded height of the iframe, and (2) shows the height that i would like to be able to retrieve using javascript. If i can get this value, then i assume all i then need to do is to substract the number of pixels that are taken up by the image, and the two nav bars at the top. Hopefully this would then give me the iframe filling up all available white space. The code i have currently to set the iframe height is: Code: <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 && iframeWin ) {
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
iframeEl.style.height = 100 + "%";
alert(document.height);
}
}
</script>
</head>
<body onload="setIframeHeight('ifrm');">
So, I am now able to change the height of the iframe when the page loads, i just now need to hopefully be able to get the value from (2) in the image, to make it all work out nicely. Is this possible? Any help or advice will be greatly appreciated! Thanks in advance Hi, Not sure if I worded that question right. I have a web page which will display another web page in an iframe. But the content inside the iframe may change while the user interacts with it so I need to be able to resize the iframe height from code on the page inside the iframe. Any tips on how I can do that? I am using php and javascript. Thanks. Hello, I have build a tree view forum, I have used the iframe tag to import it to my wordpress blog . I have a script that determine the size of the iframe on load: Code: <script language="JavaScript">
<!--
function calcHeight()
{
//find the height of the internal page
var the_height=
document.getElementById('the_iframe').contentWindow.
document.body.scrollHeight;
//change the height of the iframe
document.getElementById('the_iframe').height=
the_height;
}
//-->
</script>
The problem with the script is that the forum(tree view forum) only shows topics. I have another script that displays the contents of any issue only while clicking (Void). In actual the contents of each issue is charging ahead - but the resize function of the Iframe script not see it. How do I fix it, that the size of the Iframe will change automatically? Thanks alot I have a very simple page that has one iframe on it. What I would like to accomplish is having Javascript read the contents of the iframe and write it to the page. I have tried numerous coding samples found all over the web but nothing seems to work for me as I am a major Javascript noob. The iFrame will include content like the following which will be from an outside web server; Code: <?xml version="1.0" encoding="UTF-8" standalone="yes"?><response><results><![CDATA[Success]]></results></response> Thanks a lot in advance! I have an iframe on my page which begins at 300x250. Onclick from an outside control (button), I have it resizing to 720x405. What I need it to do on that same click is change position on the page as well as resize (top, left.) Any way I can do this? Here's my resize script and the accoutrements with it... <!---Begin head section here---> <head> <!---Begin Style Section Here---> <style> .fauxButton { background: buttonface; font: menu; border: 1px outset white; cursor: default; padding-left: 6; padding-right: 6; padding-top: 2; padding-bottom: 1; border-top: 1px solid buttonhighlight; border-left: 1px solid buttonhighlight; border-right: 1px solid buttonshadow; border-bottom: 1px solid buttonshadow; height: 20px; } </style> <!---End Style Section Here---> <script language="JavaScript"> function resizeIframe(iframeId, iframeHeight, iframeWidth) { if (iframeWidth>0) { document.getElementById(iframeId).style.width=iframeWidth; } if (iframeHeight>0) { document.getElementById(iframeId).style.height=iframeHeight; } } </script> </head> <!---End head section here---> <body> <iframe name=video_iframe id=video_iframe frameborder="0" src="player.asp" scrolling=no allowtransparency="true" style="position:absolute; width:300px; height:250px; top:361px; left:720px;align:top; align:left; border:0px solid #FF0000; background-color:#FFFFFF; padding:0px 0 0; z-index:3;"> </iframe> <a id="widenButton" class=fauxButton onclick="resizeIframe('video_iframe', 420, 720);document.getElementById('widenButton').style.display='none';document.getElementById('narrowButt on').style.display='inline';" style="display:inline;">Wide -></a> <a id="narrowButton" class=fauxButton onclick="resizeIframe('video_iframe', 250, 300);document.getElementById('narrowButton').style.display='none';document.getElementById('widenButt on').style.display='inline';" style="display:none;"><- Narrow</a> </body> Thanks in advance, Miz Parker Hi all, I have an iframe on my page and I added the following code to detect the iframe file height to avoid scrolling which is working fine. Code: <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;

<body onload="setIframeHeight('ifrm');">

</iframe>
There is a form in the iframe and it is coming from a third party web site which I have no access. My problem is when a client submits the search form in the iframe search results page is higher than the search main page and half of search results page is not shown. Is there a way to sense that the page in the iframe is changed and resize the iframe height accordingly? Thanks Ceyhun I am having difficulties with Internet Explorer and cannot find a solution online. The code in question is at http://www.blainegregson.com/news.php. The iFrame resizes for Firefox, Chrome, and Safari but not for IE. Also, I don't know javascript and thus found this code online. Here is the sample code: Code: <Script type="text/javascript">
function setIframeHeight(iframeName) {
var iframeEl = document.getElementById? document.getElementById(iframeName): document.all? document.all[iframeName]: null;
if (iframeEl) {
iframeEl.style.height = "auto";
// need to add to height to be sure it will all show
var h = alertSize(iframeName);
iframeEl.style.height =h + "px";
}
}
function alertSize(frameId) {
var myHeight = 0;
frame = document.getElementById(frameId);
if( typeof( window.innerWidth ) == 'number' ) {
//Non-IE
var getFFVersion=navigator.userAgent.substring(navigator.userAgent.indexOf("Firefox")).split("/")[1];
var FFextraHeight=parseFloat(getFFVersion)>=0.1? 16 : 0;
myHeight=frame.contentDocument.body.offsetHeight+FFextraHeight;
} else if( document.documentElement && ( document.documentElement.clientWidth || document.documentElement.clientHeight ) ) {
//IE 6+ in 'standards compliant mode'
innerDoc = (frame.contentDocument) ? frame.contentDocument : frame.contentWindow.document;
myHeight= innerDoc.body.scrollHeight + 10;
//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;
}

I am building iframes from database entries. Is it possible to resize them with an onclick event?
In my page, I have a main iframe where I want all the content of my links to be loaded. I want the iframe's height to resize according to the content. All the linked pages are in the same domain. I have tried some scripts I found, but nothing has the result I want. The HTML code is: Code: <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>index</title> <link href="styles.css" rel="stylesheet" type="text/css" /> </head> <body> <div id="container"> <div id="header"></div> <div id="nav"> <a href="home.html" target="frame">Home</a> <a href="the_band.html" target="frame">The Band</a> <a href="News.html" target="frame">News</a> <a href="gallery.html" target="frame">Gallery</a> <a href="contact.html" target="frame">Contact</a> </div> <iframe id="frame"></iframe> <div id="footer"></div> </div> </body> </html> The CSS code is: Code: div#container {

I don't know how to make scripts on my own, so I would appreciate any help. Thank you! Hi all let me start off by saying: "AAAAAAHHHHHHHAAAAAAA" Feel better now! I have an iFrame which loads individual pages from my site, I am using javaScript to tell the iFrame to resize to the size of the page that is being loaded, the problem is when I click on the link the iFrame does not resize but if I click on the link again it does resize! The fuction is called but only the second time round. Also the none of the script works in FireFox! HELP PLZ! My Code: Code: <SCRIPT LANGUAGE=javascript>
<!--
function reSize()
{
try{
var oBody = ifrm.document.body;
var oFrame = document.all("ifrm");
oFrame.style.height = oBody.scrollHeight + (oBody.offsetHeight - oBody.clientHeight);
}
//An error is raised if the IFrame domain != its container's domain
catch(e)
{
window.status = 'Error: ' + e.number + '; ' + e.description;
}
}
//-->
</SCRIPT>

Hi! I have a mysql database with a bunch of quotations in it. I created a blog at http://aro2220.blogspot.com At the top of the blog is an iframe window that directs to http://aro2220.com/blog On that page it uses php to pull out a random quote from the database. The iframe window displays that quote onto the blog. It works great except that the height is not automatically resizing. Is there a way I can use javascript to do this instead? Here is some pseudo-code of what I'd like to be able to do: (p.s. I do not know javascript or much of anything so I am looking for people to tell me how to ACTUALLY do this) Quote: var stringvariable = http://aro2220.com/blog/index.html; int stringlength = stringlength(stringvariable); int autosize = 200 + stringlength * 5; <iframe width="100%" frameborder="0" src="http://aro2220.com/blog" height=$autosize scrolling="no"></iframe> Obviously these are not real functions or proper syntax but hopefully it will paint a clear picture on what I am trying to do. Hi, I would like to know how I can use JavaScript to find the size of my iFrame and feed it to Shadowbox to launch the appropriate sized shadowbox on different browsers and resolutions. For me, the parent page is called 'demo.html' and the iFrame is 'gallery/archive_iframe.html'. Currently, the shadowbox is launched with a fixed height and width (which you will see in the HTML code below). The problem is that 'gallery/archive_iframe.html' displays differently on every browser and every resolution, causing unwanted horizontal and vertical scroll bars. An example can be seen he http://www.mikegermond.com/demo.html Here is the code that I use in 'demo.html' to launch the iFrame: Head Code: <script type="text/javascript" src="/shadowbox/libraries/mediaplayer/jquery.js"></script>
<script type="text/javascript" src="/shadowbox/shadowbox.js"></script>
<script type="text/javascript" src='/shadowbox/libraries/mediaplayer/swfobject.js'></script>
<script type="text/javascript">
function moveCloseLink(){
var cb=document.getElementById('sb-nav-close');
var tb=document.getElementById('sb-title');
if(tb) tb.appendChild(cb);
}
Shadowbox.init({
onOpen: moveCloseLink,
flvPlayer: '/shadowbox/player.swf',
language: 'en',
players: ["flv","iframe"],
flashParams: {allowfullscreen:'true'},
flashVars: {
skin: '/shadowbox/modieus.swf',
image: '/upload/demo-poster.jpg',
autostart: true
}
});
</script>
Body Code: <A HREF="/gallery/archive_iframe.html" rel="shadowbox;width=750;height=486" class="imgLink" title="Video Archive"><img src="gallery/videoarchive_thm.jpg" alt="Launch Video Archive (popup window)" width="260" height="162" border="0" /></A> What do I need to do in 'gallery/archive_iframe.html' if anything? My thought is that I need to wrap it in a DIV tag and find the width and height of that. And what do I need to do in 'demo.html'? I'd assume some code is needed to pull the dimensions discovered in my iframe document, and insert those into the link that launches Shadowbox. Consider me a JavaScript newbie! You're help is greatly appreciated!! http://isensors.com.sg/isensors-GJ/ That's the page I'm working on now, the script I'm using from he http://www.frontpagewebmaster.com/m-89000/tm.htm posted by collide007. It allows me to resize my iframe when a new page loads in it, it's working fine on Chrome and Firefox. For safari, the iframe expands but does not contract when a smaller page is loaded in. The code doesn't even work in IE. <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=["contentframe", "newsframe"] //Should script hide iframe from browsers that don't support this script (non IE5+/NS6+ browsers.

Thanks. Hi people, I'm new to this and I was wondering how to adjust the iframe height by itself if my html height increases. My html code includes a facebook comment at the bottom of my page and the comment will show making it expand the height once users post comments. On the other hand, I'm using a CMS that have its own iframe. I've tried many solutions that can be found on the web but none works. It only can work if I don't put in CMS. Is it possible to adjust the iframe height using CMS or there is no way? I hope you guys understand what I'm trying to say. Hope to hear from you guys soon. Thanks alot. Hi there everybody, I've got this problem which I can't solve myself... I've got a website which has 3 colums and is hosted on domain1.com. in the right column I've got an Iframe which loads content from domain2.com . this content are some textboxes and a datepicker tool. if I press the 'search'-button in this Iframe I would like to refresh the mainpage (from domain1.com) so that another Iframe appears in the middle column. in this column i would like to load a new form from domain2.com which contains the values that I've put in in the form from the right Iframe. Unfortunally I can't get this to work... Will somebody please help me? Hi all, I hope you can help I have some code which: 1) Opens a URL (e.g. google.com) in a hidden iframe, then 2) Redirects the visitor to a different URL (e.g. yahoo.com) after it has loaded... This works exactly as I need. What I'd like to do is the following: 1) Open a URL (e.g. google.com) in a hidden iframe, then 2) Redirect the visitor to a different URL (e.g. yahoo.com) in a full-screen iframe 3) The address bar of the full-screen iframe should be my domain (obviously!) Here's what I have so far... Hidden iframe -> New URL Code: Code: <html>
<body>
<script type="text/javascript">
var page_body = document.getElementsByTagName('body');
var myframe = document.createElement('iframe');
var id = Math.random();
myframe.setAttribute('id', 'myFrame'+id);
myframe.src = 'http://google.com'; //First open Google in hidden iframe
myframe.setAttribute('frameborder', '0')
myframe.setAttribute('width', '0');
myframe.setAttribute('height', '0');
if (myframe.attachEvent)
{
myframe.attachEvent('onload', function()
{
top.location = 'http://yahoo.com'; //Once loaded redirect to Yahoo -- but the address bar shows yahoo.com -- I want the address bar to display mydomain.com/page.html
});
}
else if (myframe.addEventListener)
{
myframe.addEventListener('load', function()
{
top.location = ('http://yahoo.com');
}, false);
}
page_body[0].appendChild(myframe);
</script>
</body>
</html>
I have an example of some code which displays the full screen iframe, but my problem is... ...I can't figure out how to redirect to this after the hidden iframe has loaded Here's an example of how I want the redirect to display -- after the initial hidden iframe has loaded: Code: <html>
<head>
<script type="text/javascript">
function sendParams() {
document.body.style.overflow = "hidden";
}
</script>
</head>
<body>
<!--Open Yahoo.com in a full screen iframe, and disable extra scrollbar -->
<iframe height="100%" width="100%" frameBorder="no" onload="sendParams()" src="http://yahoo.com"></iframe>
</body>
</html>
I've been beating my head against the wall today trying to figure this out, and I'm fresh out of ideas. If you can help, you'll have some serious gratitude and good karma thrown your way! Best wishes, and thanks in advance, Paul I'm wondering if anyone out there has a jquery solution to using an iframe that automatically adjusts it's height of the child and also works cross domain. Any help would be greatly appreciated. I have used iframes for my site and found various javascripts so when a person clicks on say the audio page he http://www.krillmeed.com/index.html it takes them to the audio page but will load it into the index.html page. The problem is, especially with search engines, to point to that page, this is what the URL looks like to send someone to that page: http://www.krillmeed.com/?frame=0&sr...m%2Faudio.html which is not very clean at all, this is the javascript that i found that at least works: Child iframe script: Code: <script type="text/javascript">
(function(){
var qstr = '?frame=0&src=' + encodeURIComponent(location.href),
lre = new RegExp('^' + location.protocol + '//' + location.hostname + '(()|(/)|(/index.html)|(/index.php))(()|(\\' + qstr + '))$');
if (!lre.test(parent.location.href)){
top.location.href = '/' + qstr;
}
})();
</script>
Parent iframe Script: Code: <script type="text/javascript">
(function(){
function getQval(n) {
if(typeof n !== 'string'){
return null;
}
var r = new RegExp('[?&;]' + n + '=([^&;#]*)'), m = location.search;
return (m = r.exec(m))? unescape(m[1]) : null;
}
var f = getQval('frame'), s = getQval('src');
if(f && frames[f] && s && s.indexOf(location.protocol + '//' + location.hostname + '/') === 0){
frames[f].location.href = s;
}
})();
</script>
Is there a "cleaner" way of doing this? This was an old code, i have yet to find a more modern one. Thank you in advance. |
