JavaScript - Resizing Iframe
Hi folks! Very, very new to Javascript and I'm having a problem. What I'm trying to do is create a page that uses an iframe to show the fullsized image, while using thumbnails at the bottom. I need the iframe to resize depending on the size of the image since some are landscape and others are portrait oriented. I found a script online that did it for the height of the picture so I tried to modify it to do both the width and the height and haven't had much luck. Here's the code, and I apologize in advance for my noob coding.
Code: <html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>Halloween 2009</title>
<script language="JavaScript">
<!--
function calcWidth()
{
//find the width of the internal page
var the_width=
document.getElementById('preview').contentWindow.
document.body.scrollWidth;
//change the width of the iframe
document.getElementById('preview').width=
the_width;
}
function calcHeight()
{
//find the height of the internal page
var the_height=
document.getElementById('preview').contentWindow.
document.body.scrollHeight;
//change the height of the iframe
document.getElementById('preview').height=
the_height;
}
//-->
</script>
<style type="text/css">
body {background: url(background/bg3.gif); text-align:center}
img {height: 5em; width:5em; display: inline; border: none}
</style>
</head>
<body>
<div style="height: 448px">
<iframe src="Halloween '09 021.jpg" name="preview" id="preview" onLoad="calcWidth();calcHeight();" marginheight="0" marginwidth="0" scrolling="no">

Similar TutorialsI have a master page that has an IFRAME, which we use for resizing. Locally, when we are using our web application within our network, the resizing works perfectly for both Firefox and IE. However, when I access the web application from outside the network the resizing doesn't always work. Most of the time, the offsetheight for the div(container is the name) is not correct, thus I don't see all the results that I need to see in the IFRAME Here is the resizing code below. function resizeTheFrame() { var iframe = document.getElementById('innerFrame'); var containerHeight = document.getElementById('container').offsetHeight; var DefaultPageHeight = 400; if (containerHeight > DefaultPageHeight) { var heightdiff = 100; } else { var heightdiff = DefaultPageHeight - containerHeight; } containerHeight = containerHeight + heightdiff; var counter = parent.top.window.location.href.lastIndexOf("/"); var urlStr = parent.top.window.location.href.substring(0, counter + 1); iframe.src = urlStr + "resizer.htm?height=" + containerHeight; } Good Day Everyone, I need some help resizing an iframe to fit it's content.

This seems to work but it has a few issues, It does not resize properly for every link, only some of them. Can somebody please have a look & tell me where I am going wrong, or provide me with some better code, mine is a bit shoddy! Thanks Harry 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 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? 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. 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. 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. Ok, told you I'd be asking lots of questions ... Code: <div id="resizetest" style="width:200px;height:200px;border:2px solid blue">
<div style="background:#000033">
<a href="#" style="float:right;background:#ffffff" onclick='document.getElementById("resizetest").height="50";'>_</a>
</div>
This is a resize test
</div>
Why doesn't this resize? I've looked at examples, and I don't see what's wrong. Im using the below javascript to resize images on a forum I have created but I want it to ignore 2 certain images that are part of my header. Heres the code Code: <script>
window.onload = resizeimg;
function resizeimg()
{
if (document.getElementsByTagName)
{
for (i=0; i<document.getElementsByTagName('img').length; i++)
{
im = document.getElementsByTagName('img')[i];
if (im.width > 600)
{
im.style.width = '600px';
eval("pop" + String(i) + " = new Function(\"pop = window.open('" + im.src + "','phpbbegypt ','fullscale','width=400,height=400,scrollbars=1,resizable=1'); pop.focus();\")");
eval("im.onclick = pop" + String(i) + ";");
if (document.all) im.style.cursor = 'hand';
if (!document.all) im.style.cursor = 'pointer';
im.title = 'Click Here To See Image Full Size ';
}
}
}
}
</script>
But I want it to ignore 2 images..and not resize them. head1.jpg head2.jpg Any help would be gratefully recieved !! Cheers !! Hi, Am making a user registration page and i want it to be smaller then my other pages and it should open in a new window, something like a popup window. How can i do this? Thanks Hello i would need a 1x1 pixel image for my flagcounter,ive been trying for months [IMG*]http://2.s07.flagcounter.com/count/DymW/bg=ffffff/txt=ffffff/border=ffffff/columns=1/maxflags=1/viewers=3/labels=0/[/IMG*] (the stars for the image not to appear) helllp
I'm coding my new website, and to save bandwidth, i'm letting users link to their own avatars, so I want to resize any images over 150px wide so it doesn't mess up my layout - simple, right? Well, you'd think so, but I don't know any javascript, so i've scrapped this together with what little I know: Code: var obj=document.getElementsByTagName("img");
for(var i=0;i<obj.length;i++){
if(obj[i].className == "avatar") {
if(getElementWidth(obj[i]) > 150) {
obj[i].style.width = 150;
}
}
}
Can anyone help me fix that or code me a new one please? I need it to check all elements (well, images - but only images will be using it) for a width of over 150px, and, if it is - change it to 150px I know it's pretty simple but it's hurting my head! :P Thanks in advance -Alux Hi, Ive written some code to try and resize a page dependant on the content oof an iframe. Code is as follows: Code: window.onload=sizeAdj();
function sizeAdj() {
var elFrame = document.getElementById('theFrame');
var elTable = document.getElementById('tableGrab');
var elDivMain = document.getElementById('main');
var elDivWrapper = document.getElementById('wrapper');
var the_height = elFrame.contentWindow.document.body;
elFrame.height = the_height;
elTable.height = the_height + 90;
elDivMain.height = the_height + 90;
elDivWrapper.height = the_height + 465;
}
I originally thought that I would just be able to resize the iframe and the other elements would follow suit but as you can see Ive tried to resize the other encasing elements also. The code resizes partially in chrome but only to a certain point and not to the full height of the doc content. Help greatly appreciated - full source content attached. Rugby Glass.zip Thanks Sol I have this slideshow, that twirls around but i'm trying to center it within the browser so the middle picture stays in the middle and the side pictures have about a 10px padding from the browsers border. The weird thing is that it adjusts itself when you first open the link, but if you have it open and resize your browser, it won't adjust to the width. Can't figure what i'm doing wrong. I already posted in the HTML/CSS forum but nobody could help. Thanks guys. Check it out he jonathaneiger.com can any one say me how to resize a div by mouse dragging in javascript........ ..first of all is it possible or not?? and if so , what should i do...... hi, deleted old thread, since that didn't answer problem. posting code because of all the dynamic variables would be confusing. so, if anyone can help, here's some link instructions: 1) go to http://www.vehicle411.com 2) in the "vehicle classifieds" panel just click "search" which will bring up 68 vehicles. 3) click on link for any vehicle, which will display vehicle information in a popup window. up to this point everything is fine. BUT when you click the popup's "connect" button to link to a dealership the new window is undersized (actually, if it replaced the original vehicle411 window that would be fine). have tried a lot of different combinations, including the <a href="javascript:photowindow('dealerurl')"> suggested in the other post gives weird result showing javascript:photowindow('dealerurl') in the address window instead of the actual url--meaning it doesn't call the photowindow function. P.S. if you look at the source--all the server values are passed correctly and don't interfere with the code. right now, I've got a simple <a href="dealerurl"> instead of the JS method. Also, have hard coded values to make sure dynamic stuff was working-- and they work. what's really annoying is that I've used just about the same JS code to create that vehicle popups. P.P.S. went back and changed code to using <a href="#" etc. which doesn't work either. but have a direct url for anyone reading this (when clicking on "connect" button it's just creating a copy of itself!!! http://www.vehicle411.com/_system/di...9765108&cid=1# Page with iframe: http://www.siteworksweb.com/bbear2/pretest.html Hi - I have an iframed page which displays the contents of a form. I would like to be able to vary the height of this page depending the form contents (# of rental units returned) returned. Is there a way to resize this page (the 'child' iframe) dynamically according to the size of the form content? I don't have much control over the form data, which lives on a separate domain. Also, is there a way to resize the home page http://www.siteworksweb.com/bbear2/pretest.html back to it's original size when a user clicks the 'back' button in a browser after the form contents are displayed? I would appreciate any input to either of these questions. Thanks in advance for your time, Lisa I am trying to dynamically resize an image. Here is my code: Code: <img border="0" src="images/right.gif" width="16" height="100" name="right">
<SCRIPT Language=Javascript>
<!--
function ChangeImgSize(){
right.height = 3000;
}
ChangeImgSize()
//-->
</SCRIPT>
This is on an asp page, and the <script> tag is the last thing on the page before </body> The image does not get resized. I've been testing the page on current browsers (IE 8, Firefox, Chrome). I'm certain I'm doing something newbish, I don't really know Javascript all that well. Thanks in advance, Skip |
