Dynamically Change Height Of IFrame?
May 5, 2009
I've set the page up with an iframe because I figured then I would only have to update menu links on that main page and then there'd be less chance of missing a link somewhere along the way as new updates are added. I know this could probably be accomplished with .css, but I don't know how to do that either!
My problem is that the iframe won't adjust height to allow for the longer pages without adding scroll bar. My neighbor doesn't want it to look like its a separate box at all, so no borders and no scrolling can be used. I've tried the various solutions I've found online and either they do nothing or they stretch the page that's loading in the frame to ridiculous proportions AND still adds a scroll bar.
As I said, I haven't designed in several years and I never learned JavaScript at all. I suspect my problem is probably due to not understanding which bits of code I need to change to my iframe name. The IFrame SSI IV totally confuses me, though I do think that's the one that would ultimately work if I just knew where I was supposed to plug in my iframe name and target info.
My iframe name is, quite simply, "content" and the first page I want loaded (when someone first visits the site) is "whatisreiki.html" (my neighbor does Reiki on animals). The site is www.lovingtheanimals.com but I am working on this particular issue on www.lovingtheanimals.com/iframetest.html so that I don't totally screw up the site where visitors might be affected.

I want to integrate a forum (phpbb) inside my custom made website. The problem is that there is no way to dynamically adjust the iframe height..I thought javascript would be the best way to do that, the problem is that i know nothing about JS... Here is my idea,
-2 scripts, 1 in the parent page (the one with the iframe tag) and the second one in the main forum page
-The script inside the parent page, would dynamically set the "height" parameter inside the iframe tag based on a value passed by the second script.
-The second script, inside the forum page, would read the entire content of the (document.body.scrollHeight) current page and sends its result to the first script.I have found a script that was supposed to do that, but for some reasons it doesnt work very well. Here is the link where i explain de problem with it: http:[url]....

I have the following script resizeing my iframe based on height. The problem is if my site is on one domain say http://mydomain.company.com and the target page is on another domain say http://anotherdomain.mycompany.com the script does not resize the page. I cannot add anything to the pages i am linking to because they live in a CVS repository so i cannot call a function or passs information in that way.
is there any way to make my script work? I'm so fustrated, I'm so close! help!
<!--this script auto resizes the height of the iframe based on contents-->
<script type="text/javascript">
<!--
function resize_iframe(){
document.getElementById("_iframe").height=768 // required for mozilla/firefox bugs, value can be "", null, or integer
document.getElementById('_iframe').height=window.frames["_iframe"].document.body.scrollHeight
}
// -->
</script>
which uses the following iframe
<iframe width=96% id="_iframe" name="_iframe" src="intro.htm" scrolling="no" frameborder="no" ALLOWTRANSPARENCY="true" onload=resize_iframe();></iframe>

I have two monitors (one wide screen, one square) attached to my computer I can verify how it will look in different resolutions.While doing so I came across a nasty thing: in some resolutions the content div is very small and not using all of the full browser window (left after the header section).Is it possible to make a change to the CSS min-height and max-height while the page is being loaded?I've looked into lots of samples but all depend on a click or mouse over event and didn't want to work with onload in the body tag.

I'm looking for a script to change the height of a iframe depending on the loaded content. I found some scripts who let it work when a webpage loads in the iframe.
But when the height of the page changes by javascript animations.
Like a box is getting 200px higher by a javascript action. The page won't reload by this action so the iframe height remains in it's current height.
Anyone has a good script that the iframe height even changed on javascript commands?

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?

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'm trying to create the following visual feature on my page (www.enviromark.ca/Collab/study.html). if you notice, there is a border-right: 1px solid grey; on the 'links' div. I would like to do the following:
onload, i would like the height of the 'links' div to be saved into a variable
i assume this would be done using a variation of 'var minHeight = document.getElementByID('links').offsetHeight'
onclick, i would like the height of the div about to be loaded (aka unhidden) to be saved into a variable... say var newHeight for ex.
IF newheight > minHeight, set document.getElementByID('links').height = 'newHeight' + px;
here's how i tried to code it:
<script language="JavaScript">
function setBorderHeight(divName)
{
var minHeight = document.getElementByID('links').offsetHeight;
var newHeight = document.getElementByID(divName).offsetHeight;
if (newHeight > minHeight)
{
document.getElementByID('links').style.height = 'newHeight' + px;
}
}
</script>
here's an example of a link:
<a class="mainLinks" href="learnMore" onclick="setBorderHeight('learnMore'); ball(this.previousSibling); return toggle('learnMore', 0);"
onmouseover="zxcMseOver(this,1);" onmouseout="zxcMseOver(this,-1);">Learn More</a>
what went wrong?

At this point I have been able to add the row. But what I want to do and am having trouble with is alternating the row colour to the dynamically added row element.
Sample of code I am using:
Code:
var tbody = document.getElementById('tableItems');
var row = document.createElement("tr");
var remainder = tbody.rows.length % 2;
if(remainder) {
row.setAttribute("class", "rowLightGreen");
}
var td1 = document.createElement("td");
td1.appendChild(document.createTextNode(qty));
td1.setAttribute("class","qty");
row.appendChild(td1);
tbody.appendChild(row);
One thing that puzzles me, is that even after adding a row the table my table.rows.length still = 0.
Does anyone know how I can determine the appropriate amount of rows so that I can apply the appropriate class?
Or is there just something blatantly wrong in my approach?

[code]The image's height is 376px. So once the content goes after 376px, the blue bgcolor alternate takes over. But what i want is, once the content crosses the 376px height, the background image should dynamically stretch and not repeat.If this is not possible please do tell me how to increase the height of image in <img> using DOM methods.Again this should increase when the image's original height becomes greater than 376px

I am calling this javascript function:
Inside a nested div so that when a hyperlink is clicked it will show one element and hide the other like this snippet:
The functions works perfectly to expand one div element at a time inside the larger div container. The problem is that when I expand either of the elements by clicking the hyperlink...The larger div container(red gradient square) pushes everything past the background (solid grey square) and screws up the look of the entire page because the div, (which is a few levels up), containing the background is a fixed width, (as a percentage width would not work). I know the exact two widths the background would need to expand to dynamically as a result of the hyperlink being click by a user, but I do not have any idea how to do this from within the aforementioned javascript function I posted. Does anyone have any idea or help for me? It is very confusing as the div I need to resize is a full 3 levels outside of the function call I am working with. As an example the function call is happening in the last div of this flow:
And results in either a div#First or div#Second being generated inside the div#bio. I need to resize the div#greySquareH height property.
Btw the url to the page I am working on is Here. If you want to see any of the other code in the page it is there or I can upload it including the css if I haven't given enough info what I'm working on.

I have a 3 column CSS layout design. The page length is dynamic depending on how much content gets fed into each respective column. For this reason one column might be considerably longer than the other two, as a result the page length opens us white space in some columns.
Given the white space that appears if some content in columns is longer than in others, how could I measure the white space and depending on its height dynamically add in further content providing it fits (say additional side banners)?
I'm told this is possible in JS? I guess PHP is also a viable option?

I have the task of creating an asp page that generates a standard email newsletter. The HTML Image Width and Height tags need to be set to the actual image size (no they haven't been set to a standard size on the server) as they are read in via an while loop. I believe in ASP, you are out of luck for a function that does this, so Javascript may be the way forward.
My code is as follows for the image inside an anchor tag, as you can see i tried the min and max style properties for the image, but this does not set them exactly. e.g. width="120px" height="94px", which is what is required.

When i try to dynamically change the height of an iframe in ie through a java-script to match its content (a html page containing a flash movie, it doesn't resize the iframe at first, but when i reload the same page into the iFrame it resizes as planned, how come?This script works well in firefox, safari and netscape, but i cant get it to work in ie(8, 7). And i get the same problems with every resizing script i've tried. This is the script i use:
<script type="text/javascript">
function adjustIFrameSize(iframe)
{ [code].....
I have a flash menu in the first iframe, the buttons on the menu uses getURL(siteToLoad, "contents") to load another html-page into the iframe "contents". Is it possible to make the iFrame refresh automatically though javascript so that i just refreshes the iframe once? Everytime ive tried that it just ends up in a never ending refresh-loop... How can i make this work? Is there any better script for resizing (and refreshing after resize) the iframe height so that it matches to its content?
