Measuring Column Height And Dynamically Adding Content?
Jul 21, 2010
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 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 am facing a certain problem when I try to add a content to a page dynamically and then save the page. I add a content dynamically to the page on a mouse click and then after the content appears in the screen, I try to save the HTML file from the browser. When I open the saved HTML file, I am not able to see the dynamically added text. This happens only in IE.
This is the code that I use.
"document.body.insertAdjacentHTML("beforeEnd", "<div id='idCanvas'> Sample Text </div>");"
This code successfully adds the new text to the page. But, when I try to save the page from "File -> Save As" and then open the saved file, I am not able to view that text. I need to get that text in the saved document as well.
I also tried using:

how to make my left hand column DIV (my site nav) match the same height of the main content DIV.
Im pretty clueless at JS but guess this is way to do it:
* Capture the height attribute of the main DIV from the DOM into a variable
* Copy this value into the height attribute of the left hand DIV and hey presto they match?

I came across JQuery when searching for a solution to get matching column height with Divs. I have downloaded JQuery which appears to be one file named jquery-1.3.2.min I also have the following short script that I found, which I believe goes in the head area of the page.
The script works with jquery.
HOW TO DO:
1. I assume I need to rename my download file jquery-1.3.2.min to jquery.js ?
2. Do I need to edit the jquery file somehow in order to get the above script to work?

As the title suggests, I want to grab the height of the center column and force my left and right columns to be the same height. The bit of code below is from MyWebTronics, and it's great (awesome job, Jason!)... but it is designed to grab the tallest column (regardless which one it is) and then set all the rest to the that same size.
Code JavaScript:
<script language="javascript" type="text/javascript">
fixHeight=function(){
var divs,contDivs,maxHeight,divHeight,d;
maxHeight=0;
contDivs=[];
divs=document.getElementsByTagName('div');
// get all <div> elements in the document
for(var i=0;i<divs.length;i++){ // for all divs...
if(/"fixheight"/.test(divs[i].className)){
// find those with the class attribute 'fixheight'...
d=divs[i];
contDivs[contDivs.length]=d;
// determine their height, defined as either offsetHeight or pixelHeight
if(d.offsetHeight){ divHeight=d.offsetHeight; }
else if(d.style.pixelHeight){ divHeight=d.style.pixelHeight; }
// Keep track of the largest div height
maxHeight=Math.max(maxHeight,divHeight);
}} // assign all divs the height of the tallest div
for(var i=0;i<contDivs.length;i++){
contDivs[i].style.height=maxHeight + "px";
}} // Run fixheight on page load
window.onload=function(){
if(document.getElementsByTagName){ fixHeight(); }
}// ]]>
</script>
In my case, I always want the center column to define the height for the left & right columns. SO... this means
(1) I need to wrap my center column with <div class="fixheight"></div>.
(2) I need to modify the portion below so that it will write my side columns (wrapped with <div class="sideheight"></div>) to the same height.
Code JavaScript:
// assign all divs the height of the tallest div
for(var i=0;i<contDivs.length;i++){
contDivs[i].style.height=maxHeight + "px";
}
Javascript is not my specialty at all, and I'm hoping to rework this to write the sideheight style instead of fixheight.

I'm using JQuery to write content into an otherwise empty iframe like so:
Code:
$('#ifrmID').contents.find('html').html(htmlContent);
The content is coming from an Ajax request. The content gets used more than once on the page for other purposes which is why I don't simply change the iframe src--I have to do an ajax request regardless so I'm trying to avoid multiple calls.
After I load the content, I need modify the height of the iframe so it fits snuggly around the content.
Calculating the height isn't a problem with the exception that it's not always correct and I think it's because the calculation is happening before images have downloaded.
I don't seem to be able to rely on a `load` or `ready` event to delay the calculation. The load event is the only one that tiggers on a change of iframe content, but it doesn't see the new content.
Code:
$('iframe').each(function () {
$(this).load(function () {
alert($(this).contents().find('html').html());
});
});
This will output '<html><body></body></html>' even though I have successfully inserted different content.
Any suggestions on what I'm doing wrong, or if it's possible to do what I want reliably?
Note that a general JS solution will be appreciated as much as a JQuery one.

I have a column of links that use ajax to load content into the adjacent DIV, and I have used the loadobs function to load the JS and CSS files along with the external file. Now within the external file I have used javascript to create a 3 tab section; when you first load the page it is fine BUT if you navigate away from the page and then try going back and loading the same external page then the tabs stop working and all the content of the tabbed sections stack ontop of one another as though the javacript isnt working?
It is a work in progress but the page I am having the problems on can be found at [url] if you click on the top link in the left hand column called Tara - Female vocalist you will be able to see where the tabs are.

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?

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 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]....

[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'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 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 generate in a js variable some code of tthis kind:
z = '<div id="d1"><div id="d2"><div id="d3"></div><span id="s1"></span></div></div>'
then i write: document.write(z)
obj = document.getElementById('d3')
obj.innerHTML = "some long html content having tags like <h1></h1><h2></h2>"
Then I want to get the height of my 'd3' div. I use obj.offsetHeight with Firefox and it does work, but it Does Not with Internet Explorer. I looked at so many forums and they all say that offsetHeight do find the height, but it's not working in my case. Any ideas why?

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.
