Grab Center Column Height And Force Same Size On Left One?

Jan 17, 2009

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.

Force Column Width In A Table?

Jul 20, 2005

I want to ensure one column in a table is always the same number of pixels
wide no matter what the screen resolution is set to on the visitors PC - the
other two columns can wrap away top their hearts content.

How do I do this please? The code below doesn't do it.

<table border="1" width="100%">
<tr>
<td width="180" valign="top">&nbsp;</td>
<td width="*" valign="top">&nbsp;</td>
<td width="*" valign="top">&nbsp</td>
</tr>
</table>

Force Webpage To Be Minimized To A Set Size?

Jan 12, 2010

When users manually minimize the website window I need the window to minimize up to a certain point and go no further. for example I need the minimum window size to stop at 800 x 600 and get stuck there even if a user tries to minimize it further.

The code that I am trying to play around with is the following with onresize function but I am not sure how to make it give me what I need.

Code:
<head>
<script>
function OnResizeDocument () {
alert ("The size of the window has changed.");

Force Reload After User Changes Browser Size

Jul 20, 2005

I'm using a little javascript to help my site's design to fit the visitor's entire browser window.
Everything works great apart from one problem. If a visitor first loads the page and the browser isn't maximised, the page loads correctly BUT if the visitor then proceeds to maximize the browser, the page is still set for the minimised browser. This condition stays until the visitor goes to another section of the site or refreshes the page. When this happens, the page again loads correctly.

I would like to force a page reload whenever the browser is minimizedmaximized or is in any other way changed size. How can I do this?

Make A Column Height Match Another?

Jul 26, 2010

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?

JQuery :: Get Matching Column Height With Divs ?

May 14, 2009

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?

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?

JS Script To Center Page Briefly Shifts Page To Left Before Centering?

Oct 26, 2009

I have absolutely positioned left-aligned elements that I'm attempting to center with javascript.The page briefly shifts to the left when the page is loaded before it centers the page.(I realize that this goal could be achieved with CSS alone but I am hoping for a cure for this javascript solution for now.)The javascript that I'm using is common.js, the onload command is positionPage(); and the div is DivLayout.I don't know if I need to adjust the div, javascript or both.how I can correct the shifting issue?Here is the link to view my issue: http:/tiny.cc/test176

String.prototype.trim = function() { return this.replace(/^s+|s+$/, ''); };[code]...........

JQuery :: JqModal - Auto-size And Auto-center The Modal On The Page?

Aug 29, 2009

Using the very basic jqModal example, isn't it supposed to auto size and auto center the modal on the page? I placed a table that was wider than the modal's default settings and it's off the page and does not create scroll bars on the page to see the hidden section of the modal.

The default class is

Now, I know I can change the width of the modal but what about the positioning?

Edit An External CSS - Height And Size Attributes Of Elements On The Page

Nov 12, 2011

I'm working on my personal website [URL] and I'm trying to use Javascript to edit some of the height and size attributes of elements on the page, based on the user's window size. I've got the code that gets the window size working, and calculates what I want to set as the "boxSize" but the part that goes into the external CSS to change the values is not working. "boxSize" is a variable that holds just a number. I'm not sure if it's really stored as a number or a string, but I don't think that's supposed to affect anything.

I'm just putting in the relevant part of the code right where it's failing. I figured out (using alert() statements) that the script is definitely working right up until before the two lines given, and failing to get through them.

Accessibility: Possible To Determine Browser-chosen Point Size Of A Relative Font-size?

Jul 23, 2005

All my font-sizes are set as relative sizes in CSS (large, medium, small,
x-small, etc). Let's say something is set in CSS to be xx-large, but a
visually impaired user wants it displayed even bigger. Can a script
determine an element's absolute size, *as it is being rendered by the
browser*, and then increment the element's font-size in absolute terms?

Resizing DIV - Makeweb Page That Adapts To Size Of Your Browser Size When Maximized

Jul 19, 2010

I'm attempting to make a web page that adapts to the size of your browser size when it maximized. Because I'm only 15 I'm not such a great programmer or coder. I've done my best with the resources I have though (Fluent in Lua and a natural ability to pick languages syntax up quickly)

Here is what I have so far, it doesn't work and it is starting to puzzle me. As it seems correct as I look at it. I'm sorry if this question show my ignorance. I try my best to hide it.

Some of it is Copy pasted from sources on Google. But only for educational purposes, I learn off reading, examining and testing out snippets.

I'm basically trying to get the max size of the window and resize the div accordingly.

Apr 28, 2011

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?

Limit File Size Or Request Size

May 27, 2010

I developed a web application and it is working fine, except for one issue. The application includes uploading files from a JSP to my servlet, and the issue is that i would like to have a limit for the uploaded files on the client side (before actually uploading it).

I investigated alot and found some ways like changing my JSPs to PHPs, which is not feasable for my application. I would also like to add that using the Flash component ("<object>") for uploading is not feasable also at this time. Using ActiveX does not work also (for some security issues in javascript, it can not access the system information, also ActiveX works only on IE).

I would like to add that I have my application running on Oracle application Server, JSPs for displaying the forms, MultiPart Java API for getting the form input values and files to my servlet and everything is developed in JAVA.

Either by limiting the file size or the limiting the whole request size sent to the servlet.
