Textarea With Dynamic Width

Jul 23, 2005

This textarea, however, must have a dynamic width, one that "fills the
screen width of any sized screen". Sorry but I cannot fathom how to
do this!

<textarea name="resume" cols="108" rows="29" wrap="physical><?=$resume ?></textarea>

How on earth do I do this? cols="???"

Is there either a client-side solution in HTML or Javascript, or will
I have to use a server-side solution in PHP? I'm completely stuck and
under a Monday AM deadline to come up with a solution.

TextArea Width

Jun 20, 2006

I'm using a third party libray and I can drag a diveand resize it. The
issue is, I have a textarea inside of it and I need to resize the width
of textarea and height of textarea along with it.

I know what the width and height of the div will be when it finishes
dragging (in "px"), so how do I convert the width and height in "px" to
the cols and rows of a textarea?

Find Text Position/width Within Textarea

Jul 30, 2007

I'm really not sure how to go about doing this, so any and all pointers are welcome. What I'd like to do is be able to find the position and width of a word that has been typed inside of a <textarea>, so that I might overlay some absolutely-positioned elements on top, and size them properly. I would really like to be able to do this in the most general case as possible (independent of fonts, font size, size of the textarea, etc.), but as stated any help is welcome.

Jquery :: Dynamic Width On Dropdown Submenu

Jan 3, 2010

I spent way too long writing a buggy and bloated jQuery script that is supposed to allow the sub-menus of a drop-down menu be a dynamic width (i.e. the submenu assumes the width of the widest list item). I am probably missing some base CSS property, surely it cant be this hard? My script I wrote is:

// drop down menu
var setWidth = 2;
var nextSetWidth = 0;
$jQ('.nav li').hover(function(){
var thisList = $jQ(this).parent('ul');
if (thisList.parent('li').length > 0) {
thisList.children('li').each(function(){
var thisSpan = $jQ(this).find('span');
var spanWidth = thisSpan.width();
if (spanWidth > setWidth) {
setWidth = spanWidth;
}});
setWidth = setWidth + 16;
thisList.css('width', setWidth);
}

var nextList = $jQ(this).find('.nav:eq(0)');
if (nextList.parent('li').parent('ul').parent('li').length == 0){
nextList.css('left', '2px');
}

nextList.children('li').each(function(){
var nextThisSpan = $jQ(this).find('span');
var nextSpanWidth = nextThisSpan.width();
if (nextSpanWidth > nextSetWidth) {
nextSetWidth = nextSpanWidth;
}});

nextSetWidth = nextSetWidth + 16;
nextList.css('width', nextSetWidth);
if (nextList.parent('li').parent('ul').parent('li').length > 0){
nextList.css('left', setWidth);
}}, function(){
$jQ(this).find('.nav:eq(0)').css('left','9999em');
setWidth = 2;
nextSetWidth = 0;
});
//End of Drop down menu

The HTML looks something like:
<ul class="nav">
<li><a><span></span></a></li>
<li><a><span></span></a></li>
<li><a><span></span></a>
<ul class="nav">
<li><a><span></span></a></li>
</ul>
</li>
</ul>

JQuery :: Dynamic CSS Padding Based On Element Width?

Oct 21, 2010

I'm currently working on an IE7 CSS fix for a rather large form. Long story short, I have each input wrapped in a div, all in the same class. What I need, is to have each div define a padding-right value that is equal to the width of that div. I'm fairly new to jQuery, so I'm in need of some help with the syntax. Here's what I currently have, but it keeps printing a padding-right value of "0".

$('.form_label').each(function(){
$(this).css('padding-right', function() {
var w = $(this).width();

JQuery :: Dynamic Height / Width Sometime Broken On Page Load?

Aug 28, 2009

I've written a small plugin to serve as a feature rotator and am having one strange problem.You can see some demos of the plugin and documentation here:

http://pbskids.org/pbskidswidgets/carousel.html.The plugin does a number of things that involve reading the width and height of DOM elements and using them to set the width and height of other elements. The problem is that sometimes in Firefox and Safari, when the page loads, the widths and heights of panels in the carousel are fracked.

Reload the page and the problem's fixed. In Safari, I can't get it to happen again on many reloads. In Firefox, though, if I reload repeatedly, I can get the problem to happen again: maybe once every seven or eight times.It looks like something's happening with page loading, but I'm at a loss to diagnose it further: is the script firing before the elements have fully loaded sometimes, and then works on subsequent tries because those elements are in the cache? Also: I've never seen this error in any of the IE versions.

Defining Div Width Equal To Undefined Amount Of Images Total Width?

Oct 4, 2010

let me try to explain better what I'm trying to do. I'm a real newbie I don't know much javascript but I understand more or less the logic behind it... tell me if this solution should work and if you know how to do it please show me. [URL]... I need to make div#photo's width to match the total width measurement of all the images it contains. If you load the page and you don't touch the size, it will work fine... but that's not realistic. If I resize the page, which will happen often on this kind of page (I'm assuming), the whole thing goes haywire (try it, scroll to the last image and resize the page you'll see what I mean). What can I do? Is my idea the right solution? Am I not explaining this clearly enough? Let me know please, I'm desperate. I've been trying to get CSS to do this for me for 3 hours now. Nothing works.

JQuery :: All Images Must Be Resized If Width Exceeds Max Width?

May 5, 2010

I currently have a website where i share thoughts with my friends (some kind of forum) and within this 'forum' people can post pictures they made but most of the time these pictures exceed the max width of my website so my website gets all streched out!So this is what i want: all images on the page must run thru some sort of function which checks if the image image width exceeds the max_width. if it does then the script must calculate how many pixels the current width exceeds the max_width and get this number so that the script does: current_width = current_width - (max_width - current_width)

JQuery :: Resizing Width Depending On $(window).width?

May 18, 2010

I've recently start using Flexigrid (old JQuery grid plugin), and, as you may know, one of the few issue this really good grid plugin got is the lack of liquid layout option. My personal idea to solve the problem is to set the "width" parameter depending on $(window).width. Here is the problem (and here's why i post this question in "General use" and not in "Plugin").

The starting, and working, code is:
$(document).ready(function(){
$("#flex1").flexigrid
(
{

[Code].....

This work fine for me, but I supose it could be done way much elegant... maybe somethin without "IF" that could emulate the "%", like var percentage = $(#div.id).width()*0.XX with the 0.XX picked from an array of percentage, one for each column. Probably I should set up a function... ahhhh, as you may easily see I'm a total beginner with JQuery (and JS in general...)

Set Width Of Item Based Off Combined Width Of Other Elements?

Jun 4, 2011

I am trying to setup a javascript function that sets a div's width based on the combined width of the li's with the name "navItem". The problems I have been running into when trying to define the width of the li's is that they do not have a width defined in css. Can anyone help me out with this? The javascript function setWindow is suppose to show the div loginWindow and set the width of it.

Code:
<div id="topNav">
<ul>
<li><img src="<?php print $site->folder['images']['header']; ?>topmenu_left.jpg" border="0" alt="" /></li>
<li name="navItem"><a href="<? print $site->url['about']; ?>">About Us</a></li>
<li name="navItem"><a onmouseover="setWindow('loginWindow');" href="<? print $site->url['billing']; ?>">Client Services</a></li>

Onclick Change Div.width Flash.width ?

Sep 10, 2009

I need a code that when a button or image is clicked then a div's width and height are changed.

Ive managed to get a few codes that does this, but the real problem is that, the contents of the div is an embedded flash file and i thought that by setting the flash width and height to 100% then the flash would fit to the new size of the div, but it just didnt work.

I need a code that when a button is clicked then the div's and the flash's width and height are changed.

please have a look at the temp website latinunit net / temp / , you will understand where im coming from.

on the right hand side i have a flash chat in a div , div is controled by a script that allows it to follow the scrollers up and down.

My goal is to add a little button in the same div that says expand or maximise so when clicked the the div expands aswell as the flash file.

Set The Width Of A Div To Be The Same Width Of The Image Inside The Div

Nov 5, 2011

I want to set the width of a div to be the same width of the image inside the div.The following code works great. But...The images are different widths, so both wrappers are set to the width of the first image. Without having to add an ID to each wrapper or image, can the wrapper width be set to the image width using the name of the image as the unique identifier?

jQuery:
$(document).ready(function(){
var newWidth = $('div.wrapper img').attr('width');
$('div.wrapper').width(newWidth);
});

HTML:

<div class="wrapper">
<p><img src="image1.jpg" width="200" /><br />
Caption</p>
</div>
