Jquery :: Get Width From The Center Of An Element To The Edge Of Viewport?
Apr 9, 2010
Essentially the idea is to make Element-B and Element-C to cover the area horizontally starting from center of Element-A and ending at the edge of viewport.So, I guess i want to get the distance value from the center of Element-A to the edge of viewport
Additional notes:
Element-A doesnt have static position or size.
Element-B and Element-C verticalposition or height is
irrelevant.
I was thinking something like this:Calculate width of Element-A and divide it by two ( Or just get half the width if theres a way. )
Get the distance from the edge of Element-A to the edge of Viewport Add up these calculated values.Of course unless theres way to get that this width straight up )I was trying to look for a way to do list item 2.

write a PHP script that detects the user's viewport width, and I am guessing stores this in a variable, then checks if it is less than or equal to 1024px using an if statement and if so attaches a certain stylesheet, lets say alternative.CSS, but in the else part of the statement; therefore, if the viewport width is greater than 1024px, it attaches or links default.css

I have 2000px width images that I want to be centered in a 100% width slideshow. I basically want my images to cover the entire width of the page, and also be centered.
Nothing has worked for me. No matter what I do, my images get pushed to the right and far off from the center.

Imagine a mess of div-elements nested inside each other
some relative, some absolute.
Some of them grows when their children grows...
And at some point, I want the x-coordinate of the bottom
edge of the element that is lowest down on the page.
Of course I need to support the most popular UAs on each
major platform (Not NS4.x)
(In my particular case, I'm only interested in div elements)...
Any hints on this?

Is there a jQuery function that can cause an element to slide down as in fly from an edge of a screen to the location that it is supposed to be at? The slideDown();function causes an element to start at the top of the container the element it is applied to and then roll down. I guess what I am looking for is something that would on an event slide from an edge of a screen or browser window to where it is supposed to go? Are there any functions or transitions like that?

Is the next jQuery code the best way to decrease an elements width?[code]I tried using the next code:[code]but that's not working, also not with '-20'.Maybe it's an idea to add this functionality? It's is already used in the .animate() function for changing the position of an element.

I need to find out how to center an element on a form that scrolls. I have code (below) that displays a dialog, but I can't figure out how to make sure the dialog is centered on the page when the dialog displays as the user scrolls down the page. The dialog is displayed from a click on a href tag. I thought I could get the x,y coordinates where the href was click, but can't figure out how to center since the href can be at either the upper or low end of the page when it shown.
<script type="text/javascript">
var xCoord;
var yCoord;
$(document).ready(function () {
// if user clicked on button, the overlay layer or the dialogbox, close the dialog
$('a.btn-ok, #dialog-overlay, #dialog-box').click(function () {
[Code]...

I'm having a really hard time trying to solve a problem. I have a container DIV aligned center that holds an image. The container is max 940 X 609. The image is set to be 100% width and height.
The objective is to have the container shrink as the user resizes the browser up until a minimum size - say, 400 X 259. I also need the container to stay centered with consistent margins on the right and left.

'm having the worst time trying to figure out the math to this problem.have the viewport, offset of the div, amount scrolled, dimensions of the div, and dimensions of the element. But, I can't get the element centered.granted if the div was off screen, or there wasn't enough room for the element to exist, the element would be placed in the nearest position.so, right now I'm just trying to center the element vertically.Here are some variables
viewport.height = 870
scroll.top = 1200
div.offset.top = 550
[code]....

I'm currently working on a webpage and I seem to have a small problem.
I have a few div's with dynamic content but I can't seem to get the floating right...
So this is what I want, [url]
And this is what I got, [url]
I can't get a width to the <p> element since it's also used in other divs with other widths etc.
So now I was wondering if it would be possible to have jQuery solve this for me.
The <p> element should be 350px width when there is no image inside the div where to <p> is in.

I have got the following CSS-Box, with those properties in my styles.css:
.panorama {
float:left;
overflow:hidden;
}
[Code]....
But when I want to read out this information afterwards, my function doesnt work:
console.log($('.panorama').css("width")); This delivers me 0px.
Why doesnt it bring me the 1641px?

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();
[code]....

I have some one page whose div elements are aligned by JavaScript. The JavaScript just check a set of div elements to find the max offsetWidth, then set all div elements' width to be the max offsetWidth. It works perfect in most browsers and locales, but it fails on french-France in Firefox on Mac. In this case, the content of div wraps.
<div id="divFoo">
Heure de début :
</div>
for above HTML, below code report "79".
javascript:alert(document.getElementById('divFoo').offsetWidth);
but below code report "79.1333px".
javascript:alert(window.getComputedStyle(document.getElementById('divFoo'),null).width))
The gap between 79.1333 and 79 makes incorrect width set to inline style.I used to thought that offsetWidth and width should always be integer. Is there any way to make offsetWidth round correctly?

I'd like to set the div width equal to the image width. Here's what I can think of:
Code:
<script type="text/javascript">
window.onload = function ()
{
document.getElementById('foo').style.width = document.getElementById('bar').width + 'px';
}
</script>
<div id="foo" style="background:red;"><img id="bar" src="image.jpg"></div>
It seems to be working, but I'm not sure if it's correct coding.

I have problem with reading div width, sometimes, for this same div element, jquery returns width of 800 (which is correct), but then sometimes, it returns 93(which is not correct).
Here's the html (part of it):
Code:
And here jquery function:
Code:
This line is the problem. Sometimes, it says width of that div element is 800, sometimes 93. I put border around div, and i can clearly see it really hs width of 800, but sometimes, i still says (firebug) that width is 93. there is the image inside this div.

I'm a new Javascript coder; it's still pretty easy for me to get snagged on stuff. Anyways, I had a question for a specific project I've been trying to figure out.
I have an element set with CSS to a width of 160px. What I want is a way for users to the site to drag a slider back and forth to set the width of the button. Some sort of smooth animation while this is happening would also be nice. I'd also like a way to set a max width on the element.
So, can this be done? I'm guessing it would use jQuery, but I don't really know.

How can I change the height and width of an element with Javascript? I have tried and so far I can only change either the width or height but not both, doing something like this…
Code:
<HTML>
<HEAD>
<script type = "text/javascript">
function changeSize(){document.getElementById('test').style.height = '200'}
[code]....
And this works fine but if I try to change both height and width it doesn’t work. Doing something like this doesn’t work
Code:
function changeSize(){document.getElementById('test').style.height = '200' width=’200’}
