Set Variable Width On Element With Slider?
Aug 7, 2011
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.

I am using Ben Alman's JQuery resize plugin in order to obtain the varying computed width of an element when the window is resized (the element in question is a page wrapper that exhibits the expand-to-fit behavior of a block box, and it's computed width is obviously influenced by the resizing of the window. Essentially, what I need to be able to do, is to reference a variable that is defined in a .resize() function ('width_page') in a seperate .each() function.
[Code]...
I now understand that variables can't cross boundaries like in the example above, which leaves me a little stuck. I also understand that this is specific to the context of the .resize() function, and that it can't be taken out of it without using an element selector. Is there some way I can call the .resize() function in my .each() function?

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'm working on a page that needs to do some calculations based on values that the user inputs via sliders. I can get the values selected to display in a text box below the slider, but I also need to store the value as a variable for use in calculations.

Ive never heard of this being done, but currently ive got a div which sits in the center of my screen. The div is about 80% wdith so there is a 10% gap on the left and 10% gap on the right. However, I want the gap on the top and bottom of my div to be the same as my gap on the left and right.
I need to somehow capture the pixel value for the gap on the left and right, store it in a variable and then use this number in my css for the top and bottom gap.

I created that function for an image slider:
$(document).ready(function(){
$("#gallery").click(function(){
$(this).find("li.third").fadeOut(800).removeClass("third").next().addClass("third").fadeIn(800);
$(this).find("li.second").fadeOut(800).removeClass("second").next().addClass("second").fadeIn(800);
$(this).find("li.first").next().addClass("first").fadeIn(800); $($(this).find("li.first")[0]).removeAttr("class").hide().appendTo($(this)).fadeIn(800);
});
});
Actually I want to fade in the first picture first. Than the second and at the end the third. To achieve that I changed the order of these following three lines:
$(this).find("li.first").next().addClass("first").fadeIn(800);
$(this).find("li.second").fadeOut(800).removeClass("second").next().addClass("second").fadeIn(800);
$(this).find("li.third").fadeOut(800).removeClass("third").next().addClass("third").fadeIn(800);Unfortunately it doesn't work.

Many slider solutions available but they have parameter that forces same delay for display of each element in the slideshow. I'm looking for existing code that:
(1) would display the contents of a div, that is, HTML plus img, as element in slideshow
(2) automatically progresses to next element in slideshow unless paused by mouseover
(3) each part of the slideshow would have its own delay to determine viewing time
(4) FWD and BACK ability for user to interrupt sequence and move along manually
(5) wrap-around at end to resume at begin
Many snips of code out there do everything except (3) since they set one delay that applies to all elements in the slideshow instance, do not support individual delays for each part of the slideshow.

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 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 am trying to access the width variable from my main page. Within the imageinfo.js script functions I can alert() the width value which returns 1024. But I can't seem to pass this variable to my main page or access it directly so that I can use document.write() to write the variable on the page. Whenever I try to call the 'width' variable directly from the main page I get undefined. How can I access this variable? However, with the test code below, I was able to get ducument.write() to write the 'width' variable on the page but now the page doesn't stop loading - there's an endless loop in the code...
Code:
BinaryAjax(url,function(http) {findEXIFinJPEG(http.binaryResponse);test(width)},null,useRange ? [0, Range] : null);
Main page
Code:
<html>
<head>
<script>
function test(width){
document.write('Image Width = ' + width)
} </script>
<script type="text/javascript" src="binaryajax.js"></script>
<script type="text/javascript" src="imageinfo.js"></script>
</head>
<body>
<script type="text/javascript">readFileData('image.jpg')</script>
</body>
</html>
Imageinfo script - This script uses the binaryajax script found below.
Code:

.panorama {
float:left;
overflow:hidden;

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?

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’}

Code:

var width=$(this).attr('width');
var height=$(this).attr('height');
[code]...
I'm trying to do something like above, where I pass the width and height into the Dialog box but it doesn't take the variable.It only works if I put an actual number here instead of a variable.
$('#dialog').dialog('option', 'width', width);

I have the following DIV, that I need to position in the center of the page, I have the following code, but you can see the div is not exactly center, space I have from the top is not the same I have in the bottom, the space I have from bot side is the same.I was wandering also if I can do this dynamically, meaning the div will receive the width and height in run time, and them I will send the values to my method "centerObj" (How I can get the height and width of the div element.

<head>
<script>[code]....

I'm having an issue getting the height and width of DIV elements that have resized themselves to fit their content.
Note: I do not have a problem getting the height and width of DIV elements that I have set using Javascript. The probel is that this value appears to stick. I.e. the height is set to 150px, then the content is changed and the DIV cosumes as much height as is required (clearly more than 150px), however analysing the DOM indicates that the height is the same (though it is clearly not).
I want to know how to get hold of the 'actual' size of a DIV element that is manipulated by the content of the DIV.
I am also interested in a solution that works in IE and Firefox (at least).

I didn't see this as an option, so I decided to give it a try on my own. I was able to add some lines of code (shown with the > in the margin below) to the jquery.cycle.js script to read in the width of each image and center the slide within the slideshow container // set position and zIndex on all the slides

My client wants a ticker, only with client logos. I've found several scripts which are cool, though no one is precisely what I'm after. Company logos vary in their proportions. I'd like ideally a script able to continuously horizontally animate images of the same height, but with variable widths. Found plenty of scripts moving same width images left/right, or using a carrier (table/div/layer) to contain a set of variable width images - the latter leads to blank moments my client doesn't like while the carrier is repositioned.
I'm very intrigued as to why this doesn't seem to have been done and wonder if there's a reason. Is the computation needed in passing widths in a variable to a move function too much for the client-side? I don't want to waste my time wading into repurposing a script for this if it's not viable as I can't pass that cost on to the client, you see. I'd rather bail and do it using Flash.

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.

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]....
