I forget how to do this. Maybe somebody can point me to a decent tutorial. But I'm looking to grab the width of an <li>, including padding and margins that doesn't have a set width, and has one of 'auto' or 0.

View 5 Replies View RelatedI have generated menus from an XML file. The XML also defines sub menus that are to open when the mouse is over any one of the menus.The menus are div tags with text in them. The location of each is based on the order that they added in and the width of the text with some padding.When the users mouse moves over the menu item it should pop up a sub menu at a relative position to the menu item.How do I get that position and width of the menu the user is over if it has never been set explicitly? Is there a way or not? If not what is the best solution for something like this?
View 1 Replies View RelatedI'm trying to learn a bit more Javascript/jQuery and I want to write a bit of code to adjust 'background-position' based on the width of the 'background-image'. So my short question is, How can I find the width of a background image using Javascript/jQuery? For those who are interested in what I'm doing (or trying): I have a list where each item has a background image along with some text. I want the images to all centrally-align along a vertical axis in a space to the left of the text. Problem is, the images are different widths, so I want to use jQuery to find their widths and calculate the appropriate background-position.

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.
View 3 Replies View RelatedI've been trying the find the (x,y) co-ordinates of an element. I've been using;
document.getElementById(element).style.top
document.getElementById(element).style.left
However this doesn't always work in my script. Now, I've googled how to find the position of an element. And come accross many scripts which supposedly all find the position of any object. Some are very long scripts and some are very short all using a variety of methods. Incidently none of which work, they all return (0,0).

I'm fairly new to jquery and I've been stumped on this one for a day now. I'm creating a lighbox type photo gallery on a page. The box is simply a hidden div that is displayed when the user clicks a link. When the link is clicked to launch a gallery I'm using the .load() function to grab another page and load it into the hidden div which is now displayed.
The code looks like this $('#galleryBox').load('boxModal.php?ID=' + ID)); The issue I'm having is after I load up the gallery box with boxModal.php.. I want to be able to respond to the click or mouseover event of the images that have loaded in that box. But I can't seem to find the images in the DOM. Is it possible to add event handlers to images loaded using the .load() function?
I have a calendar in which each day is a separate div, and all these are within a container div #cal. When a user mouses over one of the days, I want to figure out the index number of that day's div within #cal. Simplified example:
<div id="cal">
<div onmouseover="findIt()" id="nov1">1</div>
<div onmouseover="findIt()" id="nov2">2</div>
<div onmouseover="findIt()" id="nov3">3</div>
</div>
I can easily get the index of #nov2 from Firebug if I do this in the console:
$('#cal div').index($('#nov2')
But, I can't figure out how to write a function so that I don't need to assign an id to each day div. I'd like to be able to just take "this" from the moused-over div, and pass that to a function that can turn it into the needed index.
I am working on a little project with fullcalendar but while writing some callback functions stumbled upon an issue: Fullcalendar generates html that looks like this: <a><span></span><span></span><span></span></a>.
Now there is an eventClick callback that is fired when clicking on that <a> element. However, in that callback I would like to know which <span> element was clicked.
Since jQuery parses the entire dom first, is there any efficiency gain in directing it via the entire CSS chain rather than directly to an ID? That is, if I have a Div with an ID of "foo" and it contains a P with an ID of "bar", is there any speed advantage in using $(div#foo p#bar) as opposed to just using $(p#bar), assuming jQuery would be more efficient if it had both indexes?

Basically, I'm looking for a way to find a list element that has a ul child, and then hide or show that ul. What I have here doesn't seem to be working.
I'm pretty new to jQuery and this is giving me a lot of trouble! I found some code jQuery code to give me a great start but I can't get the logic to where I need it to be. Here is what I have:
$(document).ready(function(){
$('p', 'body')
.andSelf()
[code]....
What would be the easier way to do this? For each of the list elements I want to check how many image elements are inside each, and do something with the one that has only one image.
<ul>
<li>
<img src="" />
[code]....
For example, if we press tab in a page and the tab finds an A Link and then we press enter, it will be like Clicking in the link. I would like to know how do I do to make that kind of selection in my element, cause I wanna make a function to select the item so the user when pressing enter it opens the <a> link.
View 3 Replies View RelatedI want to call stop() on an element animated with animate() based on a user hover. I also want to figure out how close to complete the animation was when the user hovered.
In a simple case I would just compare the animated element property's current value (ie height) to its target value, but in this case I'm creating a generic animator and don't actually know (without a ton of otherwise unnecessary housekeeping) what properties are being animated.

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'd like to set the div width equal to the image width. Here's what I can think of [code]...
View 3 Replies View RelatedI 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:

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 have got the following CSS-Box, with those properties in my styles.css:
.panorama {

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 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’}
