JQuery :: Can't Retrieve Style Properties From DOM
Oct 1, 2009
I'm not sure this is the right group to post to, I've just found this group.I notice the old alt.dhtml group has been murdered, overwhelmed by spam. On my page: [URL] I am trying to get an element's style.top, style.marginTop, and backgroundColor. I can successfully do getElementById( ) on the element, but I can't get any settings from the element. If you bring up the page, all of this stuff is supposed to display in a header-like line just under the small banner. I can see that the doc's scrollTop has been retrieved OK (it wiggles if you move the vertical scroll bar) but all the other stuff is MIA. What am I doing wrong that I can't get this element's style properties? In the source, the function 'scroll(),' which is trying to read these
properties, is at line 52.

I thought I'd try to begin with the accordion and tab, but I have had no success yet. I must be missing something simple. Here is the first test page:[code]Instead of getting tabs, I get my pages (generated by cgi perl scripts) displayed in tiny little scrollboxes at the top left.Equally bad, Firefox is telling me, in the error console, that jQuery.Tabs is undefined.FireFox doesn't like the filter and zoom properties in your style sheet.So, then, what do I need to do to get the tabs to work in the first instance. And then, how do I modify it to use an Accordion to display the same material. Are there any issues I need to be aware of when I start having my perl scripts (using predominantly the Perl packagesCGI and CGI::Session)create these pages?As far as possible, I am trying to keep this all valid HTML5, so that I can eventually make this interface mobile device friendly.

I am working on a little javascript project, and I need to get an arbitrary element's style information.
For instance, I want a method that you can pass a reference to an object, and for instance, find the current css height property that applies to it, no matter where it was declared. I don't mind it returning a null value if it wasn't set anywhere, but if it's coming from some css class or some css id or some locally defined style, I want to know what is being expressed.
If I just try el.style.height, it only lets you know what the height is if it was explicitly defined in the style tag.

Using Javascript I know you can create elements on the page, but is it possible to create properties within the Style element?
For instance, I want to create the following CSS style:
Code:
.className
{
background-color: #9cf;
border-top: 2pt solid #000;
border-right: 1pt solid #000;
border-bottom: 1pt solid #000;
border-left: 1pt solid #000;
}
Is this possible using the DOM, or will I need to export all of my styles in one long text string and replace the Style tags innerHTML?

I was originally under the impression that css style properties could
be accessed/ listed since they exsisted as an array somewhere.
Is this just flat out wrong?
To illustrate - I guess I thought something like this could be used to
list available/ or set properties, or in this example the first
property. Is this just a fantasy? Or how does this work, at this level
or for document objects even?
//assuming <div id="menu"></div> exisists and hs styles applied....
document.write(document.getElementById('menu').sty le[0]);
//of course this is wrong...

I would like to create a function that will change the colour of a button when clicked then change it back at the end of the function. It works by capturing the backgroun color an then storing it as a variable. However it refuses to capture the original background color if the style is set via an external CSS style sheet. It only works if i set the style via the element markup. Am i doing something wrong and is there any way of capturing the style set by a external stylesheet?
Code:
function myFunction(el)
{

I know the atomic way to set style properties of a DOM element like
Is there any way to set multiple properties in the same time? I'd like to spare some cpu time...
I assume if I use framework like JQuery to set more style props at once that call will be interpreted to the atomic way I described above...
Am I right with this guess?

how to add extra properties to html elements as I was storing data in html attributes. After looking at some others code including Raphael and this addEvent code. [URL] They seem to treat objects just like an array. obj[property] = value; This would have been extremely helpful to know previously as I have needed to be able to include variables in property names - but have resorted to making the whole thing a string and calling exec() on it.

My understanding had been that $.css("width") would return the original user selected style, eg "100%" or "10em", and $.width() returned the computed width, always in "px". Not so, following the code through for .css(), it calls something called getComputedStyle and the only difference between the two functions turns out to be a post-fix of "px" on the .css() result - not very useful. I need to know whether my user has called me with a proportional dimension, or a fixed one. How to tell with jQuery?

This is probably quite a simple problem but I can't figure out the answer. I'm working on a site that has news stories and events coming in. What I would like is to have the news stories to be styled with squares and events with discs for instance. I might be able to change the actual plug-in so the CSS affects this change, but I just wondered how I could change the list-style-type with jQuery.

I wrote this simple snippet to animate a listitem from an unordered list. Here it is:
function OnLoad() {
$('#navigation').mouseover(function() {
$(this).find('li').stop(true, true).effect("pulsate", { times:2 }, 150);
});
So I have a div with id "navigation" which contains an <ul>, and the <ul> has several <li> items.What I want to do is to animate the <li> items as i rollover them.My question is , how can I only animate the current <li> I rollover, because right now when I rollover one, all <li> items animate.

I'm completely new to jQuery and Javascript but I have extensive (10+ years) with Flash and Actionscript.
I want to create a dyanmic tree menu, but I wonder what is the best way to get the data from a MySql database.
Honestly, compared to AS3, the implementation of XML seems very primitive... In As3 you simply move around the xml as if those were objects using E4X. This way: MyXML.myNode.myChild[3].text()
So I wonder, what is the best way to work with data from the DDBB? Is there a better way of using XML with jQuery? Maybe JSON?
How should I approach this?
