In the example below it appears JavaScript can't read a style property if it's not specifically defined with JavaScript before, ie you can't get a value in this way:
Is there a way to read such style properties directly?
Code:
Below is the IDL definition of the HTMLOptionElement.
interface HTMLOptionElement : HTMLElement {
readonly attribute HTMLFormElement form;
attribute boolean defaultSelected;
readonly attribute DOMString text;
attribute long index;
attribute boolean disabled;
attribute DOMString label;
readonly attribute boolean selected;
attribute DOMString value;
};
You will notice that the 'text' and 'selected' properties are marked as
read-only. This adds an interesting dilemma: how do you go about
programatically modifying these properties, especially considering the
need to assign to 'text' when creating a new object? Would you add a text
node, as you find in HTML, to represent the text displayed? If that is the
correct approach, it still leaves 'selected' inaccessible[1].
Something that I did notice is that the ECMAScript bindingsdon't mark any
properties as read-only, and assigning to 'text' is possible, certainly in
Opera. Is that because there is no concept of read-only, so the browser
can choose to ignore assignments, or some other reason?
I've got this JavaScript code that I'm using to play audio on my site made specifically for iPhones, iPods, and whatnot. However, my only problem is, that I can only pick one audio file to play from, no matter what. Can someone tell me what I'm doing wrong? I really need this specific code cause it allows me to play audio without going into the Media Player on the iPhone and iPod.
Here's what I have in the head section:
And the body:
And now to actually play the audio:
I can play audio fine, but I'm only limited to one audio file per page. Is there anyway around this??
I need to write an extensive online circuit design website with lots of drag/drop.
What is the best JavaScript framework for drag/drop specifically?
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.

I know it's something stupid I'm doing but I can't figure it out. Essentially I'm trying to load two objects with URLs with two websites that can be loaded(displayed) and unloaded(hidden) at the click of a button.
I've spent an hour trying to debug this and I'm at my whits end! I'm doing this with changing the width and height of the divs that contain the objects that will load the websites. But, in Firefox I get an error in the error console saying : loadUnload is not defined. why? code...
I call submit() and get a javascript error 'Submit not defined' in Firefox..
My very expensive javascript Bible assures me its built in ..so where oh
where have I FSCKED up?
Its all within a form..that all works but I haven't yet defined a submit
button, because ultimately I want a clickable image with dreadful
graphics emblazoned on it..or something.
Heres the snippet..

I am working with a dice game that is going to roll three dices and it works. Now that I am going to count the hits, my Firebug says that: tarning1 is not defined. What have I done wrong? Here is my code:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
[code]....
This is an admittedly convoluted script, so I'm not surprised it's a bit buggy.Basically, I'm arranging several hundred small divs on a page. This code writes each of them onload, and checks urlArray to see if the specific div being written has a function attached to it, then enables onmouseover/onmouseout hand pointer/default pointers to it, and, of course, runs the function onclick.
var urlArray = ["main", "none", "none", "none", ... (snip) ]
var i = 0;
function writeDivs(){[code]....
The script as it appears here runs great in chrome, but Firefox tells me that "main" is undefined whenever I click or roll over the div, and IE says "object expected" when I click."main" is the name of a function defined in an external js file (though pasting the function into the main document doesn't do anything).In fact, the whole of the above script may not even be relevant, since the following doesn't work either:
document.write("<div class='posDiv' id='div"+i+"' onclick='javascript:main()' >"+textArray[i]+"</div>");
I think I have a simple problem, but unfortunately my JS skills are such that even something like this goes over my head. :/I have a site: buypermasetinks.c0m <-- I guess I'm not allowed to post real links yetOn the product pages, it uses JS to calculate the pricing of the different inks, based on their sizes.

I've tried to add a Lightbox script to an already existing page that already had a javascript feature in it. Now I know that there's no limit to the number of scripts you can run simultaneously, but when I added the lightbox feauture, my compiler gave me the following error:
$ is not defined
his.elements = $(this.options.thumb...lements(this.options.itemsSelector);
This line of code was part of the original source code of the page, and hadn't been a problem before I added the Lightbox code. Why is $ undefined all of a sudden and where can I find a solution for this? Could someone point me in the right direction here? I'm not exactly a novice(yet) when it comes to Javascript and this project was due yesterday.
URL...This is my site and there are two dropdown menus on right side of screen under PRICE: $185.00 title when you open this dropdown it shows "Not defined" option automatically.

It seems that this code

executes whether myFn is defined or not. When it is not, a JS error

I came accross this weird problem that I just can't figure out. First
of all, here is a link to the script:
The following line

I find this surprising, given that Submit descends from Object,
and the constructor 'new Object("value")' is well defined...

I was working on a site for A/B Testing and on the new page I was using to test with I installed "Nivo Slider". Everything looks and works great the only problem is when I change the region from US to Canada, that is when I begin to see errors like these: [url]
What you should be seeing is that each of those long columns are cut shorter to make everything look uniform but it seems when I uploaded the jQuery something is now off and causing things to go crazy.
Site A: [url] (how the Canada site should look as well)
Site B: [url] (testing site)
Site C:[url] (Canada site)
Again, I installed Nivo slider and do see an error related to it but dont think it is the problem necessarily. I dont know you guys would no better than me. I originally had a problem with it but did the no conflict thing and changed the $() to jQuery()
