Why Is My BackgroundColor An Empty String ?
Feb 8, 2010
I'm trying to compare a <div> background color with another color. However, on FireBug, I noticed that my <div> doesn't have a background color code in it (I placed document.getElementById(o) on watch), even though I have already specified on my css. As a result, I'm comparing an empty string with another color code. Why is this so ?
Javascript:
function highlight(o) {
var color1;
color1 = document.getElementById(o).style.backgroundColor;[code].....

i have a problem dealing with an xmlhttprequest with the POST method: i receive a string from a java applet in my page and i want to use this string as a post parameter to send an xmlhttprequest, but once i send the request the string becomes empty. i put some debug alert before invoking the send method and they show the string properly. the string comes from a new String(byte[]) in java, so i thought maybe there's somethinig related to the charset?

So I'm having some issue with an ajax call I'm making. The success always returns an empty string no matter if what the php function returns. It seems that looking in firebug the function is called and I've tested it by sending myself an email. It just happens that it is always an empty string. And I am very confused because I developed it on my local server and it worked just fine.

I have this image gallery in which clients should be able to determine the order in which their images are shown. The sortable part works. Then I want to pass the new order to the next page called act_writeneworder.cfm (i am using coldfusion)
I just started with jQuery and it is driving me nuts:-) Each time I think I am having it well i am testing and the variable passed through gives an empty string.
My code:
<script type="text/javascript">
$(function() {
$( "#ulsortable" ).sortable();
});

I have a form with an id "modClassForm" when I try:$("#modClassForm").serialize() it returns an empty string ("") When I get the action attribute it's right so it is the form I was expecting. When I do the following:
$("#modClassForm input").val()
it returns "retret" (the contents of the input element in that form). So what is doing this? The only thing I can think of is that this form is loaded from ajax and then placed in the page using the .html(htmlString) method which is rather core to my design. This works in a whole lot of other browsers (IE 9, FF 6-8, Chrome 13-15 and Safari 5). So I know I could try to serialize the fields myself, but the form content has two modes and I'd have to construct a fairly large string and I'm not sure about encoding. Is there any other way to make serialize work? Some way to get it to recognize the contents of the form?

I am running the scripts below which should return a string containing a URL.So far, it cannot find the form contents in Firefox, but displays the non-dynamic data such as ?Location=. It won't work at all in IE.

Just a quick one here I want a regular expression that tests a string to find out if not empty. I am currently using /^[a-zA-Z0-9]+$/ which allows all alphanumeric characters, however unfortunately does not allow white space. As I am trying to use the RE for a form name input and I don't wish to separate first and last name, I want to allow users to enter their full name including spaces. Can anyone tell me an RE that allows all alphanumeric characters and white space in a string but does not allow an empty string

When I set the background colour of an element using
tdRef.style.backgroundColor and then read it back, Firefox always
gives rgb(r, g, b) regardless of whether I've used rgb(...) or #rrggbb
to set it.
If I use tdRef.bgColor to set/read the value, I always get #rrggbb
regardless of whether I've used rgb(...) or #rrggbb.
IE, on the other hand, when using style.backgroundColor reports back in
whatever format was used (either rgb(...) or #rrggbb), but, like
Firefox, always gives #rrggbb for the bgColor method.
My question is which method is most consistent across various browsers?
I want to use style.backgroundColor (since some browsers don't support
bgColor, I guess it's a legacy from the ver 4 browser days). If I
decide to use rgb(...), is it consistently supported by other browsers
or do some report in #rrggbb regardless? Code:

I have written a javascript version of tetris and at every 10th cleared line, I change the body background color more towards red. However, the page only seems to update parts of the background. It is only after min/maxing the window or otherwise forcing a redraw that the whole page background is actually updated to the correct color.
Any idea why this is and if/how this can be fixed?
This line works as expected, but it may be relevant to highlight.
document.body.style.backgroundColor = "rgb(255," +GB+ "," +GB+ ")";

I want to get the colour in HEX format using "thing.style.backgroundColor". Like "#FFFFFF" or whatever. IE gives this but FF gives it as "rgb(0,0,0)" format.
Is there a simple function/method of getting it as hex? (or a conversion function)

I need help with an IE8 problem. I want to give as many facts as possible.
Reference: [url]
I have already banned less than IE8 from my site but have the following problem with IE8 only (works on Mac and Win in these"allowed" browsers:Safari 5+, Chrome, FF 3.5+ and Opera 10+):
I use the backgroundPosition setter / getter extensively in this animation-extensive site.
But it breaks in IE8.
I did hack this as the only way I could get IE8 to work in a frame animation algorithm, noting that I have to test for browser and version (ugh) and then use this getter:
The following is an example that appears to work but seems unstable to me: (note that "accordionState"references an object within a data store attached to the "page" element):
There are many other cases where I have get or setbackgroundPosition,especially in the 'over' and out' functions where I use hoverIntent.
As a great fan and user of jQuery, I am puzzled that this will not work in IE8. Note thatbackgroundColor does not work either, although I do use UI to do these sorts of things and it seems to work in IE.

There is a live search on my web page but the box of available options which falls below the 'input' field has a transparent background color. How can it be changed to non-transparent?This line below makes the background white, but all the text on the page shines through, since the default is transparent.
[CODE]
document.getElementById("linksearch").style.backgroundColor="#FFFFFF";
[CODE]
This instruction line does not help much 'cos I can't figure out the correct way to make it work:

i want to animate the backgroundcolor of the <body> when the page is loaded. It works - but sometimes when i switch from one page to another or if i just reload a page, it doesnt change.First i used this script:
<script>
$(window).load(function(){
$("body").animate({ backgroundColor: "#bdc58f" }, 1000);[code].....
But it doesn't make any difference - both are working generally, but sometimes if i load a page it doesnt change the color.

I have a simple example below showing how when I pass in the value of the value attribute of option node, and then use if operator to check whether parameter is a string or not, even though it's a string, it converts it to false boolean and triggers the else statement rather than calling a function.callback should be a string so why is it saying otherwise?

Code:
<p>
<label for="firstname">First Name: </label>
<input id="firstname" type="text" name="firstname" /><br />[code]....
Or I have created a pastebin of it here, for easy reading: http://pastie.org/1171757.So I need to be able to combine the three values into a string, create a md5 of the string, then call the value of the string into a hidden value all before posting the form.
