Determining Supported CSS Attributes?

Nov 23, 2009

Is there anyway using Javascript, one can determine whether or not the browser viewing the page supports a particular CSS property or value? For example, I know IE6 doesn't support the value of "fixed" for the "position" property, so is there anyway I can determine this with Javascript, without resorting to browser sniffing?

SetTimeout() Function Not Supported In An IE Version

Jul 30, 2009

does anyone know if the setTimeout() function in js has been just recently supported? i created an online demonstration of a product that uses this function to delay the playing of .wav files after various second intervals. i know that Opera doesn't support this function because when I click my button, all of the .wav files that i have in the function that runs behind the button play at once. i have probably 10 wav files that are played throughout the function, at various conditional statements. does anyone know if earlier (like REALLY old) versions of IE do not support this function? or maybe ie8 doesn't support it? i developed this and tested it in all major browsers except IE8 and any version earlier than IE6.

Extract A List Of Supported Events In Firefox‏ Programmatically?

Jun 30, 2011

I need to obtain a list of supported events on an encountered browser version programmatically, ie, via script. Since Explorer exposes its events on document object I can do something as simple as this:

;for(x in document)if(/^on/.test(x))alert(x);

(!warning: long list ahead..., you can use the console.log(x) instead) ..and simply store them on some appropriate object for latter use in my program flow.

Is there a sort of hack or "a hidden corner" or whatever, that would enable us to build a list of events available on Firefox in a similar fashion?

So I have this script that will let me detect whether @font-face is supported by the browser. Once this script runs then isFontFaceSupported() // will return a boolean indicating support.

So I just want to load a single .css stylesheet if isFontFaceSupported returns a 1, and if it returns a 0, then it does nothing, finished.

Here is the script.

The following is a font-face glyph definition for the . character:

Determining The Existance Of An Element

Aug 17, 2006

I was wondering if there was any method for determining the existance (or no existance) of a given DOM element using its Id.

My problem is the following :

I have some ajax stuff that does some crazy things to my original document well... errr... such as simply adding some new layers with a unique Id.

What I wanted to do, from another JS function that is triggered later on, was to check if theses layers were existing or not before populating them.

For example something like :

if (document.getElementById("blah").exists){

//populate the thingie !

Determining The Engine Version In FF

Feb 9, 2010

While attempting to create a greasemonkey script in FF2 (don't ask), I discovered that the "let" statement was causing my code to fail. After confirming that this statement has been available since FF2 (js engine 1.7) [URL] became curious as one determines their javascript engine in FF. IE has a way to inspect the jscript engine, ala [URL] but I couldn't find anything similar for FF. Feel free to list links for testing engines in other browsers,

Determining If User Is Using Win98 & MSIE

Jul 23, 2005

If a user is using a combination of Win98 & any version of MSIE, I
want to display a message. The best that I can do is the following:

(getenv('HTTP_USER_AGENT'), &#3998;')))

Is there a better (more foolproof) way?

Determining Caps Lock State

Oct 27, 2005

I was wondering if the was any way to determine the state of the caps
lock key, on or off. Of course I can capture the key events and see whether the caps lock is pressed, but that does not help.

I have seen some example that looks at the characters entered in an
input field to determine if the caps lock is on, but I was wondering if
something is possible that is a bit more immediate to report the caps
lock state.
