Nov 23, 2009Is there anyway using Javascript, one can determine whether or not the browser viewing the page supports a particular CSS property or value?

Determining The Existance Of An Element
Aug 17, 2006I 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, 2010While 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 Caps Lock State
Oct 27, 2005I 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.

View 1 Replies View RelatedDetermining When IFRAME Load Is Complete
May 5, 2006I have found a couple different code snippits that allow you to determine when a page has finished loading in an IFRAME. However, what I need is a way to determine this when it is a form that is POSTing to that IFRAME (which is on a remote web site).
Basically on my page there is a button that submits a form to another website and the target = the IFRAME. However, I don't want to actually display the content from the other site (and so the IFRAME is invisible). I just need to know when the submission is complete. As a user you can tell by watching the status bar in IE to see that the submission is still processing, but I'm looking for a more elegant way to do this (as I want to tie it into a mechnism that will visually show the user the status of the submission in real time.)
