JQuery :: Get The Height Of Each Img In The Document?

Aug 31, 2011

I'd like to get the height of every img in a document. Here's what I've managed so far:

$("img").each(function(i, e){
alert(e);
alert(e.height());
});

Unforutunately, I can't seem to get or set the height of the images using an each() loop like this. The 1st alert works fine, returns "[object HTMLImageElement]" for the img, but the 2nd alert fails and the loop ends at that point.

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:

<?
if ((strstr (getenv('HTTP_USER_AGENT'), 'MSIE')) && (strstr
(getenv('HTTP_USER_AGENT'), &#3998;')))
{
echo"blah,blah,blah
";}?>

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.
