How do I check if the string contained in a variable is a valid font on the user's system?

JS strings don't contain font information.

Can I turn the JS string into something that would contain font information?

Or do you mean for example that a variable would contain "Trebuchet MS" and you want to check if "Trebuchet MS" is available on the client system?

Yes, that's it!

Not as far as I can tell. If you want to use a certain font, use CSS and you can have fall-back:

.myClass {
font-family: Futura, Helvetica, serif
}

Put your preferred fonts first, then end with serif, san-serif, monospace, depending on the font variant you were hoping for. so that there will always be a preferred font.

Though I did find this: Fonts Collection (Dialog Helper)

But it's IE only.

Thanks! My code (btw) is

function font(whatopenf, whatmiddlef, whatclosef) {
	var whatfontf = prompt("Font:", "Enter the font's EXACT name (like 'Courier New' rather than 'cuorier-nwe')")
	if(whatfontf != null){
		var whattextf = prompt("Text to format to the font \""+whatfontf+"\":", "")
		if(whattextf != null){
			if(whatfontf != null){
				insertAtCursor(whatopenf + '"' + whatfontf + '"' + whatmiddlef + whattextf + whatclosef)
			}
		}
	}
}

So I wanted to make sure the entered font was valid. At least I'll be able to check it in IE now.


Also, is there a way to display a combo box in something that works like prompt()?
