<script src="lib/font-detective.js"></script>
<script>
	FontDetective.each(function(font){
		$("<option>")
			.val(font)
			.text(font.name)
			.appendTo("select");
		
		font.name; // e.g. 'Arial'
		font.toString(); // e.g. '"Arial"'
	});
	
	FontDetective.all(function(fonts){
		console.log(fonts);
	});
</script>

Documentation

FontDetective.each(callback)

• Calls back with a Font every time a font is detected and tested
• Fonts are tested in chunks to avoid totally freezing the page

FontDetective.all(callback)

• Calls back with an Array of Fonts when all fonts are detected and tested

FontDetective.preload()

• Starts detecting fonts immediately
• Not needed if you're going to call all or each right away

FontDetective.Font

• Fonts are returned as instances of this class
• The font.name property can be used to display the name of the font
• The font can be used anywhere you'd use a font-family (e.g. div.style.fontFamily = font)

Node.js
