jFont Checker

This simple tool checks for the existence of a specified font. It ultilizes the font fallback mechanism in CSS for font checking.


Simply call checkfont, and it will return the font status in boolean:

var isTimesExist = checkfont("Times"),           //true (if exists)
    someWeirdFont = checkfont("CookieMonster");  //false

For whatever reason you need to test on a different DOM, another window for example (limited by SOP), you can pass that in too.

var win ="/another_page");
checkfont("Century Gothic", win.document);
