FontFaceSet.check() support is good enough to be used but will need a fallback e.g.Detecting all available fonts is common browser fingerprinting technique so it is unlikely any JS API will ever be added which will directly return a list.Width and height for the same string of characters of same font-size.
#Arial zawgyi font for windows 10 code#
This code works on the simple principle that each character appearsĭifferently in different fonts. Var matched = (s.offsetWidth != defaultWidth] || s.offsetHeight != defaultHeight]) S.style.fontFamily = font + ',' + baseFonts // name of the font along with the base font for fallback. get the default width for the three base fontsĭefaultWidth] = s.offsetWidth //width for the default fontĭefaultHeight] = s.offsetHeight //height for the defualt font create a SPAN in the document to get the width of the text we use to test Var h = document.getElementsByTagName("body") we test using 72px font size, we may use any size. And we use a LLi so that the same matching fonts can get separated we use m or w because these two characters take up the maximum width. and if it doesn't match all 3 then that font is not available. a font will be compared against all the three default fonts. * Replaced sans with serif in the list of baseFonts * then that font is 100% not available in the system * Comparing font against all the 3 generic font families ie, * to parent element if the font is missing. * as in FF3.0 font of child element didn't fallback * Changed comparision font to default from sans-default-default, * particular font in a browser using JavaScript and CSS. * JavaScript code to detect available availability of a Yes there is! I'm so glad you asked this question because I now want to use this too.
