Techinque #1
if (Modernizr.geolocation) {
// let's find out where you are!
http://modernizr.com/ } else {
// no native geolocation support available :(
// maybe try Gears or another third-party solution
}
Techinque #2
if (Modernizr.canvas) {
// let's draw some shapes!
} else {
// no native canvas support available :(
}
Techinque #3
if (Modernizr.video) {
// let's play some video! but what kind?
if (Modernizr.video.webm) {
// try WebM
} else if (Modernizr.video.ogg) {
// try Ogg Theora + Vorbis in an Ogg container
} else if (Modernizr.video.h264){
// try H.264 video + AAC audio in an MP4 container
}
}
Techinque #4
if (!Modernizr.inputtypes.color) {
// no native support for <input type="date"> :(
// maybe build one yourself with Dojo or jQueryUI
}
