Web Notifications var notification

new Notification(  

'Your life is in danger' ,  

{ body :

'You forgot to take your pills' , icon :

'skull-and-crossbones.png'

); The Notification constructor takes a title, and then an object containing options. Basic options are ‘body’ for the message and ‘icon’ for an icon to show with the notification.

Web Notifications var notification

new Notification(

'Your life is in danger' , { body :

'You forgot to take your pills' , icon :

'skull-and-crossbones.png' , tag :

'pills-warning' , lang :

'en-US' , dir :

'ltr'

); The ‘tag’ option acts like an ID for the notification. If there are multiple instances of your code running (e.g. two browser windows) the tag prevents the notification being duplicated. It can also be used to address the notification to cancel it.

Web MIDI function failure() {

// MIDI access denied :( } function succes s(midi) {

var inputs

midi.inputs.values();

for ( var input

inputs.next(); input &&

! input.done; input

inputs.next()) {

input.value.onmidimessage

= messageReceived ; } } If we have access to MIDI, our success callback gets a MIDIAccess object. From this we can get all the different MIDI inputs we have access to, using an interator. This code loops through the inputs adding an event listener for the onmidimessage event.
