can-event-queue/value/value

  • Edit on GitHub

Mixin methods and symbols to make this object or prototype object behave like a single-value observable.

mixinValueBindings( obj )

Adds symbols and methods that make obj or instances having obj on their prototype behave like single-value observables.

When mixinValueBindings is called on an obj like:

var mixinValueBindings = require("can-event-queue/value/value");

var observable = mixinValueBindings({});

observable.on(function(newVal, oldVal){
  console.log(newVal);
});

observable[canSymbol.for("can.dispatch")](2,1);
// Logs: 2

mixinValueBindings adds the following properties and symbols to the object:

  • on
  • off
  • @can.dispatch
  • @can.getWhatIChange
  • handlers

When the object is bound to for the first time with .on or @can.onValue, it will look for an onBound function on the object and call it.

When the object is has no more handlers, it will look for an onUnbound function on the object and call it.
