Event Emitter

This is the heart of Jodit. All processes inside Jodit mostly flow through events.

const jodit = Jodit.make('#editor');
jodit.e.on('someEvent', param => alert(`Some event fired for ${param}!!!`));
jodit.async.setTimeout(() => {
  jodit.e.fire('someEvent', 'you');
}, 1000);

In addition to custom events, the emitter can work with DOM elements and browser events:

jodit.e.on(document.body, 'click', () => alert(`Doc click!!!`));

If you don't want to listen to the event anymore, you can unsubscribe from it:

jodit.e
  .one('someEvent', param => alert(`Some event fired for ${param}!!!`))
  .one('someEvent', param => alert(`Some event fired for ${param}!!!`))
  .one('someEvent', param => alert(`Some event fired for ${param}!!!`));

jodit.e.off('someEvent'); // will unsubscribe from all handlers

const handler1 = param => alert(`Some event fired for ${param}!!!`);
const handler2 = param => alert(`Some event fired for ${param}!!!`);
const handler3 = param => alert(`Some event fired for ${param}!!!`);

jodit.e
  .one('someEvent', handler1)
  .one('someEvent', handler2)
  .one('someEvent', handler3);

jodit.e.off('someEvent', handler1); // only handler1 will unsubscribe

Example

const obj = {
  a: 1,
  b: {
    c: 5
  }
}

const obsObj = Jodit.modules.observable(obj);
console.log(obj === obsObj); // true
obsObj.on('change', () => {
  console.log('Object changed');
});
obsObj.on('change.a', () => {
  console.log('Key a changed');
});
obsObj.on('change.b.c', () => {
  console.log('Key b.c changed');
});

obj.a = 6;
// Object changed
// Key a changed

obj.b = {c: 6}
// Object changed

obj.b.c = 8
// Object changed
// Key b.c changed
