Easily communicate among browser tabs(supports cross-origin).

Features

1. Safely enables cross-origin communication among different browser tabs. Uses PostMessage API for communication.
2. Easy to hook custom callback at various levels. Eg: executing a custom method in Child's tab on receiving a message from Parent tab.
3. Option to provide data-tab-opener="name" attribute on the target link/btn(which opens up a new tab), so that it remains disable until Child tab initiates a handshake and is received by the Parent tab
4. Fully fledged API to get information regarding the tabs(Parent and Child tabs) and other communication related methods.
5. Exports in a UMD format i.e. library works everywhere.

Browser Support

Tested in Chrome, Firefox and IE(versions >= 9).

Example

Create an instance / reference before using.

Opener(Parent) tab

var config = {
  onHandshakeCallback: function () { ... },
  onPollingCallback: function () { ... }
}
var parent = new AcrossTabs.Parent(config);

New(Child tab)

var config = {
  onReady: onReady,
  onInitialize: onInitialize,
  handshakeExpiryLimit: 4000, // msec
  onParentDisconnect: onParentDisconnect,
  onParentCommunication: onParentCommunication
};
var child =  new AcrossTabs.Child();

That's it! The communication setup would be set up once the new tab is opened up.
