1.2.0

Changes

• Reorganized the code into an event dispatcher (BellhopEventDispatcher) and the main class (Bellhop)
• Added some basic functionality tests for Travis
• Added support for NPM using require
• In the parent Bellhop instance, no longer saving a reference to contentWindow, instead using a reference to the iframe, in case the iframe changes src, doesn't break in iOS9
• Fixed a bug when adding multiple events to a single handler, e.g. bellhop.on('start end progress', function(){})

1.1.8

Changed the target of the child Bellhop instance to be window.parent instead of window.top in situations where the child depth is greater than 1 iframe deep.

1.1.7

Further protection for just-in-case use after destroy()

1.1.6

The same bellhop instance may now be re-used after destroy()

1.1.5

• Child Bellhop instance can now call connect() after the DOM has loaded

1.1.4

Add ability to remove all listeners


1.1.3

Added priority parameter to .on() for setting order of callbacks.

1.1.2

• When using the fetch() and respond() pair, we add the ability to have the data returned by respond() be generated by a function. This function is called when respond() is invoked, and its return value is returned as data.

1.1.1

• Bellhop now supports a format for transporting typed instances of custom JavaScript classes (See the examples/object.html file as an example). There are a few prerequisites for getting this to work:
  1. The class instance must contain methods toJSON():object and fromJSON(object) in order to properly serialize to and from a generic JSON object.
  2. The toJSON function must add a key to the output JSON object called __classname which is a string reference to constructing class.
  3. Both the parent the child window must have a reference to the same class being used.
• Here's an example of a typed serializing class that would work with Bellhop:

(function(){

    var Bicycle = function(color, name)
    {
        this.color = color; 
        this.name = name;       
    };

    Bicycle.prototype.toJSON = function()
    {
        return {
            color : this.color,
            name : this.name,
            __classname : 'vehicles.Bicycle' 
        };
    };

    Bicycle.prototype.fromJSON = function(data)
    {
        this.color = data.color;
        this.name = data.name;
    };

    window.vehicles = window.vehicles || {};
    window.vehicles.Bicycle = Bicycle;

}());

1.1.0

• Removed the need for a handshake identifier
• Works with multiple Bellhop instances on the same parent page
• Fixed issues with catching JSON errors
• Removed Function.prototype.bind polyfill from the source (now a Bower dependency)
• Re-implemented failed event for when connection fails
