function MyApplication() {
this.counter = 0;
this.map = new GMap2(document.getElementById("map_canvas"));
this.map.setCenter(new GLatLng(37.4419, -122.1419), 13);
GEvent.bind(this.map, "click", this, this.onMapClick);
}
MyApplication.prototype.onMapClick = function() {
this.counter++;
alert("You have clicked the map " + this.counter +
(this.counter == 1 ?" time":" times"));
}
function initialize() {
if (GBrowserIsCompatible()) {
var application = new MyApplication();
}
}
This is a example code taken from the google maps api documentation.
In the GEvent() function we refer to the method we want to bind the
event to as:
this.onMapClick.
It is my understanding that 'this' refers to 'MyApplication()'
so this.onMapClick = MyApplication.onMapClick
So why do we have
MyApplication.prototype.onMapClick = function()
Where does the 'prototype' come from?
