    copied!<p>So, I'm trying to extend a google maps class, specifically google.maps.OverlayView (in v3). Doing it the vanilla js way totally works.</p> <pre><code>POIOverlay = function(marker, poi, type) { this._marker = marker; this._poi = poi; this._type = type; this._div = null; this.latlng_ = marker.getPosition(); this._map = marker.getMap(); this._offsetVertical = -195; this._offsetHorizontal = 0; this._height = 165; this._width = 266; } POIOverlay.prototype = new google.maps.OverlayView(); POIOverlay.prototype.create = function() { console.log(this) } POIOverlay.prototype.draw = function() { //stuff } </code></pre> <p>However, doing it the prototype way, fails to add any of the parent class methods:</p> <pre><code>POIOverlay = Class.create(new google.maps.OverlayView(), { initialize : function(marker, poi, type) { this._marker = marker; this._poi = poi; this._type = type; this._div = null; this.latlng_ = marker.getPosition(); this._map = marker.getMap(); this._offsetVertical = -195; this._offsetHorizontal = 0; this._height = 165; this._width = 266; }, create : function() { if(this._div) return; console.log(this); }, draw : function() { //stuff } }); </code></pre> <p>Here is the code to instantiate/use the class:</p> <pre><code> try { poio = new POIOverlay(marker,poi,type); } catch(e) { console.log(e); } google.maps.event.addListener(marker, 'click', poio.draw.bind(poio) ); </code></pre> <p>In the first example, the console logs an object with the parent and child methods/attributes. In the second example, the console logs an object with no parent attributes/methods.</p> <p>Obviously, this is not too big of a deal, but I was wondering in anyone else has run into this issue and if it is easily corrected. I am using prototype 1.7.</p>
