copied!<p>To make this work you need to capture the _super method while in the subclassed method, like this:</p> <pre><code>dance: function(){ // capture the super method for later usage var superMethod = this._super; window.setTimeout(function(){ return superMethod(); },50); }; </code></pre> <p>The reason this works, and your code does not, is that the <code>extend()</code> method in inherit.js captures the superclass' method as <code>this._super</code> right before your overridden method is run. It then runs your code, and after your code has run it restores _super to whatever it was set to before it ran. The action takes place in the following bit of code from inherit.js</p> <pre><code> var tmp = this._super; // Add a new ._super() method that is the same method // but on the super-class this._super = _super[name]; // The method only need to be bound temporarily, so we // remove it when we're done executing var ret = fn.apply(this, arguments); this._super = tmp; return ret; </code></pre> <p>So to be more specific; when the original code was run, the function that was used as a parameter to setTimeout was bound to the original object. The reason it did not work was that, even though <code>this</code> referenced the right object, <code>this._super</code> referenced something else, since <code>this._super</code> was reset to point to whatever it pointed to before the method was run. Probably it was not set, so the value of <code>this._super</code> was most likely just <code>undefined</code>.</p>
