Hi, Your syntax is fine. If you're callilng explainYourself like this:
Advertising
this.explainYourself(); ...it should work. How are you calling it? Because context (the meaning of the "this" keyword) is slightly different in JavaScript than in other languages using that keyword, and it's easily lost. For instance: var f; f = this.explainYourself; // Getting a reference to the function, not calling it f(); // Now I'm calling it That would fail because "this" would not be a reference to an instance of myClass when the function was called. Here are some resources for reading up on context: [1] http://blog.niftysnippets.org/2008/03/mythical-methods.html [2] http://blog.niftysnippets.org/2008/04/you-must-remember-this.html [3] http://www.alistapart.com/articles/getoutbindingsituations [4] http://proto-scripty.wikidot.com/prototype:tip-using-an-instance-method-as-a-callback-or-event-handler HTH, -- T.J.
