I'm not sure I see the benefit of AJAXing it in as I would hope that the code example would be sourced from the same page as the working example (rather than maintaining a separate file). What would be better would be something like:

```js
$( "#sourcecode1" ).text( $( "#example1" ).html() );
```

That way you wouldn't have to worry about keeping the separate source code file in sync with the working example.
