Bad place for the scope.
This is what anonymous inline functions are for. There's also ES5's
fn.bind(this); which can be implemented in ES3 as a prototype. Your
example is also a little screwed up with it's use of document.
this.a = '1';
var that = this;
$(document).bind('scroll', function() { that.myScroll(); });
or if you add a prototype to match ES5.
this.a = '1';
$(document).bind('scroll', this.myScroll.bind(this));
