I have a quick question regarding the proper way to access Javascript class member variables from inside of an event handler that class uses. For example: function Map() { this.x = 0; this.y = 0; $("body").mousemove( function(event) { this.x = event.pageX; // Is not able to access Map's member variable "x" ...

Most of the time I see code registering an event listener for a link or a div or button, and handle everything from there. But the event capturing and bubbling is good to handle events at the offspring and then at the ancestor level. But what is a good example we will want to listen at 2 different places? ...
