_target and _currentTarget

When an event is bound to an element that contains other elements it's sometimes useful to know the inner element that triggered the event.

In this example, a “click” handler is bound to the “outer” division which contains an “inner” division. Try clicking on both outer and inner and see what's returned for _target and _currentTarget.

As you can see, _target is the innermost element where the event was triggered while _currentTarget is the element where the event handler was bound.

If available, MiServer will populate the _target and _currentTarget fields on event callbacks.
