May 29, 2009 Javascript: passing object self reference to anonymous functions nested within multiple objects
I know the title of this post is a little complicated but I feel it best describes the problem at hand. In Javascript, objects, arrays and variables are all technically the same thing which allows you to do some interesting stuff - such as nesting functions inside arrays inside variables inside objects inside variables.

This javascript function will allow you to easily inject text into a textarea wherever the caret/cursor is currently at.
