JavaScript has a number of nice features that do make sense, and if you understand how prototype chains work and such the complexity is worthwhile. "This" hasn't been one of those features for me. I'm sure "this" makes sense in some context, but it forces me to think about the implementation of the language way too much without any benefit that I consider it a misfeature. So I don't use it. Instead, I capture it with another variable in a prototype declaration: var that = this; and refer to "that" everywhere in the prototype. Tends to be a lot simpler, and usually for event handlers I'll create a closure to avoid the issue entirely.
