Is there a way to call a function (or a property) on an object via reflection, in JavaScript? Lets say that during run-time, my code has already determined that objectFoo indeed has a property called 'bar'. Now that my code knows that, the next thing I want to do is invoke that.

I am trying to find a simple way to have a div with just text in it automatically scroll the text vertically. I don't want to use a framework (though I do use Prototype, so if it is easier using Prototype then that is fine, but no Scriptalicious).

Here's my code: var map = null; var marker = null; var layer = null;...
