If you are okay with them being able to see their text as they type it in, and, when they leave the field, you change it to your obfuscated text, then all you have to do is handle the focus and blur events on the input and do a string replace. You would store the user's value in a hidden form field or other storage mechanism (like a data attribute).

Are you using any JavaScript libraries (like jQuery)? It would make this kind of thing a lot easier.
