Hiding links via AJAX on pages disallowed for indexation for SEO. Good or Bad & Why?

I have web pages that I've forbidden in robots.txt and also if I do not desire those web pages to leakage link juice to exterior and also inner links that show up on those web pages.

Questions:

• If I "hide" these links using AJAX what SEO relevant benefits and drawbacks would certainly this method offer me?
• Why should/shouldn' t I make use of that method?
• Just how specifically to hide the links using AJAX for the very best result?
