Unsaved buffer warning when switching files/buffers

I am using FuzzyFinder with Vim to open files and switch be开发者_JS百科tween buffers. It works like a charm except when the current file I am working on has some changes. Vim wouldn't let me switch the buffer till I save it:

"E37: No write since last change (add ! to override)".

Is there a way of suppressing this warning unless I am quitting the editor? All I want to do it switch to a different buffer for referencing some code and switch back.

I think you can use :set hidden.

Use the :set hidden option and Vim will hide the buffer until you come back to it.

You can also use :set confirm to deal with the unsaved buffer warning more conveniently.
