Use string.replace.

string.replace(/(['"])/g, "\\$1")

Example:

> var s = 'Annie said, "It\'s really funny."'
undefined
> console.log(s.replace(/(['"])/g, "\\$1"))
Annie said, \"It\'s really funny.\"

you guys are so awesome. @hwnd and avinash-raj I want to ask a question, which is better and more efficient in order to get this done, use 2 replace for ' and " or just use this regex?
