document.write

问题 In tutorials I've learnt to use document.write . Now I understand that by many this is frowned upon. I've tried print() , but then it literally sends it to the printer.

问题 This is all I've got going, but my debugger says 'document.write can be a form of eval,' and my jsonString variable prints as undefined.
