When I console print I get value of var a as Object{}, which is empty JSON Object Using jQuery how do I check for the empty value? Thank you.
回答1:
Use the jQuery function:
jQuery.isEmptyObject( object )

EDIT: As I always say... and insist on it. Rule number one of the programmer:
"Man pages are your best friend" or the one I was slapped with in school "F1 is there for a reason"
