I have some json like
{"111-222":"AAA","333-444":"BBB"}
when I want to get the value of "111-222", javascript will show "Uncaught ReferenceError: 222 is not defined?
How can I resolve this problem?

"when I want to get the value of..." So how are you trying to get the value? – Marc Mar 08 '18 at 03:08

You can only use dot notation where the key meets the parameters for an identifier. Otherwise, use square brackets. I.e. use `obj['111-222']` not `obj.111-222`. – RobG Mar 08 '18 at 03:09
