Sometimes the JSON returned by the background is not actually a real JSON. For JavaScript, it is equivalent to a string and needs to be converted to a real JSON.

VaRT="{'Firstname': 'cya', 'lastname': 'chardson ', 'address': {'streetaddress': '1 Microsoft way', 'city ': 'redmond ', 'state': 'wa', 'postalcode': 98052}, 'phonenumbers ': ['2017-777-7777', '2017-777-7777 ']}";VaRJsonobj=Eval('+ T + ')');

For example, you want to obtain the firstname after the conversion. You can directly obtain internal parameters using jsonobj. firstname.

Eval is a built-in JavaScript method.
