How JSON strings are represented in JavaScript and Java code

When I recently used JS to write a JSON-style string, when I put the JSON form string into the function json.parse (), always error uncaught syntaxerror:unexpected token '

javascript: Among

The string is:

var StrJso2 = "{' UserID ': ' One ', ' Name ': ' WP ', ' email ': ' [email protected] '}";

It looks right, but it's actually a background error.

The correct format is:

var strjso2= ' {"UserID": "One", "Name": "WP", "email": "[email protected]"} ';

Pure JS string preferably using double quotation marks

Java code

So write String strjson= ' {"UserID": One, "Name": {"FirstName": "tht", "LastName": "Tang"}, "email": "[email protected]"} '; Must be wrong, because the single quote is the char type

Correct format:

String strjson= "{' UserID ': One, ' Name ': {' FirstName ': ' tht ', ' LastName ': ' Tang '}, ' email ': ' [email protected] '}";

Or

String strjson= "{\" userid\ ": \" 11\ ", \" name\ ": {\" firstname\ ": \" tht\ ", \" lastname\ ": \" tang\ "}, \" email\ ": \" [Email Protected]\ "}";
