JSON object and string cross-transfer

$sui = [    ' xixixi ' = ' Suisuisui ',    ' hahaha ' = ' longlonglong ',]; $data = Json_encode ($sui); Print_r ($data);

JSON string ===> JSON object

# Way One: through eval
var str = ' {' Xixixi ': ' Suisuisui ', ' hahaha ': ' Longlonglong '} ';

var obj = eval (' (' + str + ') ');
Console.log (obj);

# Way two: Json.parse (str)

var str = ' {' Xixixi ': ' Suisuisui ', ' hahaha ': ' Longlonglong '} ';

var obj = json.parse (str); Convert from JSON string to JSON object
Console.log (obj);
typeof (obj);

JSON Object ===> JSON string

var last=obj.tojsonstring (); Convert a JSON object to a JSON character

Or

var last=json.stringify (obj); Convert a JSON object to a JSON character
