JSON(json的分類 各種型的轉換 等)

1、json的分類

1一個JSON對象——JSONObject

{"name":"胡小威" , "age":20 , "male":true}

var json2= { "firstName":"John" , "lastName":"Doe" };

2.一個JSON數組——JSONArray

[{"name":"胡小威" , "age":20 , "male":true},{"name":"趙小亮" , "age":22 , "male":false}]

var json1=[

{ "firstName":"John" , "lastName":"Doe" },

{ "firstName":"Anna" , "lastName":"Smith" },

{ "firstName":"Peter" , "lastName": "Jones" }

];

三、對象數組

var json = '{ "employees" : [' +

'{ "firstName":"John" , "lastName":"Doe" },' +

'{ "firstName":"Anna" , "lastName":"Smith" },' +

'{ "firstName":"Peter" , "lastName":"Jones" } ]}';
