从json获取数组使用javascript

Question

服务器返回我这样的对象，但我只需要数组ITEMS。 我怎样才能得到它？ 我试图array['items']但结果是undefiend

{ 
    "items": [ 
    { 
     .. 
    }, 
    { 
     .. 
    }, 
    { 
     .. 
    } 
    ],.. 
    ,.. 
} 

Answer 1

// JSON string returned from the server 
var text = '{"items":[{"name":"itemX" ,"price":15},{"name":"itemY","price":25},{"name":"itemZ","price":20}]}'; 

// Convert the string returned from the server into a JavaScript object. 
var object = JSON.parse(text); 

// Accessing a specific property value of an item 
console.log(object.items[0].name); //itemX 

// Extract 'items' in to a separate array 
var itemsArray = object.items; 
console.log(itemsArray); //[itemObject, itemObject, itemObject] 

Answer 2

如果您收到这是一个字符串：

var json = JSON.parse(my_json_string) 

然后，

var keys = Object.keys(json); 
var values = []; 
for(var i = 0; i < keys.length; i++){ 
    values.push(json[keys[i]]); 
}
