服务器返回我这样的对象,但我只需要数组ITEMS。
我怎么才能得到它?
我尝试了array['items']
,但结果是undefiend
{
"items": [
{
..
},
{
..
},
{
..
}
],..
,..
}
最佳答案
// 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]
