javascript - 如何从 getRequest 获取 JSON

Question

嗨，我有一个以下形式的字符串:

{"Fruit":"Meat",
     "Vegetable":[
       {"Name":"Author1","Date":"12"},
       {"Name":"Author2","Date":"2"},
       {"Name":"Author3","Date":"14"}
       .
       .
       .
       {"Name": "AuthorN", "Date":"18"}
    ]
} 

与 JSON/GetNames 服务关联。

什么 JavaScript 函数可以解析并返回“Vegetable”下的每个“Name”？

Answer 1

这样:

var jsonStr = '{"Fruit":"Meat","Vegetable":[{"Name":"Author1","Date":"12"},{"Name":"Author2","Date":"2"},{"Name":"Author3","Date":"14"}...{"Name": "AuthorN", "Date":"18"}]}';    
var object = JSON.parse(jsonStr),
    names = [];

for (var i = 0; i < object.Vegetable.length; i++) {
    var item = object.Vegetable[i],
        name = item.Name;
    names.push(name);
}
//Finally print the result:
console.log(names);

或者如果您只想打印姓名(较短):

var object = JSON.parse(jsonStr);
for (var i = 0; i < object.Vegetable.length; i++)
    console.log(object.Vegetable[i].Name);

干杯
