Question

嗨我的表格中有一个字符串：

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

与JSON / GetNames服务相关联。

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

Answer 1

有了这个：

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名称（更短）：

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

干杯

Answer 2

Ehh for循环通常有效（一旦数据被解析）。

for (var i = 0; i < data.vegetable.length; i++) {
    console.log(data.vegetable[i].name);
}
