Question

您好我有一个数组（请参阅下面的数组的第一部分），我可以使用代码获取名称（我的代码在循环中以获取数组中的所有名称）

jsonFabric.values[i].name

给了我＆＃34; 3002-023＆＃34;

如何获取标签名称？

这会给我＆＃34; Fabric＆＃34;。

我尝试了很多变种，包括

jsonFabric.values[i].labels['name']

但他们没有得到＆＃34; Fabric＆＃34;

依旧.....

Answer 1

labels代表array。您需要访问此数组的第一个对象以打印其名称：

jsonFabric.values[i].labels[0].name

Answer 2

labels是一个数组，所以你需要选择第一个元素（如果只有一个）或循环来从每个元素中获取name。

let obj = {
  "totalRows": 151,
  "values": [{
    "width": 1338,
    "height": 2397,
    "isNew": true,
    "defaultScene": null,
    "displayUrl": "https://example.com/designs-324/3002%20023_small.png?1=1&width=500&Cache=Default&height=500&p.dc=1&mode=max&format=jpg&timestamp=636244299470877669",

    },
