jquery - 循环遍历 JSON 响应对象

Question

我从 API 收到如下响应。例如，如何使用 jQuery 循环访问结果来访问“appName”的值？

var apps = 
{ 
  358899126: 
   { appId: 358899126,
     appName: 'Tagged -Chill, Chat & Go Live!',
     primaryCategoryName: 'Social Networking' },
  359917414: 
   { appId: 359917414,
     appName: 'Solitaire',
     primaryCategoryName: 'Games' } 
}

Answer 1

您可以使用Object.keys获取每个对象的键，然后使用方括号语法获取实际对象，如下所示:

var apps = 
{ 
  358899126: 
   { appId: 358899126,
     appName: 'Tagged -Chill, Chat & Go Live!',
     primaryCategoryName: 'Social Networking' },
  359917414: 
   { appId: 359917414,
     appName: 'Solitaire',
     primaryCategoryName: 'Games' } 
}

Object.keys(apps).forEach((key) => {
  let obj = apps[key];
  console.log(obj.appName);
});
