javascript - 尝试循环遍历 Json 对象，该对象内部有更多对象和对象数组

Question

我一直在用头撞墙试图循环遍历这个 json 文件。

当我控制台记录它时，它说响应是一个对象，数据是一个对象，saleItemCategories 是一个数组，其中有四个对象，第一个是车辆，它是项目对象的数组。

基本上我试图从这些项目对象中获取各种值。此时，我只是寻求深入了解此级别的帮助。

"Response":{

我尝试将每个 Response 作为对象循环，然后将每个数据作为对象循环，然后我尝试循环 saleItemCategories 数组，但这通常是它中断的地方

Answer 1

var json = "your data";

var itemCategories = json.Response.data.saleItemCategories;

for (int i = 0; i < itemCategories.length; i++) {
  var categoryItems = itemCategories[i].saleItems;
  console.log(categoryItems.categoryTitle);

  for (int j = 0; j < categoryItems.length; j++) {
    var categoryItem = categoryItems[j];
    var categoryItemStats = categoryItem.stats;

    console.log(categoryItem.itemHash);

    for (var k = 0; k < categoryItemStats; k++) {
      var categoryItemStat = categoryItemStats[k];

      console.log(categoryItemStat);
    }
  }
}
