试图循环遍历内部有更多对象和对象数组的 Json 对象

Question

我一直在试图循环这个 json 文件。

当我在控制台记录这个时，它说响应是一个对象，数据是一个对象，saleItemCategories 是一个数组，它有四个对象，第一个是车辆，它是一个项目对象数组。

基本上我试图从这些项目对象中获取各种值。在这一点上，我只是在寻求深入到这个级别的帮助。

"Response":{

                 "failureIndexes":[

                 ]
              },

我尝试将每个响应作为对象循环，然后将每个数据作为对象循环，然后我尝试循环通过 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);
    }
  }
}
