如何在多个级别上迭代JSON? [英] How to iterate JSON with multiple levels?

问题描述

欢迎，我遇到了JSON文件问题.我想遍历所有状态并将所有状态放入数组，但是我陷入了困境.我加载并解析它.然后，我尝试使用forEach，但没有成功.感谢您的帮助！

Welcome, I got a problem with JSON file. I would like to iterate through it and get every status into array, but I got stuck. I load this file and parse it. Then I tried to use forEach but it did not worked. Thanks for help!

[{
  "offers": [{
    "advertiser_api_id": 12,
    "status": 1
  }, {
    "advertiser_api_id": 13,
    "status": 0
  }]
}]

推荐答案

这将遍历对象并将数据打印到控制台-您可能未到达要遍历的正确数组.

This loops through the object and prints the data to console - you likely did not reach the correct array to loop through.

var data = [{
  "offers": [{
    "advertiser_api_id": 12,
    "status": 1
      }, {
    "advertiser_api_id": 13,
    "status": 0
  }]
}];

data[0].offers.forEach(function(element) {
  console.log(element.status);
});
