Javascript-遍历Json对象并获取每个项目的层次结构键，包括嵌套的对象和数组 [英] Javascript - Traverse through the Json Object and get each item hierarchical key including nested objects and arrays

问题描述

我想获取包括任何JSON对象在内的值和键，作为甚至可以用于复杂对象的通用方法

json

{
  "timezone": 5.5,
  "schedule": {
    "type": "daily",
    "options": {
      "hour": 10,
      "minute": 29
    }
  }

想要像这样的分层模式中的值和键

want the values and keys in hierarchical schema just like these

timezone - 5.5
schedule.type - daily
schedule.type.options.hour - 10
schedule.type.options.minute - 29

此外，我使用此函数可以获取JSON对象的所有对象键和值，即使在嵌套数组和对象中也是如此

Also, I used this function can get the JSON objects all objects keys and values even in the nested arrays and objects in that

function iterate(obj) {
  for (var property in obj) {
      if (obj.hasOwnProperty(property)) {
          if (typeof obj[property] == "object") {
              iterate(obj[property]);
          } else {
            console.log(property , obj[property])
          }
      }
  }
  return obj;
}

PS-我也是还要将此用于数组

PS - Also I want to use this for arrays also

"dirs": [ { "watchDir": "Desktop/logs", "compressAfterDays": 50 }, { "watchDir": "Desktop/alerts", "timeMatchRegex": "(.*)(\\d{4})-(\\d{2})-(\\d{2})-(\\d{2})_(\\d{2})(.*)", }]

我想要的输出就是这样

dirs[0].watchdir="Desktop/alerts"
dirs[1].watchDir="Desktop/logs"

推荐答案

const obj = { "timezone": 5.5, "dirs": [ { "watchDir": "Desktop/logs", "compressAfterDays": 50 }, { "watchDir": "Desktop/alerts", "timeMatchRegex": "(.*)(\\d{4})-(\\d{2})-(\\d{2})-(\\d{2})_(\\d{2})(.*)", }] ,"schedule": { "type": "daily", "options": { "hour": 10, "minute": 29 }, 'available': true } };

function iterate(obj, str) {
  let prev = '';
  for (var property in obj) {
    if (obj.hasOwnProperty(property)) {
      if (typeof obj[property] == "object") {
        const s = isArray(obj) ? prev + str + '[' + property + ']' + '.' : prev + property + (isArray(obj[property]) ? '' : '.');
        iterate(obj[property], s);
      } else {
        prev = (str != undefined ? str : '');
        console.log(prev + property, '- ' + obj[property]);
      }
    }
  }
  return obj;
}

function isArray(o) {
  return o instanceof Array;
}

iterate(obj);
