javascript - 我如何访问 JSON 文档中的子元素

Question

这是我的问题，我正在尝试解析一个具有多个对象的对象，但它们不是数组中对象的形式。我的数据如下所示

{ "Jurisdiction": {
         "Mwd Water Stdby Chg": {
             "Tax Type": "Actual",
             "Tax Amount": "$10"
        },
         "Mosq/Fire Ant Assmt": {
             "Tax Type": "Actual",
             "Tax Amount": "$7"
        },
         "Vector Control Chg": {
             "Tax Type": "Actual",
             "Tax Amount": "$2"
        },
         "Total Of Special Assessments": {
             "Tax Type": "Actual",
             "Tax Amount": "$19"
        }
    }

我实际上正在尝试将其转换为 obj 数组，例如

{ "Jurisdiction":[{
         "Tax Name" : "Mwd Water Stdby Chg",
         "Tax Type": "Actual",
          "Tax Amount": "$10"
        }...]

我尝试了多种方法来访问元素下的税收类型等，但没有成功。

var obj = JSON.parse(result);
var keys = Object.keys(obj.Jurisdiction);

for (var i = 0; i < keys.length; i++) {


  console.log(keys[i]["Tax Type"])
  console.log([keys[i]]["Tax Type"])
}

全部返回未定义

您可以使用Object.entires()和map()

const obj = { "Jurisdiction": {
         "Mwd Water Stdby Chg": {
             "Tax Type": "Actual",
             "Tax Amount": "$10"
        },
         "Mosq/Fire Ant Assmt": {
             "Tax Type": "Actual",
             "Tax Amount": "$7"
        },
         "Vector Control Chg": {
             "Tax Type": "Actual",
             "Tax Amount": "$2"
        },
         "Total Of Special Assessments": {
             "Tax Type": "Actual",
             "Tax Amount": "$19"
        }
    }
}

let res = Object.entries(obj.Jurisdiction).map(x => ({'Tax Name':x[0],...x[1]}));
obj.Jurisdiction = res;

console.log(obj)
