PRIME NG 中 TreeTable 的 JSON

  • 772

生成此类 JSON 的最佳方法是什么？

let main = {

  "data": [{
      "data": {
        "name": "zzzzzz"
      },
      "children": [{
          "data": {
            "name": "Test1"
          }
        },
        {
          "data": {
            "name": "Test2"
          }
        },
        {
          "data": {
            "name": "Test3"
          }
        }
      ]
    },
    {
      "data": {
        "name": "zzzzzzz"
      },
      "children": [{
          "data": {
            "name": "Test1"
          }
        },
        {
          "data": {
            "name": "Test2"
          }
        },
        {
          "data": {
            "name": "Test3"
          }
        }
      ]
    }
  ]
}

我制作了自己的版本，但远非最佳。谢谢！

let arrr = [];
let arrr2 = [];
let objData3 = {};
let objData4 = {};

for (let itemz in arr) {
  let a = arr[itemz];

  let objNameInData = {};
  let objNameInData2 = {};
  let startObj = {};
  startObj.name = a.ServiceName;

  objNameInData.name = startObj;
  objNameInData2.name = "zzzzz"

  let objDataInChildren = {};
  let objDataInData = {};


  objDataInChildren.data = objNameInData.name;
  arrr.push(objDataInChildren);
  objData3.data = objNameInData2;
  objData3.children = arrr;
  arrr2.push(objData3)
  objData4.data = arrr2;
}

console.log(JSON.stringify(objData4, null, 4))

    const createJSON = count => Object.create(Object.prototype, {
  data: {
    value: Array.from(Array(count).keys(),e=>Object.create(Object.prototype,{
      data: {
        value: Object.create(Object.prototype,{
          name: {
            value: "zzzzzz",

    选项 2

    const createJSON = count => Object.create(Object.prototype, {
  data: {
    value: Array.from(Array(count).keys(),e=>JSON.parse('{"data":{"name":"zzzzzz"},"children":[{"data":{"name":"Test1"}},{"data":{"name":"Test2"}},{"data":{"name":"Test3"}}]}')),
    writable: true,
    enumerable: true,
    configurable: true
  }
});
let main = createJSON(2);
console.log(main)
