Javascript通过数组路径更新嵌套对象中的值

Question

给定嵌套对象:

{
    name: 'UK',
    toggled: false,
    active: false,
    children: [{
            name: 'Region 1',
            active: false,
            toggled: false,
            children: [{
                    name: 'Heathrow T1',
                    toggled: false,
                    active: false,
                    children: []
                },
                {
                    name: 'HTT',
                    toggled: false,
                    active: false,
                    children: []
                },
            ]
        },
        {
            name: 'Region 2',
            active: false,
            toggled: false,
            children: [{
                name: Gatwick North,
                active: false,
                toggled: false,
                children: []
            }]
        }
    ]
}

和给定的路径

['UK', 'Region 2', 'Gatwick North']

我如何设法为与上述数组匹配的嵌套对象中的路径将事件/切换属性添加为 true。

输出应该是这样的:

{
    name: 'UK',
    toggled: true,
    active: true,
    children: [{
            name: 'Region 1',
            active: false,
            toggled: false,
            children: [{
                    name: 'Heathrow T1',
                    toggled: false,
                    active: false,
                    children: []
                },
                {
                    name: 'HTT',
                    toggled: false,
                    active: false,
                    children: []
                },
            ]
        },
        {
            name: 'Region 2',
            active: true,
            toggled: true,
            children: [{
                name: 'Gatwick North',
                active: true,
                toggled: true,
                children: []
            }]
        }
    ]
}

我试图用递归来实现它，但到目前为止没有成功。我正在搜索问题，但没有一个符合我目前的情况。

Answer 1

使用递归的简单示例，解释在代码中作为注释

const obj = {name: 'UK',toggled: false,active: false,children: [{name: 'Region 1',active: false,toggled: false,children: [{name: 'Heathrow T1',toggled: false,active: false,children: []},{name: 'HTT',toggled: false,active: false,children: []},]},{name: 'Region 2',active: false,toggled: false,children: [{name: 'Gatwick North',active: false,toggled: false,children: []}]}]};

const checkAndChange = (obj) => { // function that will check if name exists in array and change toggle and active properties
  const arr = ['UK', 'Region 2', 'Gatwick North'];
  if (arr.includes(obj.name)) {
    obj.toggled = true;
    obj.active = true;
  }
}

const recursion = (obj) => {
   const o = obj;
   checkAndChange(o); // check if name exists in array and change toggle and active properties
   if (o.children.length > 0) { // check if has children
   		o.children.forEach(v => { // if has children do the same recursion for every children
      	recursion(v);
      });
   }
   return o; // return final new object
}

console.log(recursion(obj));
