我有一个数组,每个项目都是一个具有唯一ID的对象.有些项目也可能有子项,并且它可以在子数组中包含子数组.我正在尝试使用Id选择一个项目.

           const array = [
                {
                    uuid: '40E75F3DE56B4B11B3AFBDE46785737B'
                }, {
                    uuid: '9CEF74766BBB4B9682B7817B43CEAE48'
                }, {
                    uuid: '34F209A883D3406FBA6BACD9E07DB1D9',
                    children: [{
                        uuid: 'F429C51BF01C405DA517616E0E16DE4E',
                        children: [{
                            uuid: '8823CFCE7D4645C68991332091C1A05C'
                        }, {
                            uuid: '58A9345E881F48C980498C7FFB68667D'
                        }]
                    }]
                }, {
                    uuid: '152488CC33434A8C9CACBC2E06A7E535'
                }, {
                    uuid: '9152B3DEF40F414BBBC68CACE2F5F6E4'
                }, {
                    uuid: 'B9A39766B17E4406864D785DB6893C3D'
                },
                {
                    uuid: '3J4H4J5HN6K4344D785DBJ345HSSODF',
                    children: [
                        {
                            uuid: 'EAB14DD72DA24BB88B4837C9D5276859'
                        },
                        {
                            uuid: 'FFA80D043380481F8835859A0839512B'
                        },
                        {
                            uuid: '9679687190354FA79EB9D1CA7B4962B1'
                        }
                    ]
                }
            ]

下面的代码适用于没有子代的简单数组.我需要一个函数,或者一个lodash模块,它可以递归搜索整个数组并返回对象(数组中的项)

findContainingObject(array, uuid) {
    let result = [];
    result = array.filter( item => {
        return item.uuid === uuid
    })
    return result;
}

预期产出：

findContainingObject(array, '40E75F3DE56B4B11B3AFBDE46785737B')

               {
                 uuid: '40E75F3DE56B4B11B3AFBDE46785737B'
               }

findContainingObject(array, '34F209A883D3406FBA6BACD9E07DB1D9')
                {
                    uuid: '34F209A883D3406FBA6BACD9E07DB1D9',
                    children: [{
                        uuid: 'F429C51BF01C405DA517616E0E16DE4E',
                        children: [{
                            uuid: '8823CFCE7D4645C68991332091C1A05C'
                        }, {
                            uuid: '58A9345E881F48C980498C7FFB68667D'
                        }]
                    }]
                }

findContainingObject(array, '58A9345E881F48C980498C7FFB68667D')

                 {
                    uuid: '58A9345E881F48C980498C7FFB68667D'
                 }

解决方法:

该函数实现DFS：

function findDFS(objects, id) {
  for (let o of objects || []) {
    if (o.uuid == id) return o
    const o_ = findDFS(o.children, id)
    if (o_) return o_
  }
}

和BFS：

function findBFS(objects, id) {
  const queue = [...objects]
  while (queue.length) {
    const o = queue.shift()
    if (o.uuid == id) return o
    queue.push(...(o.children || []))
  }
}
