JS基石之-----数组转换为树结构函数

我们常常在做后台管理系统的时候 需要对数据进行组装成一个树装结构，这里特地将此方法进行封装：

let data = [

    { id: , text: 't11', parentId:  },

    { id: , text: 't11', parentId:  },

    { id: , text: 't11', parentId:  },

    { id: , text: 't11', parentId:  },

    { id: , text: 't11', parentId:  },

    { id: , text: 't11', parentId:  }

]

function treeData (data, id, parentId, childName) {

    let cloneData = JSON.parse(JSON.stringify(data))

    return cloneData.filter((father) => {

        let newArr = cloneData.filter((child) => {

            return father[id] === child[parentId]

        })

        father[childName] = newArr

        return father[parentId] ===

    })

}

let msg = treeData(data, 'id', 'parentId', 'childaaa')

console.log(msg)
