腳本第n階樹 [英] JavaScript nth degree tree

問題描述

1. 如果所有單擊的子項都為True，則需要將父項的Clicked屬性更改為True。因此，在本例中，ID-14，15是將CLICKED屬性設置為True。因此，ID 11被點擊的父母必須成為真的。
2. 如果11、12、14、15為真，則必須使4為真。

let obj = {children:[
{
    ID:1,
    clicked: false,
    children: [
        {
            ID:4,
            clicked: false,
            children: [
                {
                    ID:11,
                    clicked: false,
                    children: [
                                {
                                    ID:14,
                                    clicked: true,
                                },
                                {
                                    ID:15,
                                    clicked: true,
                                }
                            ]
                },
                {
                    ID:12,
                    clicked: false,
                }
            ]
        },
        {
            ID:5,
            clicked: false,
        }
    ]
  }
 ]
}

推薦答案

Nina很好地回答了您何時要更改輸入。

下面是一個創建新對象的簡單方法：

const consolidate = ({clicked, children = [], ...rest}, _, __, kids = children .map (consolidate)) => ({
  ...rest, 
  clicked: clicked || (kids .length > 0) && kids .every (k => k .clicked),
  ...(kids .length ? {children: kids} : {})
})

const obj1 = {children: [{ID: 1, clicked: false, children: [{ID: 4, clicked: false, children: [{ID: 11, clicked: false, children: [{ID: 14, clicked: true}, {ID: 15, clicked: true}]}, {ID: 12, clicked: false}]}, {ID: 5, clicked: false}]}]};
//  with 12 switched to `true`
const obj2 = {children: [{ID: 1, clicked: false, children: [{ID: 4, clicked: false, children: [{ID: 11, clicked: false, children: [{ID: 14, clicked: true}, {ID: 15, clicked: true}]}, {ID: 12, clicked: true}]}, {ID: 5, clicked: false}]}]};

console .log ('obj1', consolidate (obj1))
console .log ('obj2', consolidate (obj2))

.as-console-wrapper {max-height: 100% !important; top: 0}
