的嵌套數組的值。這是我的實際數組：如何更新對象
let mainArray= [
{
value: '/AG_TURF-123',
label: 'Ag & Turf',
checked: false,
id:123,
children: [
{
value: '/AG_TURF-123/TRACTOR-456',
label: 'Tractors',
checked: false,
id:456,
children: [
{
value: '/AG_TURF-123/TRACTOR-456/Large-7-8-9-series',
label: 'Large (7, 8, 9) Series',
checked: false,
id:789,
children: [{
value: '/AG_TURF-123/TRACTOR-456/Large-7-8-9-series/7-family-tractor',
label: '7 Family Tractor',
checked: false,
id:101112
},{
value: '/AG_TURF-123/TRACTOR-456/Large-7-8-9-series/8-family-tractor',
label: '8 Family Tractor',
checked: false,
id:131415
},{
value: '/AG_TURF-123/TRACTOR-456/Large-7-8-9-series/9-family-tractor',
label: '9 Family Tractor',
checked: false,
id:161718
}],
},
{
value: '/app/Http/routes.js',
label: 'routes.js',
checked: false,
id:181920
},
],
},
{
value: '/app/Providers',
label: 'Providers',
checked: false,
id:212223,
children: [{
value: '/app/Http/Providers/EventServiceProvider.js',
label: 'EventServiceProvider.js',
checked: false,
id:242526
}],
},
],
},
{
value: '/config',
label: 'config',
checked: false,
id:272829,
children: [
{
value: '/config/app.js',
label: 'app.js',
checked: false,
id:303132
},
{
value: '/config/database.js',
label: 'database.js',
checked: false,
id:333435
},
],
},
{
value: '/public',
label: 'public',
checked: false,
id:353637,
children: [
{
value: '/public/assets/',
label: 'assets',
checked: false,
id:383940,
children: [{
value: '/public/assets/style.css',
label: 'style.css',checked: false,
id:404142
}],
},
{
value: '/public/index.html',
label: 'index.html',
checked: false,
id: 434445
},
],
},
{
value: '/.env',
label: '.env',
checked: false,
id: 464748
},
{
value: '/.gitignore',
label: '.gitignore',
checked: false,
id: 495051
},
{
value: '/README.md',
label: 'README.md',
checked: false,
id: 525354
},
];
這就是我的價值列表：
const ids=[525354,123,131415];
我想設置checked到true如果ID匹配。 我的主陣列可能會達到6到7步深。
我做了什麼，直到尚未：
setCheckedFlagToItems(checkList, items) {
return items.map((item) => {
const node = item;
if (checkList.indexOf(node.id) !== -1) {
node.checked = true;
}
if ((node.children) && (Array.isArray(node.children) && node.children.length > 0)) {
this.setCheckedFlagToItems(checkList, node.children);
}
return node;
}, this);
}
但它不工作如常。
@Kris霍倫貝克，您的編輯並沒有真正檢查數組，如果它是一個或者不進行遞歸迭代，這是必要的。 –
嗯..也許我看錯了。它在我的IDE中拋出一個錯誤。舊的代碼是'Array.isArray（（a.children）&& a.children.forEach（callback）;''我得到''''''期望。所以缺少一個括號。 –
也許它應該是'Array.isArray（a.children）&& a.children.forEach（iter）;'？ –
