父级找子集直接点就行了,子集找父级呢?怎么操作
let arrn=[
{
"MENU_URL": "dashboard",
"MENU_ID": "104a580029c54e139210b7e87dca6d89",
"MENU_NAME": "监控面板"
},
{
"MENU_URL": "systemManage",
"MENU_ID": "769130d1918d47219e6f0c463a1c9c67",
"MENU_NAME": "系统管理"
},
{
"MENU_URL": "serviceManage",
"MENU_ID": "8619ca0b6fbc42649a27475e339d5d4a",
"MENU_INFO": [
{
"MENU_URL": "userInfo",
"MENU_ID": "104a580029c54e139210b7e87dca6d89",
"MENU_NAME": "三户信息"
}
],
"MENU_NAME": "业务管理"
},
{
"MENU_URL": "serviceManage/recordQuery",
"MENU_ID": "d379e3f38cb3472ab18287034f32ef46",
"MENU_INFO": [
{
"MENU_URL": "dashboard",
"MENU_ID": "104a580029c54e139210b7e87dca6d80",
"MENU_INFO": [
{
"MENU_URL": "dashboard",
"MENU_ID": "454a580029c54e139210b7e87dca6d82",
"MENU_NAME": "监控面板222"
}
],
"MENU_NAME": "监控面板111"
},
{
"MENU_URL": "dashboard",
"MENU_ID": "104a580029c54e139210b7e87dca6d89",
"MENU_NAME": "监控面板333"
}
],
"MENU_NAME": "订购信息查询"
}
]
知道监控面板222的MENU_ID,要找到最外层的MENU_ID
现在写了一个能从第二级找到第一级
```
function getParentId(childId) {
tmparr.forEach(function (item, index) {
if (item.MENU_INFO) {
item.MENU_INFO.forEach(function (list, idx) {
if (list.MENU_ID === childId) {
console.log('d', item)
}
})
}
})
}
getParentId('104a580029c54e139210b7e87dca6d80')
```
有没有高手可以改造一下,用递归什么的,查不定级数的
