数组中如何按照规则筛选对象？

Question

constrouter=[{path:'/hello',icon:'hammer',name:'hello',title:'你好',children:[{path:'index',title:'你好',name:'hello_index'},{path:'index1',title:'你好1',name:'hello_index1'}]},{path:'/hello1',icon:'hammer',name:'hello1',title:'你好',children:[{path:'index2',title:'你好2',name:'hello_index2'},{path:'index3',title:'你好3',name:'hello_index3'},{path:'index4',title:'你好3',name:'hello_index4'}]},{path:'/hello2',icon:'hammer',name:'hello2',title:'你好',children:[{path:'index4',title:'你好4',name:'hello_index4'},{path:'index5',title:'你好5',name:'hello_index5'}]}]letrouternone=[{path:'/hello2',children:[]},{path:'/hello1',children:['index2','index3']}];请问如何在router以routernone为规则筛选出新数组，routernone中表明，不取path为'/hello2'的，不取path为'/hello1'的children中path为index2的和path为index3的，

Answer 1

暴力筛选，能做的只是优化暴力程度；
letrouter=[
{
path:'/hello',
icon:'hammer',
name:'hello',
title:'你好',
children:[
{path:'index',title:'你好',name:'hello_index'},
{path:'index1',title:'你好1',name:'hello_index1'}
]
},
{
path:'/hello1',
icon:'hammer',
name:'hello1',
title:'你好',
children:[
{path:'index2',title:'你好2',name:'hello_index2'},
{path:'index3',title:'你好3',name:'hello_index3'},
{path:'index4',title:'你好3',name:'hello_index4'}
]
},
{
path:'/hello2',
icon:'hammer',
name:'hello2',
title:'你好',
children:[
{path:'index4',title:'你好4',name:'hello_index4'},
{path:'index5',title:'你好5',name:'hello_index5'}
]
}
]
letrouternone={
'/hello2':[],
'/hello1':['index2','index3']
}
router=router.filter((route,index)=>{
if(routernone[route.path]){
if(routernone[route.path].length>0){
route.children=route.children.filter((child)=>{
returnrouternone[route.path].indexOf(child.path)<=-1
})
returntrue
}else{
returnfalse
}
}else{
returntrue
}
})
console.log(router)

为什么要多加一个用于筛选的呢，直接在第一个对象列表中加标志不就好了，
constrouter=[
{
path:'/hello',
icon:'hammer',
name:'hello',
title:'你好',
children:[
{path:'index',title:'你好',name:'hello_index'},
{path:'index1',title:'你好1',name:'hello_index1'}
]
},
{
path:'/hello1',
icon:'hammer',
name:'hello1',
title:'你好',
children:[
{path:'index2',title:'你好2',name:'hello_index2',meta:{noshow:true}},
{path:'index3',title:'你好3',name:'hello_index3',meta:{noshow:true}},
{path:'index4',title:'你好3',name:'hello_index4'}
]
},
{
path:'/hello2',
icon:'hammer',
name:'hello2',
title:'你好',
meta:{noshow:true},
children:[
{path:'index4',title:'你好4',name:'hello_index4'},
{path:'index5',title:'你好5',name:'hello_index5'}
]
}
]
在运行时判断一下meta里的noshow是true,就不显示不就好了
