Why do you want to add one more for filtering? just add a flag to the first object list.
const router = [
{
path: '/hello',
icon: 'hammer',
name: 'hello',
title: '',
children: [
{ path: 'index', title: '', name: 'hello_index' },
{ path: 'index1', title: '1', name: 'hello_index1' }
]
},
{
path: '/hello1',
icon: 'hammer',
name: 'hello1',
title: '',
children: [
{ path: 'index2', title: '2', name: 'hello_index2',meta: {noshow:true} },
{ path: 'index3', title: '3', name: 'hello_index3' ,meta: {noshow:true}},
{ path: 'index4', title: '3', name: 'hello_index4' }
]
},
{
path: '/hello2',
icon: 'hammer',
name: 'hello2',
title: '',
meta: {noshow:true},
children: [
{ path: 'index4', title: '4', name: 'hello_index4' },
{ path: 'index5', title: '5', name: 'hello_index5' }
]
}
]
it would be nice to judge that the noshow in meta is true, at run time.
violence screening, all we can do is to optimize the degree of violence;
