Object is possibly ‘undefined‘ (2532) 2022/8/4am

menuList:[{ 
  path: '/contacts',
  name: 'contacts',
  component: () => import('@/views/Contacts/index.vue'),
  meta: {
    title: 'Contacts',
    icon: ' icon-contacts',
    iconActive: ' icon-contacts',
    hidden: false,
    ishowiconActive: false
   }
 },
 { 
  path: '/contacts',
  name: 'contacts',
  component: () => import('@/views/Contacts/index.vue'),
  meta: {
    title: 'Contacts',
    icon: ' icon-contacts',
    iconActive: ' icon-contacts',
    hidden: false,
    ishowiconActive: false
    }
  },
]


报错： data.menuList[i].meta.hidden = false


更正后：(data.menuList[i].meta as any).ishowiconActive = false
重点：为data.menuList[i].meta 指定类型
