vue+ts设置网页title

在router.js/router.ts中增加

router.beforeEach((to, from, next) => {
  /* 路由发生变化修改页面title */
  var Document:any = document;
  console.log(from, Document);
  if (to.meta.title) {
    Document.title = to.meta.title;
  }
  next()
})

在路由中设置

const routes = [
  {
    path: "/login",
    name: "LoginPage",
    meta: { requiresAuth: false, hideSidebar: true,title: '登录界面' }, 
    component: LoginPage,
  },
]

之前那些windows.document.title，都用不了，得先定义：var Document:any = document;
