const NotFound = { template: '<p>Page not found</p>' }
const Home = { template: '<p>home page</p>' }
const About = { template: '<p>about page</p>' }
const routes = {
'/': Home,
'/about': About
}
new Vue({
el: '#app',
data: {
currentRoute: window.location.pathname
},
computed: {
ViewComponent () {
return routes[this.currentRoute] || NotFound
}
},
render (h) { return h(this.ViewComponent) }
})
ViewComponent 这个是什么?function么?为什么不带function关键字?
