如果你只需要一个简单的页面路由,而不想为此引入一整个路由库,你可以通过动态组件的方式,监听浏览器 hashchange 事件或使用 History API 来更新当前组件。
下面是一个简单的例子:
<script>
import Home from './Home.vue'
import About from './About.vue'
import NotFound from './NotFound.vue'
const routes = {
'/': Home,
'/about': About
}
export default {
data() {
return {
currentPath: window.location.hash
}
},
computed: {
currentView() {
return routes[this.currentPath.slice(1) || '/'] || NotFound
}
},
mounted() {
window.addEventListener('hashchange', () => {
this.currentPath = window.location.hash
})
}
}
</script>
<template>
<a href="#/">Home</a> |
<a href="#/about">About</a> |
<a href="#/non-existent-path">Broken Link</a>
<component :is="currentView" />
</template>
