我试图使用vuejs3上的vue-路由器制作一个简单的路由器,并且在第一次单击链接(而不是其他的单击)时收到这个警告:
vue@next:1571 Vue警告:组件缺少模板或呈现函数。
我使用vuejs3,vue-路由器,vscode,chrome on ubuntu。
我的代码:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Warn - Vue 3 / Router</title>
</head>
<body>
<div id="app">
<router-link to="/">Home</router-link>
<br />
<router-link to="/contact">Contact</router-link>
<router-view></router-view>
</div>
<script src="https://unpkg.com/vue@next"></script>
<script src="https://unpkg.com/vue-router@4.0.5/dist/vue-router.global.js"></script>
<script>
// App
const app = Vue.createApp({});
// Component
const Home = app.component("home", {
template: `<h1>Home</h1>`,
name: "Home",
});
const Contact = app.component("contact", {
template: `<h1>Contact</h1>`,
name: "Contact",
});
// Router
const router = VueRouter.createRouter({
history: VueRouter.createWebHistory(),
routes: [
{ path: "/", component: Home },
{ path: "/contact", component: Contact },
],
});
app.use(router);
app.mount("#app");
</script>
</body>
</html>你能给我一个在vuejs3上实现vue路由器的链接(我是vuejs的初学者)吗?谢谢

有两个问题:
app.component("home", {
template: `<h1>Home</h1>`,
name: "Home",
});
const Home = app.component("home");请参阅:https://v3.vuejs.org/api/application-api.html#component
- history: VueRouter.createWebHistory(),
+ history: VueRouter.createWebHashHistory(),完整的代码如下:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />

<div id="app">

<br />
<router-link to="/contact">Contact</router-link>
<router-view></router-view>
</div>
<script src="https://unpkg.com/vue@next"></script>
<script src="https://unpkg.com/vue-router@4.0.5/dist/vue-router.global.js"></script>
<script>
// App
const app = Vue.createApp({});
// Component
app.component("home", {
template: `<h1>Home</h1>`,
name: "Home",
});
const Home = app.component("home");
app.component("contact", {
template: `<h1>Contact</h1>`,
name: "Contact",
});
const Contact = app.component('contact')
// Router
const router = VueRouter.createRouter({
history: VueRouter.createWebHashHistory(),
routes: [
{ path: "/", component: Home },
{ path: "/contact", component: Contact },
],
});
app.use(router);
app.mount("#app");
</script>
