Vue 路由器工作不规律

Question

我花了一整天的时间试图弄清楚是什么让这个例子失败了：

Vue.use(VueRouter);
var PlayerDetail =  {
  template: '<div>FOO</div>'
};
var PlayerList =  {
  template: '<div>BAR</div>'
};
var routes = [{
  path: '/player',
  component: PlayerList
}, { 
  path: '/detail',
  component: PlayerDetail
}];
var appRouter = new VueRouter({
  routes
});
var appVm = new Vue({
  appRouter
}).$mount('#app');

<script src="https://unpkg.com/vue/dist/vue.js"></script>
<script src="https://unpkg.com/vue-router/dist/vue-router.js"></script>
<div id="app">
  <h1>Hello App!</h1>
  <p>
    <router-link to="/player">foo</router-link>
    <router-link to="/detail">bar</router-link>
  </p>
  <router-view></router-view>
</div>

如果它与这个完全一样有效：

Vue.use(VueRouter);
var Foo = {
  template: '<div>FOO</div>'
};
var Bar = {
  template: '<div>BAR</div>'
};
var routes = [{
  path: '/foo',
  component: Foo
}, {
  path: '/bar',
  component: Bar
}];
var router = new VueRouter({
  routes
});
var appVm = new Vue({
  router
}).$mount('#app');

<script src="https://unpkg.com/vue/dist/vue.js"></script>
<script src="https://unpkg.com/vue-router/dist/vue-router.js"></script>
<div id="app">
  <h1>Hello App!</h1>
  <p>
    <router-link to="/foo">foo</router-link>
    <router-link to="/bar">bar</router-link>
  </p>
  <router-view></router-view>
</div>

如您所见，这两个示例实际上是相同的代码，但是在第一个示例中，我得到了TypeError：路由器渲染时未定义路由。

还有其他人看到我在这里缺少的东西吗？

Answer 1

您正在传递Vue构造函数{ appRouter }，这是{ appRouter: appRouter }的简写。构造函数Vue需要具有 router 属性的对象，而不是具有 appRouter 属性的对象。

如果要

使用 object 属性速记传入路由器对象，则需要准确命名路由器对象router：

Vue.use(VueRouter);
var PlayerDetail =  {
  template: '<div>FOO</div>'
};
var PlayerList =  {
  template: '<div>BAR</div>'
};
var routes = [{
  path: '/player',
  component: PlayerList
}, { 
  path: '/detail',
  component: PlayerDetail
}];
var router = new VueRouter({
  routes
});
var appVm = new Vue({
  router
}).$mount('#app');

<script src="https://unpkg.com/vue/dist/vue.js"></script>
<script src="https://unpkg.com/vue-router/dist/vue-router.js"></script>
<div id="app">
  <h1>Hello App!</h1>
  <p>
    <router-link to="/player">foo</router-link>
    <router-link to="/detail">bar</router-link>
  </p>
  <router-view></router-view>
</div>

我认为路径和组件组合不正确

var routes = [{
  path: '/player',
  component: PlayerDetail
}, { 
  path: '/detail',
  component: PlayerList
}];
