Vue路由器工作效率

Question

我花了一整天的时间试图找出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>

​

如果它和这个一模一样的话：

​

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>

​

正如您所看到的，这两个示例实际上都是相同的代码，但在第一个示例中，我得到了TypeError:路由器呈现时没有定义路由。

还有人看到我在这里遗漏了什么吗？

Answer 1

您正在传递Vue构造函数{ appRouter }，它是{ appRouter: appRouter }的缩写。Vue构造函数期望对象具有router属性，而不是appRouter属性。

如果要使用object属性速记传递路由器对象router，则需要准确命名它：

​

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>

Answer 2

我认为路径和组件组合是不正确的。

​

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