Vue Router 无法正常工作并添加了 #

Question

我有一个带有搜索栏的主应用页面组件。返回的搜索结果在卡片中，我希望设置一个“单击此处查看更多详细信息”，将放置在每张卡片中。它将链接到单击的一个结果的详细信息页面。如何在 Vue 上链接这些组件以及是否可以传递 id？我希望单击按钮后，组件会在同一页面上呈现，而不是在新选项卡上呈现。

单击“单击此处”后，它会将链接更新为http://localhost:8081/#/{name:'Details',%20params:%20{id:%20result._gddid}}

和

我收到 [Vue 警告]：属性或方法“结果”未在实例上定义，但在渲染期间被引用。

谢谢！

单击“单击此处”后，它会将链接更新为http://localhost:8081/#/{name:'Details',%20params:%20{id:%20result._gddid}}

浏览一下代码，在 ArticleListItem.vue 中似乎没有绑定路由器链接的 to 属性，因此它被视为字符串。

目前：to="{name:'Details', params: {id: result._gddid}}"

试试：:to="{name:'Details', params: {id: result._gddid}}"，让它作为对象传递。

我收到 [Vue 警告]：属性或方法“结果”未在实例上定义，但在渲染期间被引用。

在 Details.vue 中，您有 props: ['result'],，但在 v-for 中它会查找未在 results 中定义的 results em>data() 也不在 props 内。

至于出现的#，vue-router的默认模式是hash，如果你不想使用#，你可以通过以下方式将其设置为history：

const router = new VueRouter({
  mode: 'history',
  routes: [...]
})

但请注意，您需要运行服务器来处理路由；你可以在https://router.vuejs.org/guide/essentials/history-mode.html#html5-history-mode找到更多信息
