导航不允许重复导航到当前位置（“/搜索”）

当我想多次进行搜索时，它会向我显示错误。我的搜索位于导航栏中，我配置搜索的方式是使用模型获取值，然后将该值作为参数传递给 ContentSearched 组件，然后接收该组件中的搜索值。NavigationDuplicated

我知道正确的方法是使用发射器，但我仍然不知道如何学习使用它。要访问发出的是context.emit('', someValue)

NavigationDuplicated {_name: "NavigationDuplicated", name: "NavigationDuplicated", message: "Navigating to current location ("/search") is not allowed", stack: "Error↵    at new NavigationDuplicated (webpack-int…node_modules/vue/dist/vue.runtime.esm.js:1853:26)"}

答案 1

当我有一条指向同一条路线时，这发生在我身上。例如.router-link/products/1

用户可以单击产品，但如果已经单击了产品（并且组件视图已加载），并且用户尝试再次单击它，则控制台中将显示错误/警告。

您可以了解有关github问题的更多信息。

Posva是vue-router的主要贡献者之一，他建议：

router.push（'your-path'）.catch（err => {}）

但是，如果您不希望有一个什么都不做的块，为了解决问题，您可以将路由器导航与当前路由进行比较，并且仅在它们不同时才导航：catch

const path = `/products/${id}`
if (this.$route.path !== path) this.$router.push(path)

注意：是 vue 路由器提供给每个组件的对象。有关详细信息，请参阅路由对象。$route

答案 2

我认为，如果我们不打算进一步用作异步调用，则可以在根级别实现此问题的最佳解决方案。Router.push

import Router from 'vue-router';

const originalPush = Router.prototype.push;
Router.prototype.push = function push(location) {
  return originalPush.call(this, location).catch(err => err)
};

Vue.use(Router);
