NavigationDuplicated 导航到当前位置 (“/search") 是不允许的
[英] NavigationDuplicated Navigating to current location ("/search") is not allowed
本文介绍了NavigationDuplicated 导航到当前位置 (“/search") 是不允许的的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
当我想多次搜索时，它会向我显示 NavigationDuplicated 错误.我的搜索在导航栏中，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，然后在该组件中接收搜索值.
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.访问发射是 context.emit('', someValue)

解决方案
当我有一个 router-link 指向同一条路线时，这发生在我身上.例如/products/1.
<块引用>用户可以点击产品，但是如果产品已经被点击(并且组件视图已经加载)并且用户尝试再次点击它，错误/警告显示在控制台中.
您可以在 关于 github 问题了解更多信息..
vue-router 的主要贡献者之一 Posva 建议:
<块引用>router.push('your-path').catch(err => {})
但是，如果您不想有一个什么都不做的 catch 块，为了解决这个问题，您可以将路由器导航与当前路线进行比较并且仅在以下情况下进行导航它们不同:
const path = `/products/${id}`if (this.$route.path !== path) this.$router.push(path)
注意:$route 是 vue-router 提供给每个组件的对象.请参阅路由对象了解更多信息.
When I want to do a search multiple times it shows me the NavigationDuplicated error. My search is in the navbar and the way I have configured the search is to take the value using a model and then pass the value as a parameter to the ContentSearched component, and then receive the value of the search in that component.
I know the right way is to use an emitter, but I still don't know how to learn to use it. To access the emit is context.emit('', someValue)

解决方案
This happened to me when I had a router-link pointing to the same route. e.g. /products/1.
The user is able to click on the products, but if a product was already clicked (and the component view was already loaded) and the user attempts to click it again, the error/warning shows in the console.
You can learn more on the github issue..
Posva, one of the main contributors of vue-router suggests:
router.push('your-path').catch(err => {})
However, if you don't want to have a catch block which does nothing, in order to solve the issue you can compare the router navigation with the current route and only navigate if they differ:
const path = `/products/${id}`
if (this.$route.path !== path) this.$router.push(path)
Note: $route is an object provided by vue-router to every component. See The Route Object for more info.
