问题

嗨，开发人员，

我有一个问题，当我想多次搜索时会显示NavigationDuplicated错误。我的搜索是在导航栏中，而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的值。

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。要访问发射是context.emit('', someValue)

如果有人可以帮助我解决问题，我将不胜感激。

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)"}
