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)"}
