The most common use case for passing arguments to your events is when you want a child component to be able to set a specific value for its prop. Youneverwant to directly edit the value of a prop from the compo
It would be nice if it was possible to pass arbitrary data to a component via a data object. this.$router.go({name: '/signout', data: {message: 'Token expired'}}); Which would then be available to the component in the usual format.
It would be great if we could use v-bind with an object of attributes to pass props to a component. Currently we need to explicitly state the props we are passing to the component. <component is="component" :prop-a="propA" :prop-b="propB"></component> Good idea! And another shorth...

命名视图,从名称上看可能无法阐述的很清楚,与命名路由的实现方式相似,命名视图通过在 router-view 标签上设定 name 属性,之后,在构建路由与组件的对应关系时,以一种 name:component 的形式构造出一个组件对象,从而指明是在哪个 router-view 标签上加载什么组件。
Functional template works pretty much like React functional component: const header = props =>{{props.header}} Just in Vue, you just need to add 'functional' directive to the <template>, don't need to add any js code. exports those componets...
Components with slots can expose their data by passing it into the slot and exposing the data usingslot-scopein the template. This approach allows you to pass props down from Parent components to Child components without coupling them together. ...
