vue wrap another component, passing props and events

问题

How can I write my component to wrap another vue component, while my wrapper component get some extra props? My wrapper template component should be:

<wrapper-component>
   <v-table></v-table> <!-- pass to v-table all the props beside prop1 and prop2 -->
</wrapper-component>

and the wrapper props:

props: {
  prop1: String,
  prop2: String
}

Here I want to wrap a table component, and pass to the table component all the props and events that were passed to the wrapper, beside two extra props prop1 and prop2. What is the correct way of doing this in vue? And is there a solution for events too?

回答1:

Place the component you wish to wrap into the template of the wrapper component, add v-bind="$attrs" v-on="$listeners" to that component tag, then add the inner component (and, optionally, inheritAttrs: false) to the wrapper component's config object.

Vue's documentation doesn't seem to cover this in a guide or anything, but docs for $attrs, $listeners, and inheritAttrs can be found in Vue's API documentation. Also, a term that may help you when searching for this topic in the future is "Higher-Order Component" - which is basically the same as your use of "wrapper component". (This term is how I originally found $attrs)

For example...

<!-- WrapperComponent.vue -->
<template>
    <div class="wrapper-component">
        <v-table v-bind="$attrs" v-on="$listeners"></v-table>
    </div>
</template>

<script>
    import Table from './BaseTable'

    export default {
        components: { 'v-table': Table },
        inheritAttrs: false // optional
    }
</script>
