如下例子

父组件:

<attr-test first-name="aaa" last-name="bbb"></attr-test>

子组件

<template>
  <div @click="foo">{{ firstName }} {{ $attrs.lastName }}</div>
</template>

<script>
export default {
  name: 'attr-test',
  props: {
    firstName: String,
  },
  methods: {
    foo() {
      console.info(this.firstName) // aaa
      console.info(this.$attrs.lastName) // undefined
      console.info(this.$attrs['last-name']) // bbb
    }
  }
}
</script>
