Vue $attrs & inheritAttr实现button禁用效果案例

<template>
 <div>
  <button :disabled="$attrs.disabled">点击</button>
 </div>
</template>
 
<script>
 export default {
   inheritAttrs: false,
 }
</script>
 
<style scoped> 
</style>

<template>
 <div id="app">
 <Parent></Parent>
 <Button disabled></Button>
 </div>
</template>

<script>
import Parent from './components/Parent'
import Button from './components/Button';
 
export default {
 name: 'App',
 components: {
 Parent,
 Button
 }
}
</script>

<style>
#app {
 font-family: Avenir, Helvetica, Arial, sans-serif;
 -webkit-font-smoothing: antialiased;
 -moz-osx-font-smoothing: grayscale;
 text-align: center;
 color: #2c3e50;
 margin-top: 60px;
}
</style>

<template>
  <div class="inputCom-wrap">
    <input v-bind="$attrs" />
  </div>
</template>
 
<script lang="ts">
import { defineComponent } from 'vue'
 
export default defineComponent({
  inheritAttrs:false,//不希望根直接继承特性，而是使用$attrs自定义继承，当前组件的根就是inputCom-wrap
  setup () {
    return {}
  }
})
</script>
 
<style scoped> 
</style>
