I'm working on a custom input component which has a parent div and a label. I'd like to apply any classes to the parent div but I also want to make sure that any other fallthrough attributes get applied to the input component.

Here's a simplified version of my component

In App.vue

<script setup>
import { ref } from 'vue'
import MyInput from './MyInput.vue'

const msg = ref('I only want the outer blue box')
</script>

<template>
  <h1>{{ msg }}</h1>
  <my-input class="blue" aria-foo="foo" aria-bar="bar"/>
</template>

<style>
  .blue {
    padding: 1rem;
    border: 3px solid blue;
  }
</style>

In MyInput.vue

<template>
  <div :class="attrs.class">
    <input v-bind="attrs" >
  </div>
</template>

<script>
export default {
  inheritAttrs: false,
  customOptions: {}
}
</script>

<script setup>
 import { useAttrs, computed } from 'vue'
 const attrs = useAttrs();
</script>

Is there a good way to get all the attrs except for the class? I tried making a copy of attrs using a computed but that didn't seem to work.

This is what I tried:

const inputAttrs = computed(()=>{
  let returnObj = {}
  for (attr in attrs) {
    if (attr !== 'class') {
      returnObj[attr] = attrs[attr]
    }
  }
  return returnObj;
})

Apparently attr in the for loop was not defined? Essentially I want the input to get the aria-foo and aria-bar attributes without the class property.

Here's a Link to the SFC Playground with the above code.
