Vue.如何在切换单选按钮时清除输入文件字段(验证组件v- file - input )？

<template>
  <div>
    <input type="radio" value="option1" v-model="selectedOption" @change="clearFileInput">
    <input type="radio" value="option2" v-model="selectedOption" @change="clearFileInput">
    <input type="file" ref="fileInput">
  </div>
</template>

<script>
export default {
  data() {
    return {
      selectedOption: ''
    };
  },
  methods: {
    clearFileInput() {
      this.$refs.fileInput.value = '';
    }
  }
};
</script>
