尝试在vue.js中使用clear()清除表单时出现Typescript错误

data() {
  return {
    formData: {
      username: '',
      password: '',
      email: ''
    }
  }
}

<input type="text" v-model="formData.username" />
<input type="password" v-model="formData.password" />
<input type="email" v-model="formData.email" />
<button @click="resetForm">清除表单</button>

methods: {
  resetForm() {
    this.formData = {
      username: '',
      password: '',
      email: ''
    }
  }
}
