如何在vue.js 2中重置模式上的输入数据？

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

<input v-model="formData.name" type="text" placeholder="Name">
<input v-model="formData.email" type="email" placeholder="Email">
<input v-model="formData.password" type="password" placeholder="Password">

methods: {
  resetForm() {
    Object.keys(this.formData).forEach(key => {
      Vue.set(this.formData, key, '');
    });
  }
}

<button @click="resetForm">Reset</button>
