如何在选择新选项时将输入数字重置为0？

function resetInput() {
  document.getElementById("inputField").value = 0;
}

<div id="app">
  <input v-model="inputNumber" type="number">
  <button @click="resetInput">选择新选项</button>
</div>

<script>
new Vue({
  el: '#app',
  data: {
    inputNumber: 0
  },
  methods: {
    resetInput() {
      this.inputNumber = 0;
    }
  }
});
</script>
