vue.js - Vuejs v-on :click not working on option tag

Question

我正在尝试制作一个 vueapp，当用户点击一个选项标签时设置一个属性。我正在尝试使用 v-on:click 但它没有用。有什么想法吗？

<div v-show="loggedin==1" class="searchBy">
    <h2>Selected Display</h2>
    <select v-model="selectedDisplayShapeText">
        <option value="" disabled>Please Choose One</option>
        <option v-for="display in displays" :value="display.shapetext" v-on:click="displayName=display.name">{{display.name}}</option>
    </select>
</div>

您可以在 select 的 change 事件中检索选项:

new Vue({
  el: "#app",
  data() {
    return {
      displays: [{ name: "Display1", shapetext: "1" }, { name: "Display2", shapetext: "2" }, { name: "Display3", shapetext: "3" }],
      selectedDisplayShapeText: '',
      displayName: ''
    }
  },
  methods: {
    getDisplayName(e){
      let value = e.target.value
      let display = this.displays.find(d => d.shapetext == value)
      this.displayName = display.name
    }
  }
})

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.16/vue.min.js"></script>
<div id="app">
  <h2>Selected Display</h2>
  <select v-model="selectedDisplayShapeText" v-on:change="getDisplayName($event)">
    <option value="" disabled>Please Choose One</option>
    <option v-for="display in displays" :value="display.shapetext">{{display.name}}</option>
  </select>
  <p>Display selected: {{ displayName }}</p>
</div>
