Question

HTML：

<select v-model="facilitySelected" name="facilities" multiple="multiple" id="facilities" size="4" class="form-control">
  <option value="1">Double (Non a/c)</option>
  <option value="2">Premium Double (a/c)</option>
  <option value="3">Standard Double (a/c)</option>
</select>

点击活动：

<a @click="addFacilities" class="btn btn-default add_option" rel="facilities2" id="add"><i class="fa fa-arrow-right"></i></a>

脚本：

export default {
  data(){
            return{
                facilitySelected:[]
            }
  }

  methods: {
      addFacilities() {
        this.facilitySelected;
        console.log(this.facilitySelected);
      }
  }
}

这里我有一个选择列表，当我点击addFacilities时，所选选项的value仅作为console.log的输出，我需要同时拥有value和text在通过console.log出来的选项中。当我点击value时，如何获得text和addFacilities？

在Vue中，您的value可能是一个复杂的对象。

在此示例中，值是同时包含文本和值的对象。选择它们后，您可以看到facilitySelected中都可以使用它们。

console.clear()


new Vue({
  el: "#app",
  data: {
    facilitySelected: []
  }
})

<script src="https://unpkg.com/vue@2.2.6/dist/vue.js"></script>
<div id="app">
  <select v-model="facilitySelected" name="facilities" multiple="multiple" id="facilities" size="4" class="form-control">
  <option :value="{value: 1, text:'Double (Non a/c)'}">Double (Non a/c)</option>
  <option :value="{value: 2, text:'Premium Double (a/c)'}">Premium Double (a/c)</option>
  <option :value="{value: 3, text:'Standard Double (a/c)'}">Standard Double (a/c)</option>
</select>
  <hr> Selected: {{facilitySelected}}
</div>

但是，您可以通过将选项存储在数据中来简化并避免重复自己。

console.clear()


new Vue({
  el: "#app",
  data: {
    facilitySelected: [],
    options: [{
        value: 1,
        text: 'Double (Non a/c)'
      },
      {
        value: 2,
        text: 'Premium Double (a/c)'
      },
      {
        value: 3,
        text: 'Standard Double (a/c)'
      }
    ]
  }
})

<script src="https://unpkg.com/vue@2.2.6/dist/vue.js"></script>
<div id="app">
  <select v-model="facilitySelected" name="facilities" multiple="multiple" id="facilities" size="4" class="form-control">
  <option v-for="option in options" :value="option">{{option.text}}</option>
</select>
  <hr> Selected: {{facilitySelected}}
</div>

如何从vue js中的select中获取值和文本？
