javascript - 无法在 vue-select 上触发事件

Question

我正在使用 vue-select 从下拉列表中输入/选择，因此在选择任何选项时我试图获取所选的值

代码

<vueSelect 
       :clearable="false"
       v-on:change="itemCodeChange($event)"
       :options="itemCode">
</vueSelect>

脚本

    import vueSelect from 'vue-select'
    import 'vue-select/dist/vue-select.css';
    components :{
        vueSelect,

    },
  data () {
     return {
        itemCode:[],
     }      
  },
   methods:{
  itemCodeChange (a)
      {
          alert(a)
      }

当我改变时什么也没有发生

您需要使用输入事件而不是更改事件:请参阅工作代码

Vue.component('v-select', VueSelect.VueSelect)

new Vue({
  el: '#app',
  data: {
    options: [
      'foo',
      'bar',
      'baz'
    ]
  },
  methods: {
    changed(v) { console.log(v); }
  }
})

@import 'https://fonts.googleapis.com/css?family=Source+Sans+Pro:600';
@import 'https://unpkg.com/vue-select/dist/vue-select.css';

body {
  font-family: 'Source Sans Pro', 'Helvetica Neue', Arial, sans-serif;
}

h1 {
  font-size: 26px;
  font-weight: 600;
  color: #2c3e5099;
  text-rendering: optimizelegibility;
  -moz-osx-font-smoothing: grayscale;
  -moz-text-size-adjust: none;
}

#app {
  max-width: 30em;
  margin: 1em auto;
}

<div id="app">
  <h1>Vue Select</h1>
  <v-select :options="options" @input="changed"></v-select>
</div>
