javascript - 如何使用回车键将项目添加到输入中，并且仅在单击按钮时提交表单？

Question

我正在使用 v-select，但这个插件有问题...当您在输入中按 enter 时，它会提交到表单。如何使用 Enter 将项目添加到输入中，并且仅在单击按钮时提交表单？

Example Here CODE PEN

HTML

<div id="app">
  <h1>Vue Select</h1>
  <p>Try to add items in input using "ENTER"</p>
  <form v-on:submit.prevent="submited()">
  <v-select multiselect :options="options"></v-select>
    <button type="submit">Submit</button>
  </form>
</div>

JS

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

new Vue({
  el: '#app',
  data: {
    options: ["some", "thing", "another", "things"]
  },
  methods: {
    submited(){
      alert('submited!')
    }
  }
})

谢谢!!

我会阻止表单上的默认设置，然后将提交的逻辑移至按钮。

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

new Vue({
  el: '#app',
  data: {
    options: ["some", "thing", "another", "things"]
  },
  methods: {
    submitted() {
      console.log('submited!')
    }
  }
})

body {
  font-family: 'Open Sans', sans-serif;
}

#app {
  max-width: 35em;
  margin: 1em auto;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.3.4/vue.min.js"></script>
<script src="https://unpkg.com/vue-select@2.2.0/dist/vue-select.js"></script>
<div id="app">
  <h1>Vue Select</h1>
  <p>Try to add items in input using "ENTER"</p>
  <form v-on:submit.prevent="">
    <v-select multiple :options="options"></v-select>
    <button type="button" v-on:click="submitted()">Submit</button>
  </form>
</div>
