获取keyup Vuejs 2的输入值

Question

我正在尝试使用Vuejs 2获取keyup的输入值，但总是得到像数据一样的空结果。请参阅下面的代码。

HTML：

iew = db.getView("Team Documents\\By Date"); 

脚本：

<input type="email" @keyup="this.$data.email= $event.target.value" class="form-control" id="email" placeholder="Username (your work email)">
<button type="button" class="btn btn-primary btn-block inactive" @click="submit">Log in</button>

Answer 1

您需要引用email（不是this.$data.email）：

<input type="email" @keyup="email = $event.target.value" class="form-control" id="email" placeholder="Username (your work email)">

但是，为什么不使用v-model将email绑定到输入？

new Vue({
  el: '#app',
  data () {
    return {
      email: '',
    }
  },
  methods: {
    submit () {
      alert(this.email)
    }
  }
})

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.4.2/vue.min.js"></script>
<div id="app">
  <input type="email" v-model="email" class="form-control" id="email" placeholder="Username (your work email)">
  <button type="button" class="btn btn-primary btn-block inactive" @click="submit">Log in</button>
</div>

Answer 2

@ keyup.enter.native =“ submitMETHOD”
