<script>
export default {

data () {
return {
// 上传附件
fileList: [{

  //   name: 'food.jpeg',

  }
]

}
}
methods: {
// 上传附件
handleChange(file, fileList) {
this.fileList = fileList.slice(-3);
},
// 绑定回车键和发送按钮，以及不能发送空白消息

messageInput (e) {
  let vm = this  
  let msg = vm.msg.replace(/^\s+|\s+$/g, '');
  let oTest = document.getElementById('test');
  if(msg=='' && (e.which === 13 || e.target.classList.contains('send1'))){
    oTest.value = ''   //输入框是div的用
    vm.warn1 = true
    setTimeout(() => {
      vm.warn1 = false
    }, 1000)
  }else{
    if ((e.which === 13 && vm.msg) || (e.target.classList.contains('send1') && vm.msg)) {
      e.preventDefault()
      socket.emit('message', vm.currentRoomID, msg)
      vm.msg = ''
      // oTest.value = ''   //输入框是div的用
    }
  }
},

}
}

<input type="hidden" v-model="inputValue">

<el-upload ... on-success="success_handle" ... />

data(){
return {

inputValue:''

}
},
methods:{
...
success_handle(response,file,fileList) {

//根据将response返回的值赋值给inputValue
this.inputValue = response.YOUR_FIELDS

}
...
}
