javascript - 如何在 Vue js 中将 Checkboxes 与 Chips 绑定(bind)(双向绑定(bind))

Question

我是 Vue Js 的新手。问题出在从表单中选择下拉菜单时，选项以 div 中复选框的形式出现，在选择复选框时，芯片应显示带有复选框标签。但这里会自动选中复选框并显示芯片，但在选择之后一个复选框筹码应该显示并且在关闭筹码复选框时应该取消选择。这是预期的但没有发生。这是我的代码。请帮助。

   <template>
    <div id="app">
     <v-layout row wrap>
         <v-flex v-for="chip in chips" xs12 sm4 md4>
          <v-checkbox   :label="chip.name" v-model="chip.text"></v-checkbox>
          //  checkbox not working
          </v-flex>
        <div class="text-xs-center">
       <v-select
       :items="dataArr"
        v-model="sensorDM"
       label="Select"
      class="input-group--focused"
     item-value="text"
     v-change="call(sensorDM)"
       ></v-select>
       <v-chip
          v-for="tag in chips"
          :key="tag.id"
          v-model="tag.text"
          close
        >
        {{ tag.name }}
        </v-chip> 
        <br>
        </div>
      </div>
    </template>
    <script>
    import axios from 'axios'
    export default {
      name: 'Creation',
      data: () => ({
       chips: [{
          id: 1, text: 'Device 1', name: 'Device 1'
        }, {
          id: 2, text: 'Device2', name: 'Device 2'
        }],
        chip1: false,
        chip2: true,
        dataArr: []
      }),
      created () {
        let self = this
        axios.get('http://localhost:4000/api/devices')
    .then(function (response) {
     self.fData(response.data.result)
    })
      },
      methods: {
      fData: function (message) {
      let self = this  
      message.forEach(function (el, i) {
        self.dataArr.push(el.sDM.name)
      })
    },
        call (mes) {
          let self = this
          axios.get('http://localhost:4000/api/part1/Models/' + mes)
    .then(function (res) {
      self.resObj = res.data.response
      self.resObj.forEach(function (el, i) {
        el['text'] = el.name
        el['isOpen'] = 'false'
      })
      self.chips = self.resObj
    })
        },
        submit(){
             console('hjkh')
        }    
      }
    }

您好，我已经编辑了代码并添加了来自 created() 的函数调用

我猜你想这样做 https://codepen.io/ittus/pen/VxGjgN

<div id="app">
   <v-flex v-for="chip in chips" :key="chip.id" xs12 sm4 md4>
      <v-checkbox :label="chip.name" v-model="chip.selected"></v-checkbox>
      <v-chip
         v-model="chip.selected"
         close>
         {{ chip.name }}
      </v-chip>
   </v-flex>
   <div class="text-xs-center">
   </div>
</div>

new Vue({
  el: '#app',
  data() {
    return {
      chips: [{
      id: 1, text: 'Device 1', name: 'Device 1', selected: false
    }, {
      id: 2, text: 'Device2', name: 'Device 2', selected: false
    }],
    chip1: false,
    chip2: true,
    }
  }
})

我添加了 selected 属性，因为默认情况下 v-checkbox 和 v-chip 值是 bool 值。
