项目主要是做的一个扫码的功能
核心代码为

 <div class="scan">
    <div id="bcid">
      <div style="height:40%"></div>
      <p class="tip">...载入中...</p>
    </div>
    <footer>
      <button @click="startRecognize">1.创建控件</button>
      <button @click="startScan">2.开始扫描</button>
      <button @click="cancelScan">3.结束扫描</button>
  &lt;button @click="closeScan"&gt;4.关闭控件&lt;/button&gt;
&lt;/footer&gt;

</div>
</template>
<script type='text/ecmascript-6'>
let scan = null
export default {
data () {
return {
codeUrl: '',
}
},
methods: {
// 创建扫描控件
startRecognize () {
let that = this
if (!window.plus) return
scan = new plus.barcode.Barcode('bcid')
scan.onmarked = onmarked
    function onmarked (type, result, file) {
      switch (type) {
        case plus.barcode.QR:
          type = 'QR'
          break
        case plus.barcode.EAN13:
          type = 'EAN13'
          break
        case plus.barcode.EAN8:
          type = 'EAN8'
          break
        default:
          type = '其它' + type
          break
      }
      result = result.replace(/\n/g, '')
      that.codeUrl = result
      alert(result)
      that.closeScan()

    }
  },
  // 开始扫描
  startScan () {
    if (!window.plus) return
    scan.start()
  },
  // 关闭扫描
  cancelScan () {
    if (!window.plus) return
    scan.cancel()
  },
  // 关闭条码识别控件
  closeScan () {
    if (!window.plus) return
    scan.close()
  },
}

}
