Now the scanner head of the pda is broadcasting

the reference answer GPT ᴼ ᴾ ᴱ ᴺ ᴬ ᴵ < br / > in Vue, you can through the window object to access the browser's native API, including native. The API in js. Therefore, it is also possible to use native.js in Vue to register broadcasts that receive scan results.

Specifically, you can register a broadcast receiver by calling the API in native.js in the mounted() lifecycle hook function of a Vue component, for example:

mounted() {
  if (window.plus) {  // 判断是否在移动端环境下
    var receiver = window.plus.android
      .broadcast
      .getBroadcastReceiver("your_action_name", "your_category_name");

    receiver.addEventListener("receive", function (event) {
      // 处理接收到的广播
      console.log(event);
    });

    // 注册广播接收器
    window.plus.android.broadcast.registerReceiver(receiver, null);
  }
}

In the above code, first determine if you are currently in a mobile environment, then create a broadcast receiver object and set the received broadcast action and broadcast label. Next, an event listener is registered to handle the received broadcast using the addEventListener() method. Finally, the registerReceiver() method is used to register the broadcast receiver.

Note that the code above only works on Android devices. If you need to implement similar functionality on an IOS device, you may need to use a different API to register your broadcast receiver.
