How to scan with broadcast receiving pad through native.js in vue

This answer quotes ChatGPT

To use Native.js in Vue to scan with broadcast receiving Pad, follow the following steps:

Installing the Cordova plugin cordova-plugin-broadcaster:

cordova plugin add cordova-plugin-broadcaster
在 Vue 组件中使用插件：

javascript
Copy code
// 导入插件
import Broadcaster from 'cordova-plugin-broadcaster';

// 在 created 生命周期中添加监听事件
created() {
  Broadcaster.addEventListener('scannerdata', this.handleScannerData.bind(this));
},

// 在 destroyed 生命周期中删除监听事件
destroyed() {
  Broadcaster.removeEventListener('scannerdata', this.handleScannerData.bind(this));
},

// 处理扫描数据
methods: {
  handleScannerData(data) {
    console.log(data);
  }
}

To send a broadcast to the Native terminal:

// 创建 Intent 对象
Intent intent = new Intent();
intent.setAction("com.scanner.broadcast.ACTION");
intent.putExtra("data", "your_scanned_data");

// 发送广播
sendBroadcast(intent);

among them, "com. Scanner. Broadcast. The ACTION" is broadcast ACTION, can according to need custom;" your_scanned_data" is the scanned data and can be modified as needed.

This makes it possible to scan in Vue using a broadcast receiver Pad through Native.js.

1. Define a function in native.js to receive broadcast information and pass it back to the Vue component.

// native.js
function receiveScanResult(result) {
  window.vueInstance.$emit('scan-result', result);
}

2. In the Vue component, use the $on method to listen for the scan-result event to obtain the scan result sent from native.js.

// MyComponent.vue
export default {
  mounted() {
    window.vueInstance = this;
    this.$on('scan-result', (result) => {
      // 处理扫描结果
    });
  },
  methods: {
    // 触发扫描事件
    triggerScan() {
      window.nativeInstance.scan();
    },
  },
};

3. In native.js, use the BroadcastReceiver class to register broadcasts that receive scan results.

// native.js
const receiver = new BroadcastReceiver();
receiver.register('com.example.ACTION_SCAN_RESULT', (result) => {
  receiveScanResult(result);
});

4. On the Android platform, use sendBroadcast to broadcast scan results.

// MainActivity.java
private void sendScanResult(String result) {
  Intent intent = new Intent("com.example.ACTION_SCAN_RESULT");
  intent.putExtra("result", result);
  sendBroadcast(intent);
}

On the Pad device, load the web page containing the native.js and Vue components by scanning the QR code or manually entering the address.
After completing the above steps, when the user scans the barcode on the Pad device, the Android application will send a broadcast message, which native.js will receive and pass back to the Vue component, where you can eventually process the scan result.

It's my mistake. It's the scanning head of the pda scanner gun. How to use navite.js in vue?
