文章介绍了如何在PDA设备上使用JavaScript实现对多种广播事件的监听，包括扫码结果，以便于处理不同厂商的设备扫描数据。函数`recive`负责接收广播并处理数据，`unregisterReceiver`用于取消监听。

pda 设备上用广播监听扫码

可以用于其他广播监听

var main = null;
var receiver = null;
//接收广播
function recive(success, fail) {

	// #ifdef APP





	main = plus.android.runtimeMainActivity(); //获取activity
	//创建自定义广播实例  
	receiver = plus.android.implements('io.dcloud.feature.internal.reflect.BroadcastReceiver', {
		onReceive: function(context, intent) { //实现onReceiver回调函数  
			plus.android.importClass(intent); //通过intent实例引入intent类，方便以后的‘.’操作  
			var action = intent.getAction()

			var data
			switch (action) {
				case "com.android.server.scannerservice.broadcast":
					data = intent.getExtra("scannerdata");
					break

				case "android.intent.action.SCANRESULT":
					data = intent.getExtra("value");
					break

				case "android.intent.ACTION_DECODE_DATA":
					data = intent.getExtra("barcode_string");
					break

				case "com.android.provider.sdlmessage":
					data = intent.getExtra("msg");
					break
				case "com.neusoft.action.scanner.read":

					data = intent.getStringExtra("scanner_value"); //东软pda
					if (data == null) {
						data = intent.getStringExtra("Scanner_value"); //东软pda
					}
					break
				case "nlscan.action.SCANNER_RESULT":
					data = intent.getExtra("SCAN_BARCODE1");
					break
				case "com.barcode.sendBroadcast":
					data = intent.getExtra("BARCODE");
					break

				case "scan.rcv.message":


					let barocode = intent.getByteArrayExtra("barocode");
					let barocodelen = intent.getIntExtra("length", 0);
					data = new String(barocode, 0, barocodelen);

					break

				case "xlyk.wz":
					data = intent.getExtra("qrcode");
					break

				case "com.android.scanner.broadcast":
					data = intent.getExtra("scandata");
					break
				case "com.honeywell.scan.broadcast":
					data = intent.getExtra("data");
					break


			}
			if (data) {
				// console.log('zhanglp', data.replace(/\n/, ''))
				// console.log('zhanglp', data.replace(/\n/, '').replace(/\t/, ''))
				success({
					type: 'barcode',
					data: data.replace(/\n/, '').replace(/\t/, '').trim() //处理结束符和换行符为空
				})
			} else {

				fail({
					type: 'barcode',
					data: '未识别到扫码数据' //处理结束符和换行符为空
				})
			}


		}
	});
	var IntentFilter = plus.android.importClass('android.content.IntentFilter'); //网络
	var Intent = plus.android.importClass('android.content.Intent');
	var filter = new IntentFilter(); //过滤





	filter.addAction("com.android.provider.sdlMessage"); //海信
	filter.addAction("com.neusoft.action.scanner.read"); //东软
	filter.addAction("nlscan.action.SCANNER_RESULT"); //新大陆  霍尼韦尔
	filter.addAction("scan.rcv.message"); //南方鸿志
	filter.addAction("com.android.server.scannerservice.broadcast"); //得实2 东大集成  扫码工具密码888888
	filter.addAction("android.intent.action.SCANRESULT"); //得实idata
	//            filter.addAction("com.android.server.scannerservice.broadcast");//东大集成  扫码工具密码888888
	filter.addAction("android.intent.ACTION_DECODE_DATA"); //UROVO  优博讯科
	filter.addAction("com.barcode.sendBroadcast"); //西安富立叶微电子 F760
	filter.addAction("xlyk.wz"); //西安富立叶微电子 F760
	filter.addAction("com.android.scanner.broadcast");
	filter.addAction("com.android.scanner.broadcast");
	filter.addAction("com.honeywell.scan.broadcast");


	main.registerReceiver(receiver, filter); //注册监听
	// #endif
}
//取消监听
function unregisterReceiver() {
	// #ifdef APP
	console.log("取消监听广播")
	main.unregisterReceiver(receiver);
	// #endif
}


module.exports = {
	recive: recive,
	unregisterReceiver: unregisterReceiver
}

使用方法在监听的页面加入

import broReceiver from '../../utils/Broadcast.js'

   onShow() {

           broReceiver.recive(function(res) {
               console.log("setting....", JSON.stringify(res))

           }, function(err) {
               console.log("setting....", JSON.stringify(res))
           })

//记得页面隐藏或卸载关闭监听

onUnload: function() {
broReceiver.unregisterReceiver()
},
