打印机打印标签
项目地址:https://github.com/dyl169/WAPP_printer.git有需要的可以参考一下 [图片] [代码]1.在需要调用蓝牙的页面中
初始化是传入设备的主服务UUID base.Ble.initBle(['FFF0', '0A71']);
2.在onLoad中执行监听函数(记得在onUnload中 remove掉事件监听)
//初始化所有监听
initListen: function() {
//监听蓝牙可用状态
base.Event.listen(base.EventModel.EVENT_BLESTATE, function(data) {
if (data.code) {
console.log('蓝牙已打开')
base.blestate = true;
} else {
console.log('蓝牙已关闭')
base.blestate = false;
}
})
//监听扫描设备
base.Event.listen(base.EventModel.EVENT_SCAN, function(data) {
if (data.stop) {
console.log('停止扫描');
that.setData({
bleSearchIng: false,
})
} else {
var device = data.datainfo[0];
console.log('扫描到的设备 : ' + JSON.stringify(device));
that.data.deviceArray.push(device);
that.setData({
deviceArray: that.data.deviceArray,
showDeviceDialog: true,
})
}
})
//监听蓝牙连接状态
base.Event.listen(base.EventModel.EVENT_CONNSTATE, function(data) {
console.log('连接状态变化');
if (data.code == true) {
console.log('index 连接成功')
for (var i = 0; i < that.data.deviceArray.length; i++) {
if (that.data.deviceArray[i].deviceId === data.datainfo) {
that.data.connDevice = that.data.deviceArray[i];
}
}
that.setData({
connSucced: true,
connDevice: that.data.connDevice,
})
} else {
that.setData({
connSucced: false,
})
}
})
//监听蓝牙值变化
base.Event.listen(base.EventModel.EVENT_RECEIVE, function(result) {
if (result.code == true && pageState == 'onLoad' || pageState == 'onShow') {
var data = result.datainfo;
console.log('main 页面接受到消息:' + data);
}
})
},
3.如果打印机无法打印 请查看打印机说明书 知否支持TSPL或ESC指令指令 (本demo使用的佳博答应机)
自行将PrintUtil.js中的打印指令修改为对应的打印指令即可[代码]
