其实很简单.
把原来demo中的 this, 改成 that即可.
下面是代码:
export default {
mixins: [Mixins],
data () {
let self = this
return {
// 身份证读卡器变量
socket: new WebSocket("ws://127.0.0.1:6688"),
sendFlag: 0,
zpFormat: ''
}
},
methods: {
//读取身份信息
readIDCard() {
this.zpFormat='' ;
this.sendFlag=3;
console.info('in readIDCard, this.sendFlag: ' + this.sendFlag);
try {
this.socket.send("SDT_ReadCard#"+this.zpFormat+"#");
console.info('== this.socket sent')
}
catch (ex) {
console.error(ex)
console.info("请打开设备.");
}
},
// 调用这个来读取身份证信息，并把信息填入到表单中
scanIdCard () {
this.openReader()
this.sendFlag = 3
console.info('in scanIdCard, this.sendFlag: ' + this.sendFlag);
let that = this
setTimeout(function(){ that.readIDCard() }, 500)
setTimeout(function(){ that.closeReader() }, 3000)
},
//连接设备
openReaderStart() {
this.sendFlag=2;
this.socket.send("SDT_OpenReader#");
},
//关闭设备
closeReader() {
this.sendFlag=4;
try {
this.socket.send("SDT_CloseReader#");
}
catch (ex) {
console.error(ex)
console.info("请打开设备.");
}
},
closeSocket() {
console.info("== in closeSocket")
try {
if(this.socket != null){
this.socket.close();
this.socket = null;
}
}
catch (ex) {
console.error(ex)
}
},
openReader() {
let host = "ws://127.0.0.1:6688";
let that = this
if(this.socket == null){
console.info("设备连接成功.");
this.socket = new WebSocket(host);
}else{
console.info("设备已打开.");
}
try {
this.socket.onopen = function (msg) {
};
this.socket.onerror = function(){
alert("请安装驱动.");
};
this.socket.onmessage = function (msg) {
console.info('=== lalala, msg: ');
console.info(msg)
console.info('in openReader(), this.sendFlag: ' + this.sendFlag)
if (typeof msg.data == "string") {
let msgM=msg.data+"";
if(that.sendFlag==1){
//console.info("清除头像成功.");
that.openReaderStart();
}else if(that.sendFlag==2){
if(msgM[0]=="1"){ //1:连接设备成功
console.info("连接成功.");
}else{ //2:连接设备失败
console.info("请连接设备.");
}
}else if(that.sendFlag==3 ){
console.info('that.sendFlag: ' + that.sendFlag)
console.info("== in this.sendFlag==3, scanning ID card...")
console.info('== msgM[0]: ' + msgM[0])
if(msgM[0] == "0"){
console.info("身份证阅读器异常,请联系管理员.");
}else if(msgM[0]=="3"){
console.info("请连接设备.");
}else if(msgM[0]=="4"){
console.info("请放身份证.");
}else if(msgM[0]=="5"){
console.info("读取身份证信息失败,请查身份证是否有效.");
}else if(msgM[0]=="6"){
console.info("读取身份证头像失败,请查身份证是否有效.");
}else{
//获得身份信息
// 应该是在这里修改，进行身份证的识别。
console.info('== msgM: ' + msgM)
that.customer_form.name = msgM.match(/name(\S*)name/)[1]
that.customer_form.id_card = msgM.match(/IDCode(\S*)IDCode/)[1]
that.customer_form.gender = msgM.match(/sex(\S*)sex/)[1]
that.customer_form.birthday = msgM.match(/birthDate(\S*)birthDate/)[1]
that.customer_form.address = msgM.match(/address(\S*)address/)[1]
console.info("== this.customer_form:")
}
}else if(that.sendFlag==4){
that.closeSocket();
if(msgM[0] == "1"){ //1:关闭设备成功
console.info("关闭设备成功.");
}
}
}
else{
alert("连接异常,请检查是否成功安装华旭J15S驱动.");
}
};
}
catch (ex) {
console.error(ex)
alert("连接异常,请检查是否成功安装华旭J15S驱动.");
}
},
}
