请教一个正则的写法！

Question

有如下JSON字符串内容：

{"__type":3003,"__id":"1","channel":"B3","msg":" SPEED,r/min,1017,1,0;TORQUE,Nm,1012.0,1,0;功率,kW,1008.0,1,0;备用温度2,℃,1014.0,1,0;备用温度3,℃,1019.0,1,0;备用温度4,℃,1020.0,1,0;备用温度5,℃,1024.0,1,0;备用温度6,℃,1022.0,1,0;备用温度7,℃,1023.0,1,0;备用温度8,℃,1022.0,1,0;备用温度9,℃,1021.0,1,0;备用温度10,℃,1026.0,1,0;备用温度11,℃,1029.0,1,0","from":null}

可以看到在msg属性的头尾各有一个特殊的十六进制字符，分别是#2，#3的十六进制形式，正则应如何判断在这样一个JSON之中的msg属性头尾是否存在这两个特殊字符呢？

Answer 1

dataObj = {"__type":3003,"__id":"1","channel":"B3","msg":" SPEED,r/min,1017,1,0;TORQUE,Nm,1012.0,1,0;功率,kW,1008.0,1,0;备用温度2,℃,1014.0,1,0;备用温度3,℃,1019.0,1,0;备用温度4,℃,1020.0,1,0;备用温度5,℃,1024.0,1,0;备用温度6,℃,1022.0,1,0;备用温度7,℃,1023.0,1,0;备用温度8,℃,1022.0,1,0;备用温度9,℃,1021.0,1,0;备用温度10,℃,1026.0,1,0;备用温度11,℃,1029.0,1,0","from":null}
//你是要同时存在，还是存在任意一个？同时存在如下，如果存在任意一个则为  re=/^\u{0002}|\u{0003}$/u
re=/^\u{0002}.*\u{0003}$/u
if ( re.test(dataObj.msg) ) {
    console.log("匹配到")
}else{
    console.log("没匹配到")
}
