获取验证码，简单的一个判断正则
let phone = '13733537921'
//手机正则
let str = /^1(3|4|5|7|8)\d{9}$/;
if(phone.trim() != '' && str.test(phone)) {
//获取按钮点击后将按钮禁用并且倒计时
let t = 60;
let timer = setInterval(() => {
if (t == 0) {
clearInterval(timer);
this.msg = "重新获取";
this.disabled = false
} else {
this.disabled = true
t--;
this.msg = t + "S";
}
}, 1000);
console.log('手机号正确了')
}else{
//提示信息
console.log('手机号有误')
}
