在ionic中使用短信验证码倒计时

页面上

<button class="code" (click)="getCode()" [disabled]="!verifyCode.disable">{{verifyCode.verifyCodeTips}}</button>
//getCode()为点击按钮运行的方法

ts中

//验证码倒计时 全局定义变量
  verifyCode: any ={
          verifyCodeTips: "获取验证码",
          countdown: 60,//总共时间
          disable: true
      };

//获取验证码的方法
getCode(){
       //每次点击时初始化
      this.verifyCode = {
          verifyCodeTips: "获取验证码",
          countdown: 60,//总共时间
          disable: true //禁止按钮被点击
      }
      this.settime()
  }

//倒计时
  settime() {
    if(this.verifyCode.countdown == 0) {
        this.verifyCode.verifyCodeTips = "获取验证码";
        this.verifyCode.disable = true;
        return;
    } else {
        this.verifyCode.countdown--;
    }
    setTimeout(() => {
        this.verifyCode.verifyCodeTips = "重新获取" + this.verifyCode.countdown + "秒";
        this.settime();
    }, 1000);
  }
