      console.log(this.data.phone, '手机号')
      var _this = this;
      var myreg = /^(14[0-9]|13[0-9]|15[0-9]|16[0-9]|17[0-9]|18[0-9]|19[0-9])\d{8}$$/;
      if (this.data.phone == "") {

        http.sendsms({
          data: {
            phone: this.data.phone
          },
          success(res) {

              //  iscode: res.data.data
            })
            var num = 60;
            var timer = setInterval(function () {
              num--;
              if (num <= 0) {
                clearInterval(timer);
                _this.setData({
