          this.codeBtnText = "获取验证码";

        } else {
          this.disabled = true;

          time -= 1;
        }

    getCode() {
      this.$refs["bindForm"].validateField("newPhone", (err) => {
        if (err) {
          return;
        } else {
          this.validBtnText();
        }
      });

    handleOk(formName) {
      this.$refs[formName].validate(async (valid) => {
        if (valid) {
          this.visible = false;
          this.$emit("reset");
        }
      });
    },
  },
};
</script>

　　

（是的依旧没有接口）

其中包括了获取验证码的倒数功能，还是比较常用的。
