注册时，验证码第一次老是为空 等待60秒再次获取验证码就没问题了求帮助。。。

这是我注册页面的代码
var mobile = document.getElementById("mobile").value;
var verify_code = document.getElementById("verify").value;
// var invite = document.getElementById("invite").value;
var password = document.getElementById("password").value;

            if(mobile == "")  
            {  
                mui.toast("请输入手机号！");  
                return false;  
            }  
            if(verify_code == "")  
            {  
                mui.toast("请输入验证码！");  
                return false;  
            }  
            if(password == "")  
            {  
                mui.toast("请输入密码！");  
                return false;  
            }  

            var _mobile_token = common.getUserInfo('_mobile_token');  
            var data = {mobile:mobile, password:password, code:verify_code, _mobile_token:_mobile_token};  
            common.request('/console/register', data, 'post',function(data){  
                if(data.status == 1)  
                {  
                    mui.alert(data.info,function(){  
                        mui.back();  
                    })  
                }  
                else  
                {  
                    mui.toast(data.info);  
                }  
            });  
        });  

        var sendCodeBtn = document.getElementById("send-code");  
        sendCodeBtn.addEventListener("tap",function(){  
            var mobile = document.getElementById("mobile").value;  
            if ( mobile == '' ) {  
                mui.toast("请输入手机号！");  
                return false;  
            }  

            common.request_callback_success = function(data){  
                common.setUserInfo('_mobile_token', data.info['_mobile_token']);  
                mui.toast('短信验证码已下发至您的手机，请注意查收');  
                time(sendCodeBtn);  
                common.request_func_reset();//回调函数复位  

            }  
            common.request('/sms/send', {type:'register', 'mobile':mobile}, 'post');  
        });  

这是我js代码
/**

  owner.request_func_reset = function(func) {

  if (typeof func == 'undefined'|| func == '' ) {  
      func = 'ALL';

      owner.request_callback_success = function(data) {  
          if (typeof data.info == 'string') {  
              mui.alert(data.info);  
          } else {  
              mui.alert('处理成功！');  
          }  
      }  
  
      owner.request_callback_fail = function(data) {  
          mui.toast(data.info);  
      }  
  } else if (func == 'fail') {  
      owner.request_callback_fail = function(data) {

      }  
  } else {

          } else {  
              mui.alert('处理成功！');  
          }  
      }  
  }  
  
  owner.request_callback = function(data) {  
      if (data.status == 0) {  
          owner.request_callback_fail(data)  
      } else {

  }

  owner.log = function(data) {
  console.log(JSON.stringify(data));
  }

求助 帮忙 谢谢~~~~图片是我第一次注册的效果 再次获取验证码后就能注册成功。。
