Javascript 在IOS phonegap应用程序中清除数据库和本地存储

关于应用程序-

我正在ios phonegap应用程序中使用corodova 2.1.0

我的应用程序执行一些注册过程，它检查应用程序是否已注册，如果它在数据库或本地存储中找到数据，它会转到仪表板，否则它会要求注册。 在注册过程中，应用程序请求手机否如果后端的手机条目不可用，则应用程序将从数据库下载数据并将其存储在本地存储和数据库中

问题-

如果是首次注册，应用程序将下载数据并转到仪表板。如果我关闭应用程序，然后打开它，它将要求注册；如果我第二次注册，在进入仪表板后，如果我关闭应用程序，然后再次打开应用程序，它将显示dasboard afterwords，它不显示注册屏幕

我第一次查看了weinre，它也加载了数据库和本地存储中的所有数据

我只存储名称和用户id。但如果我在第一次安装后关闭应用程序，它将被清除。

 //Here is code which checks that user is registred or not

//这将在splashscrenn上发生

//$window.location.href = '#/SplashScreen';
function checkregistration(){

 var sqlU = 'SELECT ClubId, MemberId, MemberName FROM  member_master_dtls';
 var obj = {};
 var db = window.openDatabase("ROW_DB", "", "Cordova Demo", 200000);
 try{
    var  MID = localStorage.getItem('MyMemberID');
    console.log("MID befo "+ typeof(MID));

    console.log("MID === "+ (MID));
    if ( MID.length>0)
    {
     console.log("MID"+ MID);
     RowDbService.CheckVersion();
     $window.location.href = '#/Dashboard';
    }else{
   db.transaction(function(tx) {
     //console.log('in db trans');
     tx.executeSql(sqlU, [], SuccessChkMemlst_local, errorCB);
     });
   }
    }
   catch(err){
  db.transaction(function(tx) {
 //console.log('in db trans');
   tx.executeSql(sqlU, [], SuccessChkMemlst_local, errorCB);
    });
 }
}

function SuccessChkMemlst_local(tx, results) {
 //alert("success splash");
 //console.log("successlist = " + results.rows.length);
 if (results.rows.length == 0) {
  //localStorage.setItem('globalx', '1');
  globalx = 1;
  $window.location.href = '#/Register';
  //console.log(results);
 } else {                
  RowDbService.CheckVersion();
  $window.location.href = '#/Dashboard';
 }
}

所以，这种情况正在发生。伟大的现在，当我们看不到您的代码时，您希望我们做什么？我也只在本地存储中存储数据，它在我杀死应用程序后也会被清除（我没有在数据库中存储任何数据）
