Cordova – How to wait until the callback function returns?

function directPath(src, dest)
{
 var db = window.openDatabase("Database", "1.0", "PhoneGap Demo", 200000);
 db. transaction(queryDB, errorCB);
 return arrayroute;
}

function queryDB(tx)
{
 tx.executeSql(query, [], querySuccess, errorCB);
}

function querySuccess(tx,results) {
 //Write some code here.
}

 function errorCB(err) {
 alert("Error in SQL: "+ err);
}

I am using phonegap to make an Android application. I am using phonegap’s Storage api to query the database. This is my code:

function directPath(src, dest)
{
 var db = window.openDatabase("Database", "1.0", "PhoneGap Demo" , 200000 );
 db.transaction(queryDB, errorCB);
 return arrayroute;
}

function queryDB(tx)
{
 tx .executeSql(query, [], querySuccess, errorCB);
}

function querySuccess(tx,results) {
 //Write some code here.
} 

function errorCB(err) {
 alert("Error in SQL: "+ err);
}

The problem is that I want to wait until the callback method querySuccess Finish execution before returning from the directPath method.

Don’t try to fight against asynchrony: your application may eventually appear to be unresponsive to the user. For any code that must be executed later , Please use querySuccess callback.
