Flex (as3) add parameters to addEventListener
Posted on 2013-05-11
Hello, I am using this code, can't really also release the asp script(license) that this code requires for the database connections but you get the idea:
The problem is that the mssqlQuery is called from a 'for each' statement that reads from facebook API(gets facebook id's from all of your friends), then if the FID(their facebook ID) is in my database it will mark them on a map(FriendsPopMap), the problem is that since the mssqlQuery takes more time I can't store the current other userinfo(that comes from facebook) in currentuserhandling as the facebook runs faster then the mssqlQuery, I wan't to maybe add parameters to the mssqlQuery and also the mssqlResult so it can get the extra data from facebook, that is not stored in my database(script above only connects to my database).
mssqlQuery("SELECT * FROM Test_Locations WHERE FID = '"+ MFID +"'","GetFriendInfo");
public function mssqlQuery(sql:String,fid:String):void {
var http:HTTPService = new HTTPService;
var parm:Object = new Object;
parm.fas_sql = sql;
parm.fas_db = mssql_db;
http.url = mssql_url+"?irand="+Math.random();
http.showBusyCursor = true;
http.request = sql;
http.addEventListener(ResultEvent.RESULT, mssqlResult);
http.addEventListener(FaultEvent.FAULT, mssqlFault);
http.method = "POST";
sqlToken = http.send(parm);
sqlToken.param = fid;
}
private function mssqlFault(event:FaultEvent):void {
var err:String = event.fault.faultString;
trace(err);
}
/********************************************************
* mssqlResult() should be used to handle all of the
* returns of your queries. This will end up being a
* long case list.
*
*********************************************************/
private function mssqlResult(event:ResultEvent):void{
//Note: All Results are stored in the
// event.result object
//Create a new case/break for each of your
//sql query statements
var directionList:ArrayCollection;
var countdrac:int = 0;
switch(event.token.param){
case "GetFriendInfo":
if (event.result && event.result.results && event.result.results.record && (event.result.results.record.length > 0)){
FriendsPopMap(currentuserhandling.name, "http://graph.facebook.com/"+currentuserhandling.id+"/picture", event.result.results.record.Place, event.result.results.record.Personal, event.result.results.record.CurrentUpdateInterval)
currentuserhandling = null;
trace("ran");
}
break;
case "SetMyInfo":
//just sends data out no response needed
break;
}
}
The problem is that the mssqlQuery is called from a 'for each' statement that reads from facebook API(gets facebook id's from all of your friends), then if the FID(their facebook ID) is in my database it will mark them on a map(FriendsPopMap), the problem is that since the mssqlQuery takes more time I can't store the current other userinfo(that comes from facebook) in currentuserhandling as the facebook runs faster then the mssqlQuery, I wan't to maybe add parameters to the mssqlQuery and also the mssqlResult so it can get the extra data from facebook, that is not stored in my database(script above only connects to my database).

But for anserwing on your question describing in the titile: "Flex (as3) add parameters to addEventListener"
You can use my function:
now you can change addEventListener call
And your "mssqlResult" event handler function will able two receive to parameters
private function mssqlResult(event:ResultEv
for(var name:String in param)
trace(name + "="+ param[name]);
}
You can use my function:
public static function FunctionParaUtil(callBack:Function, ...args:Array):Function{
var handler:Function;
handler = function(event:Event):void{
var func:Function = arguments.callee.prototype.func;
var args:Array = arguments.callee.prototype.args;
func.apply(null, [event].concat(args));
};
handler.prototype.func = callBack;
handler.prototype.args = args;
return handler;
}
now you can change addEventListener call
var parm:Object = new Object;
parm.fas_sql = sql;
parm.fas_db = mssql_db;
http.url = mssql_url+"?irand="+Math.random();
http.showBusyCursor = true;
http.request = sql;
http.addEventListener(ResultEvent.RESULT, FunctionParaUtil(mssqlResult, parm));
And your "mssqlResult" event handler function will able two receive to parameters
private function mssqlResult(event:ResultEv
for(var name:String in param)
trace(name + "="+ param[name]);
}

I know the transition can be hard. We got used to the ease of use ActionScript 2 had, but honestly, it became problematic later on, especially if designers were involved in the project and found it easy to add code as they saw fit.
