Trying to get a program to wait for the return from a jquery request.

I have a program that needs to get some fresh data every time a button is pushed, then use that data to continue execution. I have read through a ton of suggestions bit none seem to work so i must be doing something wrong. This is the calling function:

function _onSpin(iNumBettingLines,iCoin,iCurBet) {
    if(iCurBet > s_aSession["iMoney"]){
        _dieError("INVALID BET: "+iCurBet+",money:"+s_aSession["iMoney"]);
        return;
    }
 makeNextResult(s_aSession["user_name"],s_aSession["coin_bet"],s_aSession["coin_bet"]);
	  responce_string = getNextResults();
    	_Result = [];
        var res_string = parseResult(response_string);
        var incomming = res_string.split("#");
        var this_ln;
        var x = 0;
        var bFreespin = 0;
        var bBonus = 0;
        var reel_pos;
        var bet_amt = 25;
        for(i=0;i<=incomming.length-1;i++){
       	   this_ln=incomming[i].split(",");
       	  _Result[i]=this_ln;
        }          
      }
      _initSettings();
      //$(s_oMain).trigger("bet_placed",{bet:iCoin,tot_bet:iCurBet});
      var rls;
      for(a=0;a<=_Result.length-1;a++){
      	if(_Result[0][0]==bet_amt){
      		rls = _Result[0][3];
      		break;
      	}
      }
  		if(rls!="undefined"){
       reel_pos =rls.split("*");
       for(a=0;a<reel_pos.length;a++){
          fs = reel_pos[a].split("%");
          _aFinalSymbols[a] = new Array(); 
          _aFinalSymbols[a][0] = fs[0];
          _aFinalSymbols[a][1] = fs[1];
          _aFinalSymbols[a][2] = fs[2];
          _aFinalSymbols[a][3] = fs[3];
          _aFinalSymbols[a][4] = fs[4];
  		 }
       
      }
       if(_Result[0][1]==0){
          var str = JSON.stringify(_aFinalSymbols);
          //_oInterface.refreshTotalBet();
          return "res=true&win=false&pattern="+JSON.stringify(_aFinalSymbols)+"&money="+s_aSession["iMoney"]+"&freespin="+s_aSession["iTotFreeSpin"]+"&bonus=false&bonus_prize=-1";
       }
   
      aRet = stuffResults(bet_amt);
      var str = JSON.stringify(_aFinalSymbols);
     // _oInterface.refreshTotalBet();
      return "res=true&win=true&pattern="+_aFinalSymbols+"&win_lines="+JSON.stringify(aRet)+"&money="+s_aSession["iMoney"]+
           "&tot_win="+iTotWin+"&freespin="+s_aSession["iTotFreeSpin"]+"&bonus="+s_aSession["bBonus"]+"&bonus_prize="+iPrizeReceived+"&cash="+s_aSession["iSlotCash"] ;
}

notice the line "responce_string = getNextResults();"

Here is the code for getNextResults()

function getNextResults(){
  foo(function(result) {
     return result;
  });
}

And finally the foo function

function foo(result) {
   var url = "http://server678.net/ExampleService.asmx";
    $.support.cors = true;
    $.ajax({
        type: "POST",
        url: url,
        contentType: "text/xml",
        dataType: "xml",
        data: _SoaMessage,
        processData: true, 
        success: function (data, status, req) {
           result(req.responseText);
        }
    });
}

The program calls getnextResult but instead of waining for the function to return a value it just blows right through it and response string is always undefined.

What I have tried:

I have been researching this for days and nothing seems to work. Please help.

Easiest way to do is, disable the button or create flag that says being processed. On return, success or failure, enable the button or clear the flag

You need to either add "async:false" to the ajax options to make the code wait for the results of your ajax call, or re-architect your code to make the code in the "success" event kick off whatever needs to be done with the data.

Easiest way to do is, disable the button or create flag that says being processed. On return, success or failure, enable the button or clear the flag.

JavaScript

$("#button_id").click(function(){
 if(this.enabled==false) {
   alert("still processing");
   return;
 }
 this.enabled=false;
 $.ajax(
  {
    url:...,
    success: function(result) {
     ... // Process result
    }, 
    error:function() { 
    },
    complete: function(){
      this.enabled=true
    }
  }
 )
  
})
