IT:AD:Promise:HowTo:Invoke Async Success and Failure Handlers

THe following uses defined success/failure methods and implicitly passing args. Makes for cleaner looking code.

$(function(){
    DemoC();
});


function DemoC(){
    SimulationUsingPromises(5).then(DoSuccess, DoFail);
}


function SimulationUsingPromises(data){
    //setup a deferred object:
    var deferred = $.Deferred();
    
    // Take a second, then invoke a callback:
    window.setTimeout(
        function() {
            if (Math.round(Math.random())==1){
                //invoke resolve, passing results:
                deferred.resolve(data+1);
            }else{
                //invoke reject, passing results:
                deferred.reject(data-1);
            }
        },1000);
    //important: pass back the promise handle:
    return deferred.promise();
}

//The defined callback method:
function DoSuccess(data){$("#r").html("Success: "+data);}

//The defined callback method:
function DoFail(data){$("#r").html("Fail: "+data);}
