function parameter

[ryanvnd]

I'm Looking for an example for function parameter, similar to as in properties of alerts with a alert tab and customized popup message box to select options like page name and time of alert etc

Alert routine

Is this the sort of routine you are looking for?

AlertExamp_1.efs

//Basic List and/or Sound alert function
//provided by red49er                   

var aFPArray = new Array();
var x = 0;

    aFPArray[x] = new FunctionParameter("nAlerts", FunctionParameter.STRING);
    with(aFPArray[x++]){
        setName( "Select the alerts you want" );
        addOption("list"); 
        addOption("sound");
        addOption("list & sound");
        addOption("none");
        setDefault("list & sound"); 
    }

function preMain(){
    //only calc on each new bar, else alert will sound on every tick
    setComputeOnClose();
}

var bInit = false;
var aInit = false;      //alert function initiate flag
var alerts = null;      //holds list/sound user selection
var listAlertFlag = false;
var soundAlertFlag = false;
var trigger = true;     //alter this to trigger LONG or SHORT alerts whilst testing

function main(nAlerts){
    if (bInit == false) {
        //set up alerts and sounds
        alerts = nAlerts;
        Alert_Actions(alerts);
        bInit = true;
    }

//do your indicator calculations
//and trigger Alert if conditions met
    if(trigger == true){
        var tmp = "LONG ALERT AT "+formatPriceNumber(close(0));
        Alert_Actions(tmp);
    }
    if(trigger == false){
        var tmp = "SHORT ALERT AT "+formatPriceNumber(close(0));
        Alert_Actions(tmp);
    }
return close(0);    //your indicator
}
//== Alert_Actions function ----------------------------------------
function Alert_Actions(tem){
var tmp = tem;
    //scan user selection and initiate Flags
    if(!aInit){
        if(tmp.indexOf("list")!= -1){
            listAlertFlag = true;
        }

        }
        aInit = true;
        return;
    }
    if(soundAlertFlag){
        Alert.playSound("Ding.wav"); //select sound of your choice
    }                                //C:\Program Files\eSignal\Sounds
    if(listAlertFlag){
        nHour = getHour();
        nMins = getMinute();
        time = nHour+":"+nMins;
        if(tmp.indexOf("LONG")!= -1){       //Long breakout
            Alert.addToList(getSymbol()+"  "+getInterval(),tmp+" : "+time,Color.black,Color.green);
        }
