Question

This seems like such a simple question.

I have several Edit boxes on my xPage. The user may or may not enter an integer value. The fields are set to accept an integer.

I want to to total all of the values in those fields. I have the following, that works, but it seems awfully inefficient. Is there an easier way to do this?

var DeliveryTotal:int = getComponent(ctlName).getValue() == null    ? 0 : parseInt(getComponent(ctlName).getValue());
var Delivery100s:int = parseInt(getComponent("inputTextDelivery100s").getValue());
var Delivery50s:int =  parseInt(getComponent("inputTextDelivery50s").getValue());   
var Delivery20s:int =  parseInt(getComponent("inputTextDelivery20s").getValue());
var Delivery10s:int = parseInt(getComponent("inputTextDelivery10s").getValue());
var Delivery5s:int = parseInt(getComponent("inputTextDelivery5s").getValue());
var Delivery1s:int = parseInt(getComponent("inputTextDelivery1s").getValue());  


DeliveryTotal = isNaN(DeliveryTotal) ? 0 : DeliveryTotal;
Delivery100s = isNaN(Delivery100s) ? 0 : Delivery100s;
Delivery50s = isNaN(Delivery50s) ? 0 : Delivery50s;
Delivery20s = isNaN(Delivery20s) ? 0 : Delivery20s;
Delivery10s = isNaN(Delivery10s) ? 0 : Delivery10s;
Delivery5s = isNan(Delivery5s) ? 0 : Delivery5s;
Delivery1s = isNan(Delivery1s) ? 0 : Delivery1s;

var totalEntered = Number(Delivery100s) + Number(Delivery50s) + Number(Delivery20s);

Answer 1

Can you compute the values client side? If so then you could use the following jQuery. It selects all the fields with id starting with inputTextDelivery and adds the value together.

Number(0 +..) will convert blanks to 0 and 0123 will be converted to 123

var sum=0;
$('[id^=inputTextDelivery]').each(function() {
    sum += Number(0+$(this).val());
});

If not you can certainly remove the block of code checking for 0 by

var totalEntered = Number(0+Delivery100s) + Number(0+Delivery50s) + Number(0+Delivery20s);
