Hello Guys, i have a small problem. i have this form where i calculated updated balance based on data already available and data from 2 text inputs. the result is correct but i would like that when someone types in one textinput the balance is computed and then further if someone inputs a figure in the second text input. below is the code i got as of now. It needs improvement.


<?xml version="1.0" encoding="utf-8"?>

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"

layout="vertical"

horizontalAlign="center"

verticalAlign="top">

<mx:Script>

<![CDATA[

private function calBalance(event:Event):void

{

var amt:Number=new Number;

if (Number(amountPaid.text) > Number(currentPaid.text) && Number(manFees.text) > Number(currentFees.text)){

amt = Number(currentBal.text) - ((Number(amountPaid.text) - Number(currentPaid.text)) + (Number(manFees.text) - Number(currentFees.text)))

}

balance.text=amt.toFixed(0);

}

]]>

</mx:Script>

<mx:Panel height="400"

 layout="vertical">


<mx:HBox>

<mx:Label text="Payment:"

 width="113"/>

<mx:TextInput id="amountPaid" change="calBalance(event)"/>

<mx:Label text="Management Fees:"/>

<mx:TextInput id="manFees" change="calBalance(event)"/>

</mx:HBox>


<mx:HRule width="100%"/>

<mx:HBox>

<mx:Label text="Current Balance:"

 width="126"/>

<mx:Text text="515000"

id="currentBal"/>

</mx:HBox>

<mx:HBox>

<mx:Label text="Amount Already Paid:"

 width="126"/>

<mx:Text text="500000"

id="currentPaid"/>

</mx:HBox>

<mx:HBox>

<mx:Label text="Fees Paid:"

<mx:Text text="0"

id="currentFees"/>

</mx:HBox>

<mx:HBox>

<mx:Label text="updated Balance:"

<mx:Text id="balance"/>

</mx:HBox>

Actually this is the entire code with 2 scenarios. but needs a liltle tweaking to make it better. by better i mean, the balance starts off getting computed the moment either the amountPaid textinput or manFees textinput is being fed in a figure. thanks

I'm not sure if you are aware, but using a form is a better choice. To answer your question, use a change listener on the text input to achieve what you need.

Hello, thanks for the response. i am already using a change listener on the text input but when i start typing in the first textinput, i don't get the desired result. its only when i type in both that the evnet kicks in.

It could be that unless both text inputs contain strings that parse into numbers you’ll get funky results like NaN for empty string.
