How to access af:table rows in JavaScript

Question

Hi,
I have a requirement to access af:table rows in java script.I tried the same using following code.
getRows returns the correct no of rows from the table, but table.getValue() returns null.
var table = AdfPage.PAGE.findComponentByAbsoluteId('t1');
if (table != null){
alert(table.getRows());
alert(table.getFirst());
alert(table.getValue());
Any pointers on how i can achieve this.

We have a requirement where in,we have to check if the order number is already added to the cart(cart here is a table)
and this validation needs to be done as soon as you enter 10 digits in the input field for order number.
in short,order need to validated if its duplicate order against table at client side(sson as you enter 10 digits in order number)
initially I was trying to implemet this with ServerSide listner as below
Java script on page :
function addDuplicate(evt) {
var source = evt.getSource();
AdfCustomEvent.queue(source, "MyCustomServerEvent",
false);
event.cancel();
Bean method
public void callAddDuplicateSeverEvt(ClientEvent clientEvent) {
ADFContext.getCurrent().getPageFlowScope().put("dupOrderNumFlag", "N");
System.out.println("in handle Add duplicate::"+ ADFContext.getCurrent().getPageFlowScope().get("dupOrderNumFlag"));
input text on page
====
<af:inputText label="" id="it1" value="#{pageFlowScope.dspOrderNum}"
columns="14" autoComplete="off" styleClass="orderveritext"
maximumLength="10" >
<af:clientListener method="validateOrderNumChars" type="keyPress"/>
<af:clientListener method="enableAddButton" type="keyUp"/>
<af:clientListener method="addDuplicate" type=" keyPress "/>
<af:serverListener type="MyCustomServerEvent"
method="#{viewScope.HLKioskBean.callAddDuplicateSeverEvt}"/>
</af:inputText>
Problem with this solution is My application is KIOSK app(touch screen) on every key press in order num input field screen flickers,looks like its trying to do Full page rendering(though i do not have any PPR) in every call to serverListerner.
Please advise.
