Hi,
It worked like a charm , thanks a lot. Just a couple of more things that i wanted to ask here:
1. On click of add I wanna refresh components of input and output only , not the entire page.
2. Want to add another button "Clear Result" that resets the output as well as the input.
Can you please help me with these two requirements as well?
Thanks a lot!!!!!
Hey dude sorry for the late reply. To set Input and Total to 0 you need to use reRender in VF page.
I am posting the modified code check this out.
<apex:page controller="Add">
<apex:form >
<apex:pageBlock title="Add N Numbers" >
<apex:pageBlockSection >
Input
<apex:inputText value="{!Input}" id="a"/>
Total
<apex:outputText value="{!Total}" id="tot"/>
<apex:commandButton value="Get Sum" action="{!add}" reRender="a,tot"/>
<apex:commandButton value="Clear Result" action="{!clear}" reRender="a,tot"/>
</apex:pageBlockSection>
</apex:pageBlock>
</apex:form>
</apex:page>
