Onclick validation and action for a4j:commandbutton

Question

Hi, I have a requirement: when i click on a button, it has to show ok/cancel dialog box and if it is ok, then we have to call server code in ajax manner, else just be there doing nothing.
I implemented like below:
Case 1:
JSF code:
<a4j:commandbutton id="id1" value="Delete" onclick="showValidation()" action="#{bbean.deleteAction}" />.
JS code:
function showValidation()
if(confirm("Are you sure you want to delete?"))
return true;
else
return false;
It showed me the validation, but irrespective of Ok/Canel button that i clicked, the action's bbean.deleteAction gets executed.
I changed the JSF Code a little by providind return in the onclick as below,
Case 2:
<a4j:commandbutton id="id1" value="Delete" onclick="return showValidation()" action="#{bbean.deleteAction}" />.
This time, It showed me the validation, but irrespective of Ok/Canel button that i clicked, the action's bbean.deleteAction is NOT executed
I have tried several combinations, but no use. can anyone in the java world help me resolviing this issue? Thanks in advance and any small help in acheving my task is greatly appreciated.

Answer 1

On the initial 'Delete' button change action to be action="javascript:void();"
In your confirmation dialog have two buttons. Ok will invoke the original delete action, and cancel will simply close the confirmation dialog.
