display confirmation box before deleting

[Suresh Khant]

Hi All,

I have jsf page which lists the users , and i have delete button (which deletes the user corresponding to it) , it is working fine , but i want to make confirmation before deleting the user

is there any way to implement that using javascript or richfaces component ....etc


here is the part of the code

	<rich:column>
						<f:facet name="header">
							<h:outputText value="#{msg.delete}" />
						</f:facet>
						
						<h:graphicImage value="/images/delete.gif"  />
						<a4j:commandLink reRender="usersPanel" 
							actionListener="#{usersBean.deleteUser}" value="#{msg.delete}" ></a4j:commandLink>
	</rich:column>

Yes there is. And although I am really beginning to hate JavaScript for any sort of serious work, this is one case where I recommend it.

On the commandButton:

onclick="if (! confirm('Really delete this?') ) { return false;}; return true; "

This works with plain JSF with no read for any extended capabilities so there's no need to use a4j. In fact, this works for basic HTML even without JSF.

If you code an onclick handler on a submit button (or equivalent), the submit will be cancelled if the event handler returns false.
