How to disable the enter key for a p:commandButton?

问题

I have a p:commandButton that actually is the logout button. It is placed in the north p:layoutUnit and if I press the enter key in any form it always log me out. I dont want that button to respond the enter key. How to do that?

回答1:

Put a hidden button with no action in the logout form and capture the enter key via p:defaultCommand.

<p:defaultCommand target="dummy"/>
<p:commandButton id="dummy" process="@none" global="false" style="display:none;"/> 

回答2:

Nest the button within this form tag:

<h:form id="thisform" onkeypress="if( event.keyCode == 13){event.keyCode=0;}">
