I have an <html:image> tag with onClick set. So when users press button, it
does something. The problem is what if user type input into a field say
keywordSearch, then they press <ENTER>. In that case the logic in the
onClick attribute is not executed. I tried to put that into an onSubmit
tag, but there's no such attibute. So how can I get it so that if a user
press <ENTER> instead of clicking the button, that I can execute some custom
logic (to set form param) before it goes to my Action class? Thanks.
