Key Enter on Form Does not work on IE8

2012-01-30 Thread Krishna Mohan 
I have a form and few panels in it.

In panel 'A' i have search button , panle 'A' consist of set of other panels 
'B'.
panel 'B' has few fields for example field 'F' 

Each panel is implemented in sepearate java class

I have requirement wherein after entering text in the field 'F' on press of 
Enter 
button search should be performed with out click of search button.

To achieve this i tried following snippet

 add(new AjaxEventBehavior(onkeypress)
  {
@Override protected CharSequence getCallbackScript(boolean 
onlyTargetActivePage)
{
  return generateCallbackScript(wicketAjaxGet(' + 
getCallbackUrl(onlyTargetActivePage) +  + KEYPRESS_PARAM + 
='+wicketKeyCode(event));
}

@Override protected void onEvent(AjaxRequestTarget target)
{
  String paramValue = 
RequestCycle.get().getRequest().getParameter(KEYPRESS_PARAM);
  int key = Integer.parseInt(paramValue);
if (key == 13)
{
   submitSearchForm();
 }
}

});
but using above the text in the field is cleared and get wrong search. but when 
i remove focus from the field and press Enter i get desired result.

My question here is how to perform search, remaining in the field(with focus in 
the field)

or their any other approach to get my requirement 

i also tried

  @Override protected void onInitialize()
  {
super.onInitialize();
PnWebForm form = findParent(PnWebForm.class);
if (form != null)
{
  form.setDefaultButton(this.pnWebSearchButton);
}
  }

Even this did not work and the problem is only with IE8 or its earlier 
versions, 
it works with Mozilla firefox,chrome,safari etc

Krishna

 I'm not sure what Igor meant with this suggestion.
 
 I think .setDefaultButton() should do what you need.
 
 Here is another suggestion from me:
 
 Add a non-Ajax behavior to the text field which adds 'keyup' event
 handler. When the user types something in the field then check the
 keyCode from the event and if it is 13 then call
 'document.getElementById(submitButtonId).click()'.

I describe my problem agin

I have a form and few panels in it.

In panel 'A' i have search button , panle 'A' consist of set of other panels

i also tried Igor's idea
