Doing an action on press of key in a form
I have a form, few panels in it.
In one of the panel i have few fields and in other panel a search button.
I have requirement wherein after entering text in the field 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
Form form = findParent(Form.class);
if (form != null)
{
form.setDefaultButton(searchButton);
}
but form is always null for me
Regards
Krishna

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
'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
Form form = findParent(Form.class);
if (form != null)
{
form.setDefaultButton(searchButton);
}
but form is always null for me
i also tried Igor's idea
i get below error on using AjaxFormComponentUpdatingBehavior
WicketMessage: Behavior
nl.planon.hera.filters.quicksearch.PnWebAdvancedSearchPanel$3 can only be added
to an instance of a FormComponentRoot
cause:org.apache.wicket.WicketRuntimeException: Behavior
nl.planon.hera.filters.quicksearch.PnWebAdvancedSearchPanel$3 can only be added
to an instance of a FormComponent

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()'.

AjaxFormComponentUpdatingBehavior must be used on a FormComponent (sub)class.
