Hi Martin; It works thanks; but my condition needs "onkeydown" anyway now i am posting the complete solution for others
Code goal : user enters some char in textfield and press enter, and data comes via ajax. final TextField<String> txtMy= new TextField<String>("txtMy", new Model("")) ; txtMy.add(new AjaxFormComponentUpdatingBehavior("onkeydown") { @Override protected void onUpdate(AjaxRequestTarget target) { //... } @Override protected IAjaxCallDecorator getAjaxCallDecorator() { return new AjaxCallDecorator() { private static final long serialVersionUID = 1L; @Override public CharSequence decorateScript(CharSequence script) { return "if(wicketKeyCode(event) == 13){" + script + " return false;}"; } }; } ; }); Altug. 2010/10/19 Martin Grigorov <mgrigo...@apache.org> > 1. you need AjaxFormSubmitBehavior("onkeyup") > 2. you'll have to add AjaxCallDecorator to it do fire only when the key is > ENTER, i.e. event.keyCode === 13 > > 2010/10/19 Altuğ Bilgin Altıntaş <alt...@gmail.com> > > > Hi; > > > > How can i submit a form via Ajax when user hit the enter key on a > TextField > > ? > > > > I did below but it doesn't work. > > > > myTextField.add(new AjaxFormComponentUpdatingBehavior("onsubmit") { > > @Override > > protected void onUpdate(AjaxRequestTarget target) { > > //... > > > > } > > > > }); > > > > Thanks. > > >
