*** Version 2.2.1 *** Added the following features: ----------------------------- + Added "getHiddenField" method to YAHOO.widget.Button. Fixed the following bugs: ------------------------- + Removed built-in use of the Event utility's "onAvailable" method from the constructor of Button and ButtonGroup as it was preventing the addition of event listeners on instances created from existing markup. Going forward Button and ButtonGroup instances created from existing markup can only be instantiated once their source HTML element is available in the DOM. The Button examples illustrate how this can be accomplished. + Modified code so that disabled Button instances no longer fire DOM events. + Pressing the enter key while focused on a form field whose parent form contains a Button instance of type "submit" will now automatically submit the form using the first Button instance of type "submit". + Clicking a Button instance of type="submit" will now cause the Button's parent form's "submit" event to fire. + Modified Button CSS so that the filter used to apply alpha transparency to a Button's background PNG is only used by IE 6. The previous code was enabling IE's Alpha image loader for IE 7 in Quirks mode. + Fixed documentation error for "getForm" method. Changes: -------- + Made the "submitForm" method of YAHOO.widget.Button public (was previously protected). + Removed "init" event and corresponding "oninit" configuration attribute from YAHOO.widget.Button and YAHOO.widget.ButtonGroup. + Added the CSS class "ie6" to button.css. This classname is append to root DOM element of Button instances created with IE 6. By default this class is used to apply a filter that gives alpha transparency to a Button's background PNG. *** Version 2.2.0 *** * Button Control introduced
