With the inclusion of the optional 15 * <a href="module_menu.html">Menu Control</a>, the Button Control can also be 16 * used to create menu buttons and split buttons, controls that are not 17 * available natively in HTML. The Button Control can also be thought of as a 18 * way to create more visually engaging implementations of the browser's 19 * default radio-button and check-box controls.</p> 20 * <p>The Button Control supports the following types:</p> 21 * <dl> 22 * <dt>push</dt> 23 * <dd>Basic push button that can execute a user-specified command when 24 * pressed.</dd> 25 * <dt>link</dt> 26 * <dd>Navigates to a specified url when pressed.</dd> 27 * <dt>submit</dt> 28 * <dd>Submits the parent form when pressed.</dd> 29 * <dt>reset</dt> 30 * <dd>Resets the parent form when pressed.</dd> 31 * <dt>checkbox</dt> 32 * <dd>Maintains a "checked" state that can be toggled on and off.</dd> 33 * <dt>radio</dt> 34 * <dd>Maintains a "checked" state that can be toggled on and off. Use with 35 * the ButtonGroup class to create a set of controls that are mutually 36 * exclusive; checking one button in the set will uncheck all others in 37 * the group.</dd> 38 * <dt>menu</dt> 39 * <dd>When pressed will show/hide a menu.</dd> 40 * <dt>split</dt> 41 * <dd>Can execute a user-specified command or display a menu when pressed.</dd> 42 * </dl> 43 * @title Button 44 * @namespace YAHOO.widget 45 * @requires yahoo, dom, element, event 46 * @optional container, menu 47 */ 48 49 50 (function () { 51 52 53 /** 54 * The Button class creates a rich, graphical button. 55 * @param {String} p_oElement String specifying the id attribute of the 56 * <code><input></code>, <code><button></code>, 57 * <code><a></code>, or <code><span></code> element to 58 * be used to create the button. 59 * @param {<a href="http://www.w3.org/TR/2000/WD-DOM-Level-1-20000929/level- 60 * one-html.html#ID-6043025">HTMLInputElement</a>|<a href="http://www.w3.org 61 * /TR/2000/WD-DOM-Level-1-20000929/level-one-html.html#ID-34812697"> 62 * HTMLButtonElement</a>|<a href=" 63 * http://www.w3.org/TR/2000/WD-DOM-Level-1-20000929/level-one-html.html# 64 * ID-33759296">HTMLElement</a>} p_oElement Object reference for the 65 * <code><input></code>, <code><button></code>, 66 * <code><a></code>, or <code><span></code> element to be 67 * used to create the button. 68 * @param {Object} p_oElement Object literal specifying a set of 69 * configuration attributes used to create the button. 70 * @param {Object} p_oAttributes Optional.
