aps/RadioButton

Creates an HTML radio-button.

Compatibility

All user panels - CP and UX1

Overview

The RadioButton widget is a modified analog of the radioButton HTML element.

In addition to the standard properties of the HTML element, such as value, checked, and disabled. the widget may have description (description), a name for displaying in a FieldSet (label or title), and may also have child elements. As with a usual HTML element, grouping of several RadioButton widgets is implemented by specifying the same value for their name property. For more information about the name property see Base Properties and Methods.

Note

In the next versions, we will implement a special widget for the aps/RadioButton group. If you already use the aps/RadioButton group, you can monitor user activity by means of the onClick method.

var val;
load(["aps/FieldSet", [
   ["aps/Panel", [
      ["aps/RadioButton", {
         name: 'test',
         onClick: function(){ val = 1; }
      }],
      ["aps/RadioButton", {
         name: 'test',
         onClick: function(){ val = 2; }
      }],
      ["aps/RadioButton", {
         name: 'test',
         onClick: function(){ val = 3; }
      }]
]]]]);

Find the nested rules for this widget in the recommended Widget Hierarchy.

The widget may also have child widgets from the input category.

Examples

The Declarations section describes generally the methods of widget declaration.

Declaration using Loader

RUN DEMO

require(["aps/load", "aps/ready!"],
  function(load){
    "use strict";

    load(["aps/PageContainer", [
        ["aps/Panel", [
            ["aps/RadioButton", {
                value: "loader",
                description: "I am RadioButton"
            }]
    ]]]]);
});

Declaration using Constructor

RUN DEMO

require(["aps/RadioButton", "aps/Panel", "aps/PageContainer", "aps/ready!"],
  function(RadioButton, Panel, PageContainer){
    "use strict";

    var page = new PageContainer({}, "simpleRadioButton");
    var panel = new Panel();
    panel.addChild(new RadioButton({
      value: "program",
      description: "I am RadioButton"
    }));
    page.addChild(panel);
    page.startup();
});

Radio Button as a Parent

aps/_input
function

Focusing on the focusNode of the current object

any

Get a property of the Stateful instance

getChildren ()

array

Returns all direct children of this widget, i

getParents ()

array

Discover and return all parents of the widget

placeAt ()

dijit/_widgetbase
function

Place this widget somewhere in the DOM based on standard dojo/dom-construct::place() conventions

removeAll ()

undefined

Remove all children in the widget

removeChild (widget)

undefined

Removes the passed widget instance from this widget and destroys it

reset ()

undefined

Resets the widget

set ()

object
function

Set a property of the Stateful instance

startup ()

undefined

Gets started after the DOM fragment is added to the document

validate ()

boolean

Called by oninit, onblur, and onkeypress

addChild

Makes the given widget a child of this widget. Inserts specified child widget’s dom node as a child of this widget’s container node, and possibly does other processing (such as layout).

Return: undefined

ARGUMENT

TYPE

DESCRIPTION

child

Widget

Child widget

insertIndex

Number
String

Position child in the parent widget

cancel

Sets the isBusy property to false.

Return: object

destroy

Destroy this widget. Will also destroy any resources (including widgets) registered via this.own(). This method will also destroy internal widgets such as those created from a template.

Return: undefined

focus

Focusing on the focusNode of the current object.

Return: aps/_input function

get

Get a property of the Stateful instance. Get a named property of the Stateful object. The property may potentially be retrieved via a getter method in subclasses.

In the base class, this just retrieves the object’s property.

Return: any

getChildren

Returns all direct children of this widget, i.e. all widgets underneath this.containerNode whose parent is this widget. Note that it returns not all descendetns, but only the direct children. Analogous to Node.childNodes, except containing widgets rather than DOMNodes.

The result intentionally excludes internally created widgets (a.k.a. supporting widgets) outside of this.containerNode.

Note the returned array is a simple array. The application code should not assume existence of methods like forEach().

Return: array

getParents

Discover and return all parents of the widget.

Return: array

placeAt

Place this widget somewhere in the DOM based on standard dojo/dom-construct::place() conventions. A convenience function providing a simple shorthand mechanism to put an existing (or newly created) widget somewhere in the DOM, and allow chaining.

Return: dijit/_widgetbase function

removeAll

Remove all children in the widget.

Return: undefined

removeChild

Removes the passed widget instance from this widget and destroys it. You can also pass in an integer indicating the index within the container to remove (ie, removeChild(5) removes the sixth widget).

Return: undefined

ARGUMENT

TYPE

DESCRIPTION

widget

Widget
Int

Child widget or index

reset

Resets the widget.

Return: undefined

set

Set a property of the Stateful instance. Sets named properties of the stateful object and notifies the watchers of the property. A programmatic setter may be defined in subclasses.

Return: object function

startup

Gets started after the DOM fragment is added to the document Called after the widget and its children have been created and added to the page, and all related widgets have finished their create() cycle, up through postCreate().

Note that startup() may be called while the widget is still hidden, for example if the widget is inside a hidden dijit/Dialog or an unselected tab of a dijit/layout/TabContainer. For widgets that need to do layout, it’s best to put that layout code inside resize(), and then extend dijit/layout/_LayoutWidget so that resize() is called when the widget is visible.

Return: undefined

validate

Called by oninit, onblur, and onkeypress. Show missing or invalid messages if appropriate, and highlight textbox field.

Return: boolean

Public Events
