Class UIButtonSpecJSActionToggle

public class UIButtonSpecJSActionToggle
extends UIButtonSpec

Standard toggle button that calls a JavaScript command for each change of state. A command can be a function or a piece of JavaScript code.

The toggle button has two states:

• When the button is deactivated: OFF
• When the button is activated: ON

When 'OFF', the user can click the button and it stays in the 'ON' state. When 'ON', the user can click the button and it stays in the 'OFF' state.

Two JavaScript actions are associated with this button:

• when the button is activated, the 'ON' confirmation message is displayed if it has been set (see UIButtonSpec.setConfirmationMessage(UserMessage)), then JSCmdOn is called
• when the button is deactivated, the 'OFF' confirmation message is displayed if it has been set (see setConfirmationMessageOff(UserMessage)), then JSCmdOff is called

The toggle button can be used in a <form> and acts like a checkbox. To enable this feature, the input name must be set. If the state of the button is 'ON', the name will be sent with the value ON_PARAMETER_VALUE, if the state of the button is 'OFF', nothing will be sent.

The state of the button can also be managed in JavaScript with the function UIJavaScriptWriter.addJS_setStateToToggleButton(String, String).

Since:

5.2.3
