Command.type property

  • 發行項

Gets or sets the type of the command.

Syntax

<element 
  data-win-control="WinJS.UI.Command"
  data-win-options="{type: value}">
</element>

var type = command.type;
command.type = type;

Property value

Type: String**

The command can be one of the following types:

  • "button"

    This is the default value for the type. It defines a standard button and can only be applied to a <button> element.

  • "toggle"

    This creates a button that can be selected or de-selected. When the button is selected, the colors of the icon of the Command are reversed (black to white and white to black, for example). Only a <button> element can host a toggle Command.

  • "flyout"

    This creates a button that reveals an HTML fragment adjacent to it (a flyout). To create a flyout Command, you need to specify both the type as "flyout" and set its flyout property. The flyout property must reference a defined Flyout control. Only a <button> element can host a flyout Command.

  • "separator"

    This creates a horizontal line in the app bar or toolbar, to create a visual separation between other Command controls. Only a <hr/> element can host a separator Command.

  • "content"

    This creates an Command that can host other HTML markup inside of it, including text, <input> tags, and even a subset of WinJS controls. Only a <div> element can host a content Command.

Remarks

For a toggle command to work with accessibility tools like Narrator, you must attach an onPropertyChange event handler by using the attachEvent method. You must use the detachEvent method to remove the event handler.
