The <command> tag defines a command button, like a radiobutton, a checkbox, or a button.

The command element is only visible if it is inside a menu element. If not, it will not be displayed, but can be used to specify a keyboard shortcut.

The command element is meant to encapsulate something that you can do.It provides an abstraction layer between UI and commands, so that you can make multiple UI elements refer to the same command.

<command > is a new tag added in HTML5 but still not supported in most browsers. It is used to represent a command that the user can invoke. It is almost an obsolete element that may be deprecated in the coming few years.

the <command> element is meant to be an abstraction to let us refer to the same "command" from multiple menu entries or buttons.

the <command> can be part of a context menu or toolbar, using the menu element, or can be put anywhere else in the page, to define a keyboard shortcut.

The type attribute is currently not supported in any of the major browsers. The <command> element has now been dropped from the HTML5 specification. Therefore, you should not use it in your HTML markup.

 

There are3 kinds of attributes that you can add to your HTML tags: Element-specific, global, and event handler content attributes. The attributes that you can add to this tag are listed below.

 

<command type="command|checkbox|radio">

 

If a <command> element slave has a command attribute, and slave is in a Document, and there is an element in that Document whose ID has a value equal to the value of slave's command attribute, and the first such element in tree order, hereafter master, itself defines a command and either is not a <command> element or does not itself have a command attribute, then the master command of slave is master.

 

An element with a command attribute must have a master command and must not have any type, label, icon, disabled, checked, or radiogroup attributes.

This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

  1. command is the abstraction behind menu items, buttons, and links. Once a command is defined, other parts of the interface can refer to the same command, allowing many access points to a single feature to share aspects such as the disabled state.
  2. The command element is meant to encapsulate something that you can do. It can be rendered within a menu (since a menu presents items you can invoke).
  3. It provides an abstraction layer between UI and commands, so that you can make multiple UI elements refer to the same command. 
  4. This gives you the flexibility of having one command element, rendered in a menu, that is also invoked via a URL in the middle of the page as well as a button at the bottom of the page. Disabling the command disables all access paths (url/button/menu) to the action behind the command.
  5. The <command> element is meant to be an abstraction to let you refer to the same "command" from multiple menu entries or buttons.
  6. The <command> is supported only in IE9 browser.
