  - handler
    Type: Function( Event eventObject )
    A function to execute each time the event is triggered.

- #### version added: 1.0.contextmenu()

  - This signature does not accept any arguments.

This method is a shortcut for `.on( "contextmenu", handler )` in the first two variations, and `.trigger( "contextmenu" )` in the third. The `contextmenu` event is sent to an element when the right button of the mouse is clicked on it, but before the context menu is displayed. In case the context menu key is pressed, the event is triggered on the `html` element or the currently focused element. Any HTML element can receive this event. For example, consider the HTML:

1 2 3 |
    <div id="target">  Right-click here</div>

The event handler can be bound to the `<div>` as follows:

1 2 3 |
    $( "#target" ).contextmenu(function() {  alert( "Handler for .contextmenu() called." );});

Now right-clicking on this element displays the alert:

`Handler for .contextmenu() called.`

To trigger the event manually, call `.contextmenu()` without an argument:

1 |
    $( "#target" ).contextmenu();

### Additional Notes:

- As the `.contextmenu()` method is just a shorthand for `.on( "contextmenu", handler )`, detaching is possible using `.off( "contextmenu" )`.

## Examples:

To show a "Hello World!" alert box when the contextmenu event is triggered on a paragraph on the page:

1 2 3 |
    $( "p" ).contextmenu(function() {  alert( "Hello World!" );});

Right click to toggle background color.
