I've written a plugin for jQuery to handle right click events.

The plugin provides two features:

$( ... ).disableContextMenu( condition_event );

This function disables the browsers build-in contextmenu (right-click menu on PC's).

condition_event  - is an optional parameter, it's meant to be a function-reference to determine if the contextmenu should be shown, the function must return true if the menu is allowed to be shown and must return false if the menu is not to be shown. If condition_event is not provided or returns a non-boolean value, the contextmenu will be disabled.

Please note: This is not a way to stop your users from downloading images or viewing source code, this is only meant to be used as when it's better for the usability.

$( ... ).rightClick( callback, contextmenu_condition_event );

This function will let you create your own event for right click, it can be used to create your own contextmenu.

It takes two paramters.

callback - Is the event which will be called on right click. (required)

contextmenu_condition_event - will be parsed to disableContextMenu.

Extra functions:

I also provide functions to remove these event from an element:

$( ... ).enableContextMenu( );

Will undo the function $( ... ).disableContextMenu( );

$( ... ).removeRightClick( );

Will remove the rightClick event from the element.
