| Parameters |
|
this.isButton( button ) → boolean
booleanTests to see which button was pressed during the event. This is really only useful in IE and Gecko browsers. And in IE, it's only useful for mousedown/mouseup events, because click only fires for the left mouse button.
Safari 2 only reports the left button being clicked, and uses the value '1' instead of 0. Opera only reports a mousedown event for the middle button, and no mouse events for the right button. Opera has default behavior for left and middle click that can only be overridden via a configuration setting.
There's a nice table of this mess at http://www.unixpapa.com/js/mouse.html.
