With jQuery is very simple make new event plugins. This is a sample
plugin that I made
for my organisation: (sorry comments in spanish :$)
/**
* @fileoverview
* Crea nuevos eventos para la pulsación de las teclas:
* INTRO, DELETE, ARROWS, PAGINA arriba y abajo
*
* @author ATICA
* @version 0.1
* @requires jQuery.js
*/
jQuery.fn.extend({
/**
* Evento para la pulsación de la tecla Intro
* @param {function} función a ejecutar en el evento
*/
intropress: function(f){
$(this).bind("intropress",f);
$(this).keydown(function(e){
if(e.keyCode==13){ $(this).trigger("intropress");}
});
return this;
},
/**
* Evento para la pulsación de la tecla Suprimir
* @param {function} función a ejecutar en el evento
*/
deletepress: function(f){
$(this).bind("deletepress",f);
$(this).keydown(function(e){
if(e.keyCode==46){ $(this).trigger("deletepress");}
});
return this;
},
/**
* Evento para la pulsación de la tecla flecha izquierda
* @param {function} función a ejecutar en el evento
*/
leftpress: function(f){
$(this).bind("leftpress",f);
$(this).keydown(function(e){
if(e.keyCode==37){ $(this).trigger("leftpress");}
});
return this;
},
/**
* Evento para la pulsación de la tecla flecha derecha
* @param {function} función a ejecutar en el evento
*/
rightpress: function(f){
$(this).bind("rightpress",f);
$(this).keydown(function(e){
if(e.keyCode==39){ $(this).trigger("rightpress");}
});
return this;
},
/**
* Evento para la pulsación de la tecla flecha arriba
* @param {function} función a ejecutar en el evento
*/
uppress: function(f){
$(this).bind("uppress",f);
$(this).keydown(function(e){
if(e.keyCode==38){ $(this).trigger("uppress");}
});
return this;
},
/**
* Evento para la pulsación de la tecla flecha abajo
* @param {function} función a ejecutar en el evento
*/
downpress: function(f){
$(this).bind("downpress",f);
$(this).keydown(function(e){
if(e.keyCode==40){ $(this).trigger("downpress");}
});
return this;
},
/**
* Evento para la pulsación de la tecla página abajo
* @param {function} función a ejecutar en el evento
*/
pagedownpress: function(f){
$(this).bind("pagedownpress",f);
$(this).keydown(function(e){
if(e.keyCode==34){ $(this).trigger("pagedownpress");}
});
return this;
}, /**
* Evento para la pulsación de la tecla página arriba
* @param {function} función a ejecutar en el evento
*/
pageuppress: function(f){
$(this).bind("pageuppress",f);
$(this).keydown(function(e){
if(e.keyCode==33){ $(this).trigger("pageuppress");}
});
return this;
},
});

I recently created an plugin/extension for jQuery to use the following
syntax for binding events.
$('input').bind('mouseover focus', fn);
So you can bind multiple event types to the same function quickly. It
also applies to .one and .unbind.
However, this got me thinking about writing a plugin that would allow
us to add new event types ... like mouseenter and mouseleave. So
instead of using .hover, you could do this:
$(...).bind('mouseenter', fn);
or
$(...).bind('mouseenter', fn1).bind('mouseenter', fn2);
or
$(...).unbind('mouseenter', fn1);
or
$(...).trigger('mouseenter');
etc...
So I'm curious about what the jQuery community thinks about this idea?
I've built out a proof-of-concept but it is by no means production
ready. You can see it in action here:
http://www.brandonaaron.net/jquery/plugins/events_extension/test/test.html
We could also hook up the mousewheel event in the same way.
$(...).bind('mousewheel', fn);
Are there other events that could be added/normalized with this plugin?
BTW ... Here is the blog post about binding multiple event types:
