I was working on some event handling
and I came across something that I was not quite sure of. What is the different
between the 2 following pieces of code.
$('#abc').click(function(){
});
|
$('#abc').bind('click',function(){
});
|
I did some searching and came across
this explanation on Stack Overflow. Basically
the answer was look at the source, so I did. If you look at the source for
jQuery you will see the following code.
jQuery.each( ("blur focus
focusin focusout load resize scroll unload click dblclick " +
"mousedown mouseup mousemove
mouseover mouseout mouseenter mouseleave " +
"change select submit keydown
keypress keyup error").split(" "), function( i, name ) {
// Handle event binding
jQuery.fn[ name ] = function( data,
fn ) {
if ( fn == null ) {
fn = data;
data = null;
}
return arguments.length > 0 ?
this.bind( name, data, fn ) :
this.trigger( name );
};
if ( jQuery.attrFn ) {
jQuery.attrFn[ name ] = true;
}
});

Basically for every one of those
short hand event names, it is calling bind. So really there is no difference,
so then I started asking myself, should I ever call the shorthand? I know there
probably is not a huge difference but there has to be some performance benefit
to using bind right? What do you guys think?
