I don't know in which case an each over a definition (prototype with a
length) could be useful ... I think a forEach as for in could be explicit
and less ambiguous for these weird case (I mean, you have the same problem
with window object, don't you?)
A=0;$.each(window,function(){ A++; });A
... A is 0
what about this?
forEach:function( object, callback, args ){
if ( args )
for ( var name in object )
if ( callback.apply( object[ name ], args ) === false )
break;
else
for ( var name in object )
if ( callback.call( object[ name ], name, object[ name ] )
=== false )
break;
},
// args is for internal usage only
each: function( object, callback, args ) {
var i = 0, length = object.length;
if(length === undefined)
jQuery.fn.forEach( object, callback, args );
else if(args)
for ( ; i < length; )
if ( callback.apply( object[ i++ ], args ) === false )
break;
else
for ( var value = object[0];
i < length && callback.call( value, i, value ) !==
false; value = object[++i] );
return object;
},
