A developer that's recently joined my team is new to Prototype and is
finding himself trying to do things in a jQuery-ish way, for example:
$$('.panel').addClassName('red').addClassName('blue');
I explained the differences between the Prototype and JQuery ways of
doing things, and demonstrated that the same result could be achieved
using Prototype with not a great deal more code:
$$('.panel').invoke('addClassName', 'red').invoke('addClassName',
'blue');
At the same time I noticed the NodeList present in the BBC's new Glow
library (see here:
http://www.bbc.co.uk/glow/docs/1.5/api/glow.dom.nodelist.shtml
), and wondered whether Prototype could benefit of a similar module to
allow the element methods to be invoked on a collection of DOM nodes
(the return of $$) and chained together jQuery-style.
A real basic implementation could look something like this, only less
lame....
var NodeList = Class.create(Enumerable, {
initialize : function(elements){
this.elements = elements;
},
_each : function(iterator){
this.elements.each(iterator);
},
item : function(i){
return this.elements[i];
}
addClassName : function(className){
this.elements.invoke('addClassName', className);
return this;
}
// More methods here....
});
I don't think Prototype needs to make itself like jQuery, and I'm not
looking to start that debate here. I am however interested to hear if
anyone thinks there is any value in this approach, or indeed if not.
Personally I think it would do well to make Prototype more accessible
to newcomers.
Thanks,
Mike.
