Hi all,
As promised, here is the second topic I wanted to ask about:
Are there any plans, or is there any current way to subclass the
jQuery object? I've been doing a lot of digging around and I've seen
some talks about it, and there have been some questions about what the
use would be, but I've found a use case, and me, Paul, and Eduardo
have all tried to figure out a way, but to no avail.
Here is the use case:
I want to create a function that behaves exactly like jQuery, except
that it does some slightly different things, and be able to extend it
without worrying about what the parent jQuery object is doing, or what
plugins have been loaded globally.
The benefits are that it would use the prototype chain, so it would be
memory efficient, and it would be a way to add plugins without them
being clobbered by other plugins.
So, I've tried a bunch of stuff:
var subClass = function(sel, context){
return new subClass.fn.init(sel, context);
}
subClass.fn = subClass.prototype = new jQuery.fn.init;
subClass.fn.init = subClass.prototype;
and I've tried so many different variations of this, but anytime I try
to do:
subClass.fn.test = function(){}
it, without fail, creates jQuery.fn.test.
To show what I am trying to do, I'll give an example:
jQuery.fn.plugin1 = function(){
console.log('I am global, everyone can see me');
return this;
} // globally available plugin
subClass.fn.plugin1 = function(){
console.log('I am local, and I am only run when using the subclass');
return this;
} // my own local plugin
so you could do:
jQuery('body').plugin1(); // prints 'I am global, everyone can see me'
subClass('body').plugin1(); // prints 'I am local, and I am only run
when using the subclass'
However, namespaced plugins is only one advantage. Being able to
attach custom static methods, etc, would be incredibly useful.
Does anyone know of a way to subclass the jQuery object using it's
prototype?
Thanks again for reading all of this. I truly appreciate it,
