[Proto-Scripty] Binding functions to $$ directly
How come I got to this
$$('#div1 p span.someclassName').each(function(el)
{
Event.observe(el, 'click', function(event)
{
alert('a');
});
});
instead of something like this ?
$$('#div1 p span.someclassName').observe('click', function(el)
{
alert('b');
});
Any way to get the latter to work like in jQuery ?

How 'bout
$$('#div1 p span.someclassName').invoke('observe', 'click',
function(el)
Close enough?

Re: [Proto-Scripty] Binding functions to $$ directly
jQuery conflates the meaning of $ and $$ in a useful manner, but
Prototype provides the invoke function to shortcut what you are doing
here.
$$('#div1 p span.someclassName').invoke('observe','click', function(el)
{
alert('b');
});
To my mind, it's a little less magic and a lot more intentional. Note
also in this case that where you have el, the reference is really to
the click event, so I would write this as function(evt) just to note
that. Prototype also scopes 'this' inside of your looped function, so
if you wanted to alert(this), you would get the individual span
element as your value.

Re: [Proto-Scripty] Binding functions to $$ directly
Jquery also references this inside the function as the object / element
clicked..
