Hi,
I encountered a scenario wherin if i do

$$(some selector).each(function(node){
    someFunction(node, this)

}).bind(this)

, the 'this' object within someFunction() is not the original context
that i bound the 'each' function to.

Can you please explain?
Thanks

Hi,

You're calling #bind on the return value from #each, which is
incorrect -- #each returns the enumerable object, which doesn't have a
#bind method.

What you're looking for is the second _parameter_ to #each, details in
the docs[1].

[1] http://api.prototypejs.org/language/enumerable.html#each-instance_method

HTH,
