but this was just to write to explain.
please don't look grammar itself.
My point was legal javascript object didn't invoked.
my real codes are something like below
function myclass() {
var open = function() {
}
}
var obj1 = new myclass;
and then in the link_to_remote :before=>'obj1.open();'
but obj1 is not defined error raised.
and could you explain how to deal with ajax request to implent that
insert javascript function before and after of redirect_to action?
thanks.
