prototype Element.observe handler function - how to add more arguments in addition to event handler ?
$(id).observe(''click'', this.add( ''name''
).bindAsEventListener(this));
As we know, event handler passed as argument to handler function.
Sample above not correct, but how to add ''name'' string
argument to
handler function?
