I''ve come up with a patch to PeriodicalExecuter which allows for pausing and restarting without losing the time remaining. I''ve searched for something like this, but the only one I found linked to a dead blog.

Hi, This is Atit here. I am working on Ruby on Rails. I have one functionality in which, I have two drop down. Second drop down list is dependent on first one. So changing value of first drop down is refreshing the second drop down. I have used observe_field to implement this functionality.

Hi all, I just started using prototype 1.3.1. I''ve successfully used Form.Element.EventObserver on a select list and recently tried to add it to radio options. However, I think there is a flaw in how it works with radio options. Radio options are a little unusual in that there are multiple distinct elements, tied together by a common name, where changing one element causes a
