Get firefox, and install firebug, its a must have for debugging any javascript related problems. Also, I would recommend finding a tutorial that is a little newer, as Ruby as a language and rails has changed a whole heap since I wrote this tutorial a few years ago, some of the stuff mentioned here probably isn’t relevant at all anymore.

Even better, if your looking to do anything on screen in the browser, just learn and implement your code in Javascript. Its what its for. You could implement this kind of functionality with a few lines of Javascript.

Goodluck,

Sorry I’m relative new to ruby on rails.

I used the example you presented. However, when I view the webpage and click the checkbox it sometimes doesn’t work, and then i refresh the page and then it works. I’m currently using eclipse with the ruby on rail plug-in to develop and the browser.

However, with a normal browser I can never get an action with clicking the checkbox. Is there something i’m not enabling in the real browser?

Do you know anything that would explain how it would work sometimes and something not. I’m set to development mode in my ruby on rails app. Is it some ruby on rails setting? browser setting?

In addition, how would you use the observer_field (show/hide) with a link or a button?

Thanks,
D
