Hello,

I am new to Ruby and I am currently creating a webpage which lists bug  
_stats_ information for various development teams. Each team is  
represented on the page with an image.  
When a team’s link is clicked, I want 2 things to happen:

1. Javascript needs to call the displayLogo() method to handle visual  
effects
2. Ruby needs to call the loadCustomLinks() method to display a link

Current Behavior: When a team link is clicked, the javascript effects  
appear  
and then disappear, followed by the display of the  
team’s  
custom link.

Expected Behavior: When a team link is clicked, I want the javascript  
effects  
to STAY active after the custom link is displayed.

I expect that my issue is more related to Javascript than to Ruby, but I  
also want to make sure that I am using good Ruby programming  
practices…

Any help is appreciated,

JT

// Set lastName
lastName = name;
} // end displayLogo()

I’m guessing that when you say “Ruby” you mean “Ruby on Rails,” in which  
case the RoR mailing list is going to be more helpful than this list.  
Ruby is a general purpose programming language. Ruby on Rails is a web  
application framework written in Ruby.

Check [Ruby on Rails — Community](http://www.rubyonrails.com/community) to find out more about the  
RoR mailing list.

Good luck!

Ah, didn’t know that, thanks!
