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

def loadCustomLinks
@team_links = "<a href=''#''

end
end
# javascript

function displayLogo(name)
{
// De-select last selected item
document.images[lastName].src = "/images/" + lastName +
".png";
// Highlight team icon
document.images[name].src = "/images/" + name +
"_hover.png";
// Activate team banner
document.images["logo"].src = "/images/logo_" + name +
".png";
// Re-activate siteBanner (TEMP FIX)
document.images["siteBanner"].src =
"/images/logo_dashboard.png";
// Set lastName
lastName = name;
} // end displayLogo()
#layout.rhtml

<%= link_to(image_tag(''/images/banner_team1.png'',
:id => ''bannerImgAlign'', :name =>
''banner_team1'',
:style => ''border:0'', :onclick =>
''displayLogo("banner_team1")''),
:action => ''loadCustomLinks'') %>

Since the page loads any temporary javascript changes you made to the page are blown away. If you''re want to do things like this you can drop the javascript completely. Just make your loadCustomLinks view display the right images.

However you say an appropriate value is not returned, and I thought using ''return false;'' would essentially ignore the redirect action, which it doesn''t... Also, I see 2 ways I can proceed with your suggestion: 1) Invoke the javascript method(s) through my loadCustomLinks method 2) Translate the javascript code to ruby code and place it in loadCustomLinks ...I don''t think there is a straight-forward way to do #1 without adding plugins I would rather do #2 as it seems a better alternative. Could you help me get started with how to write the code for this method? -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Then in your layout/view it''s just a case of using that parameter (probably assigned to an instance variable first) to make all those links to the various images.
