I tried following Ryan Bates'' railscast on rjs tips
(http://railscasts.com/episodes/45-rjs-tips) and apply his method of
using if-else inside the rjs template, but can''t seem to get it to
work.
Basically, I''m trying to toggle the text on a link when it''s
clicked
(test.js.rjs):
page << "if ($(''test_link'').value ==
''one'' {"
page.replace_html ''test_link'', ''two''
page << "} else {"
page.replace_html ''test_link'', ''one''
page << "}"
I believe I have the necessary view and controller code:
<%= link_to_remote ''one'', :url => { :action =>
''test'' } %>
and
def test
respond_to do |format|
format.js
end
end

Look closely and see how you forgot the ")" after "''one''". Javascript is very punctuation sensitive, you need to pay special attention to it. Also, use Firefox for testing and install Firebug to debug your javascript. It would have indicated this error.

I changed my code to include the closing parenthesis, but it seems to not work still. I am using firefox w/ firebug, although I''m still not that seasoned in debugging js - I''ll read up on that. Here''s what I have now: page << "if ($(''test_link'').value == ''one'') {" page.alert(''hello!'') page << "}" -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Peter - Using firebug, I tried typing in the console the following:>> console.log($(''test_link'').value)undefined>> console.log($(''test_link'').innerHtml)undefined I tried just using a simple span <span id="test">hello</span> to see if console.log works, and I get the same ''undefined'' message, even though it''s showing in the page markup. I don''t want to make this an issue and take up anymore of your time -- I guess I need to improve on my javascript.
