I have a simple eRb snippet that get''s a hash via an objects method call, and populates a Javascript call... for example: <head> <script src="http://www.asdf.com/asdfasfd.js"></script> </head> <body> <%= @hash = asdf.getHash() %> <script> blah.doSomething(<%= @hash[''blah''] %>); </script> </body> When I view the source of the resulting HTML, the doSomething() method is indeed populated with the correct value from the hash... however, the actual method get''s called "without" the value. So, I''m assuming that there is some reason the Javascript is being rendered and executed prior to the eRb code. Is this correct ? Any insight into this would be appreciated ! _______________________________________________ Rails mailing list Rails-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org http://lists.rubyonrails.org/mailman/listinfo/rails

I''m actually extracting the values from the hash above the script... so: # Get the Hash from the Method <% @location_hash = @listing.getData %> # Assign "@stuff" the value of the stuff value in the Hash <% @stuff = @location_hash[''stuff''] %> # Use "@stuff" in the Javascript new RandomJavascriptObject(<%= @stuff %>); The catch is, if I hardcode the value of @stuff in the actual HTML, and load the page... everything works fine. If I use eRb to do the printing like above, the value is actually printed in the HTML, but the actual value passed to the Javascript is empty.

The parameter for the Javascript Object is a number. I tried doing @ stuff.to_i and @stuff.to_s, but no luck.

Hmm.... no luck. I''m baffled :) The HTML source has the function and the parameters on the same line: new BlahObject(1234, 1234); ... and if I hardcode the parameters to replicate the above, everything works out perfectly. So, I''d have to assume that this is a "Javascript loading before eRb" issue... or something similar. I''ll keep trying different options to see if I can''t nail this down.

I just tried doing a custom "render", and also put the Javascript call with hardcoded values in a file to "render_partial"... but no luck. WTF.

Anybody have any ideas ? Just trying to pass a parameter into a Javascript method. Simple stuff, but it seems impossible !

it will work if you wait until the page has loaded before calling the javascript
function:
<body onload="myjavascriptfunction(''<%= @some_msg
%>'')">
it works for me, but not, as you have pointed out, when you try to call
javascript
before the page has finished loading.
>script/about
About your application''s environment
Ruby version 1.8.3 (i386-cygwin)
RubyGems version 0.8.11
Rails version 0.14.3
Active Record version 1.13.0
Action Pack version 1.11.0
Action Web Service version 0.9.3
Action Mailer version 1.1.3
Active Support version 1.2.3
I have noticed that for some reason beyond my understanding javascript functions
work
more consistently when placed either in the HEAD or "included" within
the HEAD (not w/in the BODY).
And some of the most common javascript errors are caused by race conditions
(e.g. page loading),
which is why I always wait for the page to load before calling any javascript.

Simple stuff, but it seems impossible !Perhaps your web server is delivering the function name and parameters in different response chunks because of possible long delays in erb output, and your web browser is not waiting for all the chunks before evaluating the script section. Try generating the whole script section in erb: <%= javascript_tag "new RandomJavascriptObject( #{@stuff} );" -%> -- We develop, watch us RoR, in numbers too big to ignore.
