The effect I''m trying to achieve here is basically as follows:
test_controller.rb
----------------
class TestController < ApplicationController
def test
end
def fetch
@array = [1,2,3,4,5,6,7,8,9]
end
end
fetch.rhtml
------------
<p>TEST<p>
<%= x=0 %>
<script>
for (var i=0; i<10; i++) {
document.write("Test - " <%= @array[x]; x+=1 %>);
}
</script>
And this would generate the output of..
Test - 1
Test - 2
Test - 3
ect.
However it fails miserably :(
Instead it just prints Test - 1 10 times, so its basically interpreting
the x+=1 wrong.
Any suggestions are much appreciated,
Thanks,
- Jon

You either need to make that array exist in javascript land and then just iterate through it in javascript or do the iteration in your view itself (ie something like <% @array.each do |value| %> document.write("Test - <%=value%>") <% end %> Fred --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
