Hi,
I''ve been looking around on the forums and tutorials but I still
can''t
seem to make this work.
Here is what I am trying to do.
I have a view do a form_remote_tag with some variables. In the
controller I want to create an array, fill it with values, and when the
function returns I want to call a javascript function with this array.
currently this is what I have that doesn''t work
******** view *******
<script type="text/javascript">
function javascript_functionA(items){
//do things with items
}
</script>
<% form_remote_tag :complete =>
"javascript_functionA(''#{myArray}''),
:url => {:action => :controller_functionA} %>
******** controller *******
class MyController < ApplicationController
def controller_functionA
myArray = ["so", "many", "exciting",
"things"]
end
end
I know I must be doing something wrong but being new to rails there just
seems like to many places where I could be messing things up.
Thanks for the help,
Lee

Looks like ''#{myArray}'' is giving just one parameter (''value1''). You may have to reference each array value by its indices.
