Currently, I allow my users to dynamically add new fields to a form
using the link_to_function variable. However, whenever a new field is
added, its inputs have the same names as the previous fields. I
solved this by passing in a local variable, but I can't get that value
to increment (or update) on click.
I'm using the following code:
<%= link_to_function "Add Another" do |page|
page.insert_html :bottom, :tasks, :partial => 'stuff', :object =>
Model.new, :locals => { :num => 1 }
end%>
(Yes, that code was take from ryan bates's complex forms series.)
How do I get that :num => 1 to increment every time a user clicks "Add
Another." increment and increment! don't seem to work, and I thought
about using Time.now.to_i instead of single digit integers (note: it
doesn't matter what "num" is as long as it's a number), but that only
loads the time when page is first loaded, and doesn't update when "Add
Another" is clicked.
So, is there anyway to increment this :num value using client side
javascript?
