I’d like to conserve the sum total of several text fields on my form,
even as I set them to blank upon a user link action.
The following in-line snippet fails to store the value of my sum total
field locally for eventual reassignment. (I am re-assigning it because
the fields all have an observe_field nexus relating them, which
<%= link_to_function “Itemize expenses” do |page|
local_var = page[:operating_expense_admin_total].value
page[:operating_expense_admin_other].value = “”
page[:operating_expense_admin_advertising].value = “”
page[:operating_expense_admin_management_fee].value = “”
page[:operating_expense_admin_total].value = local_var
What is the proper way to extract values, store them locally and
reassign them , per the attempt above?
