well, you have to change this:
<%= hidden_field_tag ‘blah’, 42, :id=>‘fc’ %>
to access it as params[:blah] in your controller.
Hope that helps:)
Usually using javascript I can access a hidden field value using:
document.formName.fieldName.value. Please correct me, in this case the
formName = par2 and what is the fieldName ? Is it fc1 or fc2?
Let’s say it is fc1, when I do document.par2.fc1.value = 12, Will 12 be
the value of params[:fc1] in my controller?
I come up to this question because I want to pass value from javascript
to ruby, and thinking that I can just put the javascript value to hidden
field and let rails grab the value from hidden field
Thank you for replying
