I am learning Rails 3 and need some help on Ajax part. I am trying to accomplish the following: There is a textarea on the page which has a length of letters constraint, say 100. Every time a symbol is typed there,a nearby label tells you how many letters you have left.
I plan to use Ajax to do this. I googled for a few hours and could not figure out how to do this. So far what I have done is the follows: Step 1. Add :remote => true to the form_for method. This form_for method lives in a partial which is called in app/views/foos/home.html.erb Step 2. Add respond_to do |format| format.html format.js end to FoosController's corresponding Home action. Step 3.create home.js.erb under app/views/foos/ But I do not know how to add something so when a letter is typed in a textarea inside the form generated by form_for method that home.js.erb will process. Could someone help me out here? -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
