I have a list of html input items in my html page each representing different model. On click of the submit button, I would like to send all the details as a json object to the controller. From the controller, I would like to return the js code to the browser.
As far as the examples I have seen, they are either sending the data as json and receive json from the server else send the data using form_for and receive the js code from the server. But I would like to send json and receive back js code. How i can do this in rails 3.1 using jQuery?
I believe this Railscast by Ryan Bates provides detailed instructions for doing exactly what you are describing.
Railscast Episode #136 – JQuery
That was the railscast I used when I was first learning to post data using jquery in a JSON format and return javascript. It was really helpful.
Though the Rails version is not 3.1, you should be able to adapt the ideas quickly.
