如何更改JavaScript中的Rails默认“破坏”操作？

Question

I would like to change the default functionality Rails uses for the destroy action by adding ajax and an animation to remove the item. I know how to implement the javascript, but I'm not sure what is the best way to "tap in" or override this bit of javascript, especially now that the jquery_ujs file is vendored away somewhere due to the asset pipeline. What is the best practice for doing this?

Answer 1

You can still add ajax and animation without bothering about the rails default behavior or the ujs behavior.

In the destroy action, you just have to respond to a javascript request and create the necessary js file that does the animation magic using jquery.

def destroy
  # perform destructive action (optional)
  respond_to do |format|
    format.js
  end
end

Make sure there's a file called destroy.js.erb in the views/<controller_name>/ folder.
