Question

As the title, I want to abstract some function and share them between different unobtrusive javascript files. How can I do?

To be more specific, for example, I have two files: show.js.erb, create.js.erb in views/object/

When I response to ajax request, I will render them.

Now this two files share some same code, so I want to abstract them and put it to a new file.

How can I achieve this?

Like with html.erb files you can also have partial for js.erb files.
Just extract the common code into a partial (starting with a _, so e.g _common_code.js.erb in views/object/).
Then you can just use the render function in the show.js.erb or create.js.erb files like this to include your common code.

render "common_code"
