Ajax comment submission form in Rails. How to clear it after sending, if there are several forms?

Question

Ruby on Rails

There are several items on the page, each has comments and a comment submission form.
How to make the form empty again after submitting a comment via Ajax.
This option only works for the first form:
$("#comment_content").val('');
Each form needs its own unique id, but how do I do that?
You can set a unique id for the form div, like id="comments_form_<%= item.id %>, but the above method only works for the form, not the div.
Are there other options?

Answer 1

figured out
item_<%[email protected]%>_comments_form is the id inside which is the comment submission form with id comment_content

Answer 2

And do you have all input fields have the same id? Do you notice anything strange?
