When I click the submit button, I am rendering with json in controller.
My json is {notes: array[1], array[2]}. Now I am rendering view.html.erb file.
I want to show the values in notes like <%= notes %> in this file, how to display it ?

1what about the loop through array . js file and add values in html.erb with .appendChild()?bad_kotya– bad_kotya2020-07-01 11:01:32 +00:00Commented Jul 1, 2020 at 11:01

The json you are showing is invalid json syntax. Also note that the json is in javascript on the client side, and your controller is on the server side. As @bad_kotya points out, you don't need to send the data to the server side only to be rendered back to the client side. You can use javascript to render the data in the DOM directly.lurker– lurker2020-07-01 11:35:58 +00:00Commented Jul 1, 2020 at 11:35

If notes is an arary you can loop over it and display the content in your .erb.html file as below:
<div>
<% notes.each_with_index do | note, index | %>
<div id="title">
<%= note[:title] %>
</div>
<% end %>
</div>5 Comments

@SNandy Does your
.html.erb file has access to notes?rishabh0211
The
notes variable is in JS (.js) file or in ruby (.rb) file? If it is ruby file, you can proceed as @Viktor suggested, create an instance variable in your controller and use it in your view.sounds like you are confusing JSON requests with HTML request.
The incoming request should be a HTML
controller
# GET /the_controller/view
# not /the_controller/view.json <- wrong
def view
@notes = array
end
view.html.erb
<%= @notes %>
see @rishabh0211 answer for better presentation
if indeed you intend this to be a json request, through som ajax request or similiar, you need to specify that in your question.
