How to send data via AJAX in Rails?

Question

JavaScript

Hello!

There is a page with products, each product has a "Details" link, and a data-id containing the product id is attached to each link.

I have an item_search_by_id(id) method that takes an item id and searches for all item information by id.

I don’t understand how I can pass data-id to the method and get a response. Tell me please

You must have a route created to receive data by ide, there must be a method in the controller, and then just an ajax request (coffeescript code):

item_id = $(element).data('id')
$.ajax
      url: 
      type: 'get'
      data: { 'item_id': item_id }
      dataType: 'json'
      success: (response) ->
         ...
      error: (response) ->
        ...
