Ruby on Railsで初めてアプリを作っている初学者です。ajax通信ができず困っています。  
jQueryを使って下記の通り作成しました。発火は起きていますが、controllerへ送られていないような感じです。  
解決策見つからず、ご教示のほど、お願いいたします。

search.js

```

    $(function() {
      var search_list = $("contents.row");
      function appendCompany(company) {
      $(".search-form").on("submit", function() {
        var input = $(".search-input").val();
        console.log(input);
        $.ajax( {
          type: 'get',
          url: '/searches',
          data: { keyword: input },
          dataType: 'json'
        })
        .done(function(companies) {
         })
        .fail(function() {
          console.log("失敗です");
        });
      });
    });
    
```

searches_controller.rb

```

      def search
        @companies = Company.where("name LIKE ?", "%#{params[:keyword]}%")
        respond_to do |format|
          format.html
          format.json
        end
      end
    
```

index.html.erb

```

        <div class="search-form">
          <%= form_tag search_user_searches_path(current_user), :method => 'get' do %>
            <%= text_field_tag :keyword, "", placeholder: "投稿を検索する", class: "search-input" %>
            <%= submit_tag 'Search', class: 'search_btn' %>
          <% end %>
        </div>
    
```

rails routes

```

question
ruby-on-rails jquery ajax
ajax通信がうまくいきません。
`url: '/searches'`  
が route に存在してないですね  
`url: $(this).attr('action')`  
にしないといけないのでは？

あと普通 rails で ajax するときは form に remote: true ってつけるだけで勝手に ajax になります  
js のビューを書くことで JSON 受取処理も書く必要がなく直接 ajax の結果を JS として実行できるので便利です
