Question

I’m doing some Rails stuff with AJAX (not using UJS, but rather rolling my own AJAX). My action looks like:

# DELETE /votes/1
# DELETE /votes/1.json
def destroy
  @vote = Vote.find(params[:id])
  Comment.increment @vote.comment_id, :up_votes => -1
  @vote.destroy

  respond_to do |format|
    format.html { redirect_to votes_url }
    format.json { head :ok }
  end
end

This action is being called via JavaScript ala:

   ajaxOptions = {
      url: $(this).attr("href"),
      type: $(this).attr("data-method"),
      data: {
        comment_id: $(this).attr("data-comment_id"),
        _method: 'delete'
      },
      success: function(response) {
        return someFunc();
      }
    };
    $.ajax(ajaxOptions);

However, what happens is the action redirects to the vote list page. I want it to not redirect at all just return some positive status to the JavaScript so that my someFunc() can execute without issue.

How would I accomplish this?

Change your respond_to handler to Javascript instead of JSON:

respond_to do |format|
  format.html { redirect_to votes_url }
  format.js { head :ok }
end
