jquery - Coffeescriptがajaxを処理しない：成功

Answer 1

OK, got it. I needed to make two changes:

• First, as suggested by this answer, I needed to be returning a text/json MIME type on the response. My action previously looked like this:

  def edit
    respond_to do |format|
      format.js
      format.html
    end
  end

To get a text/json response I wound up with this:

  def edit
    respond_to do |format|
      format.js { render :json => { :html => render_to_string('edit')}, :content_type => 'text/json' }
      format.html
    end
  end

That change triggered ajax:success and therefore ran the open-modal functions.

• However, because the response payload was now in data.html rather than just data, I needed to tweak the modal.js.coffee to actually put markup in the modal:

  .html(data.html) // instead of .html(data)
