Question

我迷失了如何让这部分渲染。它取代<table id="tab">中的同一结构。如果这还不够，请告诉我。

错误

<强>控制器

  def p_sort
    column = lambda { |a,b| a.percentage <=> b.percentage }
    @holdings = session[:holdings] 
    @holdings = @holdings.sort! &column
    @holdings.reverse!
    respond_to do |format|
      format.js { render 'tsort' }
    end
  end

  def tsort
    respond_to do |format|
      format.js
    end
  end

调用控制器/模板中的两个方法丢失
