<% if params[:section] == 'orders_bar' %>
  $("#orders-bar-section").html("<%= escape_javascript(render partial: 'dashboards/orders_bar', locals: { widget_data: @orders_bar, url: admin_dashboard_path }).html_safe %>");
<% elsif params[:section] == 'sales_bar' %>
  $("#sales-bar-section").html("<%= escape_javascript(render partial: 'dashboards/sales_bar', locals: { widget_data: @sales_bar, url: admin_dashboard_path }).html_safe %>");
<% else  %>
  $("#orders-bar-section").html("<%= escape_javascript(render partial: 'dashboards/orders_bar', locals: { widget_data: @orders_bar, url: admin_dashboard_path }).html_safe %>");
  $("#sales-bar-section").html("<%= escape_javascript(render partial: 'dashboards/sales_bar', locals: { widget_data: @sales_bar, url: admin_dashboard_path }).html_safe %>");
<% end %>

信息：这些部分是在标签内的“admin.html.slim”上进行的 ajax 请求上加载的。

（对于 turbolink/non-turbolink 访问 admin.html.slim）当 admin.html.slim 被加载时，$.ajax 方法被调用了两次，它直接在标签内。为什么它被调用两次？

谢谢你。
