Ruby on rails 如何将其添加到rjs？

我知道这个命令在语法上有点不对劲

 page << "$('.places').append('<%= escape_javascript(render(:partial => 'contact', :locals => {:contact => @contact, :something => @something, :checked => false, :sale => @sale.item.to_s})) %>');"    

page使用原型（Rails 2.3）

使用jQuery（Rails 3）

$（“.places”）.append（“{:contact=>@contact，：something=>@something，：checked=>false，：sale=>@sale.item.to%>”；
您使用的是哪个版本的rails？
page.select(".places").each  do |element, index|
  page.insert_html :bottom, element, :partial => 'contact', :locals => {:contact => @contact, :something => @something, :checked => false, :sale => @sale.item.to_s}
end

$(".places").append("<%= escape_javascript render 'contact', :locals => {:contact => @contact, :something => @something, :checked => false, :sale => @sale.item.to_s} %>");
