代码正确缩进位置以下，spa

extend "layout"

block 'content',->
   div ->'nihao'
   script id:"InvoiceItem",type:"text/template",style:"display: none",->
        div ->"{{price}}"
        div ->"{{quantity}}"
        div ->"{{amount}}"
   coffeescript ->
      $ ->
        invoiceItemModel = new InvoiceItemModel({price:5,quantity:3})
        (new PreviewInvoiceItemView({el:'body',model:invoiceItemModel})).render()

缘由：引用了extend "layout"模板之后，要操做当前页面的代码，应该放在当前页面代码的内部，放在外部是访问不到的，因此报错：Uncaught TypeError: Cannot read property 'replace' of undefinedcode
