Question

我写了一个小玉石脚本

ul.sidebar-nav
  each(record in #{records})
    li
      a(href='#') #{record.sender}

我将记录数组对象传递给jade模板，但是record未定义。任何人都可以解释为什么我收到此错误？

以下是完整错误：

/home/ritesh/Sample/Sample1/Sample/views/index.jade:9 7| each(record in #{records}) 8| li > 9| a(href='#') #{record.sender} 10| Cannot read property 'sender' of undefined

TypeError: /home/ritesh/Sample/Sample1/Sample/views/index.jade:9
    7|         each(record in #{records})
    8|           li
  > 9|             a(href='#') #{record.sender}         
    10|

Answer 1

  each(record in #{records})

你不想在这里解析records;你只想将它用作数组。只需使用

  each(record in records)

它应该有用。

Answer 2

只需使用：

each record in records

无法读取Jade中未定义的属性
