通过在Jade/Pug中循环数组来创建手风琴ID

我有一个对象数组(组件),它的每个对象都有两个属性id和消息。我想为每个对象创建手风琴,如下所示:

.alert.alert-danger(style='background-color: #ff8080; color:white; width:70%')
  #headingOne.panel-heading(role='tab', style='text-align: left')
    h4.panel-title
      a(role='button', data-toggle='collapse', data-parent='#accordion', href='#collapseOne', aria-expanded='true', aria-controls='collapseOne')
        i.more-less.glyphicon.glyphicon-plus
        |                Title
  #collapseOne.panel-collapse.collapse(role='tabpanel', aria-labelledby='headingOne')
    .panel-body Content

我得到了这个版本,但仍然不起作用。我在NodeJS服务器上得到的只是-内部错误

#accordion.panel-group(role='tablist', aria-multiselectable='true', align='center')
  each item in [1,2,3]
    .alert.alert-danger(style='background-color: #ff8080; color:white; width:70%')
      #headingOne.panel-heading(role='tab', style='text-align: left')
        h4.panel-title
          a(role='button', data-toggle='collapse', data-parent='#accordion', href='#collapse#{item}', aria-expanded='true', aria-controls='collapse#{item}')
            i.more-less.glyphicon.glyphicon-plus
            |                   Title
      div(id="collapse#{item}" class="panel-collapse collapse" role="tabpanel" aria-labelledby="headingOne")
          div(class="panel-body")
            !{item}
