如图中点击跳转到详情页，url中的type值怎么传？

<segment-carpool items="{{items}}" result="{{result}}" resultthree="{{result3}}" resultfous="{{result4}}"
 binditemchengde="onItemChengdeEvent" defaultIndex="0">
  <view slot="0" class="segment-page wehicle-page">
  </view>
  <view slot="1" class="segment-page people-page">
    <view wx:if="{{isQuerying == true}}">
      <view class="comment-title">全部信息（共有{{result1}}条）</view>
      <sumlistone wx:for="{{listones}}" wx:key="key" wx:for-item="listone" list1="{{listone}}"></sumlistone>
    </view>
    <view wx:else>
      <view class="comment-title">全部信息（共有{{result1}}条）</view>
      <wehicle wx:for="{{listones}}" wx:key="key" wx:for-item="listone" list1="{{listone}}" items="items.item" 
             detailurl="../detail/detail?type={{itemchengde.items}}&index={{index}}"></wehicle>
    </view>
  </view>
  <view slot="2" class="segment-page train-page">

  <view slot="4" class="segment-page money-page">

</segment-carpool>
<loadingmore hasmore="{{hasmore}}"></loadingmore>

JS代码

data: {
    items: ["全部", "我要找车", "我要找人", "我找货车", "我要找货"],
  },
 onItemChengdeEvent(event) {
    console.log(event)
    const that = this;
    var index = event.detail.index;
    that.setData({
      index:index
    })
  },
