微信小程序，多个view绑定相同点击事件，如何绑定当前view

Question

如图所示两个栏目分别弹出不同的的从底部弹出的弹层 怎么定位当前的view对应的弹层呢

<view class='item'>
<view bindtap="showModal">已选择</view>
<view class="mask" bindtap="hideModal" wx:if="{{ModalStatus}}"></view>
<view animation="{{animationData}}" class="commodity_attr_box" wx:if="{{ModalStatus}}">
  <view class='product_info box-center-v border'>规格弹出层</view>
</view>
</view>
<view class='item'>
<view bindtap="showModal">配送至</view>
<view class="mask" bindtap="hideModal" wx:if="{{ModalStatus}}"></view>
<view animation="{{animationData}}" class="commodity_attr_box" wx:if="{{ModalStatus}}">
  <view class='product_info box-center-v border'>地址弹出层</view>
</view>
</view>

showModal: function () {
    // 显示遮罩层
    var animation = wx.createAnimation({
      duration:300,
      timingFunction: "ease",
      delay: 0,
    })
    this.animation = animation
    animation.translateY(600).step()
    this.setData({
      animationData: animation.export(),
      ModalStatus: true
    })
    setTimeout(function () {
      animation.translateY(0).step()
      this.setData({
        animationData: animation.export()
      })
    }.bind(this), 200)
  },
  //隐藏对话框
  hideModal: function () {
    // 隐藏遮罩层
    var animation = wx.createAnimation({
      duration: 200,
      timingFunction: "linear",
      delay: 0
    })
    this.animation = animation
    animation.translateY(400).step()
    this.setData({
      animationData: animation.export(),
    })
    setTimeout(function () {
      animation.translateY(0).step()
      this.setData({
        animationData: animation.export(),
        ModalStatus: false
      })
    }.bind(this), 200)
  }

Answer 1

可以传个值给点击事件：

<view class="mask" data-index='one' bindtap="hideModal" wx:if="{{ModalStatus}}"></view>


hideModal:(e)=>{
    let index=e.datail.index;
    ///dome somethings... 
}

你是想知道现在弹起的是哪个view吗？那你为何不设个变量，存当前弹窗的队列，最后一个就永远是最上面的，多弹窗设计下的管理方案。
