建立对应关系就好了。或者用 data-* 传递markerId
<view catchtap="clickme" data-index="{{渲染视图用的数组下标}}">clickme: function(e) {var index = e.currentTarget.dataset.index;this.setData({showText: this.data.markers[index].markerId;})}<map latitude="{{lat}}" longitude="{{lon}}" markers='{{markers}}' bindmarkertap="clickme" enable-3D="true" id="{{item.markerId}}"></map>
clickme:function(e){var index = e.currentTarget.dataset.index;this.setData({showText: this.data.markers[index].markerId,})this.showModal();},<text>2022年7月29日~8月2日 | 成都 </text><map latitude="{{lat}}" longitude="{{lon}}" markers='{{markers}}' bindmarkertap="clickme" enable-3D="true"></map><view animation="{{animationData}}" class="commodity_attr_box" wx:if="{{showModalStatus}}" ><view class="tips">请左右滑动下面切换美食点↓↓↓</view>这是第{{data-markerId}}个点</view></view>
