没有把数组值全部替换，是不断将数据追加push进数组。 基础库版本：2.10.3 const updateList = `tabs[${activeTab}].list[${page}]` const updatePage = `tabs[${activeTab}].page` this.setData({ [updateList]: res, [updatePage]: page + 1 }) <!-- 这是自定义组件的内部WXML结构 --> <scroll-view class="tab-content" enable-back-to-top="{{true}}" scroll-y="{{true}}" scroll-anchoring="{{true}}" lower-threshold="100" bindscrolltolower="updateGameList"> <view class="game-card-wrap" wx:for="{{gameListWrap}}" wx:for-item="gameList" wx:for-index="gameListIdx" wx:key="gameListIdx"> <view class="game-card" hover-class="hover-class" hover-start-time="100" wx:for="{{gameList}}" wx:for-item="game" wx:for-index="gameIdx" wx:key="gid"> </view> </view> </scroll-view>
