<! -- Navigation scroll --> <scroll-view class = "tui-city-scroll" scroll-x = "true" scroll-into-view = "NAV {status}" scroll -with-animation = "true"> <text bindtap = "getStatus" id = "NAV {index}" class = "tui-nav-li {index = status? 'Tui-nav-active': ''}" data-index = "{index}" wx: for = "{navList }}" >{{ item }}</text> </scroll-view> <! -- List scroll area --> <view class = "tui-fixed-y"> <scroll-view class = "tui-city-scroll-y" scroll-y = "true" scroll-into-view = "NAV {status}" scroll-with-animation = "true"> <view wx: for = "{navList}"> <view id = "NAV {index}" class = "tui-list-head" >{{ item }}</view> <view class = "tui-list-li" >{{ item }}list {{ index }}</view> </scroll-view> </ view>


.tui-fixed-x{ width: 100%; position: fixed; top: 0; left: 0;}.tui-city-scroll{ height: 80rpx; line-height: 80rpx; width: 100%; white-space: nowrap;}.tui-nav-li{ font-size: 30rpx; padding: 0 8rpx;}.tui-nav-li:first-child{padding-left: 16rpx;}.tui-nav-li:last-child{padding-right: 16rpx;}.tui-nav-active{color: red;}.tui-fixed-y{ width: 100%; height: calc(100% - 80rpx); position: fixed; bottom: 0; left: 0;}.tui-city-scroll-y{ padding: 0 20rpx; height: 100%; box-sizing: border-box;}.tui-list-head{ height: 50px; line-height: 50px; text-align: center; font-size: 30rpx; color: blue;}.tui-list-li{ height: 400px; padding: 10rpx; color: #fff; font-size: 50rpx; background-color: lightgreen;}
