直接看代码:
一、WXML代码示例:
< view > < !--左侧栏--> < scroll-view class=\'scroll_left\' scroll-y="true"> < view > < block wx:for="{{list}}" wx:for-index="idx" wx:for-item="itemName" wx:key="*this"> < !--当前项的id等于item项的id,那个就是当前状态--> < !--用data-index记录这个数据在数组的下标位置,使用data-id设置每个item的id值,供打开右侧侧滑栏使用--> < viewbindtap="switchRightTab" data-index="{{index}}" data- > {{itemName[0].name}}< /view> < /block> < /view> < /scroll-view> < !--右侧栏--> < !--如果使用 scroll-into-view 属性,必须设置 scroll-view 的高度,且最好是动态获取屏幕高度 --> < !-- scroll-into-view 属性 值应为某子元素id(id不能以数字开头)。设置哪个方向可滚动,则在哪个方向滚动到该元素 --> < scroll-view scroll-y="true"style="height:{{winHeight}}px; " scroll-into-view="{{scrollTopId}}" scroll-with-animation="true"> < view > < view class=\'mink\' wx:for="{{list}}" wx:for-index="idx" wx:for-item="itemName" wx:key="*this" bindscroll="scrollTop"> < view class=\'minl\' id=\'{{idx}}\'> {{itemName[0].name}}< /view> < block wx:for="{{itemName}}" wx:for-index="idex" wx:key="*this" > < viewwx:if="{{idex> 0}}"> < navigator url="../detail/detail" hover-> < view> < image src="https://www.songbingjia.com/android/{{item.picture}}"> < /image> < view > < text> {{item.desc}}< /text> < /view> < /view> < /navigator> < /view> < /block> < /view> < view style="width:100%; height:30rpx; background:#f0f4f7"> < /view> < /view> < /scroll-view> < /view>

二、.JS代码示例
var list = { "List": [ { \'A\': [ { name: \'测试1\' }, { \'picture\': \'../images/t1.png\', \'desc\': \'测试1-1\' }, { \'picture\': \'../images/t2.png\', \'desc\': \'测试1-2\' }, { \'picture\': \'../images/t3.png\', \'desc\': \'测试1-3\' }, { \'picture\': \'../images/t1.png\', \'desc\': \'测试1-4\' } ], \'B\': [ { name: \'测试2\' }, { \'picture\': \'../images/t1.png\', \'desc\': \'测试2-1\' }, { \'picture\': \'../images/t2.png\', \'desc\': \'测试2-1\' }, { \'picture\': \'../images/t3.png\', \'desc\': \'测试2-3\' }, { \'picture\': \'../images/t1.png\', \'desc\': \'测试2-4\' } ], \'C\': [ { name: \'测试3\' }, { \'picture\': \'../images/t1.png\', \'desc\': \'测试3-1\' }, { \'picture\': \'../images/t2.png\', \'desc\': \'测试3-2\' }, { \'picture\': \'../images/t3.png\', \'desc\': \'测试3-3\' }, { \'picture\': \'../images/t1.png\', \'desc\': \'测试3-4\' } ], \'D\': [ { name: \'测试4\' }, { \'picture\': \'../images/t1.png\', \'desc\': \'测试4-1\' }, { \'picture\': \'../images/t2.png\', \'desc\': \'测试4-2\' }, { \'picture\': \'.../images/t3.png\', \'desc\': \'测试4-3\'}, { \'picture\': \'../images/t1.png\', \'desc\': \'测试4-4\'} ], \'E\': [ { name: \'测试5\' }, { \'picture\': \'../images/t1.png\', \'desc\': \'测试5-1\' }, { \'picture\': \'../images/t2.png\', \'desc\': \'测试5-2\' }, { \'picture\': \'../images/t3.png\', \'desc\': \'测试5-3\' }, { \'picture\': \'../images/t1.png\', \'desc\': \'测试5-4\' } ], \'F\': [ { name: \'测试6\' }, { \'picture\': \'../images/t1.png\', \'desc\': \'测试6-1\' }, { \'picture\': \'../images/t2.png\', \'desc\': \'测试6-2\' }, { \'picture\': \'../images/t3.png\', \'desc\': \'测试6-3\' }, { \'picture\': \'../images/t1.png\', \'desc\': \'测试6-4\' } ], \'G\': [ { name: \'测试7\' }, { \'picture\': \'../images/t1.png\', \'desc\': \'测试7-1\' }, { \'picture\': \'../images/t2.png\', \'desc\': \'测试7-2\' }, { \'picture\': \'../images/t3.png\', \'desc\': \'测试7-3\' }, { \'picture\': \'../images/t1.png\', \'desc\': \'测试7-4\' } ], } ], } module.exports = list; Page({ data: { // 左侧点击类样式 curNav: \'A\', }, onReady: function () { // 生命周期函数--监听页面初次渲染完成 var listChild1 = list.List[0]; var that = this; // 获取可视区高度 wx.getSystemInfo({ success: function (res) { that.setData({ list: listChild1, winHeight: res.windowHeight, }) } }) }, //点击左侧 tab ,右侧列表相应位置联动 置顶 switchRightTab: function (e) { var id = e.target.id; console.log(typeof id) this.setData({ // 动态把获取到的 id 传给 scrollTopId scrollTopId: id, // 左侧点击类样式 curNav:id }) } })
