记录--左右菜单联动
这里给大家分享我在网上总结出来的一些知识,希望对大家有所帮助
对于左右菜单联动的需求是很常见的在小程序里,主要表现为:
- 点击左侧的菜单栏,右侧会切换到对应的内容区域
- 滑动右侧的内容,左侧会自动切换到对应的菜单项
主要利用的是 scroll-view标签,以及相关的一些API,可参考:uniapp.dcloud.net.cn/api/ui/node… 去获取当前的所有节点集合,再配合 scroll-view 的 scroll-top 属性,使其在点击左侧菜单栏的时候动态赋值右侧scroll-view 的 scroll-top 属性,从而实现点击左侧菜单栏时右侧内容区域进行滚动
基本UI结构:
<template> <view class="d-flex border-top border-light-secondary" style="height: 100%; box-sizing: border-box;"> <!-- 左侧菜单栏 --> <scroll-view scroll-y style="flex: 1; height: 100%;" class="border-right border-light-secondary"> <view class="border-bottom border-light-secondary py-1" hover-class="bg-light-secondary" v-for="(item,index) in cate" :key="item.id" @click="changeCate(index)"> <view class="py-1 font-md text-muted text-center" :class="activeIndex == index ? 'class-active' : ''"> {{item.name}} </view> </view> </scroll-view> <!-- 右侧数据 --> <scroll-view scroll-y style="flex: 3.5; height: 100%;"> <view class="row" v-for="(item,index) in list" :key="index"> <view class="span-8 text-center py-2" v-for="(item2,index2) in item.list" :key="index2"> <image :src="item2.src" mode="" style="width: 120upx;height: 120upx;"></image> <text class="d-block">{{item2.name}}</text> </view> </view> </scroll-view> </view> </template> <script> export default { data() { return { // 左侧菜单栏当前选中的分类 activeIndex: 0, // 左侧菜单栏分类数据 cate: [], // 右侧内容 list: [], // } }, onLoad() { // 模拟左侧菜单栏分类数据 for (let i = 0; i < 20; i++) { this.cate.push({ name: "分类" + i, id: i }) } // 模拟右侧内容数据 for (let i = 0; i < 15; i++) { this.list.push({ list: [{ src: '/static/images/demo/cate_01.png', name: '商品一' }, { src: '/static/images/demo/cate_02.png', name: '商品一' }, { src: '/static/images/demo/cate_06.png', name: '商品一' }, { src: '/static/images/demo/cate_05.png', name: '商品一' } ] }) } }, methods: { // 点击左侧菜单栏,当前选中项高亮--切换 changeCate(index) { this.activeIndex = index; }, // } } </script> <style lang="scss" scoped> .class-active { border-left: 8upx solid #FD6801; color: #FD6801 !important; } </style>
点击左侧菜单栏-右侧内容滚动到对应区域:
<template> <view class="d-flex border-top border-light-secondary" style="height: 100%; box-sizing: border-box;"> <!-- 左侧菜单栏 --> <scroll-view scroll-y style="flex: 1; height: 100%;" class="border-right border-light-secondary"> <view class="border-bottom border-light-secondary py-1 left-scroll-item" hover-class="bg-light-secondary" v-for="(item,index) in cate" :key="item.id" @click="changeCate(index)"> <view class="py-1 font-md text-muted text-center" :class="activeIndex == index ? 'class-active' : ''"> {{item.name}} </view> </view> </scroll-view> <!-- 右侧数据 --> <scroll-view scroll-y style="flex: 3.5; height: 100%;" :scroll-top="rightScrollTop" :scroll-with-animation="true"> <view class="row right-scroll-item" v-for="(item,index) in list" :key="index"> <view class="span-8 text-center py-2" v-for="(item2,index2) in item.list" :key="index2"> <image :src="item2.src" mode="" style="width: 120upx;height: 120upx;"></image> <text class="d-block">{{item2.name}}</text> </view> </view> </scroll-view> </view> </template> <script> export default { data() { return { // 左侧菜单栏当前选中的分类 activeIndex: 0, // 左侧菜单栏分类数据 cate: [], // 右侧内容 list: [], // 记录左侧导航里的每一个导航栏距离顶部的距离 leftDomsTop: [], // 记录右侧菜单距离顶部的距离 rightDomsTop: [], // 右侧内容区块滚动的距离 rightScrollTop: 0, } }, // 页面加载中类似于created--获取不到DOM节点 onLoad() { // 模拟右侧内容数据 this.getData(); }, // 页面渲染完成-可获取DOM节点,相当于mounted onReady() { const query = uni.createSelectorQuery().in(this); // 左侧导航栏中的每一个导航栏距离顶部距离 query.selectAll('.left-scroll-item').boundingClientRect(data => { this.leftDomsTop = data.map(v => v.top); }).exec(); // 右侧内容中的每一个距离顶部距离 query.selectAll('.right-scroll-item').boundingClientRect(data => { this.rightDomsTop = data.map(v => v.top); }).exec(); }, methods: { // 获取数据 getData() { // 模拟左侧菜单栏分类数据 for (let i = 0; i < 20; i++) { // 左侧导航 this.cate.push({ name: "分类" + i, id: i }) // 右侧内容 this.list.push({ list: [] }) for (let i = 0; i < this.list.length; i++) { for (let j = 0; j < 24; j++) { this.list[i].list.push({ src: '/static/images/demo/cate_01.png', name: '分类' + i + '-商品' + j }) } } } }, // 点击左侧菜单栏,当前选中项高亮--切换 changeCate(index) { this.activeIndex = index; // 右边内容scroll-view滚动到对应的区块 this.rightScrollTop = this.rightDomsTop[index]; }, // } } </script> <style lang="scss" scoped> .class-active { border-left: 8upx solid #FD6801; color: #FD6801 !important; } </style>
滚动右侧内容-左侧菜单栏跟着联动到对应菜单栏项
<template> <view class="d-flex border-top border-light-secondary" style="height: 100%; box-sizing: border-box;"> <!-- 左侧菜单栏 --> <scroll-view scroll-y style="flex: 1; height: 100%;" class="border-right border-light-secondary" id="leftScroll" :scroll-top="leftScrollTop"> <view class="border-bottom border-light-secondary py-1 left-scroll-item" hover-class="bg-light-secondary" v-for="(item,index) in cate" :key="item.id" @click="changeCate(index)"> <view class="py-1 font-md text-muted text-center" :class="activeIndex == index ?

优化
对上面的代码进行优化重构--因为有一些代码是重复使用的比如 const query = uni.createSelectorQuery().in(this);
