很香 不过也可换其他内置组件复现https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/ts-container-tabcontent-V5#%E7%A4%BA%E4%BE%8B21 NavigationEntry Component struct Index { build() { Navigation() { ​

设置模式Navigation是路由容器组件一般作为首页的根容器包括单栏(Stack)、分栏(Split)和自适应(Auto)三种显示模式.Navigation组件适用于模块内和跨模块的路由切换一次开发多端部署场景Navigation组件通过mode属性设置页面的显示模式。自适应模式下当页面宽度大于等于一定阈值( API version 9及以前520vpAPI version 10及以后600vp )时Navigation组件采用分栏模式反之采用单栏模式。将mode属性设置为NavigationMode.StackNavigation组件即可设置为单页面显示模式。toolbarConfiguration 底层标题栏.toolbarConfiguration() 里面设置的是一个数组数组里面每个元素ToolbarItem类型数据的结构如下{ value: 我的, icon:

ForEach(this.list, (item: number) { NavRouter() { // 这里是点击的内容 Column() { Text(文本 item) .width(85%) .height(60) .backgroundColor(#ccc) .borderRadius(25) .margin({ top: 10 }) .textAlign(TextAlign.Center) } ​ // 这里是跳转显示的页面 NavDestination() { Text(文本 item) .fontSize(30) .fontColor(red) }.title(标题 item) ​ }.mode(NavRouteMode.PUSH) }) }这里有一个属性mode(mode: NavRouteMode)设置指定点击NavRouter跳转到NavDestination页面时使用的路由模式PUSH_WITH_RECREATE 跳转到新的NavDestination页面时替换当前显示的NavDestination页面页面销毁但该页面信息仍保留在路由栈中。PUSH 跳转到新的NavDestination页面时覆盖当前显示的NavDestination页面该页面不销毁且页面信息保留在路由栈中。REPLACE 跳转到新的NavDestination页面时替换当前显示的NavDestination页面页面销毁且该页面信息从路由栈中清除。还有一个事件onStateChange(callback: (isActivated: boolean) void)组件激活状态切换时触发该回调。开发者点击激活NavRouter加载对应的NavDestination子组件时回调onStateChange(true)。NavRouter对应的NavDestination子组件不再显示时回调onStateChange(false)。最后效果​ Entry Component struct Index { pageStack: NavPathStack

}2、Navigation通过属性关联import Page1 from ./Page1 ​ Entry Component export struct Index { Builder PagesMap(name: string) { if (name Page1) { Page1() } } ​ build() { Navigation() { } .title(主标题) .mode(NavigationMode.Stack) .navDestination(this.PagesMap) // 通过属性的方式动态设置 } }3、控制跳转之前没有独立NavRouter 独立之后必须通过Navigation提供的页面栈管理实例来操作3.1 创建页面栈 ​ pageStack: NavPathStack new NavPathStack(); // 创建页面栈实例化对象 控制页面栈路由增删改等 3.2 注册关联 Navigation(this.pageStack) { ​ 3.3 跳转

Builder PagesMap(name: string) { if (name Test1) { Test1() } } ​ build() { Navigation(this.pageStack) { ​ Button(按钮).onClick(() { this.pageStack.pushPath({ name: Test1, param: 实际需要显示的内容 }) }) } .title(主标题) .mode(NavigationMode.Stack) .navDestination(this.PagesMap) } }Test1.etsComponent export default struct Page1 { build() { NavDestination() { Column() { Text(实际的内容) } } .title(标题) } }NavDestination的模式NavDestination的mode属性有两种值标准类型 NavDestinationMode.STANDARD标准类型的NavDestination的生命周期跟随其在NavPathStack页面栈中的位置变化而改变。弹窗类型 NavDestinationMode.DIALOG整个NavDestination默认透明显示。弹窗类型的NavDestination显示和消失时不会影响下层标准类型的NavDestination的显示和生命周期两者可以同时显示。下面处理一个弹窗问题Component export struct DialogPage { Consume pageStack: NavPathStack; param: string ​ build() { NavDestination() { Column() { Stack({ alignContent: Alignment.TopEnd }) { Text(this.param) .fontSize(30) .fontColor(red) .textAlign(TextAlign.Center) .width(100%) .margin({

param: aaa }) this.pageStack.pushPathByName(dialogPage, aaa)这两种方法都可以使用带返回回调的跳转跳转时添加onPop回调,能在页面出栈时获取返回信息this.pageStack.pushPath({ name: dialogPage, param: aaa, onPop: (popInfo) { Logger.log(popInfo.result) } })关闭退回时通过pop传回的数据Button(×).onClick(() { this.pageStack.pop(返回的内容) })页面返回// 返回到上一页 this.pageStack.pop() // 返回到上一个PageOne页面 this.pageStack.popToName(PageOne) // 返回到索引为1的页面 this.pageStack.popToIndex(1) // 返回到根首页清除栈中所有页面 this.pageStack.clear()页面替换// 将栈顶页面替换为PageOne this.pageStack.replacePath({ name: PageOne, param: PageOne Param }) this.pageStack.replacePathByName(PageOne, PageOne Param)页面删除// 删除栈中name为PageOne的所有页面 this.pageStack.removeByName(PageOne) // 删除指定索引的页面 this.pageStack.removeByIndexes([1,3,5])参数获取// 获取栈中所有页面name集合 this.pageStack.getAllPathName() // 获取索引为1的页面参数 this.pageStack.getParamByIndex(1) // 获取PageOne页面的参数 this.pageStack.getParamByName(PageOne) // 获取PageOne页面的索引集合 this.pageStack.getIndexByName(PageOne)路由拦截在页面的初始生命周期中设置aboutToAppear(): void { this.pageStack.setInterception({ willShow: (from: NavDestinationContext | NavBar, to: NavDestinationContext | NavBar, operation: NavigationOperation, isAnimated: boolean) { if (typeof to string) { return; } if (to.pathInfo.name dialogPage) { to.pathStack.pop(); to.pathStack.pushPath({ name: page1, param: bbbb }) } } }) }5 系统路由表在这里跨包的含义我们后面再讲注意这部分只能使用虚拟机运行预览器无法运行先新建一个页面PageOne//需要配置一个函数入口用于routerMap中的引用 Builder function PageOneBuilder() { PageOne(); } ​ Entry Component struct PageOne { pathStack: NavPathStack new NavPathStack() ​ build() { NavDestination() { Column() { Text(实际的内容) } } .title(PageOne) .onReady((context: NavDestinationContext) { // 跨包带来的环境中路由栈 this.pathStack context.pathStack // 获取传到当前页面中的路由传参 // let param: IData JSON.parse(this.pathStack.getParamByIndex(0) as string) as IData; let params: string[] this.pathStack.getParamByName(PageOne) as string[] // 在routerMap中配置的静态数据 Logger.log(JSON.stringify(context.getConfigInRouteMap()?.data)) }) } }新建router_map.json在main/resources/base/profile下面新建文件router_map.json文件{ routerMap: [ { name: PageOne, pageSourceFile: src/main/ets/pages/PageOne.ets, buildFunction: PageOneBuilder, data: { names: xietian } } ] }name: PageOne, 路由跳转的名字用来在页面中通过NavPathStack对象调用pushPathByName方法找到这个路由名称pageSourceFile: src/main/ets/pages/PageOne.ets, 路由跳转的实际ets文件地址buildFunction: PageOneBuilder, 跳转进入的入口函数这个函数在PageOne页面中通过Builder定义的函数data: {names: xietian}路由传入带入的静态数据可以当做Vue中Meta元数据配置模块数据在main下找到module.json5文件在module对象中添加routerMap: $profile:router_map把routerMap指向创建的router_map.json{ module: { name: entry, type: entry, description: $string:module_desc, mainElement: EntryAbility, deviceTypes: [ phone, tablet, 2in1 ], //这一句 routerMap: $profile:router_map, deliveryWithInstall: true, installationFree: false, pages: $profile:main_pages, abilities: [ { name: EntryAbility, srcEntry: ./ets/entryability/EntryAbility.ets, description: $string:EntryAbility_desc, icon: $media:layered_image, label:

action.system.home ] } ] } ] } }主文件中做路由跳转Entry Component struct Index { pageStack: NavPathStack new NavPathStack(); ​ build() { Column() { Navigation(this.pageStack) { Column() { Text(文本) .width(85%) .height(60) .backgroundColor(#ccc) .borderRadius(25) .margin({ top: 10 }) .textAlign(TextAlign.Center) .onClick(() { // 跳转的路由名为配置的路由名 // this.pageStack.pushPathByName(PageOne, null, true) this.pageStack.pushPathByName(PageOne, JSON.stringify({ a: 1, b: 2 }), true) }) } } ​ } }
