HarmonyOs之路由简单跳转

Navigation路由相关的操作都是基于页面栈NavPathStack提供的方法进行，每个Navigation都需要创建并传入一个NavPathStack对象，用于管理页面。主要涉及页面跳转、页面返回、页面替换、页面删除、参数获取、路由拦截等功能。

@Entry
@Component
struct Index {// 创建一个页面栈对象并传入Navigation 并分发下去使子组件也能使用@Provide('pageInfos') pageInfos: NavPathStack = new NavPathStack()@BuilderPageMap(name: string) {if (name === "NavDestinationTitle1") {pageOneTmp()}}build() {Navigation(this.pageInfos) {Button('dianji').onClick((event: ClickEvent) => {console.log('dianjile')this.pageInfos.pushPath({ name: "NavDestinationTitle1", param: "PageOne Param" })})}.title('Main').titleMode(NavigationTitleMode.Full).navDestination(this.PageMap)}
}@Component
export struct pageOneTmp {@Consume('pageInfos') pageInfos: NavPathStack;build() {NavDestination() {Column() {Text("NavDestinationContent1")}.width('100%').height('100%')}.title("NavDestinationTitle1").onBackPressed(() => {const popDestinationInfo = this.pageInfos.pop() // 弹出路由栈栈顶元素console.log('pop' + '返回值' + JSON.stringify(popDestinationInfo))return true})}
}
