HarmonyOS 鸿蒙Next 返回上级页面刷新问题

参考下：

//Index.ets

import { pageTwoTmp, Pages } from './PageTwo'

class TmpClass{
  count:number = 10
}
@Entry
@Component
struct NavigationExample {
  @Provide('pageInfo') pageInfo: NavPathStack = new NavPathStack()
  @State message: string = '做一个简单的测试'
  @Builder
  PageMap(name: string) {
    if (name === 'pageTwo') {
      pageTwoTmp({ names: name, values: this.pageInfo } as Pages)
    }
  }
  build() {
    Navigation(this.pageInfo) {
      Column() {
        Button('pushPathByName', { stateEffect: true, type: ButtonType.Capsule })
          .width('80%')
          .height(40)
          .margin(10)
          .onClick(() => {
            let tmp = new TmpClass()
            this.pageInfo.pushPathByName('pageTwo', tmp, (popInfo)=>{
              console.info("一大堆测试的数据")
              this.message = '[pushPathByName]last page is: ' + popInfo.info.name + ', result: ' + JSON.stringify(popInfo.result);
            }); // 将name指定的NavDestination页面信息入栈，传递的数据为param，添加接收处理结果的onPop回调。
          })
      }
    }.title('NavIndex').navDestination(this.PageMap)
  }
}

PageTwo.ets

export class Pages {
  names: string = ""
  values: NavPathStack | null = null
}

class resultClass {
  constructor(count: number) {
    this.count = count;
  }
  count: number = 10
}

@Builder
export function pageTwoTmp(info: Pages) {
  NavDestination() {
    Column() {
      Text("测试")
      Button('Back').onClick(() => {
        (info.values as NavPathStack).pop(new resultClass(0));
      })
    }.width('100%').height('100%')
  }.title('pageTwo')
  .onBackPressed(() => {
    (info.values as NavPathStack).pop(new resultClass(0)); // 回退到上一个页面，将处理结果传入push的onPop回调。
    return true;
  })
}

你试试这个：

this.pathStack.pop('');
