代码

代码里有TextTimerController 这一种例用方法较怪，Text ,Button Datepicker 的使用。
import router from '@ohos.router’则是引入路由模块。

import router from '@ohos.router'
@Entry
@Component
struct TextnewClock {
  textTimerController: TextTimerController = new TextTimerController()
  @State format: string = 'mm:ss.SS'
  @State value: string =''
  @State isLunar: boolean = false
  private selectedDate: Date = new Date('2021-08-08')
  @State getDate:string=""
  build() {
    Column() {


      TextTimer({ isCountDown: true, count: 30000, controller: this.textTimerController })
        .format(this.format)
        .fontColor(Color.Black)
        .fontSize(50)
        .onTimer((utc: number, elapsedTime: number) => {
          this.value=elapsedTime.toString()
          console.info('textTimer notCountDown utc is：' + utc + ', elapsedTime: ' + elapsedTime)
        })
      Row() {
        Button("开始").onClick(() => {
          this.textTimerController.start()
        })
        Button("停止").onClick(() => {
          this.textTimerController.pause()
        })
        Button("重置").onClick(() => {
          this.textTimerController.reset()
        })

      }
      TextInput({text: this.value,placeholder:'时间'}).backgroundColor('#fff').type(InputType.Normal).onChange(value=>{

      })

      Button('跳转'+ this.value, { type: ButtonType.Capsule, stateEffect: true }).backgroundColor(0x317aff).width(200).onClick(()=>{
        router.pushUrl({
          url:"pages/TimePage",
          params:{
            params: this.value
          }
        })
      })


      TextInput({text:  this.getDate,placeholder:'时间'}).backgroundColor('#fff').type(InputType.Normal).onChange(value=>{

      })
      Button('跳转'+  this.getDate, { type: ButtonType.Capsule, stateEffect: true }).backgroundColor(0x317aff).width(200).onClick(()=>{
        router.pushUrl({
          url:"pages/TimePage",
          params:{
            params: this.getDate
          }
        })
      })
      DatePicker({
        start: new Date('1970-1-1'),
        end: new Date('2100-1-1'),
        selected: this.selectedDate
      })
        .lunar(this.isLunar)
        .onChange((value: DatePickerResult) => {
          this.selectedDate.setFullYear(value.year, value.month, value.day)
          console.info('select current date is: ' + JSON.stringify(value))
          this.getDate= value.year.toString()+"-"+ value.month.toString()+"-"+value.day.toString()
        })
    }.justifyContent(FlexAlign.Center).width('100%').height('100%')
  }
}

跳转的页TimePage， private content:string =router.getParams()?.[“params”]这一段是获取传过来的参数。

import router from '@ohos.router'
@Entry
@Component
struct TimePage {

  private  content:string =router.getParams()?.["params"]
  build() {
    Row() {
      Column() {
        Text(this.content)
          .fontSize(50)
          .fontWeight(FontWeight.Bold)
      }
      .width('100%')
    }
    .height('100%')
  }
}
