       @Entry
       
       
@Component
       
       
struct Index {
       
       
  @State message: string = 'Hello World'
       
       

       
       
  build() {
       
       
    Row() {
       
       
      Column() {
       
       
        Text(this.message)
       
       
          .fontSize(50)
       
       
          .fontWeight(FontWeight.Bold).onClick(()=>{
       
       
          let date = new Date()
       
       

       
       
//获取当前时间
       
       
//          this.message=date.toLocaleString();
       
       
          //周几
       
       
//          this.message=date.getUTCDay().toString();
       
       

       
       
//日期
       
       
//          this.message=date.getUTCDate().toString();
       
       
//          //农历月份
       
       
//          this.message=date.getUTCMonth().toString();
       
       

       
       

       
       
          this.message=date.getFullYear() + "年" + (date.getMonth() + 1) + "月" + date.getDate() + "日" + date.getHours() + "时" + date.getMinutes() + "分" + date.getSeconds()+ "秒"
       
       

       
       

       
       
        })
       
       
      }
       
       
      .width('100%')
       
       
    }
       
       
    .height('100%')
       
       
  }
       
       
}
