HarmonyOS 鸿蒙Next 是否支持一个Component从一个父容器组件中移除然后加载到另一个父容器组件

您的需要可以这么实现：在A页面跳转到B页面时，记录视频播放时间time，通过router的params传参数到B页面，再获取time，视频播放的时候，直接设置从time开始播放，相关代码如下：

A页面：
[@Entry](/user/Entry)
[@Component](/user/Component)
struct Index {
 [@State](/user/State) message: string = 'Hello World';
 public videoController:VideoController =new VideoController();
 private time:number = 0;
 build() {
   Row() {
     Column() {
       Text(this.message)
         .fontSize(50)
         .fontWeight(FontWeight.Bold)
       Video({src:videoPath),controller:this.videoController}).height(200).autoPlay(true).onUpdate((event)=>{
         this.time =event.time;
       })
       Button("跳转").onClick(()=>{
         router.pushUrl({url:"pages/index2",params:{time:this.time}})
       }).height(100).width(200)
     }
     .width('100%')
   }
   .height('100%')
 }
}
B页面：
import { router } from '[@kit](/user/kit).ArkUI';
[@Entry](/user/Entry)
[@Component](/user/Component)
struct Index2 {
 [@State](/user/State) message: string = 'Hello World';
 public videoController:VideoController =new VideoController();
 private time?:number = 0;
 build() {
   Row() {
     Column() {
       Text(this.message)
         .fontSize(50)
         .fontWeight(FontWeight.Bold)
       if(this.time){
         Video({src:videoPath,controller:this.videoController}).height(200).autoPlay(true).onPrepared(()=>{
           this.videoController.setCurrentTime(this.time)
         });
       }
     }
     .width('100%')
   }
   .height('100%')
 }
 aboutToAppear(): void {
   let param = router.getParams() as Record<string,number>;
   this.time = param['time'];
 }
}
