Ionic 2：popToRoot（）不会重定向到根组件（主页） [英] Ionic 2 : popToRoot() doesn't redirect to root component ( home page )

问题描述

此功能中的每件事都可以正常工作，但 this.nav.popToRoot（）在该位置无法正常工作。
如果我将它移动到函数的开头，它可以正常工作。
没有人对此有合理的解释。

Every thing work fine in this function, but this.nav.popToRoot() doesn't work in that location. If I move it to the beginning of the function it works correctly. Doesn't any one has a logical explanation for this.

提前感谢您的时间和考虑。

Thank you in advance for your time and consideration.

以下是booking.ts组件中的代码：

Here is the code in a booking.ts component:

book(){
  let newReservation = {
    _id: this.room._id,
    from: this.details.from.substring(0,10),
    to: this.details.to.substring(0,10)
  }

  let loading = this.loadingCtrl.create({
    content: "Booking room..."
  });

  loading.present();

  this.roomsService.reserveRoom(newReservation).then((res) => {
    loading.dismiss();
    console.log("Room reserved successfully ... ");
    this.nav.popToRoot();
  }, (err) => {
    console.log(err);
  });
}

推荐答案

对我来说也是如此，但我设法替换整个历史堆栈，在我的情况下，我不需要保留历史堆栈，这就是我做的方式：

It happens the same to me, but i managed to replace the whole history stack, in my case after a certain point i don't need to keep the history stack, this is how i did it:

this.navCtrl.setPages([
  { page: RootPageHere }
]);

在promise中运行。

Works inside of a promise then function.
