Ionic 2 Angular NavController，弹回倒数第二页 [英] Ionic 2 Angular NavController, pop back to second last page

问题描述

我有以下导航案例:

Home -> navCtrl.push(SearchPage) -> navCtrl.push(ResultPage)

或

Home -> navCtrl.push(SearchPage) -> navCtrl.push(ResultPage) -> navCtrl.push(DetailPage)

我想导航回 SearchPage.在第一种情况下，没有问题，我可以使用

I want to navigate back to SearchPage. In first case, there is no problem, I can use

this.navCtrl.pop()

但是，在第二种情况下，我尝试使用

But, in second case, I try to use

this.navCtrl.popTo(SearchPage)

这并没有按预期工作.Ionic 只在堆栈中导航一页.我知道 popTo() 存在问题(https://github.com/driftyco/ionic/issues/6513)

and this does not work as expected. Ionic navigates only one page back in stack. I know there is an issue with popTo() (https://github.com/driftyco/ionic/issues/6513)

我该如何解决这个问题?

How can I solve this problem?

推荐答案

好的，找到了解决方案.看起来它有效......至少目前是这样

ok, found a solution. It looks like it works ... at least for the moment

this.navCtrl
        .push(SearchPage)
        .then(() => {

            const index = this.viewCtrl.index;

            for(let i = index; i > 0; i--){
                this.navCtrl.remove(i);
            }

        });
