ionic2 - 如何收听模态关闭事件？

Question

我需要知道我的模态何时关闭。似乎没有与ionViewDidLeave或类似方法相同的明确方法来执行此操作。我尝试过ionViewDidLeave并感觉它不适用于模式关闭，因为我没有使用navController移至该页面，而是使用模式显示页面。

home.ts

/*show modal with post form on add event page */

  postEvent(){ 

      let modal = this.modalCtrl.create(AddEvent);
      modal.present();


}

AddEvent.TS

/* Close modal and go back to feed */

     close(){

     this.viewCtrl.dismiss(); 

        //I need to change a value on the home page when this dismiss happens.  

    } 

Answer 1

您只需要在home.ts中收听模式关闭事件即可

// listen for close event after opening the modal
    postEvent(){
        let modal = this.modalCtrl.create(AddEvent);
        modal.onDidDismiss(() => {
        // Call the method to do whatever in your home.ts
           console.log('Modal closed');
    });
    modal.present();
}
