I am facing an issue with my ionic 3 page where I need to refresh the data on the page only if it is entered via a navCtrl.setRoot() and not when returned to from a navCtrl.pop(). I have been using ionViewDidEnter() to identify when the page is entered, but I am struggling to differentiate between entry methods of setRoot() and pop().
My project is built as a Tabs project, so the setRoot() function is triggered every time the tab for the page is selected.
Latest Update:
To successfully handle the back button event in Ionic, utilize Events. Override the back button functionality in your code as depicted below.
.ts
@ViewChild(Navbar) navBar: Navbar;
ionViewDidLoad() {
this.navBar.backButtonClick = (e: UIEvent) => {//override back button
this.events.publish(Handlers.NEW_PROJECT_PAGE_BUDGET_HANDLER, this.data);
this.navCtrl.pop();
}
}
Past Solution:
navCtrl.setRoot() method is used to navigate to a new page and push it onto the navigation stack. For proper implementation, utilize the constructor() of the page or
ionViewDidLoad() - This event occurs only once when the page is creatednavCtrl.pop() indicates that you can detect the action using only
ionViewDidEnter() - Executes when the page has completely loaded and becomes active. This event triggers every time the page is accessed, whether initially loaded or from cache.Looking for a way to dynamically display images based on the visibility of another image?
