ionic v2中新的周期函数
| Page Event | Description |
|---|---|
ionViewLoaded |
Runs when the page has loaded. This event only happens once per page being created and added to the DOM. If a page leaves but is cached, then this event will not fire again on a subsequent viewing. The ionViewLoaded event is good place to put your setup code for the page. |
ionViewWillEnter |
Runs when the page is about to enter and become the active page. |
ionViewDidEnter |
Runs when the page has fully entered and is now the active page. This event will fire, whether it was the first load or a cached page. |
ionViewWillLeave |
Runs when the page is about to leave and no longer be the active page. |
ionViewDidLeave |
Runs when the page has finished leaving and is no longer the active page. |
ionViewWillUnload |
Runs when the page is about to be destroyed and have its elements removed. |
ionViewDidUnload |
Runs after the page has been destroyed and its elements have been removed. |
