ion-nav
Navは、任意のコンポーネントをロードし、スタックに新しいコンポーネントを追加するためのスタンドアロンコンポーネントです。
Router Outletとは異なり、Navは特定のルーターに縛られることはありません。つまり、Navコンポーネントをロードし、他のコンポーネントをスタックにプッシュしても、アプリ全体のルーターには影響しない。例えば、新しいコンポーネントをion-navにプッシュして、URLが更新されることを期待するべきではありません。これは、アプリのURLに関連付けずに、独自のサブナビゲーションが必要なモーダルがあるような使用例に適しています。
注記
ion-navはルーティングに使用するものではありません。 代わりに、Angular、React、Vue、またはバニラJavaScriptプロジェクト用のion-routerのルーティングガイドを参照してください。
NavLinkを利用する
NavLinkは、Navと対話する際の簡略化されたAPIです。開発者は、コンポーネントをカスタマイズしたり、コンポーネントのプロパティを渡したり、ルートアニメーションの方向を変更したり、ナビゲート時のカスタムアニメーションを定義したりすることができます。
Interfaces
NavCustomEvent
必須ではありませんが、このコンポーネントから発行される Ionic イベントでより強く型付けを行うために、CustomEvent インターフェースの代わりにこのインターフェースを使用することが可能です。
interface NavCustomEvent extends CustomEvent {
target: HTMLIonNavElement;
}

イベント
| Name | Description |
|---|---|
ionNavDidChange | Event fired when the nav has changed components |
ionNavWillChange | Event fired when the nav will change components |
メソッド
canGoBack
| Description | Returns true if the current view can go back. |
| Signature | canGoBack(view?: ViewController) => Promise<boolean> |
getActive
| Description | Get the active view. |
| Signature | getActive() => Promise<ViewController ｜ undefined> |
getByIndex
| Description | Get the view at the specified index. |
| Signature | getByIndex(index: number) => Promise<ViewController ｜ undefined> |
getPrevious
| Description | Get the previous view. |
| Signature | getPrevious(view?: ViewController) => Promise<ViewController ｜ undefined> |
insert
| Description | Inserts a component into the navigation stack at the specified index. This is useful to add a component at any point in the navigation stack. |
| Signature | insert<T extends NavComponent>(insertIndex: number, component: T, componentProps?: ComponentProps<T> ｜ null, opts?: NavOptions ｜ null, done?: TransitionDoneFn) => Promise<boolean> |
insertPages
| Description | Inserts an array of components into the navigation stack at the specified index. The last component in the array will become instantiated as a view, and animate in to become the active view. |
| Signature | insertPages(insertIndex: number, insertComponents: NavComponent[] ｜ NavComponentWithProps[], opts?: NavOptions ｜ null, done?: TransitionDoneFn) => Promise<boolean> |
pop
| Description | Pop a component off of the navigation stack. Navigates back from the current component. |
| Signature | pop(opts?: NavOptions ｜ null, done?: TransitionDoneFn) => Promise<boolean> |
popTo
| Description | Pop to a specific index in the navigation stack. |
| Signature | popTo(indexOrViewCtrl: number ｜ ViewController, opts?: NavOptions ｜ null, done?: TransitionDoneFn) => Promise<boolean> |
popToRoot
| Description | Navigate back to the root of the stack, no matter how far back that is. |
| Signature | popToRoot(opts?: NavOptions ｜ null, done?: TransitionDoneFn) => Promise<boolean> |
push
| Description | Push a new component onto the current navigation stack. Pass any additional information along as an object. This additional information is accessible through NavParams. |
| Signature | push<T extends NavComponent>(component: T, componentProps?: ComponentProps<T> ｜ null, opts?: NavOptions ｜ null, done?: TransitionDoneFn) => Promise<boolean> |
removeIndex
| Description | Removes a component from the navigation stack at the specified index. |
| Signature | removeIndex(startIndex: number, removeCount?: number, opts?: NavOptions ｜ null, done?: TransitionDoneFn) => Promise<boolean> |
setPages
| Description | Set the views of the current navigation stack and navigate to the last view. By default animations are disabled, but they can be enabled by passing options to the navigation controller. Navigation parameters can also be passed to the individual pages in the array. |
| Signature | setPages(views: NavComponent[] ｜ NavComponentWithProps[], opts?: NavOptions ｜ null, done?: TransitionDoneFn) => Promise<boolean> |
setRoot
| Description | Set the root for the current navigation stack to a component. |
| Signature | setRoot<T extends NavComponent>(component: T, componentProps?: ComponentProps<T> ｜ null, opts?: NavOptions ｜ null, done?: TransitionDoneFn) => Promise<boolean> |
