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と対話する際の簡素化された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。
Navigation within a Modal
Modal can use Nav to offer a linear navigation that is independent of the URL.
注記
The example below uses a reference to Nav and the public method APIs to push and pop views. It is recommended to use NavLink in implementations that do not require this level of granular access and control.
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;
}

| Signature | getLength() => Promise<number> |
getPrevious
| Description | Get the previous view. |
| Signature | getPrevious(view?: ViewController) => Promise<ViewController ｜ undefined> |

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> |
| Parameters | insertIndex: The index to insert the components at in the stack. insertComponents: The components to insert into the navigation stack. opts: The navigation options. done: The transition complete function. |
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> |
| Parameters | opts: The navigation options. done: The transition complete function. |
popTo
| Description | Pop to a specific index in the navigation stack. |
| Signature | popTo(indexOrViewCtrl: number ｜ ViewController, opts?: NavOptions ｜ null, done?: TransitionDoneFn) => Promise<boolean> |
| Parameters | indexOrViewCtrl: The index or view controller to pop to. opts: The navigation options. done: The transition complete function. |
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> |
| Parameters | opts: The navigation options. done: The transition complete function. |
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> |

| Signature | removeIndex(startIndex: number, removeCount?: number, opts?: NavOptions ｜ null, done?: TransitionDoneFn) => Promise<boolean> |
| Parameters | startIndex: The number to begin removal at. removeCount: The number of components to remove. opts: The navigation options. done: The transition complete function. |
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. |
