Nav is a standalone component for loading arbitrary components and pushing new components on to the stack.
Unlike Router Outlet, Nav is not tied to a particular router. This means that if we load a Nav component, and push other components to the stack, they will not affect the app's overall router. For example, you should not push a new component to ion-nav and expect the URL to update. This fits use cases where you could have a modal, which needs its own sub-navigation, without making it tied to the apps URL.
ion-nav is not meant to be used for routing. Instead, see the routing guides for Angular, React, and Vue, or ion-router for vanilla JavaScript projects.
NavLink is a simplified API when interacting with Nav. Developers can customize the component, pass along component properties, modify the direction of the route animation or define a custom animation when navigating.
Modal can use Nav to offer a linear navigation that is independent of the URL.
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.
While not required, this interface can be used in place of the CustomEvent interface for stronger typing with Ionic events emitted from this component.
interface NavCustomEvent extends CustomEvent {
target: HTMLIonNavElement;
}
| Description | If true, the nav should animate the transition of components. |
| Attribute | animated |
| Type | boolean |
| Default | true |
| Description | By default ion-nav animates transition between pages based in the mode (ios or material design). However, this property allows to create custom transition using AnimationBuilder functions. |
| Attribute | undefined |
| Type | ((baseEl: any, opts?: any) => Animation) ｜ undefined |
| Default | undefined |
| Description | Root NavComponent to load |
| Attribute | root |
| Type | Function ｜ HTMLElement ｜ ViewController ｜ null ｜ string ｜ undefined |
| Default | undefined |
| Description | Any parameters for the root component |
| Attribute | undefined |
| Type | undefined ｜ { [key: string]: any; } |
| Default | undefined |
| Description | If the nav component should allow for swipe-to-go-back. |
| Attribute | swipe-gesture |
| Type | boolean ｜ undefined |
| Default | undefined |
| Name | Description | Bubbles |
|---|
ionNavDidChange | Event fired when the nav has changed components | false |
ionNavWillChange | Event fired when the nav will change components | false |
| Description | Returns true if the current view can go back. |
| Signature | canGoBack(view?: ViewController) => Promise<boolean> |
| Description | Get the active view. |
| Signature | getActive() => Promise<ViewController ｜ undefined> |
| Description | Get the view at the specified index. |
| Signature | getByIndex(index: number) => Promise<ViewController ｜ undefined> |
| Description | Returns the number of views in the stack. |
| Signature | getLength() => Promise<number> |
| Description | Get the previous view. |
| Signature | getPrevious(view?: ViewController) => Promise<ViewController ｜ undefined> |
| 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> |
| Description | Pop a component off of the navigation stack. Navigates back from the current component. |
| Signature | pop(opts?: NavOptions ｜ null, done?: TransitionDoneFn) => Promise<boolean> |
| Description | Pop to a specific index in the navigation stack. |
| Signature | popTo(indexOrViewCtrl: number ｜ ViewController, opts?: NavOptions ｜ null, done?: TransitionDoneFn) => Promise<boolean> |
| 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> |
| 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> |
| 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> |
| 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> |
