Default Value

Mandatory

Description

slide

SlideEffect

Right

No

Slide effect during page transition. For details about the valid values, see the description of SlideEffect.

translate

{

x? : number,

y? : number,

z? : number

}

-

No

Translation effect during page transition, which is the value of the start point of entrance and the end point of exit. When this parameter is set together with slide, the latter takes effect by default.

No

Opacity, which is the opacity value of the start point of entrance or the end point of exit.
- SlideEffect enums

Name

Description

Left

When set to Enter, slides in from the left. When set to Exit, slides out to the left.

Right

When set to Enter, slides in from the right. When set to Exit, slides out to the right.

Top

When set to Enter, slides in from the top. When set to Exit, slides out to the top.

## Events The PageTransitionEnter and PageTransitionExit components support the following events:

Event

Description

onEnter(type: RouteType, progress: number) => void

The callback input parameter is the normalized progress of the current entrance animation. The value range is 0–1.

onExit(type: RouteType, progress: number) => void

The callback input parameter is the normalized progress of the current exit animation. The value range is 0–1.
## Example Customization method 1: The entrance animation of the current page is configured as fade-in, and the exit animation is configured as zoom-out. ``` // index.ets @Entry @Component struct PageTransitionExample1 { @State scale: number = 1 @State opacity: number = 1 @State active: boolean = false build() { Column() { Navigator({ target: 'pages/page1', type: NavigationType.Push }) { Image($r('app.media.bg1')).width("100%").height("100%") } .onClick(() => { this.active = true }) }.scale({ x: this.scale }).opacity(this.opacity) } // Customization method 1: Customize the transition process. pageTransition() { PageTransitionEnter({ duration: 1200, curve: Curve.Linear }) .onEnter((type: RouteType, progress: number) => { this.scale = 1 this.opacity = progress }) // The onEnter callback is triggered frame by frame during the entrance process. The input parameter is the normalized progress of the animation (0% to 100%). PageTransitionExit({ duration: 1500, curve: Curve.Ease }) .onExit((type: RouteType, progress: number) => { this.scale = 1 - progress this.opacity = 1 }) // The onExit callback is triggered frame by frame during the exit process. The input parameter is the normalized progress of the animation (0% to 100%). } } ``` ``` // page1.ets @Entry @Component struct AExample { @State scale: number = 1 @State opacity: number = 1 @State active: boolean = false build() { Column() { Navigator({ target: 'pages/index' ,type: NavigationType.Push}) { Image($r('app.media.bg2')).width("100%").height("100%") } }.height("100%").width("100%").scale({ x: this.scale }).opacity(this.opacity) } // Customization method 1: Customize the transition process. pageTransition() { PageTransitionEnter({ duration: 1200, curve: Curve.Linear }) .onEnter((type: RouteType, progress: number) => { this.scale = 1 this.opacity = progress }) // The onEnter callback is triggered frame by frame during the entrance process. The input parameter is the normalized progress of the animation (0% to 100%). PageTransitionExit({ duration: 1500, curve: Curve.Ease }) .onExit((type: RouteType, progress: number) => { this.scale = 1 - progress this.opacity = 1 }) // The onExit callback is triggered frame by frame during the exi process. The input parameter is the normalized progress of the animation (0% to 100%). } } ``` ![](figures/pagetransition1.gif) Customization method 2: The entrance animation of the current page is configured to slide in from the left, and the exit animation is configured to zoom out with opacity change. ``` // index.ets @Entry @Component struct PageTransitionExample { @State scale: number = 1 @State opacity: number = 1 @State active: boolean = false build() { Column() { Navigator({ target: 'pages/page1', type: NavigationType.Push }) { Image($r('app.media.bg1')).width("100%").height("100%") } .onClick(() => { this.active = true }) }.scale({ x: this.scale }).opacity(this.opacity) } // Customization method 2: Use the default effects provided by the system, such as translation, scaling, and opacity. pageTransition() { PageTransitionEnter({ duration: 1200 }) .slide(SlideEffect.Left) PageTransitionExit({ delay: 100 }) .translate({ x: 100.0, y: 100.0 }) .opacity(0) } } ``` ``` // page1.ets @Entry @Component struct PageTransitionExample1 { @State scale: number = 1 @State opacity: number = 1 @State active: boolean = false build() { Column() { Navigator({ target: 'pages/index', type: NavigationType.Push }) { Image($r('app.media.bg2')).width ("100%").height("100%") } .onClick(() => { this.active = true }) }.scale({ x: this.scale }).opacity(this.opacity) } // Customization method 2: Use the default effects provided by the system, such as translation, scaling, and opacity. pageTransition() { PageTransitionEnter({ duration: 1200 }) .slide(SlideEffect.Left) PageTransitionExit({ delay: 100 }) .translate({ x: 100.0, y: 100.0 }) .opacity(0) } } ``` ![](figures/pagetransition2.gif)
