Angular动画

animation

// 使用方法
git clone https://git.oschina.net/mumu-osc/learn-component.git
cd learn-component
git pull origin animation
npm install 
ng serve

写法

// fly-in.ts
import { trigger, state, style, transition, animate, keyframes } from '@angular/animations';

export const flyIn = trigger('flyIn', [
    transition('void => *', [
        animate(3000, keyframes([
            style({ opacity: 0, transform: 'translateX(-100%)', offset: 0 }),
            style({ opacity: 1, transform: 'translateX(25px)', offset: 0.3 }),
            style({ opacity: 1, transform: 'translateX(0)', offset: 1.0 })
        ]))
    ]),
    transition('* => void', [
        animate(300, keyframes([
            style({ opacity: 1, transform: 'translateX(0)', offset: 0 }),
            style({ opacity: 1, transform: 'translateX(-25px)', offset: 0.7 }),
            style({ opacity: 0, transform: 'translateX(100%)', offset: 1.0 })
        ]))
    ])
]);

使用

<div class="panel panel-primary" [@flyIn]="state">
  <div class="panel-heading">飞入效果</div>
  <div class="panel-body">
    飞入效果
  </div>
</div>
import { Component, OnInit } from '@angular/core';
import { flyIn } from '../animations/fly-in';

@Component({
  selector: 'app-test-fly-in',
  templateUrl: './test-fly-in.component.html',
  styleUrls: ['./test-fly-in.component.css'],
  animations:[flyIn]
})
export class TestFlyInComponent implements OnInit {
  state:string;

  constructor() { }

  ngOnInit() {
  }

}

注意

需要在主模块中引入BrowserAnimationsModule

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';

import { AppComponent } from './app.component';
import { TestFlyInComponent } from './test-fly-in/test-fly-in.component';

@NgModule({
  declarations: [
    AppComponent,
    TestFlyInComponent
  ],
  imports: [
    BrowserModule,
    BrowserAnimationsModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }
