详解Angular路由动画及高阶动画函数

一、路由动画

路由动画需要在host元数据中指定触发器。动画注意不要过多，否则适得其反。

内容优先，引导用户去注意到某个内容。动画只是辅助手段。

在router.animate.ts中定义一个进场动画，一个离场动画。

因为进场动画和离场动画用的特别频繁，有一个别名叫:enter和:leave。

import { trigger, state, transition, style, animate} from '@angular/animations';

export const slideToRight = trigger('routeAnim',[
    state('void',style({'position':'fixed','width':'100%','height':'100%'})),
    state('*',style({'position':'fixed','width':'100%','height':'80%'})),
    transition('void => *',[
        style({transform:'translateX(-100%)'}),
        animate('.5s ease-in-out', style({transform:'translateX(0)'}))
    ]),
    transition('* => void',[
        style({transform:'translateX(0)'}),
        animate('.5s ease-in-out', style({transform:'translateX(100%)'}))
    ]),
]);

在project-list中使用路由动画。

import { Component, OnInit , HostBinding } from "@angular/core";
import { MatDialog } from "@angular/material";
import { NewProjectComponent } from "../new-project/new-project.component";
import { InviteComponent } from '../invite/invite.component';
import { ConfirmDialogComponent } from '../../shared/confirm-dialog/confirm-dialog.component';
import {slideToRight} from '../../animate/router.animate'

@Component({
  selector: "app-project-list",
  templateUrl: "./project-list.component.html",
  styleUrls: ["./project-list.component.scss"],
  animations:[
    slideToRight
  ]
})
export class ProjectListComponent implements OnInit {
  @HostBinding('@routeAnim') state;

  projects = [
    {
      name: "企业协作平台",
      desc: "这是一个企业内部项目",
      coverImg: "assets/images/covers/0.jpg"
    },
    {
      name: "自动化测试项目",
      desc: "这是一个企业内部项目",
      coverImg: "assets/images/covers/2.jpg"
    }
  ];
  constructor(private dialog: MatDialog) { }

  ngOnInit() { }

  openNewProjectDialog() {
    // this.dialog.open(NewProjectComponent,{data:'this is a dialog'});
    const dialogRef = this.dialog.open(NewProjectComponent, {
      data: { title: '新建项目' }
    });
    dialogRef.afterClosed().subscribe((result) => {
      console.log(result);
    });
  }

  lauchInviteDialog() {
    const dialogRef = this.dialog.open(InviteComponent);
  }

  lauchUpdateDialog() {
    const dialogRef = this.dialog.open(NewProjectComponent, {
      data: { title: '编辑项目' }
    });
  }

  lauchConfimDialog() {
    const dialogRef = this.dialog.open(ConfirmDialogComponent, {
      data: { title: '编辑项目', content: '您确认删除该项目吗？' }
    });
  }
}

在task-home中使用路由动画。

import { Component, OnInit , HostBinding } from "@angular/core";
import { NewTaskComponent } from "../new-task/new-task.component";
import { MatDialog } from "@angular/material";
import { CopyTaskComponent } from "../copy-task/copy-task.component";
import { ConfirmDialogComponent } from "../../shared/confirm-dialog/confirm-dialog.component";
import { NewTaskListComponent } from "../new-task-list/new-task-list.component";
import {slideToRight} from '../../animate/router.animate';

@Component({
  selector: "app-task-home",
  templateUrl: "./task-home.component.html",
  styleUrls: ["./task-home.component.scss"],
  animations:[
    slideToRight
  ]
})
export class TaskHomeComponent implements OnInit {
  constructor(private dialog: MatDialog) {}

  @HostBinding('@routeAnim') state;
  ngOnInit() {}

  launchNewTaskDialog() {
    // this.dialog.open(NewTaskComponent);
    const dialogRef = this.dialog.open(NewTaskComponent, {
      data: { title: "新建任务" }
    });
  }
  lauchCopyTaskDialog() {
    const dialogRef = this.dialog.open(CopyTaskComponent, {
      data: { lists: this.lists }
    });
  }

  launchUpdateTaskDialog(task) {
    const dialogRef = this.dialog.open(NewTaskComponent, {
      data: { title: "修改任务", task: task }
    });
  }

  launchConfirmDialog() {
    const dialogRef = this.dialog.open(ConfirmDialogComponent, {
      data: { title: "删除任务列表", content: "您确定要删除该任务列表吗？" }
    });
  }

  launchEditListDialog() {
    const dialogRef = this.dialog.open(NewTaskListComponent, {
      data: { title: "更改列表名称" }
    });
    dialogRef.afterClosed().subscribe(result => console.log(result));
  }
  launchNewListDialog() {
    const dialogRef = this.dialog.open(NewTaskListComponent, {
      data: { title: "新建列表名称" }
    });
    dialogRef.afterClosed().subscribe(result => console.log(result));
  }
  lists = [
    {
      id: 1,
      name: "待办",
      tasks: [
        {
          id: 1,
          desc: "任务一： 去星巴克买咖啡",
          completed: true,
          priority: 3,
          owner: {
            id: 1,
            name: "张三",
            avatar: "avatars:svg-11"
          },
          dueDate: new Date(),
          reminder: new Date()
        },
        {
          id: 2,
          desc: "任务一： 完成老板布置的PPT作BТt&r7FFSРТ
