$ ng g m project
功能：项目列表显示，增加，修改，删除项目。邀请其它人员加入项目。
单一性原则：希望搭建多个组件，每个组件负责自己的功能。
一、project相关组件
$ ng g c project/project-list 【项目列表组件】
$ ng g c project/project-item 【卡片组件】
$ ng g c project/new-project【新建项目组件，新建项目，或者修改项目时候会有一个对话框。】
$ ng g c project/invite 【邀请组件，邀请其它成员的对话框。】
此时这些组件都会在declarations中。
declarations: [ProjectListComponent, ProjectItemComponent, NewProjectComponent, InviteComponent],
我们希望对话框组件出现在entryComponent中。
import { NgModule } from '@angular/core';
import { SharedModule } from '../shared/shared.module';
import { ProjectListComponent } from './project-list/project-list.component';
import { ProjectItemComponent } from './project-item/project-item.component';
import { NewProjectComponent } from './new-project/new-project.component';
import { InviteComponent } from './invite/invite.component';
import { ProjectRoutingModule } from './project-routing.module';
@NgModule({
declarations: [ProjectListComponent, ProjectItemComponent, NewProjectComponent, InviteComponent],
entryComponents: [NewProjectComponent, InviteComponent],
imports: [
SharedModule,
ProjectRoutingModule
]
})
export class ProjectModule { }
二、ProjectList
循环输出每个项目的item，有一个新增项目item的快速响应的按钮。
<app-project-item *ngFor="let project of projects" [item]="project"> </app-project-item> <button mad-fab type="button" (click)="openNewProjectDialog()"> <mat-icon>add</mat-icon> </button>
project-item里的内容应该是projectList项目决定的。
export class ProjectListComponent implements OnInit { 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); } }
三、ProjectItem
应该是卡片类型的。
<mat-card class="example-card"> <mat-card-header> <mat-card-title>每日佳句</mat-card-title> </mat-card-header> <img mat-card-image [src]="item.coverImg" alt="项目封面"> <mat-card-content> {{item.desc}} </mat-card-content> <mat-card-actions> <button> <mat-icon>note</mat-icon> <span>编辑</span> </button> <button> <mat-icon>group_add</mat-icon> <span>邀请</span> </button> <button> <mat-icon>delete</mat-icon> <span>删除</span> </button> </mat-card-actions> </mat-card>
1、邀请
希望这个组件越笨越好，只显示，不做逻辑处理。
所以projectItem中点击 邀请 按钮，只负责把事件发射出去，让父组件知道，不做处理。
<button mat-button type="button" (click)="onInviteClick()">
<mat-icon>group_add</mat-icon>
<span>邀请</span>
</button>
@Output() onInvite = new EventEmitter<void>();
onInviteClick() {
this.onInvite.emit();
}
2、编辑
编辑和新建共用一套组件。
ListItem把编辑事件发射出去。
<button mat-button type="button" (click)="onEditClick()"> <mat-icon>note</mat-icon> <span>编辑</span> </button> @Output() onEdit = new EventEmitter<void>(); onEditClick() { this.onEdit.emit(); }
ProjectList得到编辑事件后lauch新建项目组件，传入title。
<app-project-item *ngFor="let project of projects" [item]="project" class="card" (onInvite)="lauchInviteDialog()" (onEdit)="lauchUpdateDialog()"> </app-project-item> lauchUpdateDialog() { const dialogRef = this.dialog.open(NewProjectComponent, { data: { title: '编辑项目' } }); }
NewProject组件中处理新建和编辑。
import { Component, OnInit, Inject } from '@angular/core'; import { MAT_DIALOG_DATA, MatDialogRef } from '@angular/material'; import { OverlayContainer } from '@angular/cdk/overlay'; @Component({ selector: 'app-new-project', templateUrl: './new-project.component.html', styleUrls: ['./new-project.component.scss'] }) export class NewProjectComponent implements OnInit { title = ''; theme: string = 'myapp-dark-theme'; constructor(@Inject(MAT_DIALOG_DATA) private data: any, public dialogRef: MatDialogRef<NewProjectComponent>, private oc: OverlayContainer) { } ngOnInit() { console.log(JSON.stringify(this.data)); this.title = this.data.title; // this.oc.themeClass = this.data.dark ? 'myapp-dark-theme' : 'null'; this.oc.getContainerElement().classList.add(this.theme); } onSave() { this.dialogRef.close('I received your message'); } }
3，删除
前面过程一样，在Project List中lauch确认对话框
<app-project-item *ngFor="let project of projects" [item]="project" class="card" (onInvite)="lauchInviteDialog()" (onEdit)="lauchUpdateDialog()" (onDelete)="lauchConfimDialog()"> </app-project-item> lauchConfimDialog() { const dialogRef = this.dialog.open(ConfirmDialogComponent, { data: { title: '编辑项目', content: '您确认删除该项目吗？' } }); }
三、路由
{ path: '', redirectTo: '/login', pathMatch: 'full' }, { path:'login',loadChildren:'./login/login.module#LoginModule' }, { path:'project',loadChildren:'./project/project.module#ProjectModule' } ];
四、NewProject
<form> <h2 md-dialog-title>新建项目</h2> <div mat-dialog-content> <mat-form-field class="example-full-width" class="full-width"> <input type="text" matInput placeholder="您的email" style="text-align: right"> </mat-form-field> <mat-form-field class="example-full-width" class="full-width"> <input type="password" matInput placeholder="您的密码" style="text-align: right"> </mat-form-field> </div> <div mat-dialog-actions> <button type="button" mat-raised-button color="primary">保存</button> <button type="button" mat-button mat-dialog-close>关闭</button> </div> </form>
五、Invite
用AutoComplete完成邀请组员的布局。
<form> <h2 md-dialog-title>邀请组员：</h2> <div mat-dialog-content> <mat-form-field class="example-full-width" class="full-width"> <input type="text" matInput placeholder="组员姓名" [matAutocomplete]="autoMembers" > <mat-autocomplete #autoMembers="matAutocomplete" [displayWith]="displayUser"> <mat-option *ngFor="let option of filteredOptions" [value]="option"> {{option.name}} </mat-option> </mat-autocomplete> </mat-form-field> </div> <div mat-dialog-actions> <button type="button" mat-raised-button color="primary" (click)="onSave()">保存</button> <button type="button" mat-button mat-dialog-close>关闭</button> </div> </form>
displayUser(user: { id: string; name: string }) { return user ? user.name : '' }
希望这个组件越笨越好，只显示，不做逻辑处理，涉及逻辑了逻辑代码会非常分散。调试的时候更改的地方会非常多。
所以projectItem中点击 邀请 按钮，只负责把事件发射出去，让父组件知道，不做处理。
所以projectList来处理邀请事件，调起Invite组件。
lauchInviteDialog(){ const dialogRef = this.dialog.open(InviteComponent); }
