详解Angular项目中共享模块的实现

一、共享CommonModule

创建share Modele：ng g m share

import进来所有需要共享的模块都export出去，

暂时只有CommonModule,以后会有一些需要共享的组件。

import { NgModule } from '@angular/core'; import { CommonModule } from '@angular/common'; @NgModule({ imports: [ CommonModule ], exports:[ CommonModule ], declarations: [] }) export class SharedModule { }

在app Module中把core Module导入进来。

import { BrowserModule } from '@angular/platform-browser'; import { NgModule } from '@angular/core'; import { AppComponent } from './app.component'; import {CoreModule} from './core/core.module'; @NgModule({ declarations: [ AppComponent ], imports: [ BrowserModule, CoreModule ], providers: [], bootstrap: [AppComponent] }) export class AppModule { }

二、共享MaterialModule

为了方便管理，把Material相关组件的导入导出单独放在一个Moduel中，在ShareModule中导入导出即可。

import { NgModule } from '@angular/core'; import { CommonModule } from '@angular/common'; import { MatToolbarModule, MatSidenavModule, MatButtonModule, MatCardModule, MatInputModule, MatListModule, MatSlideToggleModule, MatGridListModule, MatDialogModule, MatAutocompleteModule, MatMenuModule, MatCheckboxModule, MatTooltipModule, MatDatepickerModule, MatRadioModule, MatNativeDateModule, MatSelectModule } from '@angular/material'; import { MatIconModule } from '@angular/material'; const module=[ MatSidenavModule, MatIconModule, MatToolbarModule, MatIconModule, MatButtonModule, MatCardModule, MatInputModule, MatListModule, MatSlideToggleModule, MatGridListModule, MatDialogModule, MatAutocompleteModule, MatMenuModule, MatCheckboxModule, MatTooltipModule, MatDatepickerModule, MatRadioModule, MatNativeDateModule, MatSelectModule ]; @NgModule({ declarations: [], imports: [ module ], exports:[ module ] }) export class MaterialModule { }

import { NgModule } from '@angular/core'; import { CommonModule } from '@angular/common'; import { MaterialModule } from '../material/material.module'; import { ConfirmDialogComponent } from './confirm-dialog/confirm-dialog.component'; @NgModule({ imports: [ CommonModule, MaterialModule ], exports:[ CommonModule, MaterialModule ], declarations: [ConfirmDialogComponent] }) export class SharedModule { }

三、共享ConfirmDialog

确认对话框不管是在删除任务还是在删除项目中都会用到，所以放在sharedModule中。

$ ng g c shared/confirm-dialog

也可以通过ng g c shared/confirm-dialog -it -is建一个内联的template和style

<form> <h2 md-dialog-title>{{title}}</h2> <div mat-dialog-content> {{content}} </div> <div mat-dialog-actions> <button type="button" mat-raised-button color="primary" (click)="onClick(true)">确定</button> <button type="button" mat-button mat-dialog-close (click)="onClick(false)">取消</button> </div> </form>

import { Component, OnInit, Inject } from "@angular/core"; import { MatDialogRef } from "@angular/material"; import { MAT_DIALOG_DATA } from "@angular/material"; @Component({ selector: "app-confirm-dialog", templateUrl: "./confirm-dialog.component.html", styleUrls: ["./confirm-dialog.component.scss"] }) export class ConfirmDialogComponent implements OnInit { title = ""; content = ""; constructor( private dialogRef: MatDialogRef<ConfirmDialogComponent>, @Inject(MAT_DIALOG_DATA) private data ) { } ngOnInit() { this.title = this.data.title; this.content = this.data.content; } onClick(result: boolean) { this.dialogRef.close(result); } }

然后把ConfirmDialogComponent组件放在sharedModule中。

import { NgModule } from "@angular/core"; import { CommonModule } from "@angular/common"; import { MaterialModule } from "../material/material.module"; import { ConfirmDialogComponent } from "./confirm-dialog/confirm-dialog.component"; @NgModule({ imports: [CommonModule, MaterialModule], exports: [CommonModule, MaterialModule], declarations: [ConfirmDialogComponent], entryComponents: [ConfirmDialogComponent] }) export class SharedModule { }

如果使用ConfirmDialog，可参考删除project。
