Angular 6 Material
Material为你的项目提供了许多内置模块。自动完成、日期选择器、滑块、菜单、网格和工具栏等功能可用于Angular 6中的Material。
要使用Material,我们需要导入包。Angular 2也具有上述所有特性,但它们是@angular/core模块的一部分。Angular 6是一个单独的模块@angular/materials,这有助于用户导入所需的Material。
要开始使用Material,您需要安装两个软件包:materials 和 cdk。Material组件依赖于高级特征的动画模块,因此您需要导入动画包,即@angular/animations。上一章已经介绍了该包。
npm install --save @angular/material @angular/cdk
现在让我们看看package.json,@angular/material和@angular/cdk已被安装。

}
}我们现在将在父模块app.module.ts中导入模块,如下所示
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { MatButtonModule, MatMenuModule, MatSidenavModule } from '@angular/material';
import { FormsModule } from '@angular/forms';
import { AppComponent } from './app.component';
@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,
BrowserAnimationsModule,
MatButtonModule,
MatMenuModule,
FormsModule,
MatSidenavModule
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }在上述文件中,我们从@angular/materials导入了以下模块。
import { MatButtonModule, MatMenuModule, MatSidenavModule } from '@angular/material';导入数组中也使用了相同的方法,如下所示:
imports: [ BrowserModule, BrowserAnimationsModule, MatButtonModule, MatMenuModule, FormsModule, MatSidenavModule ]
app.component.ts如下所示:
import { Component } from '@angular/core';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
myData: Array<any>;
constructor() {}
}现在让我们在styles.css中添加material-css支持。
@import "~@angular/material/prebuilt-themes/indigo-pink.css";
现在让我们在app.component.html加上material。
<button mat-button [matMenuTriggerFor] = "menu">Menu</button> <mat-menu #menu = "matMenu"> <button mat-menu-item> File </button> <button mat-menu-item> Save As </button> </mat-menu> <mat-sidenav-container class = "example-container"> <mat-sidenav #sidenav class = "example-sidenav"> Angular 6 </mat-sidenav> <div class = "example-sidenav-content"> <button type = "button" mat-button (click) = "sidenav.open()"> Open sidenav </button> </div> </mat-sidenav-container>
在上面的文件中,我们添加了菜单和侧边导航。
菜单
要添加菜单,请使用<mat-menu></mat-menu>。文件和另存为项目被添加到mat-menu下的按钮。添加了一个主按钮菜单。通过使用[matMenuTriggerFor]="menu" ,并使用<mat-menu>中带有#的菜单,可以在<mat-menu>中给出相同的参考。
侧边导航
要添加侧边导航,我们需要<mat-sidenav-container></mat-sidenav-container>。<mat-sidenav></mat-sidenav>作为子导航添加到容器中。增加了另一个div,通过使用(click)="sidenav.open()"来触发sidenav。以下是浏览器中菜单和侧面导航的显示

单击opensidenav,它会显示如下所示的侧栏

单击菜单,您将看到两个项目:文件和另存,如下所示。

现在让我们使用materials添加一个日期选择器。要添加日期选择器,我们需要导入显示日期选择器所需的模块。
在app.module.ts中,我们为日期选择器导入了如下所示的模块。
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { MatDatepickerModule, MatInputModule, MatNativeDateModule } from '@angular/material';
import { FormsModule } from '@angular/forms';
import { AppComponent } from './app.component';
@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,
BrowserAnimationsModule,
FormsModule,
MatDatepickerModule,
MatInputModule,
MatNativeDateModule
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }这里,我们导入了一些模块,如MatDatepickerModule、MatInputModule和MatNativeDateModule。
现在,app.component.ts如下所示:
import { Component } from '@angular/core';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
myData: Array<any>;
constructor() {}
}app.component.html如下所示:
<mat-form-field> <input matInput [matDatepicker] = "picker" placeholder = "Choose a date"> <mat-datepicker-toggle matSuffix [for] = "picker"></mat-datepicker-toggle> <mat-datepicker #picker></mat-datepicker> </mat-form-field>
这就是日期选择器在浏览器中的显示方式。
