Material(包括Material Icon)在Angular2中的使用

ngx-material相關網址

​ 目前咱們使用的是angular5,所以咱們選擇ngx-material v5版本。css

  1. 官網地址
  2. github地址
  3. demo代碼地址

引入material

  1. 引入material npm包以及相關的包html

    npm install @angular/material @angular/cdk 
    複製代碼
  2. 由於一些Angular Material組件依賴Angular animations模塊,因此在使用Angular Material時須要安裝@angular/animations模塊(新建項目時會有,若是沒有,在第一步中一塊兒安裝@angular/animations),而且須要導入BrowserAnimationsModulenode

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

3.新建一個module統一管理material的module引入git

ng g module ebiz-material
複製代碼

4.在app的根module中引入ebiz-material.module.tsgithub

```typescript
import { EbizMaterialModule } from './ebiz-material/ebiz-material.module';
@NgModule({
    imports: [..., EbizMaterialModule],
    declarations: [
        ...
    ],
    schemas: [CUSTOM_ELEMENTS_SCHEMA]
})
複製代碼

使用material組件

  1. 首先在ebiz-material.module.ts中引入material組件的module,例如咱們要用到checkbox,那就引入MatCheckboxModule,引入以後再exports。typescript

    import { NgModule } from '@angular/core';
    import { CommonModule } from '@angular/common';
    import { MatCheckboxModule } from '@angular/material';
    
    @NgModule({
      imports: [CommonModule, MatCheckboxModule],
      declarations: [],
      exports: [ MatCheckboxModule ]
    })
    export class EbizMaterialModule { }
    
    複製代碼
  2. 在html文件中使用組件npm

<mat-checkbox [(ngModel)]="checked">Check me!</mat-checkbox>
複製代碼
  1. 此時會報錯
    compiler.js:485 Uncaught Error: Template parse errors:
     Can't bind to 'ngModel' since it isn't a known property of 'mat-checkbox'.
     1. If 'mat-checkbox' is an Angular component and it has 'ngModel' input, then verify that it is part of this module.
     2. If 'mat-checkbox' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message.
     3. To allow any property add 'NO_ERRORS_SCHEMA' to the '@NgModule.schemas' of this component. ("<mat-checkbox [ERROR ->][(ngModel)]="checked"> Check me!</mat-checkbox>"): ng:///AppModule/AppComponent.html@0:14

         at Object.then (compiler.js:474)
         at JitCompiler._compileModuleAndComponents (compiler.js:34365)
    複製代碼
    按照錯誤提示,在app.module.ts中引入CUSTOM_ELEMENTS_SCHEMA
    import { BrowserModule } from '@angular/platform-browser';
    import { NgModule, CUSTOM_ELEMENTS_SCHEMA } from '@angular/core';
    
    import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
    import { AppComponent } from './app.component';
    import { MaterialModule } from './material/material.module';
    import { RouterModule } from '@angular/router';
    
    @NgModule({
    declarations: [
      AppComponent
    ],
    imports: [
      BrowserModule,
      BrowserAnimationsModule,
      MaterialModule,
      RouterModule.forRoot([
        {
          path: '',
          component: AppComponent
        }
      ])
    ],
    providers: [],
    bootstrap: [AppComponent],
    schemas: [CUSTOM_ELEMENTS_SCHEMA]
    })
    export class AppModule { }
    複製代碼

使用material內置theme以及自定義theme

  1. material中的組件會根據theme的不一樣,會有不同的樣式呈現,可是這些樣式的不一樣只侷限於material組件內部,不會影響自定義組件的樣式。json

  2. 在style.css文件中引入material預建主題(總共4個)bootstrap

    @import '~@angular/material/prebuilt-themes/deeppurple-amber.css'; 
     @import '~@angular/material/prebuilt-themes/indigo-pink.css'; 
     @import '~@angular/material/prebuilt-themes/pink-bluegrey.css';  
     @import '~@angular/material/prebuilt-themes/purple-green.css'; 
    複製代碼

    若是報下面這個錯,只要將angular-cli的版本從1.6.4下降到1.6.3就能夠解決bash

    ERROR in ./node_modules/css-loader?{"sourceMap":false,"import":false}!./node_modules/postcss-loader/lib?{"ident":"postcss","sourceMap":false}!./src/styles.css
        Module build failed: Error: Can't resolve '~@angular/material/prebuilt-themes/deeppurple-amber.css' in 'D:\ebizprise\material-demo\src' 複製代碼
  3. 若是以爲這些主題不適合,能夠自定義主題,在styles.css同級目錄下新建一個theme.scss,並寫上自定義主題的內容

    @import '~@angular/material/theming';
    @include mat-core();
    $my-app-primary: mat-palette($mat-blue); 
    $my-app-accent: mat-palette($mat-teal, A200, A100, A400); 
    $my-app-warn: mat-palette($mat-red); 
    $my-app-theme: mat-light-theme($my-app-primary, $my-app-accent, $my-app-warn);
    @include angular-material-theme($my-app-theme);
    複製代碼

    在style.css中引入theme.scss自定義主題,

    @import './theme';
    複製代碼

    此時會報下面這個錯誤

ERROR in ./node_modules/css-loader?		{"sourceMap":false,"importLoaders":1}!./node_modules/postcss-loader/lib?{"ident":"postcss","sourceMap":false}!./src/styles.css
    Module not found: Error: Can't resolve './theme' in 'D:\ebizprise\material-demo\src' 複製代碼

能夠將所有的css文件修改成scss文件,而且在angular-cli.json文件中修改成

"styleExt": "scss",
複製代碼

也不能忘記angular-cli.json中引入style.css改成style.scss 5. 在步驟3中用到了一些顏色,例如$mat-blue,能夠參考這裏

  1. 若是想要對某個組件進行主題特製,能夠參考這裏

安裝hammerjs(手勢操做才須要)

  1. 安裝hammerjs

    npm install --save hammerjs
    複製代碼
  2. 在程序的入口(src/main.ts)引入hammerjs

    import 'hammerjs';
    複製代碼

使用material-icon

  1. install material-icon

    npm install material-design-icons
    複製代碼
  2. 在style.scss中引入material-icon圖標庫

    @import '~material-design-icons/iconfont/material-icons.css';
    複製代碼
  3. 在ebiz-material.module.ts中引入MatIconModule

    import { MatIconModule } from '@angular/material';
    
    @NgModule({
      imports: [
        ...
        MatIconModule
        ...
      ],
      exports: [
        ...
        MatIconModule
        ...
      ]
    })
    複製代碼
  4. 在html的適當位置放上圖標

    <mat-icon>menu<mat-icon>
    複製代碼

使用其餘圖標庫

  1. 將從網上下載的圖標庫放入到assets文件夾

  2. 在index.html中引入圖標庫

    <!doctype html>
    <html lang="en">
    <head>
      <meta charset="utf-8">
      <title>EbizWorkspace</title>
      <base href="/">
      <meta name="viewport" content="width=device-width, initial-scale=1">
      <link rel="icon" type="image/x-icon" href="favicon.ico">
      <link href="assets/icons/style.css" rel="stylesheet">
    </head>
    <body>
      <app-root></app-root>
    </body>
    </html>
    複製代碼
  3. 在app.component.ts中註冊圖標庫

    import { Component, OnInit } from '@angular/core';
    import { MatIconRegistry } from '@angular/material';
    import { DomSanitizer } from '@angular/platform-browser';
    @Component({
      selector: 'app-root',
      templateUrl: './app.component.html',
      styleUrls: ['./app.component.css']
    })
    export class AppComponent implements OnInit {
      constructor(private matIconRegistry: MatIconRegistry) {
        this.matIconRegistry.registerFontClassAlias('icomoon', 'icon');
      }
    
      ngOnInit() { }
    }
    
    複製代碼
  4. 在html中使用

    <mat-icon fontSet="icomoon" fontIcon="icon-treeview" ></mat-icon>
    複製代碼
