Angular MDBootstrap Switch Component

MDBootstrap is a Material Design and bootstrap-based Angular UI library that is used to make attractive webpages with its seamless and easy-to-use component. In this article, we will see how to use Switch Component in Angular MDBootstrap.

The Switch Component is used to indicate the on/off state of the component. The switch can be utilized to perform the On/Off functionality or provide the preference to choose one of two predefined options.

Syntax:

<div class="custom-control custom-switch">
  <input type="checkbox" class="custom-control-input">
  <label class="custom-control-label">Switch</label>
</div>

Approach:

• Download Angular MDBootstrap from the official site.
• Extract the files to the current working directory.
• Install npm in the current project using the following command:

npm install

• After creating your project folder i.e. appname, move to it using the following command:

cd appname

• Start the server using the following command:

ng serve

Project Structure: After complete installation, it will look like the following:

Example 1: This is the basic example that illustrates how to use the Switch component in Angular MDBootstrap. Here, we have implemented the default & the checked switch.

app.component.html

<div id="gfg">
    <h1>GeeksforGeeks</h1>
    <h4>
        Angular MDBootstrap Switch Component
    </h4>
    <br />
    <div class="custom-control custom-switch">
        <input type="checkbox"
               class="custom-control-input"
               id="customSwitches">
        <label class="custom-control-label"
               for="customSwitches">
            Switch
        </label>
    </div>
    <br/>
    <div class="custom-control custom-switch">
        <input type="checkbox"
               class="custom-control-input"
               id="gfg1"
               checked>
        <label class="custom-control-label"
               for="gfg1">
            Switch
        </label>
    </div>
</div>

app.component.ts

import { AfterViewInit, Component, ViewChildren } from "@angular/core";

@Component({
  selector: "app-root",
  templateUrl: "./app.component.html",
  styleUrls: ["./app.component.css"],
})
export class AppComponent implements AfterViewInit {
  @ViewChildren(AppComponent) collapses!: AppComponent[];

  ngAfterViewInit(): void {}
  togglevisible = false;

  togglebg() {
    this.togglevisible = !this.togglevisible;
  }
}

app.module.ts

import { BrowserModule } from "@angular/platform-browser";
import { NgModule } from "@angular/core";
import { BrowserAnimationsModule }
    from "@angular/platform-browser/animations";

import { AppComponent } from "./app.component";
import { MDBBootstrapModule } from "angular-bootstrap-md";
import { FormsModule } from "@angular/forms";

@NgModule({
  declarations: [AppComponent],
  imports: [
    BrowserModule,
    BrowserAnimationsModule,
    MDBBootstrapModule.forRoot(),
    FormsModule,
  ],
  providers: [],
  bootstrap: [AppComponent],
})
export class AppModule {}

Output:

Example 2: In this example, we will know how to disable the Switch component in Angular MDBootstrap.

app.component.html

<div id="gfg">
    <h1>GeeksforGeeks</h1>
    <h4>
        Angular MDBootstrap Switch Component
    </h4>
    <br />
    <div class="custom-control custom-switch">
        <input type="checkbox"
               class="custom-control-input"
               id="gfg1" disabled>
        <label class="custom-control-label"
               for="gfg1">
            Switch
        </label>
    </div>
</div>

app.component.ts

import { AfterViewInit, Component, ViewChildren } from "@angular/core";

@Component({
  selector: "app-root",
  templateUrl: "./app.component.html",
  styleUrls: ["./app.component.css"],
})
export class AppComponent implements AfterViewInit {
  @ViewChildren(AppComponent) collapses!: AppComponent[];

  ngAfterViewInit(): void {}
  togglevisible = false;

  togglebg() {
    this.togglevisible = !this.togglevisible;
  }
}

app.module.ts

import { BrowserModule } from "@angular/platform-browser";
import { NgModule } from "@angular/core";
import { BrowserAnimationsModule }
    from "@angular/platform-browser/animations";

import { AppComponent } from "./app.component";
import { MDBBootstrapModule } from "angular-bootstrap-md";
import { FormsModule } from "@angular/forms";
