import { Component } from '@angular/core';

@Component({
    selector: 'app-root',
    styleUrls: ['./style.css'],
    template:  `<div class="e-section-control">
                <!-- Primary Button - Used to represent a primary action. -->
                <button ejs-button cssClass="e-primary">Primary</button>

                <!-- Success Button - Used to represent a positive action. -->
                <button ejs-button cssClass="e-success">Success</button>

                <!-- Info Button - Used to represent an informative action -->
                <button ejs-button cssClass="e-info">Info</button>

                <!-- Warning Button - Used to represent an action with caution. -->
                <button ejs-button cssClass="e-warning">Warning</button>

                <!-- Danger Button - Used to represent a negative action. -->
                <button ejs-button cssClass="e-danger">Danger</button>

                <!-- Link Button - Changes the appearance of the Button like a hyperlink. -->
                <button ejs-button cssClass="e-link">Link</button>
                </div>`
})

export class AppComponent { }
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { ButtonModule } from '@syncfusion/ej2-angular-buttons';
import { AppComponent } from './app.component';
import { enableRipple } from '@syncfusion/ej2-base';

enableRipple(true);

/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule,
        ButtonModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent]
})
export class AppModule { }
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

import 'zone.js';
enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

Predefined Button styles provide only the visual indication. So, Button content should define the Button
style for the users of assistive technologies such as screen readers.
Primary action button can also be achieved by setting isPrimary property as true.

import { Component } from '@angular/core';

@Component({
    selector: 'app-root',
    styleUrls: ['./style.css'],
    template:   `<div class="e-section-control">
                    <form>
                        <!-- Submit type button -->

                </div>`
                
})

export class AppComponent { }
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { ButtonModule } from '@syncfusion/ej2-angular-buttons';
import { AppComponent } from './app.component';
import { enableRipple } from '@syncfusion/ej2-base';

enableRipple(true);

/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule,
        ButtonModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent]
})
export class AppModule { }
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

import 'zone.js';
enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

Flat Button

The Flat Button is styled with no background color. To create a flat Button,
set the cssClass property to e-flat.

Outline Button

An outline Button has a border with transparent background. To create an outline Button,
set the cssClass property to e-outline.

Round Button

A round Button is shaped like a circle. Usually, it contains an icon representing its action.
To create a round Button, set the cssClass property to e-round.

import { Component } from '@angular/core';

@Component({
    selector: 'app-root',
    styleUrls: ['./style.css'],
    template:   `<div class="e-section-control">
                <!-- Flat Button. -->
                <button ejs-button cssClass="e-flat">Flat</button>

                <!-- Outline Button. -->
                <button ejs-button cssClass="e-outline">Outline</button>

                <!-- Round Button - Icon can be loaded by setting "e-icons e-plus-icon" in "iconCss" property.-->
                <!-- Use "e-icons" class name to load Essential JS 2 built-in icons.-->
                <!-- Use "e-plus-icon" class name to load plus icon that you can refer in "styles.css" -->
                <button ejs-button cssClass="e-round" iconCss="e-icons e-plus-icon" [isPrimary]="true"></button>
                </div>`
})

export class AppComponent { }
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { ButtonModule } from '@syncfusion/ej2-angular-buttons';
import { AppComponent } from './app.component';
import { enableRipple } from '@syncfusion/ej2-base';

enableRipple(true);

/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule,
        ButtonModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent]
})
export class AppModule { }
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

import 'zone.js';
enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

Toggle Button

A toggle Button allows you to change between the two states. The Button is active in toggled state and can be recognized through the e-active class. The functionality of the toggle Button is handled by click event. To create a toggle Button, set the isToggle
property to true. In the following code snippet, the toggle Button text changes to play/pause based on the state of the Button with the use of click event.

import { Component, ViewChild, HostListener } from '@angular/core';
import { ButtonComponent } from '@syncfusion/ej2-angular-buttons';

@Component({
    selector: 'app-root',
    styleUrls: ['./style.css'],
    template: `<div class="e-section-control">
                    <!-- Button is active in toggled state. -->
                    <button #togglebtn ejs-button cssClass="e-flat" iconCss="e-btn-sb-icon e-play-icon" [isToggle]="true" content="Play"></button>
                </div>`
})
// Click event handled using HostListener.
export class AppComponent {
    @ViewChild('togglebtn') togglebtn: ButtonComponent | any;
    @HostListener('click', ['togglebtn'])
    btnClick() {
        if(this.togglebtn.element.classList.contains('e-active')){
            this.togglebtn.content = 'Pause';
            this.togglebtn.iconCss = 'e-btn-sb-icon e-pause-icon';
        }
        else {
            this.togglebtn.content = 'Play';
            this.togglebtn.iconCss = 'e-btn-sb-icon e-play-icon';
        }
    }
 }
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { ButtonModule } from '@syncfusion/ej2-angular-buttons';
import { AppComponent } from './app.component';
import { enableRipple } from '@syncfusion/ej2-base';

enableRipple(true);

/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule,
        ButtonModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent]
})
export class AppModule { }
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

import 'zone.js';
enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

Icons

Button with font icons

The Button can have an icon to provide the visual representation of the action. To place the icon on a Button,set the iconCss property with the required icon CSS. By default, the icon is positioned to the left side of the Button. You can customize the icon’s position
by using the iconPosition property.

import { Component } from '@angular/core';

@Component({
    selector: 'app-root',
    styleUrls: ['./style.css'],
    template:  `<div class="e-section-control">
                    <!-- To position the icon to the left of the text on a Button. -->
                    <button ejs-button iconCss="e-btn-sb-icon e-prev-icon">Previous</button>

                    <!-- To position the icon to the right of the text on a Button. -->
                    <button ejs-button iconCss= "e-btn-sb-icon e-stop-icon" iconPosition="Right">Stop</button>
                </div>`
})

export class AppComponent { }
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { ButtonModule } from '@syncfusion/ej2-angular-buttons';
import { AppComponent } from './app.component';
import { enableRipple } from '@syncfusion/ej2-base';

enableRipple(true);

/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule,
        ButtonModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent]
})
export class AppModule { }
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

import 'zone.js';
enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

Button with SVG image

SVG image can be added to the Button using iconCss property.

In the following example, SVG image is added using the iconCss class e-search-icon by setting height and width.

import { Component } from '@angular/core';

@Component({
    selector: 'app-root',
    styleUrls: ['styles.css'],
    template:  `<div class="e-section-control">
                    <button ejs-button iconCss= "e-search-icon"></button>
                </div>`
})

export class AppComponent { }
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { ButtonModule } from '@syncfusion/ej2-angular-buttons';
import { AppComponent } from './app.component';
import { enableRipple } from '@syncfusion/ej2-base';

enableRipple(true);

/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule,
        ButtonModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent]
})
export class AppModule { }
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

import 'zone.js';
enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

The Essential JS 2 provides a set of icons that can be loaded by applying e-icons class name to the element. You can also use third party icons on the Button using the iconCss property.

Button size

The two types of Button sizes are default and small. To change the size of the default Button to small Button, set the cssClass property to e-small.

import { Component } from '@angular/core';

@Component({
    selector:  'app-root',
    styleUrls: ['./style.css'],
    template:   `<div class="e-section-control">
                    <!-- Small Button. -->
                    <button ejs-button cssClass="e-small">Small</button>

                    <!-- Normal Button. -->
                    <button ejs-button>Normal</button>
                </div>`
})

export class AppComponent { }
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { ButtonModule } from '@syncfusion/ej2-angular-buttons';
import { AppComponent } from './app.component';
import { enableRipple } from '@syncfusion/ej2-base';

enableRipple(true);

/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule,
        ButtonModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent]
})
export class AppModule { }
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

import 'zone.js';
enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);
