cd syncfusion-angular-textbox

Installing Syncfusion TextBox Package

Syncfusion packages are distributed in npm as @syncfusion scoped packages. You can get all the Angular Syncfusion package from npm link.

Currently, Syncfusion provides two types of package structures for Angular components,

  1. Ivy library distribution package format
  2. Angular compatibility compiler(Angular’s legacy compilation and rendering pipeline) package.

Ivy library distribution package

Syncfusion Angular packages(>=20.2.36) has been moved to the Ivy distribution to support the Angular Ivy rendering engine and the package are compatible with Angular version 12 and above. To download the package use the below command.

Add @syncfusion/ej2-angular-inputs package to the application.

Copied to clipboard
npm install @syncfusion/ej2-angular-inputs --save

Angular compatibility compiled package(ngcc)

For Angular version below 12, you can use the legacy (ngcc) package of the Syncfusion Angular components. To download the ngcc package use the below.

Add @syncfusion/ej2-angular-inputs@ngcc package to the application.

Copied to clipboard
npm install @syncfusion/ej2-angular-inputs@ngcc --save

To mention the ngcc package in the package.json file, add the suffix -ngcc with the package version as below.

Copied to clipboard
@syncfusion/ej2-angular-inputs:"20.2.38-ngcc"

Note: If the ngcc tag is not specified while installing the package, the Ivy Library Package will be installed and this package will throw a warning.

Adding TextBox to the application

  • Modify the template as HTML input element with e-inputclass in app.component.ts file to render the TextBox component.
Copied to clipboard
import { Component } from '@angular/core';

@Component({
selector: 'app-root',
template: `<input class="e-input" type="text" placeholder="Enter Name" />`
})

export class AppComponent { }

Adding CSS reference

The following CSS files are available in ../node_modules/@syncfusion package folder. This can be referenced in [src/styles.css] using following code.

Copied to clipboard
@import '../node_modules/@syncfusion/ej2-base/styles/material.css';
@import '../node_modules/@syncfusion/ej2-inputs/styles/material.css';
@import '../node_modules/@syncfusion/ej2-angular-inputs/styles/material.css';

The Custom Resource Generator (CRG) is an online web tool, which can be used to generate the custom script and styles for a set of specific components. This web tool is useful to combine the required component scripts and styles in a single file.

Adding icons to the TextBox

You can create a TextBox with icon as a group by creating the parent div element with the class e-input-group and add the icon element as span with the class e-input-group-icon. For detailed information, refer to the Groups section.

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

@Component({
selector: 'app-root',
template: `<div class="wrap">
            <div class="e-input-group">
            <input class="e-input" name='input' type="text" (focus)="focusIn($event.target)"
            placeholder = "Enter Date" (blur)="focusOut($event.target)"/>
            <span class="e-input-group-icon e-input-popup-date" (mouseup)="onMouseUp($event.target)" (mousedown)="onMouseDown($event.target)"></span>
            </div>
          </div>`
})

export class AppComponent {
public focusIn(target: HTMLElement): void {
    target.parentElement.classList.add('e-input-focus');
}

public focusOut(target: HTMLElement): void {
    target.parentElement.classList.remove('e-input-focus');
}

public onMouseDown(target: HTMLElement): void {
    target.classList.add('e-input-btn-ripple');
}

public onMouseUp(target: HTMLElement): void {
    let ele: HTMLElement = target;
    setTimeout(
            () => {ele.classList.remove('e-input-btn-ripple'); },
            500);
}
}
