08 Apr 2021 / 4 minutes to read

This section briefly explains about how to create a simple TextBox through CSS classes using Angular seed repository.

Dependencies

The following list of dependencies are required to use the TextBox component in your application.

|-- @syncfusion/ej2-angular-inputs
    |-- @syncfusion/ej2-angular-base
    |-- @syncfusion/ej2-inputs
        |-- @syncfusion/ej2-base

Setup angular environment

Angular provides the easiest way to set angular CLI projects using Angular CLI tool.

Install the CLI application globally to your machine.

npm install -g @angular/cli

Create a new application

ng new syncfusion-angular-textbox

By default, it install the CSS style base application. To setup with SCSS, pass —style=scss argument on create project.

Example code snippet.

ng new syncfusion-angular-textbox --style=scss

Navigate to the created project folder.

cd syncfusion-angular-textbox

Adding TextBox package

All the available Essential JS 2 packages are published in npmjs.com registry.

To install TextBox component, use the following command.

npm install @syncfusion/ej2-angular-inputs --save
(or)
npm i @syncfusion/ej2-angular-inputs --save

The —save will instruct NPM to include the TextBox package inside of the dependencies section of the package.json.

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.

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.

@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);
}
}
