11 Jul 20246 minutes to read
This section briefly explains about how to create a simple TextArea component using Angular seed repository.
Dependencies
The following list of dependencies are required to use the TextArea 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-textarea
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-textarea --style=scss
Navigate to the created project folder.
cd syncfusion-angular-textarea
Installing syncfusion TextArea 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,
- Ivy library distribution package format
- 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.
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.
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.
@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 TextArea to the application
- Modify the template in
app.component.ts
file to render theTextArea
component.
import {TextAreaModule} from '@syncfusion/ej2-angular-inputs'
import { Component } from '@angular/core';
@Component({
imports: [
TextAreaModule
],
standalone: true,
selector: 'app-root',
template: `<textarea id="default"></textarea>`
})
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.
Running the application
After completing the configuration required to render a basic TextArea, run the following command to display the output in your default browser.
ng serve
The following example illustrates the output in your browser.
import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import {TextAreaModule} from '@syncfusion/ej2-angular-inputs'
import { Component } from '@angular/core';
import { TextBoxComponent } from '@syncfusion/ej2-angular-inputs';
@Component({
imports: [
TextAreaModule
],
standalone: true,
selector: 'app-root',
template: `<div class="wrap">
<div class='textarea'>
<ejs-textarea id="default"></ejs-textarea>
</div>
</div>`
})
export class AppComponent { }
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));
Getting and setting values
To set the initial value of the TextArea component, you can utilize the value
property. Here’s how you can achieve it:
import { Component } from '@angular/core';
@Component({
selector: 'app-root',
template: `<!-- To Render TextArea component. -->
<div class='wrap'>
<ejs-textarea id="default" value="comments"></ejs-textarea>
</div>`
})
export class AppComponent { }
- Alternatively, you can set the value of the TextArea using ng-model.
import { Component } from '@angular/core';
@Component({
selector: 'app-root',
template: `
<div class='wrap'>
<ejs-textarea id="default" [(ngModel)]="value"></ejs-textarea>
</div>
`
})
export class AppComponent {
value: string = 'Comments'; // Set the initial value here
}
- You can dynamically retrieve the value of the TextArea component using the value property bound to
ng-model
of the TextArea component.
import { Component } from '@angular/core';
@Component({
selector: 'app-root',
template: `
<div class='wrap'>
<ejs-textarea id="default" [(ngModel)]="value"></ejs-textarea>
<button id="valuebtn" (click)="onButtonClick()">Get Value</button>
</div>
`
})
export class AppComponent {
value: string = 'Comments'; // Set the initial value here
onButtonClick() {
// Get the value of the TextArea
let textareaValue = this.value;
}
}
- You can retrieve the value of the TextArea by accessing it as an argument from the
change
event.
import { Component } from '@angular/core';
import { ChangedEventArgs } from '@syncfusion/ej2-angular-inputs';
@Component({
selector: 'app-root',
template: `<!-- To Render TextArea component. -->
<div class="wrap">
<input id='default' (Change)="onChange($event)"/><br />
</div>`
})
export class AppComponent {
public onChange(args: ChangedEventArgs) {
// get the value of the TextArea component
let textareaValue = args.value;
};
}
