Getting started with React TextBox component

25 Oct 202418 minutes to read

This section briefly explains about how to create a simple TextBox using Create React App.

Dependencies

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

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

Installation and Configuration

  • You can use create-react-app to setup the applications.
    To install create-react-app run the following command.

       npm install -g create-react-app

  • Start a new project using create-react-app command as follows.

         create-react-app quickstart --scripts-version=react-scripts-ts
     cd quickstart

  • To install TextBox component, use the following command.

        npm install @syncfusion/ej2-react-inputs –save

  • The above package installs Input dependencies which are required to render the TextBox component in React environment.

  • The TextBox CSS files are available in the ej2-react-inputs package folder. This can be referenced in your application using the following code.

[src/App.css]

@import "../node_modules/@syncfusion/ej2-base/styles/material.css";
@import "../node_modules/@syncfusion/ej2-react-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 TextBox to the application

Return the TextBoxComponent within render method in src/App.tsx file to render the TextBox component as like below code.

[Class-component]

import * as React from "react";
import './App.css';
export default class App extends React.Component<{}, {}> {
    public render() {
      return (
        // element which is going to render the TextBox
        <TextBoxComponent placeholder="Enter Name"></TextBoxComponent>
      );
    }
};

[Functional-component]

import * as React from "react";
import './App.css';
function App() {
    return (
        // element which is going to render the TextBox
         <TextBoxComponent placeholder="Enter Name"></TextBoxComponent>
    );
};
ReactDOM.render(<App />, document.getElementById('input-container'));

Adding icons to the TextBox

You can create a TextBox with an icon by using the addIcon method within the created event. For detailed information, refer to the Groups section.

[Class-component]

import * as React from "react";
import { createRoot } from 'react-dom/client';
import { TextBoxComponent } from '@syncfusion/ej2-react-inputs';

export default class Default extends React.Component {
    public textboxObj = React.createRef();

    public oncreate() {  
        (this.textboxObj.current as any).addIcon('append', 'e-icons e-input-popup-date');
    }

    public render() {
        return (
            <TextBoxComponent
                id='default'
                placeholder="Enter Date"
                ref={this.textboxObj}
                created={this.oncreate}
            />
        );
    }
}

createRoot(document.getElementById('default')).render(<Default />);

[Functional-component]

import * as React from "react";
import { createRoot } from 'react-dom/client';
import { TextBoxComponent } from '@syncfusion/ej2-react-inputs';
import { useRef } from 'react';

function Default()  {
    const textboxObj = useRef(null);

    function oncreate() {  
        textboxObj.current.addIcon('append', 'e-icons e-input-group-icon e-input-popup-date');
    }
    return (
        <TextBoxComponent
            id='default'
            placeholder="Enter Date"
            ref={textboxObj}
            created={oncreate}
        />
    );
};   

createRoot(document.getElementById('default')).render(<Default />);
.e-input-group .e-icons.e-input-group-icon.e-input-popup-date {
    font-size:16px;
}
.e-input-group .e-icons.e-input-group-icon.e-input-popup-date:before {
    content: "\e901";
}

  • Run the application in the browser using the following command.

      npm start

Output will be as follows:

[Class-component]

import * as React from "react";
import { createRoot } from 'react-dom/client';
import { TextBoxComponent } from '@syncfusion/ej2-react-inputs';

export default class Default extends React.Component {
    textBoxObj = React.createRef();

    oncreate = () => {  
        this.textBoxObj.current.addIcon('append', 'e-icons e-input-popup-date');
    }

    render() {
        return (
            <TextBoxComponent
                id='default'
                placeholder="Enter Date"
                ref={this.textBoxObj}
                created={this.oncreate}
            />
        );
    }
}

createRoot(document.getElementById('default')).render(<Default />);
import * as React from "react";
import { createRoot } from 'react-dom/client';

    }

    public render() {
        return (
            <TextBoxComponent
                id='default'
                placeholder="Enter Date"
                ref={this.textBoxObj}
                created={this.oncreate}
            />
        );
    }
}

createRoot(document.getElementById('default')).render(<Default />);

import { useRef } from 'react';

function Default()  {
    textBoxObj = useRef(null);

    function oncreate() {  
        textBoxObj.current.addIcon('append', 'e-icons e-input-popup-date');
    }
    return (
        <TextBoxComponent
            id='default'
            placeholder="Enter Date"
            ref={textBoxObj}
            created={oncreate}
        />
    );
};

        (textBoxObj.current as any).addIcon('append', 'e-icons e-input-popup-date');
    }
    return (
        <TextBoxComponent
            id='default'
            placeholder="Enter Date"
            ref={textBoxObj}
            created={oncreate}
        />
    );
};   

createRoot(document.getElementById('default')).render(<Default />);

Floating Label

The floating label TextBox floats the label above the TextBox after focusing, or filled with value in the TextBox.
You can create the floating label TextBox by using the floatLabelType API.

[Class-component]

import { TextBoxComponent } from '@syncfusion/ej2-react-inputs';
import * as React from "react";
import * as ReactDOM from "react-dom";
export default class App extends React.Component {
    render() {
        return (<div className="App">
                <div className="textboxes">
                    <h4>FloatLabelType as Auto</h4>
                    <TextBoxComponent placeholder="First Name" floatLabelType="Auto"/>
                </div>
                <div className="textboxes">
                    <h4>FloatLabelType as Always</h4>
                    <TextBoxComponent placeholder="Last Name" floatLabelType="Always"/>
                </div>
            </div>);
    }
}
;
ReactDOM.render(<App />, document.getElementById('input-container'));
import { TextBoxComponent } from '@syncfusion/ej2-react-inputs';
import * as React from "react";
import * as ReactDOM from "react-dom";

export default class App extends React.Component<{}, {}> {
    public render() {
        return (
             <div className="App">
                <div className="textboxes">
                    <h4>FloatLabelType as Auto</h4>
                    <TextBoxComponent placeholder="First Name" floatLabelType="Auto"/>
                </div>
                <div className="textboxes">
                    <h4>FloatLabelType as Always</h4>
                    <TextBoxComponent placeholder="Last Name" floatLabelType="Always"/>
                </div>
            </div>
        )
    }
};
ReactDOM.render(<App />, document.getElementById('input-container'));

[Functional-component]

import { TextBoxComponent } from '@syncfusion/ej2-react-inputs';
import * as React from "react";
import * as ReactDOM from "react-dom";
function App() {
    return (<div className="App">
                <div className="textboxes">
                    <h4>FloatLabelType as Auto</h4>
                    <TextBoxComponent placeholder="First Name" floatLabelType="Auto"/>
                </div>
                <div className="textboxes">
                    <h4>FloatLabelType as Always</h4>
                    <TextBoxComponent placeholder="Last Name" floatLabelType="Always"/>
                </div>
            </div>);
}
;
ReactDOM.render(<App />, document.getElementById('input-container'));
import { TextBoxComponent } from '@syncfusion/ej2-react-inputs';
import * as React from "react";
import * as ReactDOM from "react-dom";

    function App() {
        return (
             <div className="App">
                <div className="textboxes">
                    <h4>FloatLabelType as Auto</h4>
                    <TextBoxComponent placeholder="First Name" floatLabelType="Auto"/>
                </div>
                <div className="textboxes">
                    <h4>FloatLabelType as Always</h4>
                    <TextBoxComponent placeholder="Last Name" floatLabelType="Always"/>
                </div>
            </div>
        )
    };

ReactDOM.render(<App />, document.getElementById('input-container'));
