Getting started

This section explains you the steps required to create a simple TimePicker and demonstrate the basic usage of the TimePicker component.

Dependencies

The below list of dependencies are required to use the TimePicker component in your application.

|-- @syncfusion/ej2-react-calendars
    |-- @syncfusion/ej2-react-base
        |-- @syncfusion/ej2-base
    |-- @syncfusion/ej2-data
    |-- @syncfusion/ej2-calendars
        |-- @syncfusion/ej2-inputs
            |-- @syncfusion/ej2-splitbuttons
        |-- @syncfusion/ej2-lists
        |-- @syncfusion/ej2-popups
            |-- @syncfusion/ej2-buttons

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
  • To setup basic React sample use following commands.
create-react-app quickstart --scripts-version=react-scripts-ts

cd quickstart

Adding Syncfusion packages

All the available Essential JS 2 packages are published in npmjs.com public registry. You can choose the component that you want to install. For this application, we are going to use TimePicker component.

To install TimePicker component, use the following command

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

Adding Style sheet to the Application

To render the TimePicker component, need to import TimePicker and its dependent component’s styles as given below in App.css.

@import "../node_modules/@syncfusion/ej2-base/styles/material.css";
@import "../node_modules/@syncfusion/ej2-inputs/styles/material.css";
@import "../node_modules/@syncfusion/ej2-popups/styles/material.css";
@import "../node_modules/@syncfusion/ej2-lists/styles/material.css";
@import "../node_modules/@syncfusion/ej2-react-calendars/styles/material.css";

Note: If you want to refer the combined component styles, please make use of our CRG (Custom Resource Generator) in your application.

Adding TimePicker component to the Application

  • To include the TimePicker component in application import the TimePickerComponent from ej2-react-calendars package in App.tsx.

  • Then add the TimePicker component as shown in below code example.

[src/App.tsx]

import { enableRipple } from '@syncfusion/ej2-base';
import { TimePickerComponent } from '@syncfusion/ej2-react-calendars';
import * as React from "react";
import './App.css';
// enable ripple effect
enableRipple(true);

export default class App extends React.Component<{}, {}> {
    public render() {
        return <TimePickerComponent id="time" />
    }
};

Run the application

Now run the npm start command in the console, it will run your application and open the browser window.

npm start

The following examples shows the basic TimePicker component.

Source
Preview
index.tsx
// import the ripple effect
import { enableRipple } from '@syncfusion/ej2-base';
// import the timepicker
import { TimePickerComponent } from '@syncfusion/ej2-react-calendars';
import * as React from "react";
import * as ReactDOM from "react-dom";
// enable ripple effect
enableRipple(true);

export default class App extends React.Component<{}, {}> {
    public render() {
        return <TimePickerComponent id="timepicker" placeholder="Select a Time" />
    }
};
ReactDOM.render(<App />, document.getElementById('timer'));

Now, the TimePicker renders with default culture as American English(‘en-US’). For a different culture, refer to the Globalization section.

Setting the value, min, and max time

The following example demonstrates how to set the value, min and max time on initializing the TimePicker. Here the TimePicker allows you to select the time value within a range from 7:00 AM to 4:00 PM.

Source
Preview
index.tsx
// import the ripple effect
import { enableRipple } from '@syncfusion/ej2-base';
// import the timepicker
import { TimePickerComponent } from '@syncfusion/ej2-react-calendars';
import * as React from "react";
import * as ReactDOM from "react-dom";
// enable ripple effect
enableRipple(true);

export default class App extends React.Component<{}, {}> {

    // initialize the value, min and max time
    private time: Date = (new Date('8/3/2017 10:00 AM'));
    private minTime: Date = (new Date('8/3/2017 7:00 AM'));
    private maxTime: Date = (new Date('8/3/2017 4:00 PM'));

    public render() {
        return <TimePickerComponent id="timepicker" value={this.time} min={this.minTime} max={this.maxTime} />
    }
};
ReactDOM.render(<App />, document.getElementById('timer'));

Setting the time format

Time formats is a way of representing the time value in different string format in textbox and popup list. By default, the TimePicker’s format is based on the culture. You can also customize the format by using the format property. To know more about the time format standards, refer to the Date and Time Format section.

The following example demonstrates the TimePicker component in 24 hours format with 60 minutes interval. The time interval is set to 60 minutes by using the step property.

Source
Preview
index.tsx
// import the ripple effect
import { enableRipple } from '@syncfusion/ej2-base';
// import the timepicker
import { TimePickerComponent } from '@syncfusion/ej2-react-calendars';
import * as React from "react";
import * as ReactDOM from "react-dom";
// enable ripple effect
enableRipple(true);

export default class App extends React.Component<{}, {}> {

    private time: Date = (new Date('8/3/2017 10:00'));

    public render() {
        return <TimePickerComponent id="timepicker" value={this.time} step={60} format={'HH:mm'} />
    }
};

ReactDOM.render(<App />, document.getElementById('timer'));

Once the time format property is defined, it will be applicable to all the cultures.
