Getting started in EJ2 TypeScript Timepicker control
3 Nov 202312 minutes to read
This section briefly explains how to create a simple TimePicker component, and configure its available functionalities in TypeScript
using Essential JS 2 quickstart seed repository.
This application is integrated with the
webpack.config.js
configuration and uses the latest version of the webpack-cli. It requires nodev14.15.0
or higher. For more information about webpack and its features, refer to the webpack documentation.
Dependencies
Install the below required dependency package in order to use the TimePicker
component in your application.
|-- @syncfusion/ej2-calendars
|-- @syncfusion/ej2-base
|-- @syncfusion/ej2-data
|-- @syncfusion/ej2-inputs
|-- @syncfusion/ej2-splitbuttons
|-- @syncfusion/ej2-lists
|-- @syncfusion/ej2-popups
|-- @syncfusion/ej2-buttons
Set up development environment
Open the command prompt from the required directory, and run the following command to clone the Syncfusion JavaScript (Essential JS 2) quickstart project from GitHub.
git clone https://github.com/SyncfusionExamples/ej2-quickstart-webpack- ej2-quickstart
After cloning the application in the ej2-quickstart
folder, run the following command line to navigate to the ej2-quickstart
folder.
cd ej2-quickstart
Add Syncfusion JavaScript packages
Syncfusion JavaScript (Essential JS 2) packages are available on the npmjs.com public registry. You can install all Syncfusion JavaScript (Essential JS 2) controls in a single @syncfusion/ej2 package or individual packages for each control.
The quickstart application is preconfigured with the dependent @syncfusion/ej2 package in the ~/package.json
file. Use the following command to install the dependent npm packages from the command prompt.
npm install
Import the Syncfusion CSS styles
To render the TimePicker component, need to import TimePicker and its dependent component’s styles as given below in the ~/src/styles/styles.css
file, as shown below:
@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-calendars/styles/material.css";
Add TimePicker to the application
Add the HTML input element for TimePicker to your index.html
.
[src/index.html]
<!DOCTYPE html>
<html lang="en">

<body>
<div style="margin: 20px 0px; width:250px">
<!--element to render the TimePicker-->
<input id="element"/>
</div>
</body>
</html>
Import the TimePicker component into your app.ts
and append it to the #element
[src/app/app.ts]
.
import { TimePicker } from '@syncfusion/ej2-calendars';
import { enableRipple } from '@syncfusion/ej2-base';
//enable ripple style
enableRipple(true);
// initialize timepicker component
let timeObject: TimePicker = new TimePicker({
placeholder: 'Select a Time'
});
// render initialized timepicker
timeObject.appendTo('#element');
Run the application
Use the following command to run the application in the browser.
npm run start
The following example shows a basic TimePicker.
import { TimePicker } from '@syncfusion/ej2-calendars';
import { enableRipple } from '@syncfusion/ej2-base';
//enable ripple style
enableRipple(true);
// creates the simple timepicker component
let timeObject: TimePicker = new TimePicker({
placeholder: 'Select a Time'
});
timeObject.appendTo('#element');

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. The TimePicker allows you to select the time value within a range from 7:00 AM
to 4:00 PM
.
import { TimePicker } from '@syncfusion/ej2-calendars';
import { enableRipple } from '@syncfusion/ej2-base';
//enable ripple style
enableRipple(true);
let month: number = new Date().getMonth();
let fullYear: number = new Date().getFullYear();
let date: number = new Date().getDate();
// creates timepicker with min max property
let timeObject: TimePicker = new TimePicker({
// Sets the min.
min: new Date(fullYear, month , date,7),
//Sets the max.
max: new Date(fullYear, month, date, 16),
// Sets the value.
value: new Date(fullYear, month , date, 13)
});
timeObject.appendTo('#element');

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.
import { TimePicker } from '@syncfusion/ej2-calendars';
import { enableRipple } from '@syncfusion/ej2-base';
//enable ripple style
enableRipple(true);
// creates the simple timepicker component
let timeObject: TimePicker = new TimePicker({
value: new Date(),
// sets the format property to display the time value in 24 hours format.
format: 'HH:mm',
// specify the interval value.
step: 60,
});
timeObject.appendTo('#element');

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