npm install -g @angular/cli

Create a new application

Copied to clipboard
ng new syncfusion-angular-timepicker

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

Example code snippet.

cd syncfusion-angular-timepicker

Adding TimePicker package

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

To install TimePicker component, use the following command.

Copied to clipboard
npm install @syncfusion/ej2-angular-calendars --save
(or)
npm I @syncfusion/ej2-angular-calendars --save

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

Registering TimePicker module

Import TimePicker module into Angular application(src/app/app.module.ts) from the package @syncfusion/ej2-angular-calendars.

Copied to clipboard
import { NgModule }      from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
// import the TimePickerModule for the TimePicker component
import { TimePickerModule } from '@syncfusion/ej2-angular-calendars';
import { AppComponent }  from './app.component';

@NgModule({
  //declaration of TimePickerModule into NgModule
  imports:      [ BrowserModule, TimePickerModule ],
  declarations: [ AppComponent ],
  bootstrap:    [ AppComponent ]
})
export class AppModule { }

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.

Copied to clipboard
@import '../node_modules/@syncfusion/ej2-base/styles/material.css';
@import '../node_modules/@syncfusion/ej2-buttons/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-splitbuttons/styles/material.css';
@import '../node_modules/@syncfusion/ej2-calendars/styles/material.css';
@import '../node_modules/@syncfusion/ej2-angular-calendars/styles/material.css';

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

Adding TimePicker component

Modify the template in [src/app/app.component.ts] file to render the TimePicker component. Add the Angular TimePicker by using <ejs-timepicker> selector in template section of the app.component.ts file.

import { Component } from '@angular/core';
import { enableRipple } from '@syncfusion/ej2-base';

//enable ripple style
enableRipple(true);

@Component({
  selector: 'app-root',
  template: `<!-- To Render TimePicker -->
             <ejs-timepicker></ejs-timepicker>`
})
export class AppComponent  { }

Running the application

After completing the configuration required to render a basic TimePicker, run the following command to display the output in your default browser.

ng serve

The following example illustrates the output in your browser

Setting the selected, 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.

        <ejs-timepicker [value]='dateValue' [min]='minValue' [max]='maxValue'></ejs-timepicker>
        `
})

export class AppComponent {
    public month: number = new Date().getMonth();
    public fullYear: number = new Date().getFullYear();
    public date: number = new Date().getDate();
    public dateValue: Date = new Date(this.fullYear, this.month , this.date, 10, 0, 0);
    public minValue: Date = new Date(this.fullYear, this.month , this.date, 7, 0, 0);
    public maxValue: Date = new Date(this.fullYear, this.month, this.date, 16, 0 ,0);
    constructor() {
    }

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

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 { Component } from '@angular/core';
import { enableRipple } from '@syncfusion/ej2-base';

@Component({
    selector: 'app-root',
    template: `
        <ejs-timepicker [placeholder]='watermark' [format]='formatString' [step]='interval' ></ejs-timepicker>
        `
})

export class AppComponent {
    public watermark: string = 'Select a time';
    // sets the format property to display the time value in 24 hours format.
    public formatString: string = 'HH:mm';
    public interval: number = 60;
    constructor() {
    }
}

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { TimePickerModule } from '@syncfusion/ej2-angular-calendars';
import { AppComponent } from './app.component';


/**

@NgModule({
    imports: [
        BrowserModule,
        TimePickerModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent]
})
export class AppModule { }
Copied to clipboard
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

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