Overview

Smart.DateTimePicker represents a custom element which can be used to select and display date and time data.

Getting Started

Getting Started with DateTimePicker Web Component

Smart UI for Web Components is distributed as smart-webcomponents NPM package. You can also get the full download from our website with all demos from the Download page.

Setup the DateTimePicker

Smart UI for Web Components is distributed as smart-webcomponents NPM package

  1. Download and install the package.

    npm install smart-webcomponents

  2. Once installed, import the DateTimePicker module in your application.

    <script type="module" src="node_modules/smart-webcomponents/source/modules/smart.datetimepicker.js"></script>

  3. Adding CSS reference

    The smart.default.css CSS file should be referenced using following code.

    <link rel="stylesheet" type="text/css" href="node_modules/smart-webcomponents/source/styles/smart.default.css" />

  4. Add the DateTimePicker tag to your Web Page

    <smart-date-time-picker id="datetimepicker"></smart-date-time-picker>

  5. Create the DateTimePicker Component

    	<script type="module">
		Smart('#datetimepicker', class {
			get properties() {
				return { value: new Date(2020, 5, 11)}
			}
		});
	</script>

    Another option is to create the DateTimePicker is by using the traditional Javascript way:
    	const datetimepicker = document.createElement('smart-date-time-picker');

	datetimepicker.disabled = true;
	document.body.appendChild(datetimepicker);

    Smart framework provides a way to dynamically create a web component on demand from a DIV tag which is used as a host. The following imports the web component's module and creates it on demand, when the document is ready. The #datetimepicker is the ID of a DIV tag.

    	import "../../source/modules/smart.datetimepicker.js";

	document.readyState === 'complete' ? init() : window.onload = init;

	function init() { 
		const datetimepicker = new Smart.DateTimePicker('#datetimepicker', { value: new Date(2020, 5, 11)});
	}

  6. Open the page in your web server.

Appearance

By default Smart.DateTimePicker appears as a simple date time input. The user has to enable the popup button for the date/time picker, the navigation buttons and etc.

All available settings are listed in the API documentation of the element.

The date time picker can easily be transformed from a simple input into a drop down with date and time pickers. This can be done by simply applying a few properties:

<smart-date-time-picker calendar-button spin-buttons spin-buttons-position="left"></smart-date-time-picker>

Demo

The properties are self-describing:

  • calendar-button - enables the button for the drop down date/time picker.
  • spin-buttons - enables the buttons used to calibrate the date/time in the input.
  • spin-buttons-position - sets the position of the spin buttons.

Smart.DateTimePicker like the other Smart inputs has a label and a hint property. Positioned above and below the input field respectively, the fields that represent those properties serve as text lables that the user can modify to fit his needs. Here's how to apply them:

<smart-date-time-picker label="Date input:" hint="Calendar buttons is disabled"></smart-date-time-picker>

Demo

They can be changed after the element is ready using javascript.

Behavior

Smart.DateTimePicker can behave like a time picker, date picker or both.

dropDownDisplayMode property determines this behavior:

<smart-date-time-picker calendar-button drop-down-display-mode="timePicker" ></smart-date-time-picker>

Demo

The possible values are:

  • default - the drop down popup behaves like a tab control with two separate tabs: Date and Time.
  • classic - Time and Date pickers are combined into one in the drop down popup.
  • calendar - the drop down popup contains only a date picker - a Calendar.
  • timePicker - the drop down popup contains only a time picker - a TimePicker.

The user can edit the date or time directly in the input field. What part of the date/time can be edited depends on the editMode property. The user can prefer to edit fixed parts of the date/time string.

<smart-date-time-picker edit-mode="partial"></smart-date-time-picker>

Demo

Smart.DateTimePicker supports different date/time input formats.The formatString property determines the format of the date/time string. It can be changed in the HTML tag on initialization or later using javascript:

<!DOCTYPE html>
<html>
<head>
 <link rel="stylesheet" href="../../source/styles/smart.default.css" type="text/css" />
 <script type="text/javascript" src="../../source/smart.elements.js"></script>
 <script type="text/javascript">
     window.onload = function () {
         var dateTimePicker = document.getElementsByTagName('smart-date-time-picker')[0];
         //Default format
         dateTimePicker.formatString = 'dd-MMM-yy HH:mm:ss.fff';
         //Short date format
         dateTimePicker.formatString = 'd';
         //Custom date format
         dateTimePicker.formatString = 'dddd-MMMM-yyyy';
     }
 </script>
</head>
<body>
 <smart-date-time-picker></smart-date-time-picker>
</body>
</html>

Demo

The format of the date/time string can be standardized or custom.


Smart.DateTimePicker uses a Smart.Calendar as a date picker and Smart.TimePicker as a time picker.

Keyboard Support

Smart.DateTimePicker implements the following keys:

Key Action
Arrow Up / Arrow Down Increases/Decreases the selected date/time by one or moves the caret to the begining or the end ( depends on the editMode ).
Arrow Left / Arrow Right Navigate to the previous/next selection or moves the caret forward ( depends on the editMode ).
Home Selects the first item from the date/time input or sets the caret to the beggining ( depends on the editMode ).
End Selects the last item from the date/time input or sets the caret to the end ( depends on the editMode ).

Create, Append, Remove, Get/Set Property, Invoke Method, Bind to Event


Create a new element:
	const datetimepicker = document.createElement('smart-date-time-picker');

Append it to the DOM: 
	document.body.appendChild(datetimepicker);

Remove it from the DOM: 
	datetimepicker.parentNode.removeChild(datetimepicker);

Set a property: 
	datetimepicker.propertyName = propertyValue;

Get a property value: 
	const propertyValue = datetimepicker.propertyName;

Invoke a method: 
	datetimepicker.methodName(argument1, argument2);

Add Event Listener: 
	const eventHandler = (event) => {
	   // your code here.
	};

	datetimepicker.addEventListener(eventName, eventHandler);

Remove Event Listener: 
	datetimepicker.removeEventListener(eventName, eventHandler, true);

Using with Typescript

Smart Web Components package includes TypeScript definitions which enables strongly-typed access to the Smart UI Components and their configuration.

Inside the download package, the typescript directory contains .d.ts file for each web component and a smart.elements.d.ts typescript definitions file for all web components. Copy the typescript definitions file to your project and in your TypeScript file add a reference to smart.elements.d.ts

Getting Started with Angular DateTimePicker Component

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 smart-angular-datetimepicker

Navigate to the created project folder 

cd smart-angular-datetimepicker

Setup the DateTimePicker

Smart UI for Angular is distributed as smart-webcomponents-angular NPM package

  1. Download and install the package.
    npm install smart-webcomponents-angular
  2. Once installed, import the DateTimePickerModule in your application root or feature module.

    app.module.ts

    import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';

import { DateTimePickerModule } from 'smart-webcomponents-angular/datetimepicker';

import { AppComponent } from './app.component';

@NgModule({
    declarations: [ AppComponent ],
    imports: [ BrowserModule, DateTimePickerModule ],
    bootstrap: [ AppComponent ],
	entryComponents: [ AppComponent ]
})

export class AppModule { }

  3. Adding CSS reference

    The following CSS file is available in ../node_modules/smart-webcomponents-angular/ package folder. This can be referenced in [src/styles.css] using following code. 

    	@import 'smart-webcomponents-angular/source/styles/smart.default.css';

    Another way to achieve the same is to edit the angular.json file and in the styles add the style. 

    	"styles": [
		"node_modules/smart-webcomponents-angular/source/styles/smart.default.css"
	]
  4. Example


    app.component.html

     
<smart-date-time-picker #datetimepicker [calendarButton]="true" [enableMouseWheelAction]="true"
                        [dropDownPosition]="'center-bottom'" [spinButtons]="true" [spinButtonsPosition]="'left'"></smart-date-time-picker>

    app.component.ts

     
import { Component, ViewChild, OnInit, AfterViewInit } from '@angular/core';
import { DateTimePickerComponent } from 'smart-webcomponents-angular/datetimepicker';


@Component({
    selector: 'app-root',
    templateUrl: './app.component.html',
	styleUrls: ['./app.component.css']
})

export class AppComponent implements AfterViewInit, OnInit {	
	@ViewChild('datetimepicker', { read: DateTimePickerComponent, static: false }) datetimepicker!: DateTimePickerComponent;
	
 
	ngOnInit(): void {
		// onInit code.
	}

	ngAfterViewInit(): void {
		// afterViewInit code.
		this.init();
    }
		
	init(): void {
		// init code.
	    

	}	
}

    app.module.ts

     
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';

import { DateTimePickerModule } from 'smart-webcomponents-angular/datetimepicker';

import { AppComponent } from './app.component';

@NgModule({
    declarations: [ AppComponent ],
    imports: [ BrowserModule, DateTimePickerModule ],
    bootstrap: [ AppComponent ],
	entryComponents: [ AppComponent ]
})

export class AppModule { }


Running the Angular application

After completing the steps required to render a DateTimePicker, run the following command to display the output in your web browser

ng serve
and open localhost:4200 in your favorite web browser.

Getting Started with React DateTimePicker Component

Setup React Environment

The easiest way to start with React is to use create-react-app. To scaffold your project structure, follow the installation instructions.

npx create-react-app my-app
cd my-app
npm start

Preparation

Open src/App.js andsrc/App.css

  1. Remove everything inside the App div tag in src/App.js: 
    <div className="App"> </div>
  2. Remove the logo.svg import
  3. Remove the contents of src/App.css
  4. Remove src/logo.svg

Setup the DateTimePicker

Smart UI for React is distributed as smart-webcomponents-react NPM package

  1. Download and install the package.
    npm install smart-webcomponents-react
    2. Once installed, import the React DateTimePicker Component and CSS files in your application and render it app.js

    import 'smart-webcomponents-react/source/styles/smart.default.css';
import React from "react";
import ReactDOM from 'react-dom/client';
import { DateTimePicker } from 'smart-webcomponents-react/datetimepicker';

const App = () => {
	return (
		<div>
			<DateTimePicker calendarButton enableMouseWheelAction
				dropDownPosition="center-bottom" spinButtons spinButtonsPosition="left"></DateTimePicker>
		</div>
	);
}



export default App;

Running the React application

Start the app with 
npm start
and open localhost:3000 in your favorite web browser to see the output.

Getting Started with Vue DateTimePicker Component


Setup Vue Environment

We will use vue-cli to get started. Let's install vue-cli

npm install -g @vue/cli

Then we can start creating our Vue.js projects with:

vue create my-project

Setup the DateTimePicker

Open the "my-project" folder and run:

npm install smart-webcomponents

Setup with Vue 3.x

  • Make Vue ignore custom elements defined outside of Vue (e.g., using the Web Components APIs). Otherwise, it will throw a warning about an Unknown custom element, assuming that you forgot to register a global component or misspelled a component name.

    Open src/main.js in your favorite text editor and change its contents to the following:

    main.js

    import { createApp } from 'vue'
import App from './App.vue'

const app = createApp(App)

app.config.isCustomElement = tag => tag.startsWith('smart-');
app.mount('#app')
  • Open src/App.vue in your favorite text editor and change its contents to the following:

    App.vue 

    <template>
  <div class="vue-root">
    <smart-date-time-picker
      calendar-button
      enable-mouse-wheel-action
      drop-down-position="center-bottom"
      spin-buttons
      spin-buttons-position="left"
    ></smart-date-time-picker>
  </div>
</template>

<script>
import { onMounted } from "vue";
import "smart-webcomponents/source/styles/smart.default.css";
import "smart-webcomponents/source/modules/smart.datetimepicker.js";

export default {
  name: "app",
  setup() {
    onMounted(() => {});
  }
};
</script>

<style>
@media only screen and (max-width: 500px) {
  .smart-drop-down.smart-date-time-drop-down {
    left: 70%;
  }
}
</style>
    We can now use the smart-date-time-picker with Vue 3. Data binding and event handlers will just work right out of the box.

Setup with Vue 2.x

  • Make Vue ignore custom elements defined outside of Vue (e.g., using the Web Components APIs). Otherwise, it will throw a warning about an Unknown custom element, assuming that you forgot to register a global component or misspelled a component name.

    Open src/main.js in your favorite text editor and change its contents to the following:

    main.js

    import Vue from 'vue'
import App from './App.vue'

Vue.config.productionTip = false
Vue.config.ignoredElements = [
'smart-date-time-picker'
]

new Vue({
  render: h => h(App),
}).$mount('#app')
  • Open src/App.vue in your favorite text editor and change its contents to the following:

    App.vue 

    <template>
   <smart-date-time-picker calendar-button enable-mouse-wheel-action drop-down-position="center-bottom" spin-buttons spin-buttons-position="left"></smart-date-time-picker>
</template> 

<script>
import 'smart-webcomponents/source/modules/smart.datetimepicker.js';
import "smart-webcomponents/source/styles/smart.default.css";

export default {
  name: "app"
};
</script>

<style>
@media only screen and (max-width: 500px) {  
	.smart-drop-down.smart-date-time-drop-down {
		left: 70%;
	}
}
</style>
    We can now use the smart-date-time-picker with Vue. Data binding and event handlers will just work right out of the box.
    We have bound the properties of the smart-date-time-picker to values in our Vue component.

Running the Vue application

Start the app with 
npm run serve
and open localhost:8080 in your favorite web browser to see the output below:
