TimePicker - Documentation | www.HtmlElements.com

Overview

Smart.TimePicker represents an element used for selection of time (hours and minutes).

Getting Started with TimePicker 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 TimePicker

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 TimePicker module in your application.

    <script type="module" src="node_modules/smart-webcomponents/source/modules/smart.timepicker.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 TimePicker tag to your Web Page

    <smart-time-picker id="timepicker"></smart-time-picker>

  5. Create the TimePicker Component

    	<script type="module">
    		Smart('#timepicker', class {
    			get properties() {
    				return { format: "24-hour" }
    			}
    		});
    	</script>	   
    		

    Another option is to create the TimePicker is by using the traditional Javascript way:
    	const timepicker = document.createElement('smart-time-picker');
    
    	timepicker.disabled = true;
    	document.body.appendChild(timepicker);
    		

    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 #timepicker is the ID of a DIV tag.

    	import "../../source/modules/smart.timepicker.js";
    
    	document.readyState === 'complete' ? init() : window.onload = init;
    
    	function init() { 
    		const timepicker = new Smart.TimePicker('#timepicker', { format: "24-hour" });
    	}
    	

  6. Open the page in your web server.
Load scripts

The following code adds the custom element to the page.

<!DOCTYPE html>
<html>
<head>
 <link rel="stylesheet" href="../../source/styles/smart.default.css" type="text/css" />
 <script type="text/javascript" src="../../source/smart.element.js"></script>
 <script type="text/javascript" src="../../source/smart.numeric.js"></script>
 <script type="text/javascript" src="../../source/smart.math.js"></script>
 <script type="text/javascript" src="../../source/smart.draw.js"></script>
 <script type="text/javascript" src="../../source/smart.timepicker.js"></script>
</head>
<body>
 <smart-time-picker></smart-time-picker>
</body>
</html>

Note how smart.element.js is declared before everything else. This is mandatory for all custom elements.

Demo

Smart.TimePicker accepts javascript Date objects as time values. The value property is responsible for the time value of the element. Like every custom element property it can be set as an attribute inside the HTML tag of the element:

<smart-time-picker value="new Date(2017,12,1,12,25)"></smart-time-picker>

Demo

or 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.element.js"></script>
 <script type="text/javascript" src="../../source/smart.numeric.js"></script>
 <script type="text/javascript" src="../../source/smart.math.js"></script>
 <script type="text/javascript" src="../../source/smart.draw.js"></script>
 <script type="text/javascript" src="../../source/smart.timepicker.js"></script>
 <script>
     window.onload = function () {
        document.querySelector('smart-time-picker').value = new Date(2017, 12, 1, 15, 24, 0);
     }
 </script>
</head>
<body>
 <smart-time-picker></smart-time-picker>
</body>
</html>

Demo

Appearance

Smart.TimePicker supoprts 12 and 24 hour time format. By default the element uses 12 hour format but the user can change that via the format property like so:

<smart-time-picker format="24-hour"></smart-time-picker>

Demo


The time picker has two orientation modes that can be changed using the view property. The possible values are:

  • landscape - horizontally positioned
  • portrait - vertically positioned. Default value.

The property can be set as HTML attribute:

<smart-time-picker view="landscape"></smart-time-picker>

Demo

or javascript:

<!DOCTYPE html>
<html>
<head>
 <link rel="stylesheet" href="../../source/styles/smart.default.css" type="text/css" />
 <script type="text/javascript" src="../../source/smart.element.js"></script>
 <script type="text/javascript" src="../../source/smart.numeric.js"></script>
 <script type="text/javascript" src="../../source/smart.math.js"></script>
 <script type="text/javascript" src="../../source/smart.draw.js"></script>
 <script type="text/javascript" src="../../source/smart.timepicker.js"></script>
 <script>
     window.onload = function () {
        document.querySelector('smart-time-picker').view = 'landscape';
     }
 </script>
</head>
<body>
 <smart-time-picker></smart-time-picker>
</body>
</html>

Demo


The element has a footer section that is hidden by default. The visibility of the section is controlled by the footer property. The contneto of the footer can be customized using an HTML Template. Here's how to enable the footer and place HTML content inside:

<!DOCTYPE html>
<html>
<head>
 <link rel="stylesheet" href="../../source/styles/smart.default.css" type="text/css" />
 <script type="text/javascript" src="../../source/smart.element.js"></script>
 <script type="text/javascript" src="../../source/smart.button.js"></script>
 <script type="text/javascript" src="../../source/smart.numeric.js"></script>
 <script type="text/javascript" src="../../source/smart.math.js"></script>
 <script type="text/javascript" src="../../source/smart.draw.js"></script>
 <script type="text/javascript" src="../../source/smart.timepicker.js"></script>
</head>
<body>
 <template id="footerTemplate">
     <smart-button>Close</smart-button>
     <smart-button>Ok</smart-button>
 </template>
 <smart-time-picker footer footer-template="footerTemplate"></smart-time-picker>
</body>
</html>

Demo

The same can be accomplished via javascript:

<!DOCTYPE html>
<html>
<head>
 <link rel="stylesheet" href="../../source/styles/smart.default.css" type="text/css" />
 <script type="text/javascript" src="../../source/smart.element.js"></script>
 <script type="text/javascript" src="../../source/smart.button.js"></script>
 <script type="text/javascript" src="../../source/smart.numeric.js"></script>
 <script type="text/javascript" src="../../source/smart.math.js"></script>
 <script type="text/javascript" src="../../source/smart.draw.js"></script>
 <script type="text/javascript" src="../../source/smart.timepicker.js"></script>
 <script>
     window.onload = function () {
         var timePicker = document.querySelector('smart-time-picker');
 
         timePicker.footerTemplate = 'footerTemplate';
         timePicker.footer = true;
     }
 </script>
</head>
<body>
 <template id="footerTemplate">
     <smart-button>Close</smart-button>
     <smart-button>Ok</smart-button>
 </template>
 <smart-time-picker></smart-time-picker>
</body>
</html>

Demo

Behavior

Time selection is devided into hour selection and minute selection and the user can switch between the views by clicking on the appropriate part of the time string. However the user can enable the autoSwitchToMinutes property which redirects the user to the minute selection view after selecting an hour.

<smart-time-picker auto-switch-to-minutes></smart-time-picker>

Demo

The selection view can also be controlled via the selection property. The available options are:

  • hour - hour selection.
  • minute - minute selection.

The view can be changed at any time using javascript or applied on HTML initialization:

<smart-time-picker selection="minute"></smart-time-picker>

Demo


The user can also change the minute interval. This can be accomplished by applying the new minute interval in numeric format to the minuteInterval property.

<smart-time-picker selection="minute" minute-interval="15"></smart-time-picker>

Demo

Styling

Styling Smart.TimePicker is done exclusively trough CSS class selectors.

<!DOCTYPE html>
<html>
<head>
 <link rel="stylesheet" href="../../source/styles/smart.default.css" type="text/css" />
 <script type="text/javascript" src="../../source/smart.element.js"></script>
 <script type="text/javascript" src="../../source/smart.numeric.js"></script>
 <script type="text/javascript" src="../../source/smart.math.js"></script>
 <script type="text/javascript" src="../../source/smart.draw.js"></script>
 <script type="text/javascript" src="../../source/smart.timepicker.js"></script>
 <style>
     smart-time-picker {
         width: 150px;
         height: 300px;
     }
     smart-time-picker .smart-main-container {
        background-color: #EEEEEE;
     }
 </style>
</head>
<body>
 <smart-time-picker></smart-time-picker>
</body>
</html>

Demo

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


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

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

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

Set a property:
	timepicker.propertyName = propertyValue;
	

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

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

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

	timepicker.addEventListener(eventName, eventHandler);
	

Remove Event Listener:
	timepicker.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 TimePicker 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-timepicker

Navigate to the created project folder

cd smart-angular-timepicker

Setup the TimePicker

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

  1. Download and install the package.
    npm install smart-webcomponents-angular
  2. 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"
    	]
    If you want to use Bootstrap, Fluent or other themes available in the package, you need to add them after 'smart.default.css'.
  3. Example with Angular Standalone Components


    app.component.html

     <smart-time-picker #timepicker></smart-time-picker>

    app.component.ts

     import { Component, ViewChild, OnInit, AfterViewInit } from '@angular/core';
    import { TimePickerComponent } from 'smart-webcomponents-angular/timepicker';
    
    import { CommonModule } from '@angular/common';
    import { RouterOutlet } from '@angular/router';
    import { TimePickerModule } from 'smart-webcomponents-angular/timepicker';
    
    @Component({
        selector: 'app-root',
    	standalone: true,
    	imports: [CommonModule, TimePickerModule, RouterOutlet],
        templateUrl: './app.component.html',
        styleUrls: ['./app.component.css']
    })
    
    export class AppComponent implements AfterViewInit, OnInit {
        @ViewChild('timepicker', { read: TimePickerComponent, static: false }) timepicker!: TimePickerComponent;
    
    
        ngOnInit(): void {
            // onInit code.
        }
    
        ngAfterViewInit(): void {
            // afterViewInit code.
            this.init();
        }
    
        init(): void {
            // init code.
    
    
        }
    }

  4. Example with Angular NGModule


    app.component.html

     <smart-time-picker #timepicker></smart-time-picker>

    app.component.ts

     import { Component, ViewChild, OnInit, AfterViewInit } from '@angular/core';
    import { TimePickerComponent } from 'smart-webcomponents-angular/timepicker';
    
    @Component({
        selector: 'app-root',
        templateUrl: './app.component.html',
        styleUrls: ['./app.component.css']
    })
    
    export class AppComponent implements AfterViewInit, OnInit {
        @ViewChild('timepicker', { read: TimePickerComponent, static: false }) timepicker!: TimePickerComponent;
    
    
        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 { TimePickerModule } from 'smart-webcomponents-angular/timepicker';
    
    import { AppComponent } from './app.component';
    
    @NgModule({
        declarations: [AppComponent],
        imports: [BrowserModule, TimePickerModule],
        bootstrap: [AppComponent]
    })
    
    export class AppModule { }

Getting Started with Vue TimePicker Component


Setup Vue with Vite

In this section we will introduce how to scaffold a Vue Single Page Application on your local machine. The created project will be using a build setup based on Vite and allow us to use Vue Single-File Components (SFCs). Run the following command in your command line
npm create vue@latest
This command will install and execute create-vue, the official Vue project scaffolding tool. You will be presented with prompts for several optional features such as TypeScript and testing support:
✔ Project name: … 
✔ Add TypeScript? … No / Yes
✔ Add JSX Support? … No / Yes
✔ Add Vue Router for Single Page Application development? … No / Yes
✔ Add Pinia for state management? … No / Yes
✔ Add Vitest for Unit testing? … No / Yes
✔ Add an End-to-End Testing Solution? … No / Cypress / Playwright
✔ Add ESLint for code quality? … No / Yes
✔ Add Prettier for code formatting? … No / Yes

Scaffolding project in ./...
Done.
If you are unsure about an option, simply choose No by hitting enter for now. Once the project is created, follow the instructions to install dependencies and start the dev server:
cd 
npm install
npm install smart-webcomponents
npm run dev
  • 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 vite.config.js in your favorite text editor and change its contents to the following:

    vite.config.js

    import { fileURLToPath, URL } from 'node:url'
    
    import { defineConfig } from 'vite'
    import vue from '@vitejs/plugin-vue'
    
    // https://vitejs.dev/config/
    export default defineConfig({
      plugins: [
        vue({
          template: {
            compilerOptions: {
              isCustomElement: tag => tag.startsWith('smart-')
            }
          }
        })
      ],
      resolve: {
        alias: {
          '@': fileURLToPath(new URL('./src', import.meta.url))
        }
      }
    })
    		
  • Open src/App.vue in your favorite text editor and change its contents to the following:

    App.vue

    <template>
      <div class="vue-root">
        <smart-time-picker></smart-time-picker>
      </div>
    </template>
    
    <script>
    import { onMounted } from "vue";
    import "smart-webcomponents/source/styles/smart.default.css";
    import "smart-webcomponents/source/modules/smart.timepicker.js";
    
    export default {
      name: "app",
      setup() {
        onMounted(() => {});
      }
    };
    </script>
    
    <style>
    </style>
    		
    We can now use the smart-time-picker with Vue 3. Data binding and event handlers will just work right out of the box.

Running the Vue application

Start the app with
npm run dev
and open http://localhost:5173/ in your favorite web browser to see the output below:
When you are ready to ship your app to production, run the following:
npm run build
This will create a production-ready build of your app in the project's ./dist directory.
