Overview

Smart.Button represents a simple button that can be clicked.

Getting Started with Button 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 Button

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 Button module in your application.

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

    <smart-button id="button"></smart-button>

  5. Create the Button Component

    	<script type="module">
    		Smart('#button', class {
    			get properties() {
    				return {"type":"submit"}
    			}
    		});
    	</script>	   
    		

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

    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 #button is the ID of a DIV tag.

    	import "../../source/modules/smart.button.js";
    
    	document.readyState === 'complete' ? init() : window.onload = init;
    
    	function init() { 
    		const button = new Smart.Button('#button', {"type":"submit"});
    	}
    	

  6. Open the page in your web server.

The following code adds a simple button to the page.

<!DOCTYPE html>
<html lang="en">
<head>
 <link rel="stylesheet" href="../../source/styles/smart.default.css" type="text/css" />
</head>
<body>
 <smart-button>Click me</smart-button>
 <script type="module" src="../../source/modules/smart.button.js"></script>
</body>
</html>

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

Demo

Appearance

If the user wants to change the content of the button, this can be accomplished by setting the innerHTML property of the element, like so:

<!DOCTYPE html>
<html lang="en">
<head>
 <link rel="stylesheet" href="../../source/styles/smart.default.css" type="text/css" />
 <script>
     window.onload = function () {
        document.querySelector('smart-button').innerHTML = 'Button 1';
     }
 </script>
</head>
<body>
 <smart-button>Click Me</smart-button>
 <script type="module" src="../../source/modules/smart.button.js"></script>
</body>
</html>

Using the innerHTML property the user can change the content of the element dynamically as well.

Demo

Behavior

By default the innerHTML of the button is an empty string.

The element offers multiple click modes:

  • hover
  • press
  • release
  • pressAndRelease

clickMode is a property of the button that can be changed either from the HTML tag by setting the attribute click-mode and assigning a new value to it or by following the earlier approach and change it dynamically via javascript during the onload stage of the window object or later.

Here's how to set a new click mode on element initialization:

<!DOCTYPE html>
<html lang="en">
<head>
 <link rel="stylesheet" href="../../source/styles/smart.default.css" type="text/css" />
</head>
<body>
 <smart-button click-mode="release">Click Me</smart-button>
 <script type="module" src="../../source/modules/smart.button.js"></script>
</body>
</html>

Demo

And here's how to change it via javascript after the element has been initialized:

<!DOCTYPE html>
<html lang="en">
<head>
 <link rel="stylesheet" href="../../source/styles/smart.default.css" type="text/css" />
 <script>
 window.onload = function () {
    document.querySelector('smart-button').clickMode = 'pressAndRelease';
 }
 </script>
</head>
<body>
 <smart-button>Click Me</smart-button>
 <script type="module" src="../../source/modules/smart.button.js"></script>
</body>
</html>

Demo

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


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

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

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

Set a property:
	button.propertyName = propertyValue;
	

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

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

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

	button.addEventListener(eventName, eventHandler);
	

Remove Event Listener:
	button.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 Button 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-button

Navigate to the created project folder

cd smart-angular-button

Setup the Button

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 ButtonModule in your application root or feature module.

    app.module.ts

    import { NgModule } from '@angular/core';
    import { BrowserModule } from '@angular/platform-browser';
    
    import { ButtonModule } from 'smart-webcomponents-angular/button';
    
    import { AppComponent } from './app.component';
    
    @NgModule({
        declarations: [ AppComponent ],
        imports: [ BrowserModule, ButtonModule ],
        bootstrap: [ 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

     
    <div class="demo-horizontal-layout">
        <div>
            <label>Default Buttons</label>

Getting Started with React Button 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 Button

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 Button 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 { Button, RepeatButton, ToggleButton, PowerButton } from 'smart-webcomponents-react/button';
    
    class App extends React.Component {
    
    	componentDidMount() {
    
    	}
    
    	render() {
    		return (
    			<div>

Getting Started with Vue Button 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 Button

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">
        <div class="demo-horizontal-layout">
          <div>
            <label>Default Buttons</label>
            <div class="demo-buttons-group">
              <smart-button>Normal</smart-button>
              <smart-button class="raised">Raised</smart-button>
              <smart-button class="outlined">Outlined</smart-button>
              <smart-button class="flat">Flat</smart-button>
              <smart-button class="floating">
                <span
                  class="button-demo-icon demo-icon demo-device-icon-phone-portrait demo-button-demo-icon"
                >
                  <i class="material-icons">&#xE53F;</i>
                </span>
              </smart-button>
            </div>
          </div>
          <div>
            <label>Primary Buttons</label>
            <div class="demo-buttons-group">
              <smart-button class="primary">Normal</smart-button>
              <smart-button class="raised primary">Raised</smart-button>
              <smart-button class="outlined primary">Outlined</smart-button>
              <smart-button class="flat primary">Flat</smart-button>
              <smart-button class="floating primary">
                <span

                >
                  <i class="material-icons">&#xE53F;</i>
                </span>
              </smart-button>

          <div>
            <label>Secondary Buttons</label>
            <div class="demo-buttons-group">
              <smart-button class="secondary">Normal</smart-button>

    We can now use the smart-button 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-button'
    ]
    
    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>
      <div class="demo-horizontal-layout">

    We can now use the smart-button with Vue. Data binding and event handlers will just work right out of the box.
    We have bound the properties of the smart-button 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:

Keyboard Support

Smart.Button follows HTML button's keyboard navigation behavior. This means that the button can be selected using Space. The element is focusable and can be focused using the Tab button.
