Getting Started

Getting Started with PasswordTextBox 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 PasswordTextBox

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 PasswordTextBox module in your application.

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

    <smart-password-text-box id="passwordtextbox"></smart-password-text-box>

  5. Create the PasswordTextBox Component

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

    Another option is to create the PasswordTextBox is by using the traditional Javascript way:
    	const passwordtextbox = document.createElement('smart-password-text-box');

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

    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 #passwordtextbox is the ID of a DIV tag.

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

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

	function init() { 
		const passwordtextbox = new Smart.PasswordTextBox('#passwordtextbox', { disabled: true });
	}

  6. Open the page in your web server.

Appearance

The user can see and check it's password via clicking an icon when showPasswordIcon is true. This icon is displayed when the element is focussed.

<!DOCTYPE html>
<html lang="en">
<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.scrollbar.js"></script>
 <script type="text/javascript" src="../../source/smart.listbox.js"></script>
 <script type="text/javascript" src="../../source/smart.textbox.js"></script>
 <script type="text/javascript" src="../../source/smart.tooltip.js"></script>
 <script type="text/javascript" src="../../source/smart.passwordtextbox.js"></script>
 <script>
 window.onload = function () {
    document.querySelector('smart-password-text-box').showPasswordIcon = true;
 }
 </script>
</head>
<body>
 <smart-password-text-box></smart-password-text-box>
</body>
</html>

Demo

The password strength could be visualized via tooltip and border color change. The property allowed this is showPasswordStrength.

 <smart-password-text-box show-password-strength></smart-password-text-box>

Demo

The password strength tooltip could be with arrow when tooltipArrow is true. By default it's false

 <smart-password-text-box show-password-strength tooltip-arrow></smart-password-text-box>

Demo

The password strength tooltip could be positioned in few different positions.

  • top
  • right
  • bottom
  • left
  • absolute - tooltip is absolute positioned on left and top position
 <smart-password-text-box show-password-strength tooltip-arrow tooltip-position="left"></smart-password-text-box>

Demo

Behavior

The user can controll the password strength response via passwordStrength callback.

Here's how to set passwordStrength callback:

<!DOCTYPE html>
<html lang="en">
<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.scrollbar.js"></script>
 <script type="text/javascript" src="../../source/smart.listbox.js"></script>
 <script type="text/javascript" src="../../source/smart.textbox.js"></script>
 <script type="text/javascript" src="../../source/smart.tooltip.js"></script>
 <script type="text/javascript" src="../../source/smart.passwordtextbox.js"></script>
 <script>
 window.onload = function () {
    document.querySelector('smart-password-text-box').passwordStrength = function (password, allowedSymbols) {
        const passwordLength = password.length;
        if (passwordLength < 3) {
            return 'short' ;
        } else if (passwordLength < 10) {
            return 'weak';
        } else {
            return 'strong';
        }
   };
 }
 </script>
</head>
<body>
 <smart-password-text-box show-password-strength tooltip-arrow tooltip-position="left"></smart-password-text-box>
</body>
</html>

Demo

Keyboard Support

The element is focusable and can be focused using the Tab button.

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


Create a new element:
	const passwordtextbox = document.createElement('smart-password-text-box');

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

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

Set a property: 
	passwordtextbox.propertyName = propertyValue;

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

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

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

	passwordtextbox.addEventListener(eventName, eventHandler);

Remove Event Listener: 
	passwordtextbox.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 PasswordTextBox 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-passwordtextbox

Navigate to the created project folder 

cd smart-angular-passwordtextbox

Setup the PasswordTextBox

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 PasswordTextBoxModule in your application root or feature module.

    app.module.ts

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

import { PasswordTextBoxModule } from 'smart-webcomponents-angular/passwordtextbox';

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

@NgModule({
    declarations: [ AppComponent ],
    imports: [ BrowserModule, PasswordTextBoxModule ],
    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-description">Simple password field.</div>
<smart-password-text-box #passwordtextbox [placeholder]="'Your password'"></smart-password-text-box>

    app.component.ts

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


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

export class AppComponent implements AfterViewInit, OnInit {	
	@ViewChild('passwordtextbox', { read: PasswordTextBoxComponent, static: false }) passwordtextbox!: PasswordTextBoxComponent;
	
 
	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 { PasswordTextBoxModule } from 'smart-webcomponents-angular/passwordtextbox';

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

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

export class AppModule { }


Running the Angular application

After completing the steps required to render a PasswordTextBox, 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 PasswordTextBox 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 PasswordTextBox

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 PasswordTextBox 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 { PasswordTextBox } from 'smart-webcomponents-react/passwordtextbox';

class App extends React.Component {

	init() {
	
	}


	componentDidMount() {

	}

	render() {
		return (
			<div>
			    <div className="demo-description">Simple password field.</div>
			    <PasswordTextBox placeholder="Your password"></PasswordTextBox>
			</div>
		);
	}
}



export default App;

Getting Started with Vue PasswordTextBox 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 PasswordTextBox

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-description">Simple password field.</div>
    <smart-password-text-box class="outlined" placeholder></smart-password-text-box>
  </div>
</template>

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

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

<style>
</style>
    We can now use the smart-password-text-box 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-password-text-box'
]

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-password-text-box placeholder="Your password"></smart-password-text-box>
</template> 

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

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

<style>
</style>
    We can now use the smart-password-text-box with Vue. Data binding and event handlers will just work right out of the box.
    We have bound the properties of the smart-password-text-box 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:
