Overview

Smart.TextBox element represents single row editable text box, supported two different display modes.

Getting Started with TextBox 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 TextBox

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 TextBox module in your application.

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

    <smart-text-box id="textbox"></smart-text-box>

  5. Create the TextBox Component

    	<script type="module">
    		Smart('#textbox', class {
    			get properties() {
    				return { placeholder: "Enter First Name"}
    			}
    		});
    	</script>	   
    		

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

    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 #textbox is the ID of a DIV tag.

    	import "../../source/modules/smart.textbox.js";
    
    	document.readyState === 'complete' ? init() : window.onload = init;
    
    	function init() { 
    		const textbox = new Smart.TextBox('#textbox', { placeholder: "Enter First Name"});
    	}
    	

  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" />
cript 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.dropdownlist.js"></script>
 <script type="text/javascript" src="../../source/smart.combobox.js"></script>
 <script type="text/javascript" src="../../source/smart.textbox.js"></script>
</head>
<body>
 <smart-text-box></smart-text-box>
</body>
</html>

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

Demo

Appearance

If the user wants to change the content of the text box, this can be accomplished by setting the value 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 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.dropdownlist.js"></script>
 <script type="text/javascript" src="../../source/smart.textbox.js"></script>
 <script>
 window.onload = function () {
    document.querySelector('smart-text-box').value = 'Text Box New Value';
 }
 </script>
</head>
<body>
 <smart-text-box>Check Box</smart-text-box>
</body>
</html>

Demo

Behavior

smart-text-box has two display modes:

  • default - the element behaves like a regular input
  • escaped - the element behaves like an input, but all special characters are escaped

Here's how to set a new displayMode on element's initialiation:

<!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.dropdownlist.js"></script>
 <script type="text/javascript" src="../../source/smart.textbox.js"></script>
</head>
<body>
 <smart-text-box display-mode="escaped"></smart-text-box>
</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 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.dropdownlist.js"></script>
 <script type="text/javascript" src="../../source/smart.textbox.js"></script>
 <script>
 window.onload = function () {
    document.querySelector('smart-text-box').displayMode = 'escaped';
 }
 </script>
</head>
<body>
 <smart-text-box></smart-text-box>
</body>
</html>

Demo

In displayMode:default the element could have autocomplete functionality - drop down with suggestions, based on the current user input. The drop down with options is based in the values in element's dataSource. Autocomplete options are:

  • none - autocomplete option is disabled
  • manual - the character string the user has typed will become the value of the textbox unless the user selects a value in the popup
  • auto - the automatically selected suggestion becomes the value of the textbox when the combobox loses focus unless the user chooses a different suggestion or changes the character string in the textbox
  • inline - the inline completion string is visually highlighted and has a selected state

In addition the user can set new value about minLength. By default it's 2. minLength sets the minimum number of characters that the user have to enter to trigger the autocomplete popup.

 <smart-text-box data-source='["item 1", "item 2"]' autocomplete="manual" min-length="1"></smart-text-box>

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


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

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

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

Set a property:
	textbox.propertyName = propertyValue;
	

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

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

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

	textbox.addEventListener(eventName, eventHandler);
	

Remove Event Listener:
	textbox.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 TextBox 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-textbox

Navigate to the created project folder

cd smart-angular-textbox

Setup the TextBox

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 TextBoxModule in your application root or feature module.

    app.module.ts

    import { NgModule } from '@angular/core';
    import { BrowserModule } from '@angular/platform-browser';
    
    import { TextBoxModule } from 'smart-webcomponents-angular/textbox';
    
    import { AppComponent } from './app.component';
    
    @NgModule({
        declarations: [ AppComponent ],
        imports: [ BrowserModule, TextBoxModule ],
        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-text-box #textbox [selectAllOnFocus]="true" [placeholder]="'smart Text Box'"></smart-text-box>
    		

    app.component.ts

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


Running the Angular application

After completing the steps required to render a TextBox, 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 TextBox 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.

	npm install -g create-react-app
	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 TextBox

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 TextBox 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";
    import { TextBox, ListItem, ListItemsGroup } from 'smart-webcomponents-react/textbox';
    
    class App extends React.Component {
    
    	componentDidMount() {
    
    	}
    
    	render() {
    		return (
    			<div>
    			    <TextBox  selectAllOnFocus placeholder="smart Text Box"></TextBox>
    			</div>
    		);
    	}
    }
    
    ReactDOM.render(<App />, document.querySelector("#root"));
    
    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 TextBox 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 TextBox

  1. Open the "my-project" folder and run:

    npm install smart-webcomponents

  2. Ignored Elements

    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:

    import Vue from 'vue'
    	import App from './App.vue'
    
    	Vue.config.productionTip = false
    	Vue.config.ignoredElements = [
    	  'smart-text-box'
    	]
    
    	new Vue({
    	  render: h => h(App),
    	}).$mount('#app')
  3. Open src/App.vue in your favorite text editor and change its contents to the following:

    App.vue

    <template>  
    	  <smart-text-box id="textbox"></smart-text-box>  
    	 </template>   
    	 <script>  
    	 import "smart-webcomponents/source/styles/smart.default.css";  
    	 import 'smart-webcomponents/source/modules/smart.textbox.js';  
    	 export default {  
    	  name: "app",  
    	  mounted: function() {  
    	   window.Smart(  
    		"#textbox", class {  
    		 get properties() {  
    			return  { placeholder: "Enter First Name"} 
    		 }  
    		}  
    	   );  
    	  }  
    	 };  
    	 </script>  
    	 <style>  
    	  body {  
    	   min-height: 700px;  
    	  }  
    	 </style>  
    	
    We can now use the smart-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-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:
