Web Front-endJS TutorialSimple way to handle radio buttons and checkboxes using AngularJS_AngularJSSimple way to handle radio buttons and checkboxes using AngularJS_AngularJS
AngularJS’s form processing is quite simple. When AngularJS uses two-way data binding for form validation, it is essentially helping us with form processing.
There are many examples of using checkboxes, and there are many ways we can deal with them. In this article we will take a look at binding checkboxes and radio buttons to data variables and what we can do with it.
Create Angular form
In this article, we need two files: index.html and app.js. app.js is where all the Angular code is held (it's not big), and index.html is where the actions run. First we create the AngularJS file.
// app.js
var formApp = angular.module('formApp', [])
.controller('formController', function($scope) {
// we will store our form data in this object
$scope.formData = {};
});
In this file, all we do is create the Angular application. We also created a controller and an object to hold all the form data.
Let’s take a look at the index.html file. In this file, we create the form and then perform data binding. We used Bootstrap to quickly layout the page.
<-- index.html -->
<!DOCTYPE html>
<html>
<head>
<!-- CSS -->
<!-- load up bootstrap and add some spacing -->
<link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css">
<style>
body { padding-top:50px; }
form { margin-bottom:50px; }
</style>
<!-- JS -->
<!-- load up angular and our custom script -->
<script src="http://code.angularjs.org/1.2.13/angular.js"></script>
<script src="app.js"></script>
</head>
<!-- apply our angular app and controller -->
<body ng-app="formApp" ng-controller="formController">
<div class="col-xs-12 col-sm-10 col-sm-offset-1">
<h2 id="Angular-Checkboxes-and-Radio-Buttons">Angular Checkboxes and Radio Buttons</h2>
<form>
<!-- NAME INPUT -->
<div class="form-group">
<label>Name</label>
<input type="text" class="form-control" name="name" ng-model="formData.name">
</div>
<!-- =============================================== -->
<!-- ALL OUR CHECKBOXES AND RADIO BOXES WILL GO HERE -->
<!-- =============================================== -->
<!-- SUBMIT BUTTON (DOESNT DO ANYTHING) -->
<button type="submit" class="btn btn-danger btn-lg">Send Away!</button>
</form>
<!-- SHOW OFF OUR FORMDATA OBJECT -->
<h2 id="Sample-Form-Object">Sample Form Object</h2>
<pre class="brush:php;toolbar:false">
{{ formData }}
From Websites to Apps: The Diverse Applications of JavaScriptApr 22, 2025 am 12:02 AMJavaScript is widely used in websites, mobile applications, desktop applications and server-side programming. 1) In website development, JavaScript operates DOM together with HTML and CSS to achieve dynamic effects and supports frameworks such as jQuery and React. 2) Through ReactNative and Ionic, JavaScript is used to develop cross-platform mobile applications. 3) The Electron framework enables JavaScript to build desktop applications. 4) Node.js allows JavaScript to run on the server side and supports high concurrent requests.
Python vs. JavaScript: Use Cases and Applications ComparedApr 21, 2025 am 12:01 AMPython is more suitable for data science and automation, while JavaScript is more suitable for front-end and full-stack development. 1. Python performs well in data science and machine learning, using libraries such as NumPy and Pandas for data processing and modeling. 2. Python is concise and efficient in automation and scripting. 3. JavaScript is indispensable in front-end development and is used to build dynamic web pages and single-page applications. 4. JavaScript plays a role in back-end development through Node.js and supports full-stack development.
The Role of C/C in JavaScript Interpreters and CompilersApr 20, 2025 am 12:01 AMC and C play a vital role in the JavaScript engine, mainly used to implement interpreters and JIT compilers. 1) C is used to parse JavaScript source code and generate an abstract syntax tree. 2) C is responsible for generating and executing bytecode. 3) C implements the JIT compiler, optimizes and compiles hot-spot code at runtime, and significantly improves the execution efficiency of JavaScript.
JavaScript in Action: Real-World Examples and ProjectsApr 19, 2025 am 12:13 AMJavaScript's application in the real world includes front-end and back-end development. 1) Display front-end applications by building a TODO list application, involving DOM operations and event processing. 2) Build RESTfulAPI through Node.js and Express to demonstrate back-end applications.
JavaScript and the Web: Core Functionality and Use CasesApr 18, 2025 am 12:19 AMThe main uses of JavaScript in web development include client interaction, form verification and asynchronous communication. 1) Dynamic content update and user interaction through DOM operations; 2) Client verification is carried out before the user submits data to improve the user experience; 3) Refreshless communication with the server is achieved through AJAX technology.
Understanding the JavaScript Engine: Implementation DetailsApr 17, 2025 am 12:05 AMUnderstanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.
Python vs. JavaScript: The Learning Curve and Ease of UseApr 16, 2025 am 12:12 AMPython is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.
Python vs. JavaScript: Community, Libraries, and ResourcesApr 15, 2025 am 12:16 AMPython and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
