CLIENT SIDE SCRIPTING
CLIENT SIDE PROGRAMMING:
Client-side programming refers to the development of scripts that run directly in the user’s web browser rather than on the web server. It is mainly used to create interactive and dynamic web pages, improve user experience, and reduce server load. Since the code executes on the client’s machine, it enables faster responses to user actions such as button clicks, form submissions, mouse movements, and page navigation. Client-side programming works closely with HTML and CSS to control the structure, style, and behavior of web pages.
JAVA SCRIPT:
JavaScript is a high-level, interpreted programming language used to make web pages interactive and dynamic. It runs directly in the web browser and allows developers to add functionality such as form validation, pop-up messages, image sliders, and dynamic content updates. While HTML is used to structure a webpage and CSS is used to style it, JavaScript controls the behavior of the webpage.
JavaScript works by interacting with the Document Object Model (DOM), which represents the structure of a webpage. It can respond to user actions like clicks, typing, and mouse movements through events. JavaScript supports basic programming concepts such as variables, functions, loops, and conditional statements. Because of its flexibility and wide browser support, JavaScript is an essential technology in modern web development.
Java script code are added using script tag<script>
Eg:
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<h1> JavaScript Tutorials</h1>
<script>
//write JavaScript code here..
alert('Hello, how are you?')
</script>
</body>
</html>
JQUERY:
jQuery is a fast and lightweight JavaScript library designed to simplify client-side scripting in web development. It helps developers write less code while performing common tasks such as selecting HTML elements, handling events, creating animations, and making AJAX requests. Instead of writing complex JavaScript code, jQuery provides simple and easy-to-use methods that make development faster and more efficient.
One of the main advantages of jQuery is its ability to manipulate the Document Object Model (DOM) easily. It also ensures better cross-browser compatibility, meaning the code works consistently across different web browsers. With its concise syntax and powerful features, jQuery became widely popular for building interactive and dynamic web pages.
Eg:
<script src="jquery-3.6.3.js"></script>
<script>
$(document).ready(function()
{ $("div").click(function()
{
alert("Hello, world!");});
});
</script>
<div>Click on this to see a dialogue box.</div> To explore more about client side programming like javascript and jquery Click here
