In this article, we will see the different scenarios where jQuery can be effectively implemented. Here, we are using the JavaScript file for jQuery to create the jQuery example related to whether it is effective or not. You can use the absolute URL of the jQuery file or download it from jquery.com.

jQuery is an open-source JavaScript library that simplifies the interactions between an HTML/CSS document, or more precisely the Document Object Model (DOM), and JavaScript. With a simple-to-use API that is compatible with a wide range of browsers, it makes tasks like HTML document navigation and modification, animation, event handling, and AJAX quite straightforward. The major goal of jQuery is to make it simple for you to utilize JavaScript on your website to enhance its interactivity. It is also known as “write less, do more” because it links several routine operations that often require many lines of JavaScript code to complete into methods that can be performed whenever necessary. AJAX requests and DOM manipulation are only a couple of the difficult JavaScript features that may be greatly simplified. Below are a few examples of the different scenarios where jQuery may be used successfully and are discussed in more detail:

  • Support for AJAX and animations: There are several built-in animation effects included with jQuery. Additionally, employing AJAX technology greatly aids in the development of a responsive and feature-rich website. Therefore, most web developers prefer to utilize to create websites more engaging, interactive, tidy, and user-friendly.
  • Search-engine-friendly: Even though all of jQuery’s content is shown as text, several of its effects are almost perfect copies of those in Flash. As a result, jQuery is less resource-intensive than Flash and all search engine bots can access the content.
  • Plugins: It is a piece of code written in a typical JavaScript file. These files offer practical jQuery functions that may be used in conjunction with jQuery library functions.
  • Support across browsers: jQuery is the most popular JavaScript library that works with all current browsers. Further support is provided for CSS3 selectors as well as basic X Path syntax.
  • Writing Less, Doing More: jQuery transforms several routine operations that involve writing a lot of JavaScript code into methods that can be called with only one line of code. As a result, 25 lines of traditional JavaScript code are comparable to five lines of jQuery. Smaller files and quicker website loading are the results of this.
  • Manipulation of DOM: Using the cross-browser open-source Sizzle selection engine, jQuery makes it simple to choose DOM components, negotiate with them, and alter them.
  • Learning simplicity: Due to its simpler code than JavaScript, JQuery is relatively easy to learn and doesn’t require any special prerequisites. The time needed to design and launch a website may be greatly decreased by using simple coding standards and grammar. Additionally, using jQuery comes with a robust collection of built-in plugins, so developers don’t need to have any design skills or know how to create websites.
  • jQuery creates animated apps that resemble flash: Flash takes time to learn & requires years of experience to create the animation with the help of Flash. Although, you can create animations using simple HTML and JavaScript when using jQuery. There is a tonne of plugins available as well, which further simplify this procedure. 
  • Simple connection with the IDE for Visual Studio: Extensions for Visual Studio are available to assist in integrating jQuery libraries into.Net framework applications. The 2010 edition of Visual Studio is compatible with this integration of JQuery libraries into the Net framework. This connection is made possible via Visual Studio’s NuGet package extension. The IntelliSense functionality of Visual Studio is activated with the aid of this integration. With this feature, all jQuery methods are automatically filled up, and errors are shown when the syntax is incorrect.
  • A jQuery element has continued to appear even with JavaScript deactivated: For some browsers to effectively render all the material, installing Adobe Flash was a must. With jQuery, this is not the case. Today, creating and altering online pages mostly involves manipulating the HTML DOM. Therefore, the material will still be displayed even if JavaScript is deactivated in the browser.

Example: This example describes the basic implementation of jQuery.

Javascript




<!DOCTYPE html>
<html>
 
<head>
    <title>
        effective jQuery Example
    </title>
    <script type="text/javascript" src=
    </script>
    <script type="text/javascript" language="javascript">
        $(document).ready(function () {
            $("h1").css("color", "green");
            $("p").css("background-color", "pink");
            $("#txt").css("font-family", "sans-serif");
        }); 
    </script>
</head>
 
<body>
    <h1>GeeksforGeeks</h1>
    <div>
        <p>
