Introduction<\/h2>\n<p><strong>jQuery<\/strong> is nothing but a JavaScript library that comes with the rich functionalities. It&#8217;s small and faster than many JavaScript code written by an average web developer. By using jQuery developers can write less code and do more things, it makes web developer&#8217;s task very easy. In simple word, jQuery is a collection of several useful methods, which can be used to accomplish many common tasks in JavaScript. A couple of lines of jQuery code can do things which need too many JavaScript lines to accomplish. The true power of jQuery comes from its CSS-like selector, which allows it to select any element from DOM and modify, update or manipulate it. Developers can use jQuery to do cool animations like fade in or fade out. They can also change the CSS class of a component dynamically e.g. making a component active or inactive. I have used this technique to implement <em>tabbed UI<\/em> in <code>HTML<\/code>. I can vouch for jQuery that once developers start using it, they will never go back to plain old JavaScript as <em>jQuery<\/em> is <em>clear<\/em>, <em>concise<\/em>, and <em>powerful<\/em>.<\/p>\n<h3><a name=\"whatWeCanHandlejQuery\"><\/a>1.1 What we can handle using jQuery?<\/h3>\n<p><strong>jQuery<\/strong> is very powerful and it provides methods and API to do almost all kinds of thing they can do with the JavaScript. <em>jQuery<\/em> is particularly good in the following areas:<\/p>\n<ul>\n<li><code>HTML<\/code> and DOM manipulation<\/li>\n<li>CSS manipulation<\/li>\n<li>HTML event methods<\/li>\n<li>AJAX<\/li>\n<li>Utilities<\/li>\n<\/ul>\n<p>By using jQuery developers can add a new element into DOM, update existing element from DOM, and can easily remove any element. jQuery\u2019s powerful class and id selector allow developers to select any <code>HTML<\/code> element or group of elements for the selective manipulation. jQuery also allows developers to select and modify the attributes from any <code>HTML<\/code> element in DOM.<\/p>\n<h3><a name=\"howToUsejQuery\"><\/a>1.2 How to use jQuery Library?<\/h3>\n<p><em>jQuery<\/em> is just a small <em>20+ kb<\/em> JavaScript file. If developers want to use jQuery, they just need to download the latest jQuery file from the official <a href=\"https:\/\/jquery.com\/download\/\" target=\"_blank\" rel=\"noopener\">website<\/a> or any of the CDN (i.e. Content Delivery Network) URL which provides the jQuery download capability.<\/p>\n<p>These new APIs make developer&#8217;s life easier, really! But it would be difficult for a beginner to understand this without an example. Therefore, let us create the first &#8220;HelloWorld&#8221; application using the jQuery library.<\/p>\n<h2><a name=\"jQueryExample\"><\/a>2. jQuery Step-by-Step Beginner Example<\/h2>\n<p>Here is a step-by-step guide for implementing the jQuery Library.<\/p>\n<h3><a name=\"toolsUsed\"><\/a>2.1 Tools Used<\/h3>\n<p>We are using Eclipse Kepler SR2, JDK 8 and Maven.
