jQuery helps AJAX

The last several years have seen an increase in more JavaScript libraries and frameworks. JavaScript is the de facto language for client-side scripting in any web application because its engine is an integrated component in any major browser. Developers have invented several different frameworks, but any client-side scripts you write for web development will use JavaScript. The evolution has started in 2004 within several Google products such as Gmail, Google Maps and Youtube in addition to Facebook tabs. At that time, AJAX has been introduced. AJAX is about loading data in the background and display it on the webpage, without reloading the whole page. jQuery provides several methods for AJAX functionality.

AJAX Programming

Google made AJAX popular in 2004 when it introduced a text box that would "guess" the phrase or keyword you were typing in the search engine. The predictive search text box would display the next letter or word that it thought you meant as you typed. This technique was done using AJAX. With each keystroke, Google did a search in its database for the best suggestion. It helped users find popular sites and eliminated many of the common spelling mistakes made by search users.

Now, AJAX is used for so much more, but its main use is querying database tables or submitting data to a server asynchronously. Asynchronous submissions mean that when the code is sent to the web server, processing happens in the background without requiring the user to wait for the page to refresh. Web developers can retrieve data while other parts of the site display, or they can submit data without making the current page reload. This type of programming improves site speed and user engagement.

JQuery Programming

JQuery is a JavaScript framework, but it's mainly used to manipulate HTML elements in the DOM. The document object model (DOM) represents all of the elements you see on a web page. The DOM organizes the elements so that the developer can reference them easily. If you've ever written JavaScript scripts, it can get tedious to reference the right element. With jQuery, you can use shorthand to reference the right element based on its ID, style sheet class, location or even HTML tag name.

You don't need jQuery to work with client-side scripting, but the library contains so many extras that it makes the entire process much easier. You can more easily change CSS classes dynamically, create popups using div containers, and you can display data based on user input. The advantage is that your code is much faster and efficient. It also takes a load off of the server that must process pages if you use server-side scripting.

With most projects, you will use jQuery with the occasional AJAX call. JQuery reduces the time it takes you to build dynamic sites, and AJAX makes it easier to load content from a database. They have similar syntax, and you can mix AJAX, jQuery and vanilla JavaScript together in your code.

If you decide to get into any type of website programming, you'll need to learn AJAX and jQuery. With the jQuery AJAX methods, you can request text, HTML, XML, or JSON from a remote server using both HTTP Get and HTTP Post - And you can load the external data directly into the selected HTML elements of your web page!. It's especially useful with front-end design. The first step is to learn JavaScript. Once you have the syntax mastered, you can quickly understand these two frameworks.
