Learning AJAX Online: A Student’s Guide
What is AJAX?
AJAX is a web development technique used for creating interactive web applications. AJAX is the short form for “Asynchronous JavaScript and XML”.
AJAX allows web pages to be updated asynchronously by exchanging small amounts of data with the server behind the scenes. This means that a web page can update without having to reload the entire page.
AJAX is used to create a more responsive and interactive user interface. When a user makes a change on a web page, an AJAX request is made to the server.
The web server processes the request and then sends a response back to the web page. The web page can then update itself without reloading the entire page.
AJAX requests are made using the XMLHttpRequest object. This object is available in all modern browsers. The data that is exchanged between the browser and the web server is usually in the form of XML or JSON.
The XMLHttpRequest object can be used to exchange any type of data, not just XML or JSON. AJAX requests are usually made using the GET or POST methods.
The GET method is used to retrieve data from the server, while the POST method is used to submit data to the server.
The data that is exchanged between the browser and the server can be in any format, including XML, JSON, text, or even binary data.
AJAX requests can be made to any type of server, including web servers, application servers, and database servers.
Why learn AJAX?
The goal of AJAX is to exchange data with a server without reloading the entire page. AJAX is a particular way of using JavaScript, XML, and HTTP requests. AJAX allows you to:
- Make server requests without reloading the page
- Receive and process data from the server without reloading the page
- Update parts of a page without reloading the entire page
AJAX is not a single technology, but rather a group of technologies.
The term AJAX was coined in 2005 by Jesse James Garrett, who explained the benefits of using multiple technologies together to create web applications that are more responsive and interactive.
The key technologies used in AJAX are:
- HTML and CSS for presentation
- JavaScript for interaction with the user
- The XMLHttpRequest object for communication with the server
- The DOM for dynamic display of and interaction with data
When used correctly, AJAX can improve the user experience of your web application. AJAX is a group of technologies, so it can be challenging to learn.
However, once you understand the basics of AJAX, you can start to create web applications that are more dynamic and user-friendly.
Prerequisites
Assuming the reader has a basic understanding of HTML, CSS, and JavaScript, the following are prerequisites to learn AJAX:
- A good understanding of XML and its syntax
- A solid understanding of the DOM (Document Object Model)
- Familiarity with the XMLHttpRequest object and its methods
- A basic understanding of server-side technologies such as PHP, ASP, or JSP With the above concepts mastered, one can start learning AJAX by following any of the numerous tutorials and guides available online.
