Ajax as one of the popular modern technologies

Ajax

Ajax is one of the popular modern technologies that allows you to access the server without reloading the page. It is actively used for dynamic loading of page content. For the first time this technology was learned in February 2005, this term was designated by Jesse James Garrett. Google Maps and the Gmail email client were the first applications to incorporate this technology.

It stands for Asynchronous Javascript and XML. That is, it is based on Javascript and XML, which developers have been using for more than one year. With the help of this technology, you can significantly improve the usability of the resource, its functionality and the appearance of pages.

AJAX examples:

• Voting system. Have you ever evaluated a product that you purchased online? This is exactly what AJAX uses. After clicking on the button, the calculation will be updated, and the page will remain unchanged.
• Chats. On many resources, you can see online chats that allow you to contact a manager or a regular technical support employee for help. Thanks to AJAX, the page will not constantly refresh when sending and receiving messages.
• Twitter notification. Twitter developers have recently decided to implement AJAX technology on the social network. When new tweets appear, the Internet resource will automatically update new numbers. This will not affect the main object - the page.

As you can see, AJAX makes multitasking easy.

The page does not change, and this helps to keep the filled data unchanged, the ability to correct errors;
• The minus of the impossibility of indexing by search engines can be turned into a plus, if you need to hide the actions, leave them unnoticed, hide them. For example, links to other sites will be visible to users, but not to search engines;
