Ajax, the shorter name for Asynchronous JavaScript and XML, is an application combining different programming tools in order to create a web application. Asynchronous JavaScript works by integrating actions completed by a user on a webpage to perform specific requests in the open browser window, instead of the user having to wait for new windows to load and open. This application utilizes different applications in order to complete this action. They include XML, DOM, CSS, DHTML, JavaScript and Microsoft XMLHTTPRequest.
Ajax operates by the use of an engine acting as a middle man between a user’s browser window and the Internet server from which the user is requesting information. Instead of loading a new page or letting a new window open, the Asynchronous JavaScript and XML application initiates its own engine to display the image seen by the user. JavaScript delivers the messages from the user’s interactions with the webpage, to the engine of the application. The Asynchronous JavaScript and XML engine is what makes the application work instantly without the need for new pages or browser windows to load.
There are many different websites that utilize Ajax in order to perform different applications and deliver service requests to website users quickly. One well known website that uses this programming application is Google Maps. The application, as used on Google Maps, allows the user to view their needed information in real time, meaning they will not have to wait on a new browser window to open and load. The earliest forms of XML and Asynchronous JavaScript could only be used with Internet Explorer and could not be used with other web browsers. This is because the application relied on XMLHttpRequest, which only worked with the Windows platform from Microsoft.
At first, Ajax could only be used with Internet Explorer. Now, backend scripting changes have made it possible to use this application with other web browsers and with other operating systems other than Windows. When the application was only usable with Windows and Internet Explorer, a new download had to be activated in order for the application to be used. Now, this is not the case. The application is written into either the HTML or JavaScript code, allowing it to be easily accessed.
