Ajax Course For Free

Ajax stands for Asynchronous JavaScript and XML. It is not a programming language. It is a web development technique that uses different web technologies on the client-side to create asynchronous web applications. Web applications can send and retrieve information from the server asynchronously in the background with Ajax. It does not interfere with the display and behavior of the pre-existing page. Ajax allows web pages by decoupling the data interchange layer from the presentation layer, extension, web applications, to make changes in the content dynamically without the necessity to reload the entire page. Currently, day-to-day implementations use JSON instead of XML in practice. 

Ajax is more a programming concept rather than a technology. In addition, styling and markup of information are achieved through HTML and CSS. Webpages are modified by Javascript to display dynamically. It makes way for the users to interact with the recent data. The built-in XMLHttpRequest object helps execute Ajax on the web pages. This way, it will enable the websites to load content to the screen without the need to refresh the page. Ajax is neither a new technology nor a new language. It is an existing technology that is used according to changing requirements in the technology. 

Ajax represents a broad group that implements a web application to communicate with the server in the background. It does not interfere with the current state of the page. The incorporated technologies in Ajax are:

• HTML or XHTML and CSS to display web pages

• The document object model to display and interact with the data

• JSON and XML to interchange the data. XSLT to manipulate XML data 

• The XMLHttpRequest object to communicate asynchronously

• JavaScript brings all these technologies together 

There have been developments in the technologies used in Ajax applications ever since. That includes the definition of team Ajax itself. XML is not needed to interchange data since newer technologies like Ajax have taken over, hence removing the need for XSLT to manipulate the data. JavaScript Object Notation (JSON) is generally used as an alternative format to interchange data. There are other formats such as HTML or plain text that can also be used. JQuery and a variety of other popular JavaScript libraries include abstractions in executing Ajax requests. 

Ajax comprises a set of web development techniques that are used to create web applications. The free Ajax certificate course offered by Great Learning will take you through the definition, working, compatibilities, and technologies incorporated with Ajax. This course is designed carefully to help individuals understand the concepts thoroughly. You can also learn JavaScript and XML to understand Ajax better. You will gain a certificate for Ajax after successful completion of the course. Happy Learning!
