What is Ajax? Understand with PHP 7.2
The Ajax will help you to insert dynamic content in the webpage.
Where do you use Ajax? You can use ajax language in any program if you need to call the server side language in your client Browser. Using this method you can transfer the data from the client to the server you can also access the server side values to the client browser. So it will help you to communicate client and server at the same time.
Ajax utilizes the following technologies.
- Server-side programming languages
- The extensible markup language (XML)
- HTML and CSS
- Document object model (DOM)
Let’s take each of them.
Server-side programming languages
Using server-side languages you can manipulate data or retrieve data from the database. Everything that you can do with the server side languages you can do this with the ajax by just calling the server side language dynamically.
The extensible markup language (XML)
The extensible markup language used to safely transfer data from the server-side programming language to the client side Browser.
HTML and CSS
To place dynamic content on the webpage you can use HTML. To style your document we use cascading style sheet. the same way used in ajax technology also. Replace the dynamic content we use HTML tag and CSS for styling to that content.
Document object model (DOM)
You can also use document object model to place dynamic content in the webpage. In the previous topic we see you can use HTML to place the dynamic content there is one more way using document object model. Referencing to the node will insert the dynamic content in the document or you can create the node also.
