What is Ajax programming?

Ajax( Asynchronous JavaScript And XML) is a set of web development techniques that use masny web technologies on the client-side to create asynchronous web applications.

With Ajax, web applications can asynchronously send and retrieve data from a server without interfering with the existing page’s display and behavior.

Ajax is not a programming language, and it requires a built-in browser with the XMLHttpRequest object that requests data from the server. It also uses JavaScript and HTML DOM to display the data.

Ajax programming

Ajax is widely used in client-side programming (e.g., JavaScript) to allow for data to be sent and received to and from a database/server. The data in the background can be easily exchanged without compromising the user experience.

A user may require a script to load from another .js file. This is fairly simple as all you need to do is use the async attribute of your script tag. For example, given that you want want to load a script from file.js, the command looks like this:

<script src="example.js" async></script> 

A user can also make use of Ajax jquery cdnjs in the following way:

Ajax functions

Then there are Ajax functions. There are many functions in Ajax that follow the same convention and have the following two components:

$.ajax(url [, settings])

Here, the url refers to a string that contains the URL to which the request was sent. For settings, it is a type object that contains a set of key/value pairs that configure the Ajax request. Check out the full list of available functions here.

$.ajax('test.html', {
    success: function(result) {
        $('#test1').html(result);
    }
});

The code above is a simple demonstration of an Ajax program code using Ajax with jQuery. The URL used is test.html, which means we are requesting that URL. Then, the result is taken and stored in the element with id test1, given that the status of the function is a success.
