Describe Ajax With its Implementation Process ? Give an example?

Hello,
Here’s a general overview of the implementation process of Ajax:

Set up the HTML page. Then, ưrite JavaScript code. In the JavaScript section of your HTML page or in an external JavaScript file, you’ll write the code to handle the Ajax functionality. Next, attach event handlers to trigger Ajax requests. After that, create an XMLHttpRequest object. Inside the event handlers, create an XMLHttpRequest object, which allows you to make HTTP requests to the server. Alternatively, you can use the newer Fetch API or other libraries like Axios or jQuery.ajax for simplified Ajax requests.Next, set up the request parameters, such as the HTTP method (GET, POST, etc.), URL, headers, and data payload (if applicable). Then, send the request. Call the appropriate method on the XMLHttpRequest object (e.g., open() and send()) to send the request to the server. The request is typically asynchronous, allowing the page to continue functioning while waiting for a response from the server. Finally, define a callback function that will handle the server’s response when it is received. slope game

Here’s a simple example to demonstrate the implementation of Ajax using plain JavaScript:

html
<!DOCTYPE html>
<html>
<head>
 <script>
    function loadContent() {
      var xhttp = new XMLHttpRequest();
      xhttp.onreadystatechange = function() {
 if (this.readyState === 4 && this.status === 200) {
          document.getElementById("content").innerHTML = this.responseText;
 }
 };
      xhttp.open("GET", "data.txt", true);
      xhttp.send();
 }
 </script>
</head>
<body>
 <button onclick="loadContent()">Load Content</button>
 <div id="content"></div>
</body>
</html>

In this example, clicking the “Load Content” button triggers the loadContent() function. It creates an XMLHttpRequest object, sets up an event handler to handle the response, and sends a GET request to the server to fetch the content from the “data.txt” file. The received content is then inserted into the

element with the id “content” using document.getElementById(“content”).innerHTML.
