Question

what ajax query?

Answer 1

I understand your interest in AJAX technology. An AJAX query typically refers to the process of sending an asynchronous HTTP request from a web page to a server. This allows the page to update dynamically without needing to refresh the entire page.

Here's a brief example of an AJAX query using vanilla JavaScript:

var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
  if (this.readyState == 4 && this.status == 200) {
    // Handling the response from the server
    console.log(this.responseText);
  }
};
xhttp.open("GET", "url-to-server-endpoint", true);
xhttp.send();

In this example, when the `xhttp.send()` method is called, it initiates the asynchronous request to the server. Upon receiving a response, the provided callback function processes the data.

Real-world uses of AJAX queries include fetching data from a server, submitting form data without refreshing the page, and updating parts of a webpage dynamically.
