Working With XMLHttpRequest

The XMLHttpRequest is a Javascript object that is used to interact with web servers.

The XMLHttpRequest() is a Javascript function that makes it possible for developers to fetch XML data from the database without reloading the entire page.

Now, XMLHttpRequest is not just limited to XML alone. It can be used to retrieve any type of data, especially from an API.

Let us see an example of how it works.

let xhr = new XMLHttpRequest(); //Invoke an instance
xhr.onload = success; //call success function
xhr.onerror = error; //call error function
xhr.open('GET',' fetch('https://api.github.com/repos/javascript-tutorial/en.javascript.info/commits'); //initiate a request
xhr.send(); //send the request

//Handle success
function success(){
let data = JSON.parse(this.responseText);
console.log(data);
}

//Handle error
function error(err){
console.log(`Request failed: ${err}`);
}

Result:
