What is the outcome of XmlHttpRequest.responseText?

I am new to JavaScript and looking to explore the potential of XMLHttpRequest.responseText with a specified URL. Can someone guide me on how to efficiently test this?

let url = "http://m.google.com/"; <br>
let xmlHttp = new XMLHttpRequest(); <br>
xmlHttp.open('GET', url, true); <br>
document.getElementById('main-content').innerHTML = xmlHttp.responseText; <br>

The element with an id of main-content is a <div>. By executing the last line of code, the contents of the <div> will be replaced by the output from xmlHttp.responseText.

If I were to access the source of m.google.com through my regular browser and view its code, which segment would occupy the <div> tag? Also, in what environment should I implement this piece of code for testing purposes?

Just to elaborate, I have an Android application that renders the HTML result within a WebView.

Answer №1

Why not save yourself some headaches and utilize ReactJS? It's widely used in the industry and many employers are looking for candidates with experience in it.

fetch('url.html')
.then(response => response.text())
.then(data => console.log(data));

However, if you're up for a more challenging approach:

let url = "http://m.google.com/"; 
let xhr = new XMLHttpRequest(); 
xhr.open("GET", url, true);

// Set up event listener before sending the request
xhr.onreadystatechange = function() {
  if (xhr.readyState === 4) {
    // Notify user that there's a response available
    alert(xhr.responseText);
    // Check in browser console
    console.log('xhr', xhr);
  }
}
xhr.send(null);

Answer №2

Install Firefox along with Firebug, then explore the XMLHttpRequest object to access the responseText attribute.
