How to Ping Server in JavaScript

For pinging an URL, we will receive a message from the server if that site is valid or active. If the server verdicts that the URL is on air, it will satisfy a conditional statement.

The basic drive includes an ajax code boundary that will define the configuration for the request. Let’s direct examine an example to get a grip on the concept.

Use Ajax to Ping an URL in JavaScript

We will take an input element to enter the user preferred URL, and right after the submit, the onclick attribute will invoke the ping() function. We will set the configuration for URL requests in the JavaScript code lines.

We will not have any external if-else statement to infer the response. Rather we will have multiple statusCode to return statements based on the servers’ responses.

Code Snippet - index.html:

<!DOCTYPE html>
<html lang="en">
    <script src="index.js"></script>
    <script type="text/javascript" src=
    <title>Ping using JavaScript</title>
    <label for="url">
        URL you want to ping:
      <input type="text" id="url"
        name="url" style="margin: 10px;"><br>
        <input type="submit" value="Submit"

Code Snippet - index.js:

function ping() {
  // The custom URL
  var URL = $('#url').val();
  var settings = {
    cache: false,
    dataType: 'jsonp',
    async: true,
    crossDomain: true,
    url: URL,
    method: 'GET',
    // For response
    statusCode: {
      200: function(response) {
        console.log('Status 200: Page is up!');
      400: function(response) {
        console.log('Status 400: Page is down.');
      0: function(response) {
        console.log('Status 0: Page is down.');
  // Sends the request and observes the response
  $.ajax(settings).done(function(response) {


Use Ajax to Ping an URL

The console responds to the statement with the status 200 and says the page is active, and this certain response is titled pong. This is the way you ping a specific URL to check its validity.
