Ping.js

Ping.js is a small and simple Javascript library to ping response times to servers in pure Javascript! This is useful for when you want to display realtime ping times on a status page which are relative to the user.

JS Fiddle Example: http://jsfiddle.net/alfg/sr0tpn4x/

Example in jQuery: http://jsfiddle.net/alfg/xjqbvt2o/

Usage

var p = new Ping();

p.ping("github.com", function(data) {
  document.getElementById("ping-github").innerHTML = data;
});

API

var p = new Ping();

p.ping(source, callback, timeout)

Creates a ping request to the source.

source IP address or website URL.

callback Callback function which returns the response time in milliseconds.

timeout Optional - Set a timeout in milliseconds.

Notes

Javscript itself doesn't have a native way of sending a "ping", so results may not be completely accurate. Since ajax requests are affected by cross-domain issues (CORS), they are blocked by default. ping.js is using a method of faking an image loading from any host and timing the response time. If there's a better way to do this in Javascript, feel free to create an issue, or pull request so I can review.
