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/
varp=newPing();p.ping("https://github.com",function(data){document.getElementById("ping-github").innerHTML=data;});varp=newPing();Creates a ping request to the source.
source IP address or website URL, including protocol and port (optional). Example: https://example.com:8080
callback Callback function which returns the response time in milliseconds.
timeout Optional - Set a timeout in milliseconds.
Install project:
git clone https://github.com/alfg/ping.js.git
cd ping.js
npm install
npm install -g grunt-cli
Run grunt to build distribution files:
grunt
Open demo/index.html in a browser to test results.
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.
