Online Ping Tool With jQuery Ping And Terminal Plugins

A JavaScript solution that makes use of jQuery Terminal.js and Ping.js plugins to create a client-side online ping tool (web app) similar to the Windows ping command.

To ping a website, type "ping" along with the URL or IP address you want to ping, and then hit Enter in the terminal. Hit Control+C to break the ping command. 

The tool pings every second. If the response time is over 1.5 s, the ping times out.

How to use it:

1. Load the necessary jQuery, jQuery Terminal.js, and Ping.js in the document.

<!-- jQuery -->
<script src="/path/to/cdn/jquery.min.js"></script>
<!-- Terminal Plugin -->
<script src="/path/to/cdn/jquery.terminal.min.js"></script>
<link rel="stylesheet" href="/path/to/cdn/jquery.terminal.min.css"/>
<!-- Ping.js Library -->
<script src="/path/to/cdn/ping.js"></script>

2. Create a container to hold the online ping terminal.

<div id="terminal"></div>

3. The main JavaScript (jQueryscript) to activate the online ping tool.

function pinger() {
  var pinging, ad, timer, suc, total, loc, holder;
  var times = [];
  $('#terminal').terminal(function(command, term) {
    var cmd = $.terminal.parse_command(command);
    var address = cmd.args[0];
    
    if (cmd.name == 'ping' && address != undefined) {
      times = [];
      loc = address;
      if(address.substring(0,7) != 'http://' && address.substring(0,8) != 'https://')
      {
        ad = "http://" + address;
      }
      else{
        ad = address;
      }
      term.echo("PINGING " + address);
            var i = 0;
            total = 0;
            suc = 0;
            var output = "";
            var p = new Ping();
            pinging = true;
            
            (function loop() {
                p.ping(ad, function(err, data) {
            // Also display error if err is returned.
            if (err || data >= 1500) {
              output = "Request timeout for ping_seq " + i;
            }
            else{
              holder = data;
              output = "Transmission to " + address + ": ping_seq=" + i + " time=" + data + " ms";
            }
        });
        
        if(output)
        {
          term.echo(output);
          total = i + 1;
          i++;
          if(output.substring(0,1) == 'T')
          {
            suc++;
            times.push(holder);
          }
        }
        
        term.set_prompt("");
        p = new Ping();
        timer = setTimeout(loop, 1000);
            })();
        }
        else if (cmd.name == 'ping' && address == undefined) {
        term.echo("ping: no address to ping");
        }
        else if (cmd.name){
          term.echo(cmd.name + ": command not found");
        }
  },  
  {

            if (e.which == 67 && e.ctrlKey) { // CTRL+c
              term.echo("^C");
              clearTimeout(timer);
              pinging = false;
              
              term.echo("--- " + loc + " ping statistics ---");
              var ploss = (total - suc) * 100.0 / total;
              var round = ploss.toFixed(1);
              term.echo(total + " pings transmitted, " + suc + " successful pings, " + round + "% loss");
              
              var min = Math.min(...times);
              var max = Math.max(...times);
              var avg = (times.reduce((a,b) => a + b, 0) / times.length).toFixed(1);
              var sqrs = times.map(function(value){
            var diff = value - avg;
            var sqr = diff * diff;
            return sqr;
        });
        var sqrAvg = sqrs.reduce((a,b) => a + b, 0) / sqrs.length;
              var std = (Math.sqrt(sqrAvg)).toFixed(1);
              term.echo("Time data: min/max/avg/stddev = " + min + "/" + max + "/" + avg + "/" + std);
              
              term.set_prompt("[[;white;]yourwebsite.com:projects visitor$ ]");
            }
            return false;
        }
      } 
  });
}

4. Run the online ping tool.
