How do I listen for triple clicks in JavaScript?

Question

If this is for a double-click:

window.addEventListener(\"dblclick\", function(event) { }, false);

How can I capture a triple-click? This is

Here is the real Triple click event, which triggers only when all of three clicks fired with equal interval.

// Default settings
var minClickInterval = 100,
    maxClickInterval = 500,
    minPercentThird = 85.0,
    maxPercentThird = 130.0;

// Runtime
var hasOne = false,
    hasTwo = false,
    time = [0, 0, 0],
    diff = [0, 0];

$('#btn').on('click', function() {
    var now = Date.now();
    
    // Clear runtime after timeout fot the 2nd click
    if (time[1] && now - time[1] >= maxClickInterval) {
        clearRuntime();
    }
    // Clear runtime after timeout fot the 3rd click
    if (time[0] && time[1] && now - time[0] >= maxClickInterval) {
        clearRuntime();
    }
    
    // Catch the third click
    if (hasTwo) {
        time[2] = Date.now();
        diff[1] = time[2] - time[1];
        
        var deltaPercent = 100.0 * (diff[1] / diff[0]);
        
        if (deltaPercent >= minPercentThird && deltaPercent <= maxPercentThird) {
            alert("Triple Click!");
        }
        clearRuntime();
    }
    
    // Catch the first click
    else if (!hasOne) {
        hasOne = true;
        time[0] = Date.now();
    }
    
    // Catch the second click
    else if (hasOne) {
        time[1] = Date.now();
        diff[0] = time[1] - time[0];
        
        (diff[0] >= minClickInterval && diff[0] <= maxClickInterval) ?
            hasTwo = true : clearRuntime();
    }  
});

var clearRuntime = function() {
    hasOne = false;
    hasTwo = false;
    time[0] = 0;
    time[1] = 0;
    time[2] = 0;
    diff[0] = 0;
    diff[1] = 0;
};

Click button three times with equal interval

Also, I wrote jquery plugin TrplClick, which enables 'trplclick' event
