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

Answer 1

I am working on a javascript code editor and I had to listen for triple click and here is the solution that will work for most browsers:

// Function to get mouse position
var getMousePosition = function (mouseEvent) {
    var currentObject = container;
    var currentLeft = 0;
    var currentTop = 0;
    do {
        currentLeft += currentObject.offsetLeft;
        currentTop += currentObject.offsetTop;
        currentObject = currentObject.offsetParent;
    } while (currentObject != document.body);
    return {
        x: mouseEvent.pageX - currentLeft,
        y: mouseEvent.pageY - currentTop
    }
}

// We will need a counter, the old position and a timer
var clickCounter = 0;
var clickPosition = {
    x: null,
    y: null
};
var clickTimer;

// The listener (container may be any HTML element)
container.addEventListener('click', function (event) {

    // Get the current mouse position
    var mousePosition = getMousePosition(event);

    // Function to reset the data
    var resetClick = function () {
        clickCounter = 0;
        var clickPosition = {
            x: null,
            y: null
        };
    }

    // Function to wait for the next click
    var conserveClick = function () {
        clickPosition = mousePosition;
        clearTimeout(clickTimer);
        clickTimer = setTimeout(resetClick, 250);
    }

    // If position has not changed
    if (clickCounter && clickPosition.x == mousePosition.x && clickPosition.y == mousePosition.y) {
        clickCounter++;
        if (clickCounter == 2) {
            // Do something on double click
        } else {
            // Do something on triple click
            resetClick();
        }
        conserveClick();
    } else {
        // Do something on single click
        conserveClick();
    }
});

This approach checks if the user has not changed cursor's position, you still can do something when you have single click or double click. Hope this solution will help everybody who will need to implement a triple click event listener :)
