Build your digital clock rolling of JS code that some customers need to show time on the site, today cnc foam cutting machine website customers require us to engage in a cool clock effect, where the code is released, for your reference.

JS code:

<script>
'use strict';
var size = 86;
var columns = Array.from(document.getElementsByClassName('column'));
var d = undefined,
    c = undefined;
var classList = ['visible', 'close', 'far', 'far', 'distant', 'distant'];
var use24HourClock = true;

function padClock(p, n) {
    return p + ('0' + n).slice(-2);
}

function getClock() {
    d = new Date();
    return [use24HourClock ? d.getHours() : d.getHours() % 12 || 12, d.getMinutes(), d.getSeconds()].reduce(padClock, '');
}

function getClass(n, i2) {
    return classList.find(function (class_, classIndex) {
        return i2 - classIndex === n || i2 + classIndex === n;
    }) || '';
}

var loop = setInterval(function () {
    c = getClock();

    columns.forEach(function (ele, i) {
        var n = +c[i];
        var offset = -n * size;
        ele.style.transform = 'translateY(calc(50vh + ' + offset + 'px - ' + size / 2 + 'px))';
        Array.from(ele.children).forEach(function (ele2, i2) {
            ele2.className = 'num ' + getClass(n, i2);
        });
    });
}, 200 + Math.E * 10);
</script>
