デジタルらしく”0″ を付けました。
window.onload = function() {
function time() {
var now = new Date();
var nowHours = now.getHours();
var nowMinutes = now.getMinutes();
var nowSeconds = now.getSeconds();
if (nowMinutes < 10) nowMinutes = "0" + now.getMinutes();
if (nowSeconds < 10) nowSeconds = "0" + now.getSeconds();
strTime = nowHours + ':' + nowMinutes + ':' + nowSeconds;
document.getElementById('clock').innerHTML = strTime;
}
setInterval(time, 1000);
}
