使用方法

// A simple vanilla JS clock

// Initilize variables for date, hour, minute, second, am or pm, and the final displayed time
var d, h, m, s, ampm, time;

// Your clock!
function displayTime() {
  d = new Date();
  h = d.getHours();
  m = d.getMinutes();
  s = d.getSeconds();
  ampm = h >= 12 ? 'pm' : 'am';
  h = h % 12;

  // Adds zeros to single digit times
  if (h <= 9) { h = '0' + h; } if (m <= 9) { m = '0' + m; } if (s <= 9) { s = '0' + s; } // Assign time format to variable. If you want to change how time is displayed do it here // Example time = h + ":" + m; time = h + ":" + m + ":" + s + " " + ampm; // Print your clock to an element. document.getElementsByClassName("time")[0].innerHTML = time; // Refreshes clock every second. If you're just using minutes change to 60000 setTimeout(displayTime, 1000); } // Run your baller clock! displayTime();
