A countdown
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>文档标题</title> </head> <body> <p id="demo"></p> <script> // Set the date we're counting down to var countDownDate = new Date("Feb 1 2100 21:23").getTime(); // Update the count down every 1 second var x = setInterval(function() { // Get todays date and time var now = new Date().getTime(); // Find the distance between now an the count down date var distance = countDownDate - now; // Time calculations for days, hours, minutes and seconds var days = Math.floor(distance / (1000 * 60 * 60 * 24)); var hours = Math.floor((distance % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60)); var minutes = Math.floor((distance % (1000 * 60 * 60)) / (1000 * 60)); var seconds = Math.floor((distance % (1000 * 60)) / 1000); // Output the result in an element with id="demo" document.getElementById("demo").innerHTML = days + " 天 " + hours + " 小时 " + minutes + " 分钟 " + seconds + " 秒"; // If the count down is over, write some text if (distance < 0) { clearInterval(x); document.getElementById("demo").innerHTML = "EXPIRED"; } }, 1000); </script> </body> </html>
