本文实例讲述了jquery简单倒计时实现方法。分享给大家供大家参考,具体如下:

var intDiff = parseInt(60); //倒计时总秒数量
function timer(intDiff) {
  window.setInterval(function () {
    var day = 0,
      hour = 0,
      minute = 0,
      second = 0; //时间默认值
    if (intDiff > 0) {
      day = Math.floor(intDiff / (60 * 60 * 24));
      hour = Math.floor(intDiff / (60 * 60)) - (day * 24);
      minute = Math.floor(intDiff / 60) - (day * 24 * 60) - (hour * 60);
      second = Math.floor(intDiff) - (day * 24 * 60 * 60) - (hour * 60 * 60) - (minute * 60);
    }
    if (minute <= 9) minute = '0' + minute;
    if (second <= 9) second = '0' + second;
    $('#day_show').html(day + "天");
    $('#hour_show').html('<s id="h"></s>' + hour + '时');
    $('#minute_show').html('<s></s>' + minute + '分');
    $('#second_show').html('<s></s>' + second + '秒');
    intDiff--;
  }, 1000);
}
$(function () {
  timer(intDiff);
});

希望本文所述对大家jQuery程序设计有所帮助。
