JQuery实现页面倒计时并刷新

var intDiff = parseInt(600);//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); }else{//当时间耗尽，刷新页面 window.location.reload(); } if (minute <= 9) minute = '0' + minute; if (second <= 9) second = '0' + second; $(".timeShow").html('本页数据还剩下<font>'+minute+'分'+second+'</font>秒刷新,刷新间隔时间: 10 分钟'); intDiff--; }, 1000); } $(function(){ timer(intDiff); }); <span class="timeShow"></span>
