php+js实现倒计时功能
js部分
setInterval("time_controller()",1000); functiontime_controller(){ $(".time_val").each(function(){ vartime_id="time_show_"+$(this).attr('for'); vartime_val=$(this).attr('value'); $(this).attr('value',time_val-1); show_time(time_id,time_val*1000); }); } functionshow_time(id,timestamp) { vartimer=document.getElementById(id); varstr_time,int_day,int_hour,int_minute,int_second; vartime_distance=timestamp; if(time_distance>0) { int_day=Math.floor(time_distance/86400000) time_distance-=int_day*86400000; int_hour=Math.floor(time_distance/3600000) time_distance-=int_hour*3600000; int_minute=Math.floor(time_distance/60000) time_distance-=int_minute*60000; int_second=Math.floor(time_distance/1000) if(int_hour<10) int_hour="0"+int_hour; if(int_minute<10) int_minute="0"+int_minute; if(int_second<10) int_second="0"+int_second; str_time="<b>剩余时间:"+int_day+"天"+int_hour+"小时"+int_minute+"分钟"+int_second+"秒</b>"; timer.innerHTML=str_time; }else{ timer.innerHTML="<b>剩余时间:0天0小时0分钟0秒</b>"; } }
html部分,php和js的时间倒计时
<divid="time_show_{$list.cmd_id}"></div> <inputtype="hidden" for="{$list.cmd_id}"value="{$list.time_val}"/>
