setTimeout()只执行一次，然后就不跳动了

Question

function countDown($class){    var t = $($class).attr("endTime");    var targetTime = new Date(t);    targetTime = targetTime.getTime();    var nowTime = new Date();    nowTime = nowTime.getTime();    reflash($class,targetTime,nowTime);}function reflash(_class,targetTime,nowTime){    var _second = 1000;    var _minute = _second * 60;    var _hour = _minute * 60;    var _day = _hour * 24;    var difference = targetTime - nowTime;    var days = Math.floor(difference / _day);    var hours = Math.floor((difference % _day) / _hour);    var minutes = Math.floor((difference % _hour) / _minute);    var second = Math.floor((difference % _minute)/_second);    var lastTime = "<i></i>剩余"+days+"天"+nol(hours)+"时"+nol(minutes)+"分"+nol(second)+"秒";    $(_class).html(lastTime);       var t = setTimeout(function(){        reflash(_class,targetTime,nowTime)    },1000);}countDown($(".residual_time"))

Answer 1

把setTimeout换成setInterval试一试
