jquery实现一个全局计时器(商城可用)

var arrList =$(".stime");
setInterval(function(){
 //遍历数组
 for(var i = 0,l = arrList.length; i<l ;i++ ){
  var elem = arrList[i];
  //格式化时间插入HTML文档
  $(elem).html(DateDiff( new Date(), new Date($(elem).attr("time") ), elem ));
 }
},1000);

/DateDiff 处理/
function DateDiff(t1, t2, elem){
 //GTM CST 时间相差14小时 
 var diff = t1.setHours(t1.getHours()+14) - Date.parse(t2);
 //超过一天显示warning色
 if(diff>(1000606024)){
  $(elem).css({color:"rgb(247, 186, 42)"});
 }
 return ShowTime(diff);
}

/fuc 计时显示处理/
function ShowTime(ms){
 var obj = {
  "天" : 1000606024,
  "时" : 10006060,
  "分" : 100060
  /
  "秒" : 1000
  /
 };
 var tmp = ms;
 var str = "";
 for( var i in obj ){
  //向下取整 1.5天 => 1天
  s = Math.floor( tmp / obj[i] );
  tmp = tmp % obj[i];
  str += s+i;
 }
 return str;
}
