AngularJS 支付倒计时功能实现思路

new Date($scope.order.createtime.replace(/\-/g, "/")) 

<div ng-class="{true: 'payCountDown', false: ''}[payClass]" ng-bind="payCountDown"> 
</div> 

$scope.order = Storage.get("order");//order为后台传来的订单信息，里面包含订单创建时间 
  var createTime;//订单创建时间 
  var curTime;//当前时间 
  var totalSecond;//设置计时总时间（分钟） 
  if($scope.order.createtime !=null){ 
    //为了支持safari浏览器 
    createTime=new Date($scope.order.createtime.replace(/\-/g, "/")).getTime(); 
    curTime=new Date().getTime(); 
    totalSecond=Math.round((createTime+15*60*1000-curTime)/1000); 
  }else{ 
    totalSecond = 15 * 60;  
  } 
   
  /** 
   * 支付倒计时 
   */ 
  timePromise = $interval(function(){  
    if (totalSecond >= 0) { 
      var t1 = Math.floor(totalSecond / 60); 
      var m = t1 < 10 ? "0" + t1 : t1; 
      var t2 = totalSecond - t1 * 60; 
      var s = t2 < 10 ? "0" + t2 : t2; 
      totalSecond = totalSecond - 1; 
      $scope.payClass=true;//添加class 
      $scope.payCountDown="支付剩余时间："+m+"分钟"+s+"秒" 
    } else { 
      $scope.confirmPay=true; 
      $scope.payClass=true;//添加class 
      $scope.payCountDown= "支付超时，请重新下单！"; 
      $interval.cancel(timePromise);//终止倒计时 
    } 
  },1000) 

.payCountDown{ 
  color:#FFFFFF; 
  background-color:red; 
  text-align:center; 
  padding:14px 0; 
  opacity:0.8 
}

begin 
 sys.dbms_job.submit(job => :job, 
           what => 'UpdateOrderStatues;', 
           next_date => to_date('05-06-2017 10:05:50', 'dd-mm-yyyy hh24:mi:ss'), 
           interval => 'sysdate +1/1440'); 
 commit; 
end;
