event.target和时间计算实例详解

Vue.filter("time", function(value) {
 var time;
 var minutes = timeErrand(value);
 if(minutes){
 time = minutes+"分钟";
 }else {
 var s = new Date(value);

 hour= now.getHours(),
 minute = now.getMinutes();
 return year + '.' + month + '.' + date; 
}

function timeErrand(value){
 var date1 = value; //开始时间
 var date2 = new Date(); //结束时间
