[debug bug] JS: getFullYear is not a function

Report errors ,getFullYear is not a function

Original error code ：

this.formatFun = function(time) {
    
   var year = time.getFullYear();
   var month = time.getMonth()+1;
   var date = time.getDate();
   var hour = time.getHours();
   var minutes = time.getMinutes();
   var seconds = time.getSeconds();
   return year+' year '+month +' month ' + date +' Japan ' + hour +'：' + minutes+'：'+ seconds
  }

reason ：js This sentence is missing from the method called ：

var time = new Date(time);
