js提交时间字段时时区不对后缀带Z的解决方法

var date = new Date(你的日期字段)
newtime= date.getFullYear() + '-' + this.checkTime(date.getMonth() + 1) + '-' + this.checkTime(date.getDate()) + ' ' +this.checkTime(date.getHours()) +':'+this.checkTime(date.getMinutes())+":"+this.checkTime(date.getSeconds())
checkTime(i) {
  if (i < 10) {
   i = '0' + i
   }
   return i
},
