vue 用当前对象获取坐标距离

selectMeeting(day, jsEvent) {
//jsEvent 这个传进来就是$event
this.selectDay = day;
this.showMore=false;
this.meetingShowMore = true;
this.morePos = this.computePos(jsEvent.target);
//byludan 如果窗口到最右边往左移动
let totalMub=this.$refs.dates.getBoundingClientRect().width
let totalLeft=this.morePos.left
let totalWidth=226
if(totalLeft+totalWidth>totalMub){
this.morePos.left -= 189;
// console.log(‘morePos====’,totalMub-(totalLeft+totalWidth))
// console.log(‘ludanaaa11====’,jsEvent.target.getBoundingClientRect())
// console.log(‘ludanaaa====22’, this.$refs.dates.getBoundingClientRect())
// this.$emit(“meetingclick”, day.date, events, jsEvent);
}

  // this.morePos.left -= 80;
  // console.log('这里是当天的数据day===',day)
  // console.log('这里是当天的数据jsEvent===',jsEvent)
  let events = day.events.filter(item => {
    return item.eventType == 'meeting';
  });



}, //byludan end
//下面这个函数就是重点可以获取的左右坐标
computePos(target) { 
  let eventRect = target.getBoundingClientRect();
  let pageRect = this.$refs.dates.getBoundingClientRect();
  console.log()
  return {
    left: eventRect.left - pageRect.left,
    top: eventRect.top + eventRect.height - pageRect.top
  };
},
