拖拽（一个图片怎么重复拖动到多个位置，初始位置的图片一直都在）

 <div id="1" class="content1">
                          <img v-if="shangf" id="geshang" style="position:absolute;cursor: move;z-index:1200;" @mousedown="down" @mousemove="move" @mouseup="up" src="../../../assets/images/C.png" class="img1" />
                          <img  @click="regeshang"  style="position: relative;"  src="../../../assets/images/geshang.png" class="img1" />
                          <div style="margin-top:6px">割伤</div>
                          <div >（CUT）</div>
                        </div>

 dragging:false,
    boxX:'',
    boxY:'',
    mouseX:'',

    shangf:false,


 regeshang(){
      console.log('测试时间是否只执行一次')
      if(this.tuodongshow==true){ 
        this.$Message.error('请选择您要执行的操作')
      }else{
        this.shangf=true
      }
    },
  //  拖动
    // 鼠标按下
    down(e){
      
       var box= document.getElementById('geshang')
       this.dragging = true
         console.log(box.offsetLeft,box.offsetLeft,'获取元素所在的坐标')
        // 获取元素所在的坐标
        this.boxX = box.offsetLeft
        this.boxY =box.offsetTop
        // 获取鼠标所在的坐标
        this.mouseX = parseInt(this.getMouseXY(e).x)
        this.mouseY = parseInt(this.getMouseXY(e).y)

        // 鼠标相对元素左和上边缘的坐标
        this.offsetX = this.mouseX - this.boxX
        this.offsetY = this.mouseY - this.boxY

     getMouseXY(e){
        var x = 0, y = 0
        e = e || window.event

        if (e.pageX) {
            x = e.pageX
            y = e.pageY
        } else {
            x = e.clientX + document.body.scrollLeft - document.body.clientLeft
            y = e.clientY + document.body.scrollTop - document.body.clientTop
        }

        return {

    },
    // 鼠标移动调用的函数
    move(e){
      var box= document.getElementById('geshang')
       if (this.dragging) {
         console.log('移动中')
            // 获取移动后的元素的坐标
            var x = this.getMouseXY(e).x - this.offsetX

            var width = document.documentElement.clientWidth - box.offsetWidth
            var height = document.documentElement.clientHeight - box.offsetHeight
            console.log(document.documentElement.clientWidth,box.offsetWidth,'可移动范围')

            // 给元素及时定位
            box.style.left = x + 'px'
            box.style.top = y + 'px'
            console.log(box.style.left,box.style.top)
        }

    },
    up(){
      this.dragging=false
    },
   

克隆一个img对象，拖动这个img，而不是原来的img，改下down和move事件

            down(e) {
                var box = document.getElementById('geshang')
                this.dragging = true
                console.log(box.offsetLeft, box.offsetLeft, '获取元素所在的坐标')
                // 获取元素所在的坐标
                this.boxX = box.offsetLeft
                this.boxY = box.offsetTop
                // 获取鼠标所在的坐标
                this.mouseX = parseInt(this.getMouseXY(e).x)
                this.mouseY = parseInt(this.getMouseXY(e).y)
                // 鼠标相对元素左和上边缘的坐标
                this.offsetX = this.mouseX - this.boxX
                this.offsetY = this.mouseY - this.boxY

                ///////////////////////////
                this.dragImg = box.cloneNode(true);//
                this.dragImg.id = '';
                this.dragImg.style.left = box.offsetLeft + 'px'
                this.dragImg.style.top = box.offsetTop + 'px'
                //注册克隆图片的事件@mousedown="down" @mousemove="move" @mouseup="up"
                this.dragImg.addEventListener('mousemove', (e) => { this.move(e) })
                this.dragImg.addEventListener('mouseup', (e) => { this.up(e) })
                document.body.appendChild(this.dragImg);//
                ///////////////////////////
       },

            
move(e) {
                var box = this.dragImg;//// document.getElementById('geshang')///移动克隆的对象
