拖动的元素在鼠标按下时通过时间差给元素添加一个属性（drag-flag），若超过规定时间则认为是在拖拽，属性设置为true, 否则设置为false。点击方法中通过获取这个属性判断是否要执行点击后的指令。

html:

<div class="drag-area">
   <div v-if="isShowHelp" class="help-control"
     ref="helpControl"
     draggable="true"
     @mousedown.stop="moveLineFun"
     @click="openWin">
     帮助
   </div>
 </div>

JS：

openWin() {
   // 解决鼠标拖拽与点击事件冲突
   const isDrag = this.$refs.helpControl.getAttribute('drag-flag');
   if (isDrag === 'true') {
     return false;
   }
   this.setIsOpenDocWin(true);
 },
 // 拖拽监听鼠标按下
moveLineFun(e) {
  const { target } = e;
  const moveBoxObj = document.getElementsByClassName('drag-area')[0]; // 最大的框，自带相对定位属性
  const moveObj = document.getElementsByClassName('help-control')[0]; // 移动的元素
  const moveBoxObjMaxWidth = moveBoxObj.clientWidth; // 得到点击时该元素所在大容器的宽
  const moveBoxObjMaxHeight = moveBoxObj.clientHeight; // 得到点击时该元素所在大容器的高
  const moveLineObjOffsetLeft = moveObj.offsetLeft; // 得到点击时该元素的左边距
  const moveLineObjOffsetTop = moveObj.offsetTop; // 得到点击时该元素的上边距
  const moveStartX = e.clientX; // 得到当前鼠标点击的x位置
  const moveStartY = e.clientY; // 得到当前鼠标点击的x位置
  const leftMin = 0;
  const leftMax = moveBoxObjMaxWidth - moveObj.clientWidth; // 左边距最大值
  const topMax = moveBoxObjMaxHeight - moveObj.clientHeight; // 上边距最大值
  // 解决鼠标拖拽与点击事件冲突：时间差
  moveObj.setAttribute('drag-flag', false);
  const dragStartTime = new Date().getTime();
  document.onmousemove = () => {
    const dragEndTime = new Date().getTime();
    if (dragEndTime - dragStartTime > 200) {
      target.setAttribute('drag-flag', true);
    }
  };

  // 绑定鼠标移动时的计算
  function moveFun(e1) {
    e1.preventDefault();
    const mouseMoveDistance = e1.clientX - moveStartX; // 鼠标滑动距离（正则是往右；负则是往左）
    const mouseMoveDistanceY = e1.clientY - moveStartY; // 鼠标滑动距离（正则是往下；负则是往上）
    moveObj.style.positon = 'absolute'; // 给元素添加绝对定位属性
    let styleLeft = moveLineObjOffsetLeft + mouseMoveDistance; // 左边距 = 元素初始（左边距）位置 + 鼠标滑动的距离
    let styleTop = moveLineObjOffsetTop + mouseMoveDistanceY; // 左边距 = 元素初始（左边距）位置 + 鼠标滑动的距离
    console.log('move');
    if (styleLeft <= leftMin) {
      styleLeft = leftMin;
    } else if (styleLeft > leftMax) {
      styleLeft = leftMax;
    }
    if (styleTop <= moveObj.clientHeight) {
      styleTop = 0;
    } else if (styleTop > topMax) {
      styleTop = topMax;
    }
    moveObj.style.left = `${styleLeft}px`; // 赋值拖动的线的左边距离
    moveObj.style.top = `${styleTop}px`; // 赋值拖动的线的左边距离
  }
  // 取消计算绑定
  function stopFun() {
    document.removeEventListener('mousemove', moveFun); // 取消监听事件，鼠标开始移动
    document.removeEventListener('mouseup', stopFun); // 取消监听事件，鼠标停止移动
  }
  clearTimeout(this.clickTimeId);
  document.addEventListener('mousemove', moveFun); // 添加监听事件，鼠标开始移动
  document.addEventListener('mouseup', stopFun); // 添加监听事件，鼠标停止移动
},
},

场景：帮助按钮吸附在页面右侧，hover按钮时展开，点击时展开浮窗文档，可对按钮进行右侧的竖向拖拽
