vue 元素拖动，快捷方便，已解决

1.vDrag.js

import Vue from "vue";

Vue.directive("Drag", (el) => {
  const moveEl = el;
  let flag = false;
  const mouseDown = (e) => {
    flag = true;
    let X = e.clientX - el.offsetLeft
    let Y = e.clientY - el.offsetTop
    const move = (e) => {
      if (flag) {
        el.style.cursor = 'move';
        el.style.marginLeft = '0px';
        el.style.marginTop = '0px';
        el.style.left = e.pageX - X + 'px';
        el.style.top = e.pageY - Y + 'px';
      }
    }
    document.addEventListener('mousemove', move);
    document.addEventListener('mouseup', (e) => {
      document.removeEventListener('mousemove', move);
    });
  }
  moveEl.addEventListener('mousedown', mouseDown);
})

2.加上这两个属性内容

元素随意拖动

出现问题：出现鼠标mouseup事件监听bug，导致鼠标释放事件和元素和鼠标粘在一起

解决方法:

改为false即可解决问题
