vue实现盒子的拖拽移动

代码如下（示例）：创建js文件

//创建一个js文件 directive.js
import Vue from "vue";
Vue.directive("drag", {
  bind: function (el) {
    let odiv = el;
    odiv.style.position = "fixed";
    odiv.onmousedown = (e) => {
      let disX = e.clientX - odiv.offsetLeft;
      let disY = e.clientY - odiv.offsetTop;
      document.onmousemove = (e) => {
        let left = e.clientX - disX;
        let top = e.clientY - disY;
        odiv.style.left = left + "px";
        odiv.style.top = top + "px";
      };
      document.onmouseup = () => {
        document.onmousemove = null;
        document.onmouseup = null;
      };
    };
  },
});

2.main.js引入

import './view/sm/directive'
