Install and basic usage

一个可以帮助你控制并管理拖拽流程的开箱即用的VUE组件(vue2)

$ npm i -s adrag

Register the component:

import {fragment,provider} from "adrag";
Vue.component('provider', provider)
Vue.component('fragment', fragment)

Use the component:

<template>
  <div>
    <div @click="aiderComputed">aider开启</div>
    <div @click="aiderClear">aider关闭</div>
    <div @click="undo">undo</div>
    <div @click="zoomOut">放大</div>
    <div @click="zoomIn">缩小</div>
    <fragment
        tag="1"
        render-key="123"
        :put-component="components[0]"
        :modal-component="components[2]"

refs function of provider

• provider内的所有内容是不可见的，当你需要修改内容时，你需要通过$refs调用函数的方式来达到目的
• 数据结构

 /*
         * x x,
         * y y,
         * w 宽,
         * h 高,
         * f 聚焦,
         * z 层级,
         * c 组件,
         * m 弹窗组件
         * v 显示,
         * id 标识
         * renderData 数据
         * shadow 链接效果
         * firstMounted 组件是否需要渲染，当你渲染的组件为图表时,这会很实用，你在组件的mounted状态内通过该属性来判断是否需要渲染，从而有效规避数据同步时组件数组指向变化导致的组件多次挂载渲染
         */
        interface render {
             x:number, 
             y:number,
