tree-transfer

树形穿梭框

简介

树形穿梭框组件,基于 vue + element-ui,使用场景:经营类目、部门选择等场景。使用前请先确认安装并注册 element-ui。

安装

npm install ele-tree-transfer -S

挂载方式

1. 局部挂载:

import { TreeTransfer } from "ele-tree-transfer";

export default {
  components: {
    TreeTransfer,
  },
}

2. 全局挂载:

在 main.js 文件中加入代码:

import TreeTransfer from "ele-tree-transfer";

Vue.use(TreeTransfer);

快速启动
