Vue+ElementUI之Tree的使用 Vue+ElementUI之Tree如何使用
CnNoter 人气:0想了解Vue+ElementUI之Tree怎样使用的相关内容吗，CnNoter在本文为您仔细讲解Vue+ElementUI之Tree的使用的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：Vue,ElementUI,Tree，下面大家一起来学习吧。
Vue+ElementUI之Tree的使用，供大家参考，具体内容如下
前端代码
<template>
<div>
<el-dialog title="终端通讯录" :visible.sync="isOpen" class="el-dialog-mini">
<div class="forms-menu-con">
<!--
check-on-click-node:设置是否在选汉字的时候,复选框也选中
props:定义节点和自己提供字段的匹配(例:名称对应数据库查询出来的name属性)
data:Tree中的数据,其中字段可以自定义,可以多添加业务字段,再点击的时候调用函数获取该值
node-key:唯一,意味着选中节点的时候使用哪个字段作为唯一标识
render-content:内容渲染,如果想要在树菜单上添加图标等样式使用这个属性,配置一个渲染函数即可
check-change:当复选框状态改变时候,触发次函数,这个主要用来做单选操作,和业务处理使用
show-checkbox:显示复选框
highlight-current:高亮显示选中节点
check-strictly:在显示复选框的情况下,是否严格的遵循父子不互相关联的做法,默认为 false
-->
