基于zTree的常用成员管理树图级联选择(仿穿梭框功能)

广州这几天的天气异常寒冷，前几天搞一个系统需要实现菜单管理，而菜单管理页则需要涉及到给用户授权访问菜单，因此需要选择相应的可访问成员，之前在基于elementui的后台管理系统中用过它的树图组件，觉得挺不错的，因此决定自己封装一个jquery的ztree成员管理树图，在这淘宝双十二的夜晚，闲暇之余记录下自己的学习点滴------------前言

源码地址：https://github.com/applebring/zTree-Plugin-for-jquery.git

运行：目前为静态数据，直接运行index.html即可

插件功能：可实现对左侧树图节点的搜索，可实现选择左侧树图成员到右侧框中，可实现右侧数据的删除，可实现数据的初始化

基本界面如下：

直接上代码，注释也已经很清晰

HTML:

<body>
	<h1>基于zTree树部门成员选择器插件</h1>
	<div class="content_wrap">
		<div class="zTreeDemoBackground left">
			<div class="input-search">
				<input type="text" placeholder="输入关键字查询" id="filter-text" class="empty" /><span style="color:red;font-size:12px;position:absolute;left:0;right:0;top:40px;display:none;"
				 class="no-data">查找不到结果~</span>
			</div>
			<div class="tree-content">
				<ul id="treeDemo" class="ztree"></ul>
			</div>
		</div>
		<div class="right">
			<ul class="choose-content">
			</ul>
		</div>
	</div>
	<br/>
	<button id="btn-reset">重置数据项</button>&nbsp;<button id="btn-confirm-id">获取选中数据(id)</button>&nbsp;<button id="btn-confirm-obj">获取选中数据(obj)</button>
	<div class="choose-data">
		<div class="choose-data">
			<span>当前选中数据为:</span><br/>
			<div class="data">暂无数据</div>
		</div>
</body>

未封装为插件前的JAVASCRIPT（ps：搜索关键字可根据需要搜索zNode相应字段，本次搜索是通过name字段搜索，如需搜索到父级文字可搜索zNodes中的searchdata字段）
