用树展示上下级关系-jquery+ztree+json的运用之获取选中的信息

继之前的一篇 用树展示上下级关系-jquery+ztree+json的运用 


这一篇主要是获取选中的内容。



选中内容后会在文本框进行显示。

具体实现代码

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <base href="<%=basePath%>">
    
    <title>My JSP 'tree.jsp' starting page</title>
