jQuery拖动树范例

jQuery拖动树实例
1、树根节点

<ul id='root'><span>所有群组</span><ul><%=topGroupTree%></ul></li></ul>

2、值topGroupTree

UsergroupInfo ugInfo = new UsergroupInfo();RelationguInfo rInfo = new RelationguInfo();//获取一级群组列表String topGroupTree = ugInfo.getTopLevelGroup();

3、方法getTopLevelGroup

/** * 获取一级群组 * @return */public String getTopLevelGroup(){String group_tree = "";String sql = "select group_id, group_name from zl_usergroup where group_level='1'";ArrayList result = new DbexecuteDAO().selBizQuery(sql);if(null != result){for (int i = 0; i < result.size(); i++) {HashMap map = (HashMap) result.get(i);String group_id = "",group_name="";if(null != map){if(null != map.get("group_id")){group_id = map.get("group_id").toString();}if(null != map.get("group_name")){group_name = map.get("group_name").toString();}group_tree += "<li class='colse' id='"+group_id+"'><span>"+group_name+"</span><ul class='ajax'><li id='ajaxli'>{url:ajaxGroup.jsp?group_id="+group_id+"}</li></ul></li>";}}}return group_tree;}

4、ajaxGroup.jsp

<%@ page language="java" import="java.util.*" pageEncoding="gbk"%>
<%@ page import="com.crm.usergroup.UsergroupInfo" %>

<%//获取参数String groupId = "";if(null != request.getParameter("group_id")){groupId = request.getParameter("group_id");}UsergroupInfo ugInfo = new UsergroupInfo();String groupString = ugInfo.getChildgroupById(groupId);out.write(groupString); %>

5、ajaxGroupUsers.jsp

<%@ page language="java" import="java.util.*" pageEncoding="gbk"%><%@ page import="com.crm.relationgu.RelationguInfo" %><%//获取参数String groupId = "";if(null != request.getParameter("group_id")){groupId = request.getParameter("group_id");}RelationguInfo rInfo = new RelationguInfo();String groupUsersString = rInfo.getGroupUsersById(groupId);out.write(groupUsersString); %>

6、方法getGroupUsersById

/** * 获取指定组的成员串 * @param group_id */public String getGroupUsersById(String group_id){String usersString = "";ArrayList result = getUserByGroupId(group_id);if(result != null && result.size()> 0){for (int i = 0; i < result.size(); i++) {HashMap map = (HashMap) result.get(i);String user_id = "",user_name="";if(null != map){if(null != map.get("user_id")){user_id = map.get("user_id").toString();}if(null != map.get("user_name")){user_name = map.get("user_name").toString();}usersString += "<li id='"+user_id+"'><span class='text'>"+user_name+"</span></li>";}}}else{usersString = "<li id='' style='display:none;'></li>";}return usersString;}
