Jquery UI 1.3 (组合树 - ComboTree ) 集成Wabacus4.1 集成Spring 代码剖析
使用时，请下载需要Jquery ui包进行配置
combotree.js 的代码，可以不用修改, 只是Wabacus中的编辑少量配置一下即可，此例子只进行了2级的菜单拼接，如需修改，只需将方法修改成递归拼接即可
如：
首先combotree.js代码
var dataurl,valuefield,textfield;
/**
* 加载树形下拉框
*/
function loadComboTree(){
dataurl = $('input.easyui-combotree').attr("dataurl");
valuefield = $('input.easyui-combotree').attr("valuefield");
textfield = $('input.easyui-combotree').attr("textfield");
//alert(dataurl);
$('input.easyui-combotree').combotree({
url:dataurl, //data : json,
valueField : valuefield,
textField : textfield,
editable: false, //定义用户是否可以直接输入文本到选择框默认false
animate:true, //展开/折叠节点的时候是否显示效果
onClick : function(node) {
//alert(node.id+"___"+node.text);
$('input.easyui-combotree').val(node.id); // 赋值
},
onSelect : function(node) {
//返回树对象
var tree = $(this).tree;
//选中的节点是否为叶子节点,如果不是叶子节点,清除选中
var isLeaf = tree('isLeaf', node.target);
if (!isLeaf) {
//清除选中
$('input.easyui-combotree').combotree('clear');
}
},
onLoadSuccess: function(node, data) {
var id = $('input.easyui-combotree').val();
var v_t = $('input.easyui-combotree').combotree('tree');
if(id == null || id == 'undefined' || id.trim() == '') return;
//alert(id);
var t = v_t.tree('find',id); // 查找，并选中当前
if(t != null && t!=""){
v_t.tree('select', t.target);
}
},
onLoadError: function(){
$(this).append("<li>出错页面</li>");
}
});
}
一 page和report
<page id="edit_plansolution" js="/myproject/jqueryui/js/jquery-1.10.1.min.js,/myproject/jqueryui/js/jquery.easyui.min.js,/myproject/jqueryui/js/combotree.js" css="/myproject/jqueryui/css/easyui.css,/myproject/jqueryui/css/icon.css" > <report id="edit_detail" title="测试" onload="loadComboTree">
二、编辑列
<col column="eventype" label="事故类型："> <inputbox jsvalidate="isNotEmpty(#label#列不能为空)" styleproperty="class='easyui-combotree' dataurl='SelectTree.jsp' valuefield='id' textfield='text' style='250px'" /> </col>
三、Service
Web.xml配置
<resource-ref>
<description>DB Connection</description>
<res-ref-name>jdbc/naframework</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
Spring配置
<?xml version="1.0"encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-2.5.xsd"
default-lazy-init="true">
<!-- 数据源配置,在生产环境使用应用服务器的数据库连接池 -->
<bean id="springDSN"class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName"value="java:comp/env/jdbc/naframework"/>
</bean>
<bean id="jdbcTemplate"class="org.springframework.jdbc.core.JdbcTemplate"abstract="false" lazy-init="false"autowire="default"dependency-check="default">

</bean>
<!-- 事务管理器配置,单数据源事务 -->
<bean id="transactionManager"class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory"ref="sessionFactory"/>
</bean>
</beans>
JAVA配置
privateJdbcTemplate jdbcT = (JdbcTemplate) SpringUtil.getBean("jdbcTemplate");
/**
* 拼接成json类型 事故类型
* @author 刘仁奎
* @return
*/
publicString getJSONData(){
// 查询一级节点
String sql="select * from category where categorytype='accidclass' and categorylevel='1' order by categorycode";
List list=jdbcT.queryForList(sql);
StringBuffer json=newStringBuffer("[");
String data="",d_2="";
if(list!=null&& list.size()>0){
for(inti=0; i<list.size();i++){
Map v_map = (Map)list.get(i);
json.append("{"id":""+v_map.get("CATEGORYCODE").toString().trim()+"",");
json.append(""text":""+v_map.get("CATEGORYNAME").toString().trim()+""");
if(v_map.get("CATEGORYLEVEL") != null&& v_map.get("CATEGORYLEVEL").toString().trim().equals("1")){// 判断是否是父节点，赋图标
// 拼接2级子节点
String sql_2="select * from category where categorytype='accidclass' and categorylevel='2' and parentcode='"+v_map.get("CATEGORYCODE")+"' order by categorycode";
List v_l=jdbcT.queryForList(sql_2);
if(v_l.size()>0){
json.append(","children":");
//System.out.println("********************"+sql_2+"***********************");
StringBuffer child_json=newStringBuffer("[");
for(intj=0; j<v_l.size();j++){
Map v_m = (Map) v_l.get(j);
child_json.append("{"id":""+v_m.get("CATEGORYCODE").toString().trim()+"",");
child_json.append(""text":""+v_m.get("CATEGORYNAME").toString().trim()+""},");
//System.out.println("_____子节点：_"+v_m.get("CATEGORYCODE")+"__"+v_m.get("CATEGORYNAME")+"___________");
}
if(child_json.lastIndexOf(",") != -1){
d_2 = child_json.substring(0,child_json.lastIndexOf(","))+"]},";
json.append(d_2);
}
}else{ // 如果没有子节点
json.append("},");
}
}
}
}
data=json.substring(0, json.length()-1)+"]";
System.out.println(data);
returndata;
}
我这里的Servlet使用了jsp代替
<%@ page language="java" pageEncoding="UTF-8"%>
<%@ page contentType="text/html; charset=UTF-8"%>
<%@ page import="com.nasoft.jdbc.sysmanager.CategoryDao" %>
<%
/**
* 应急预案，事故类型下拉框树
*/
CategoryDao std = new CategoryDao();
//String json = std.getJSONData();
// String json="[{"id":1,"text":"Folder1","iconCls":"icon-ok","children":[{"id":2,"text":"File1"},{"id":3,"text":"Folder2","state":"open","children":[{"id":4,"text":"File3","iconCls":"icon-reload"}]}]},{"text":"Languages","state":"closed","children":[{"id":"j1","text":"Java"},{"id":"j2","text":"C#"}]}]";
//System.out.println(json);
out.print(json);
