Jquery easyui 实现动态树

在上篇文章给大家介绍了jquery中EasyUI实现异步树，本文给大家介绍jquery easyui实现动态树。

首先是在jsp页面中引入相关的js文件
在body中加入流程列表，通过后天拼接json数据
具体内容请看下面代码详情吧。

首选在jsp页面中引入相关的js

添加script

在body中加入

 
  

  
流程列表
  
 

后台拼接json数据

package com.aegon_cnooc.oa.formconfig.action;
import java.io.PrintWriter;
import java.util.List;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import com.aegon_cnooc.framework.base.action.BaseAction;
import com.aegon_cnooc.oa.formconfig.service.FormConfigService;
import com.aegon_cnooc.oa.ibatis.to.TuOafWfTO;
import com.aegon_cnooc.oa.ibatis.to.TuOafWfnodesTO;
import com.aegon_cnooc.util.StringUtil;
/**

public class LoadWfNodesAction extends BaseAction{
 private FormConfigService formConfigService;
 public ActionForward executeAction(ActionMapping mapping, ActionForm form,
   HttpServletRequest request, HttpServletResponse response)
   throws Exception {
  String wfId=request.getParameter("wfId");
  String jsonstr = "[";
  if(StringUtil.isNotEmpty(wfId)&&"0".equals(wfId)){
   List wfList=formConfigService.findWf();
   for(int i=0;i"+wfTo.getWfname()+"\",\n" +  
    "  \"state\":\"closed\"\n" + 
    " },";
   }
   int end=jsonstr.length()-1;//去掉最后一个逗号
   String json=jsonstr.substring(0,end);
   json=json+"]";
  response.setContentType("application/json;charset=gbk");
  response.setCharacterEncoding("gbk");
  PrintWriter pw = response.getWriter();
  pw.write(json);
  pw.flush();
  }else{
  List wfNodes=formConfigService.findWfNodesById(wfId);
   for(int i=0;i"+wfNodesTo.getGenstepname()+"("+wfNodesTo.getNodeid()+")\",\n" +  
    "  \"state\":\"closed\"\n" + 
    " },";
   }
   int end=jsonstr.length()-1;//去掉最后一个逗号
   String json=jsonstr.substring(0,end);
   json=json+"]";
  response.setContentType("application/json;charset=gbk");
  response.setCharacterEncoding("gbk");
  PrintWriter pw = response.getWriter();
  pw.write(json);
  pw.flush();
  }
  return null;
 }
 public void setFormConfigService(FormConfigService formConfigService) {
  this.formConfigService = formConfigService;
 }
}

下面一段代码是EasyUI Jquery 动态加载树，点击节点加载
