ajax调用后盾并返回页面进行操作

JSP 部分：

<script type="text/javascript">

   initNoBid();//得到No Bid的任务数
  <%}%>
  $("#monthTree").youiTree();
  $("#monthTree").show();
 });
 //得到My solution的任务数
 function initMysolution(){
   var url="<%=path%>/order/orderListAction.do?method=findMySolutionCount";//caomeng:2011-10-10
