ajax如何实现页面局部跳转与结果返回

<input type="button" class="btn" value="提报" name="submit4" onClick="tibao();">

function tibao(){
var id='';
var URL = <select:link page="/smokeplan.do"/>+id;
  $.ajax({url: URL, 
    　　type: 'GET',
    　　success: function(result) {
           alert(result);
        }
  });
}

//提报
    public void Tibao(ActionMapping mapping, ActionForm form,
        HttpServletRequest request, HttpServletResponse response) throws Exception {
      String idset=request.getParameter("idset");
      CallHelper helper = initializeCallHelper("L_SmokeBoxtibaoWLDan", form,request, false);
      helper.setParam("bill_ids",idset);
      helper.setParam("personid",getPersonId(request));
      helper.execute();
      PrintWriter write = response.getWriter();
      write.print(helper.getOutput("message"));
      write.close();
    }

function doGuahao()
{
 if(checkdata())
 {
 if(document.form1.result_flag.value=="0")
 {
  return false;
 }
 else
 {
  if(document.form1.checktype.value=="danganhao")
  {
  form1.action = "<%=formAction%>";
  form1.submit();
  }
  if(document.form1.checktype.value=="xingming")
  {
  form1.action = parent.left.url2;
  form1.submit();
  }
  if(document.form1.checktype.value=="shenfenzheng")
  {
  form1.action = "<%=formAction%>";
  form1.submit();
  }
 }
 }
