本人是采用SSH架构搭建的项目
问题一:存在的问题是? 获取的json数据 不显示。
UserAction代码
/** * 获取用户所有task列表 * * @param mapping * @param form * @param request * @param response * @return * @throws Exception */ public ActionForward getUserTasksList(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception { String userId = request.getParameter("userId"); String weekId = request.getParameter("weekId"); System.out.println("userId:" + userId + ",weekId:" + weekId); List<STaskOfweek> list = taskTotalService .queryTaskOfweekListByUserIdAndWeekId(Integer.valueOf(weekId), Integer.valueOf(userId)); System.out.println("list.size:" + list.size()); // request.setAttribute("userTaskList", userTaskList); List<UserTask> userTaskList = new ArrayList<UserTask>(); for (int i = 0; i < list.size(); i++) { STaskOfweek sow = list.get(i); UserTask ut =new UserTask(); ut.setTaskId(sow.getTaskId()); ut.setTaskName(sow.getTaskName()); ut.setWeekId(sow.getSWeek().getWeekId()); ut.setByAssessmanId(sow.getByAssessmanId()); userTaskList.add(ut); } Map map = new HashMap(); map.put("userTaskList", userTaskList); JSONArray jo = JSONArray.fromObject(map); System.out.println("str:"+jo.toString()); response.getWriter().write(jo.toString()); return null; }

JSP页面代码
<script type="text/javascript"> var root = "${pageContext.request.contextPath}"; $(document).ready(function(){ $("#displayTable").click(function(){ var url=root+"/getUserTasksList.do"; jQuery.post(url,"weekId=14&userId=30",function(data){ var m="<table border='1'>"; //var items=data.userTaskList;//在此若取不到值可用var items = data[0];代替 //var items=eval(data.userTaskList); var items = eval(data); for(var i=0;i<items.length;i++){ var task=items[i]; m=m+"<tr><td>"+task.taskName+"</td><td>"+task.taskId+"</td></tr>"; } m+="</table>"; document.getElementById("myTable").innerHTML=m; },'json'); }); }); </script> <body> <input type="button" value="显示我的表格" id="displayTable"/> ?????????????????? ?????????????????? <div id="myTable">测试json数据显示</div> </body>
?感谢群里所有好心的朋友,我的问题最终得到解答。
贴出来,作个参考。
