第一次使用jqgrid问题
从网上找了N个例子试用,每次都是在前台firebug中都已经可以看到传过来josn数据了,但是在jqgrid中就是没有数据。
今天把josn数据中的单引号,全部替换成双引号,数据终于显示出来了。
jqgrid居然不识别单引号!!!!!!
这个足足搞了三天,居然是因为这个。。。 郁闷!

java后台代码如下:
随便写的测试代码,比较乱。。。
public void getEvents(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception { StringBuffer str = new StringBuffer(); //定义时间格式 DateFormat format1 = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); try { List eventList = eventService.getEvents(); str.append("{\"events\":["); if (eventList != null && eventList.size()> 0) { //for(Iterator iter = eventList.iterator();iter.hasNext();){ for(int i=0;i<10;i++){ Event event = (Event)eventList.get(i); str.append("{\"eventID\":"+"\""+event.getEventID()+"\","); str.append("\"cuid\":"+"\""+event.getCuid()+"\","); str.append("\"eventTime\":"+"\""+format1.format(event.getEventTime())+"\","); str.append("\"severity\":"+"\""+event.getSeverity()+"\","); str.append("\"eventType\":"+"\""+event.getEventType()+"\","); String dec = stringFilter(event.getDescription()); str.append("\"description\":"+"\""+dec+"\"}"); /* if(iter.hasNext()){ str.append(","); }*/ if(i<9){ str.append(","); } } } //str.substring(0,str.length()-1); str.append("],\"page\":1,\"rows\":10,\"total\":10}"); } catch(Exception e){ logger.error("获取告警事件发生异常!",e); } response.setContentType(" text/josn;charset=utf-8 "); PrintWriter out = response.getWriter(); out.println(str); out.flush(); }
接收到的josn数据:
{ "events":[ {"eventID":"1298878203692","cuid":"HP-3.125","eventTime":"2011-02-28 15:30:03","severity":"3","eventType":"Probe","description":" Connection refused"}, {"eventID":"1298878202225","cuid":"HP-3.125","eventTime":"2011-02-28 15:30:02","severity":"3","eventType":"Probe","description":"Connection refused"}, {"eventID":"1298878201201","cuid":"HP-3.125","eventTime":"2011-02-28 15:30:01","severity":"3","eventType":"Probe","description":" Connection refused"}, {"eventID":"1298877903783","cuid":"HP-3.125","eventTime":"2011-02-28 15:25:03","severity":"3","eventType":"Probe","description":"Connection refused"}, {"eventID":"1298877902365","cuid":"HP-3.125","eventTime":"2011-02-28 15:25:02","severity":"3","eventType":"Probe","description":" Connection refused"}, {"eventID":"1298877901326","cuid":"HP-3.125","eventTime":"2011-02-28 15:25:01","severity":"3","eventType":"Probe","description":"Connection refused"}, {"eventID":"1298867776540","cuid":"HP-3.125","eventTime":"2011-02-28 12:36:16","severity":"3","eventType":"Probe","description":"No route to host"}, {"eventID":"1298867776521","cuid":"Dell-31","eventTime":"2011-02-28 12:36:16","severity":"3","eventType":"Probe","description":"Connection timed out"}, {"eventID":"1298867776463","cuid":"HP-3.125","eventTime":"2011-02-28 12:36:16","severity":"3","eventType":"Probe","description":"Connection timed out"}, {"eventID":"1298867774532","cuid":"HPGroup","eventTime":"2011-02-28 12:36:14","severity":"3","eventType":"Probe","description":"Connection timed out"}], "page":1,"rows":10,"total":10 }
把这里边的双引号换成单引号数据就会无法显示!!!诡异。
