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"},

}
把这里边的双引号换成单引号数据就会无法显示！！！诡异。
