Ajax入门事例

Ajax入门例子

index.jsp

?
struts_config.xml
?
TempAction.java
@Overridepublic ActionForward execute(ActionMapping mapping, ActionForm form,HttpServletRequest request, HttpServletResponse response)throws Exception {PrintWriter pw = response.getWriter();SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");String today = df.format(new Date());//(1)这里的print就是index.jsp中要获取的responseTextpw.print(today);//(2)记得要flushpw.flush();//(3)如果是ajax的请求，这里不要返回页面，不然会将整个页面html源码赋值到responseText中return null;}
