JSP中的幾個實用函數（時間判斷/IP擷取/累計次數/視頻播放等）

<%@ page import="java.util.Calendar"%>
<%! private int count=0;
    public int getCount()
   {
      return ++count;
   }
%><b>&nbsp;
<% Calendar calendar=Calendar.getInstance();
   int hourOfDay=calendar.get(Calendar.HOUR_OF_DAY);
   if(hourOfDay<=12){
%>Good morning!
<%}else if(hourOfDay<=18){
%>Good afternoon!
<%}else {
%>Good evening!
<%}%>
This is the <font color=red size=+1><%=getCount()%></font> time this page has been visited!</b>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Your IP:<%=request.getRemoteAddr()%>

播放視頻的！
