Server Side Includes:

Experienced JavaScript programmers know that code reuse is good. Experienced JavaScript programmers also know that JavaScript functions are data types.

So, we should be able to store a JavaScript function inside a Session Variable or an Application Variable, right? Unfortunately, no. The way to reuse JavaScript functions across many pages is to use SSI: Server Side Includes.

<%@LANGUAGE="JavaScript"%>
<HTML>
<HEAD>
<!--#include file="script13a.asp"-->
<TITLE><% Response.Write( whatTimeIsIt() ) %> </TITLE>
</HEAD>
<BODY>
<%
Response.Write("The date and time are " + DateTime + "<BR><BR>\r")
Response.Write("Tomorrow's date is " + Tomorrow + "<BR><BR>\r")
Response.Write("Tomorrow will be a " + findDayOfWeek(Tomorrow) + "\r")
%>
</BODY>
</HTML>

Click Here to run the script in a new window.

Look at the code for script13.asp. It calls for an include file via this line:  I'll let you see the include file in a moment. But first, I reprinted the client-side code directly below.

<HTML>
<HEAD>

<TITLE>10:57:20 AM </TITLE>
</HEAD>
<BODY>
The date and time are 4/11/2003 10:57:20 AM<BR><BR>
Tomorrow's date is 4/12/2003<BR><BR>
Tomorrow will be a Saturday

</BODY>
</HTML>

The final HTML code looks so nice and simple. You'd never know that the Date() object had been torn down and put back together. Below is the include file.

<%
function whatTimeIsIt()
	{
	var m=new Date()
	var minute=m.getMinutes()
	var second=m.getSeconds()
	var ampm=false

	if (minute >=0 && minute < 10)
		{
		minute=("0" + minute)
		}
	if (second >= 0 && second < 10 )
		{
		second=("0" + second)
		}
	var hours=m.getHours()
	if (hours > 12)
		{
		ampm=true
		hours=hours-12
		}
	if (hours==12)
		{
		ampm=true
		}
	if (hours == 0)
		{
		hours=hours+12
		ampm=false
		}
	if (ampm)
		{
		ampm=" pm"
		}
	else
		{
		ampm=" am"
		}
	var myTime=hours + ":" + minute + ":" + second + ampm
	return myTime;
	}
var DateTime = new Date();
var Month = (DateTime.getMonth() + 1) + "/";
var Day = DateTime.getDate() + "/";
var Year = DateTime.getFullYear();
var DateTime = Month + Day + Year + " " + whatTimeIsIt();

var Tomorrow=new Date()
Tomorrow.setDate(Tomorrow.getDate() + 1)
Month = (Tomorrow.getMonth() + 1) + "/"
Day = Tomorrow.getDate() + "/" 
Year = Tomorrow.getFullYear()
Tomorrow = Month + Day + Year

function findDayOfWeek(DateInQuestion)
	{

	// format for DateInQuestion is mm/dd/yyyy or m/d/yyyy 
	// and presumes the /'s are present.	

	myRegExp=/\d{1,2}\//
	myMonth=(parseInt(DateInQuestion.match(myRegExp)) -1)

	myRegExp=/\/\d{1,2}\//
	myDay=new String(DateInQuestion.match(myRegExp))
	myDay=parseInt( myDay.substring(1,myDay.length) )

	myRegExp=/\/\d{4}/
	myYear=new String(DateInQuestion.match(myRegExp))
	myYear=parseInt( myYear.substring(1,myYear.length) )

	DateInQuestion=new Date(myYear,myMonth,myDay)
	
	DayOfWeek=new Array
	DayOfWeek[0]="Sunday"
	DayOfWeek[1]="Monday"
	DayOfWeek[2]="Tuesday"
	DayOfWeek[3]="Wednesday"
	DayOfWeek[4]="Thursday"
	DayOfWeek[5]="Friday"
	DayOfWeek[6]="Saturday"
	DayOfWeek=DayOfWeek[DateInQuestion.getDay()]

	return DayOfWeek;
	}
%>

Imagine that you had 50 pages that all need whatTimeIsIt(), findDayOfWeek(), DateTime, and Tomorrow. You wouldn't want 50 different copies of these functions and variables. No, you would rather have a single copy of these items so that you could manipulate the single copy and execute your updates to all 50 pages at once.

Now you know how to do that.

Moving Forward:

This concludes Section 03. Next up Server and Error objects in Section 04.

《魔兽世界》大逃杀！60人新游玩模式《强袭风暴》3月21日上线

暴雪近日发布了《魔兽世界》10.2.6 更新内容，新游玩模式《强袭风暴》即将于3月21 日在亚服上线，届时玩家将前往阿拉希高地展开一场 60 人大逃杀对战。

艾泽拉斯的冒险者已经征服了艾泽拉斯的大地及遥远的彼岸。他们在对抗世界上最致命的敌人时展现出过人的手腕，并且成功阻止终结宇宙等级的威胁。当他们在为即将于《魔兽世界》资料片《地心之战》中来袭的萨拉塔斯势力做战斗准备时，他们还需要在熟悉的阿拉希高地面对一个全新的敌人──那就是彼此。在《巨龙崛起》10.2.6 更新的《强袭风暴》中，玩家将会进入一个全新的海盗主题大逃杀式限时活动，其中包含极高的风险和史诗级的奖励。
《强袭风暴》不是普通的战场，作为一个独立于主游戏之外的活动，玩家可以用大逃杀的风格来体验《魔兽世界》，不分职业、不分装备（除了你在赛局中捡到的），光是技巧和战略的强弱之分就能决定出谁才是能坚持到最后的赢家。本次活动将会开放单人和双人模式，玩家在加入海盗主题的预赛大厅区域前，可以从强袭风暴角色画面新增好友。游玩游戏将可以累计名望轨迹，《巨龙崛起》和《魔兽世界：巫妖王之怒经典版》的玩家都可以获得奖励。
