ASP scripts are surrounded by <% and %>. To write some output to a browser:
ASP脚本可以写在“<%和%>”之中,举例:
<html>
<body>
<% response.write("Hello World!") %>
</body>
</html>
The default language in ASP is VBScript. To use another scripting language, insert a language specification at the top of the ASP page:
ASP默认的语言是ASP和VBScript;如果你希望使用另外一种脚本语言,你必须在ASP页面的开头插入一段语句,例:
<%@ language="javascript" %>
<html>
<body>
<%
....
%>
Request.QueryString is used to collect values in a form with method="get". Information sent from a form with the GET method is visible to everyone (it will be displayed in the browser's address bar) and has limits on the amount of information to send.
Request.QueryString是用来收集用“get”方式传输的表单变量的。通过“Get”方式发送的变量信息对任何人来说都是可见的(他将显示在浏览器的地址栏里),但是,他对发送信息的长度有限制。
Request.Form is used to collect values in a form with method="post". Information sent from a form with the POST method is invisible to others and has no limits on the amount of information to send.
Request.Form是用来收集用“post”方式传输的表单变量的。通过“post”方式发送的变量信息对别人来说都是不可见的,然而,它对发送信息的长度没有限制。
A cookie is often used to identify a user. A cookie is a small file that the server embeds on the user's computer. Each time the same computer requests for a page with a browser, it will send the cookie too.
Cookie通常是用来确认用户身份的。Cookie是通过服务器发送到用户计算机中的一小段文件。每次,当相同的计算机通过浏览器请求页面时,他也同样会把Cookie发送过去。
The Response.Cookies command is used to create cookies:
Response.Cookies命令是用来建立Cookies的:
<%
Response.Cookies("firstname")="Alex"
Response.Cookies("firstname").Expires="May 10,2002"
%>
Note: The Response.Cookies command must appear BEFORE the <html> tag!
注意:Response.Cookies命令必须写在<html>标签之前。
The "Request.Cookies" command is used to retrieve a cookie value:
Request.Cookies命令是用来获取Cookie值的:
<%
fname=Request.Cookies("firstname")
response.write("Firstname=" & fname)
%>
You can insert the content of one ASP file into another ASP file before the server executes it, with the #include directive. The #include directive is used to create functions, headers, footers, or elements that will be reused on multiple pages
你可以使用#include在服务器执行某个ASP文件之前将这个ASP文件插入到另外一个ASP文件内。
Syntax:
语法:
<!--#include virtual="somefile.inc"-->
or
<!--#include file ="somefile.inc"-->
Use the virtual keyword to indicate a path beginning with a virtual directory. If a file named "header.inc" resides in a virtual directory named /html, the following line would insert the contents of "header.inc":
使用virtual关键词在指定一条虚拟路径。如果一个名为“header.inc”的文件保存在名为“/html”的虚拟文件夹下,那么使用下面的代码将插入“header.inc”的内容:
<!-- #include virtual ="/html/header.inc" -->
Use the file keyword to indicate a relative path. A relative path begins with the directory that contains the including file. If you have a file in the html directory, and the file "header.inc" resides in htmlheaders, the following line would insert "header.inc" in your file:
使用file关键词指出一条相对路径。相对路径始于当前文件夹,它包含了其中所有的文件。如果你在HTML文件夹中有一个文件,而“header.inc”文件又在“htmlheaders“路径下,那么,插入“header.inc”文件的方法如下:
<!-- #include file ="headersheader.inc" -->
Use the file keyword with the syntax (..) to include a file from a higher-level directory.
提示:使用file关键词时,如果使用“<..>”,则文件的路径要从最高级目录算起。
The Global.asa file is an optional file that can contain declarations of objects, variables, and methods that can be accessed by every page in an ASP application.
Global.asa文件是一个可选文件,它包括了对对象、变量的声明以及对每个页面应用程序访问方法的声明。
Note: The Global.asa file must be stored in the root directory of the ASP application, and each application can only have one Global.asa file.
注意:Global.asa文件必须被存储在ASP程序文件的根目录中,且每个应用程序文件只能拥有一个Global.asa文件。
The Global.asa file can contain only the following:
Global.asa文件只能包含以下内容:
Application and Session Events
Application事件和Session事件
In Global.asa you can tell the application and session objects what to do when the application/session starts and what to do when the application/session ends. The code for this is placed in event handlers. Note: We do not use <% and %>, to insert scripts in the Global.asa file, we have to put the subroutines inside the HTML <script> tag:
在Global.asa文件当中,你可以在它们开始或结束的时候区别Application和Session这两个对象,这些代码被放置在了事件处理器当中。注意:我们不使用“<%”和“%>”向Global.asa文件中插入脚本,我们需要把子程序放置到HTML<script>标签中。
<script language="vbscript" runat="server">
sub Application_OnStart
' some code
end sub
sub Application_OnEnd
' some code
end sub
sub Session_OnStart
' some code
end sub
sub Session_OnEnd
' some code
end sub
</script>
<object> Declarations
<object>声明
It is also possible to create objects with session or application scope in Global.asa by using the <object> tag. Note: The <object> tag should be outside the <script> tag!
我们也可以通过使用Global.asa中的<object>标签建立session和application对象。注意:<object>标签必须写在<script>标签之外
Syntax:
语法:
<object runat="server" scope="scope" id="id"
{progid="progID"|classid="classID"}>
.......
</object>
TypeLibrary Declarations
Typelibrary声明
A TypeLibrary is a container for the contents of a DLL file corresponding to a COM object. By including a call to the TypeLibrary in the Global.asa file, the constants of the COM object can be accessed, and errors can be better reported by the ASP code. If your Web application relies on COM objects that have declared data types in type libraries, you can declare the type libraries in Global.asa.
TypeLibrary声明涵盖了所有与COM对象相关的DLL文件的内容。通过呼叫Global.asa文件中的TypeLibrary,可以访问COM对象常量,所有的错误可以通过ASP代码很好的被显示出来。如果你的网络应用程序依赖一些已经在type library中声明了数据类型的COM对象,你也可以在Global.asa文件中声明type libraries。
Syntax:
语法:
<!--METADATA TYPE="TypeLib"
file="filename"
uuid="typelibraryuuid"
version="versionnumber"
lcid="localeid"
-->
The Session object is used to store information about, or change settings for a user session. Variables stored in the Session object hold information about one single user, and are available to all pages in one application.
Session对象是为用来存储使用者session信息或者改变使用者session设置的属性的。存储在Session对象中的变量包含了单个用户的所有信息,并且应用程序中的所有页面都是有效的。

A group of ASP files that work together to perform some purpose is called an application. The Application object in ASP is used to tie these files together. All users share one Application object. The Application object should hold information that will be used by many pages in the application (like database connection information).
一组为了实现某些目的和功能而在一起协同工作的ASP文件称为一个Application(应用程序)。ASP中的Application对象是用来绑定所有这些ASP文件的。所有的用户可以共享一个Application对象。通过Application对象所保存的所有信息可以在任何页面中使用(比如数据库连接信息)。
