[Web Development]要不要打开新窗口 与 TARGET属性

转载自: http://diveintoaccessibility.org/day_16_not_opening_new_windows.html

Day 16: Not opening new windows The one thing every web user understands is the "Back" button. It's an integral part of browsing the web. Follow a link, go back. Explore a search engine result, go back. Even my father can do this, and he's still excited when he can double-click the "Internet" icon successfully on the first try. In all dominant browsers, using the tag to force a link to open in a new window breaks the Back button. The new window does not retain the browser history of the previous window, so the "Back" button is disabled. This is incredibly confusing, even for me, and I've been using the web for 10 years. In 2002, it's amazing that people still do this. Don't do this. Don't force links to open in new windows. Please note that this tip is about you as a web designer, not you as a web user. If you want to open new windows while you browse, go right ahead. In Internet Explorer for Windows, hold down the Shift key while you click a link to open the link in a new window. In Netscape 6 and Mozilla, hold down Control. In Internet Explorer for Mac, hold down Command. (Some browsers such as Opera support advanced combinatio



[Web Development]通过代理服务器 使用 XMLHTTP 

转载自: http://blog.mvpcn.net/possible/archive/2004/11/07/5149.aspx

使用代理的情况下在服务器端使用XMLHTTP 最近同事在asp的服务器端程序里用xmlhttp来post数据的时候遇到了问题,始终不能成功。

(http://xxxx.xx.xx/xxx/xx.asp是internet上的,可以访问的)

    开始觉得很奇怪,因为以前在学校里时经常在服务器端程序里用xmlhttp都没有任何问题。试了一下把服务器端程序改为客户端的javascript程序在ie运行或者直接写成vbs文件运行,都可以成功地post。而后又发现如果把目标url改为localhost或公司局域网内的机器的都可以成功地post。
    看来是网络环境的问题,可是为什么客户端的javascript程序又能正常呢?
    最后想到了是使用了代理的问题(这里要多谢inlem的提醒),因为公司是通过代理上的internet,而我们的ie里都是正确的设置了代理的,所以客户端的javascript程序可以成功地post。而WinHTTP则没有设置,所以server to server始终不能正常连接。
    最后用proxycfg.exe来设置WinHTTP。proxycfg是ms提供的工具,win XP默认在System32下就有proxycfg.exe,而win2000需要到http://msdn.microsoft.com/msdn-files/027/001/468/Proxycfg.exe下载。关于proxycfg配制WinHTTP:
   (1)、在server-to-server时,不使用proxy servers,则在cmd里运行proxycfg -d
   (2)、在server-to-server时,使用proxy servers,则在cmd里运行proxycfg -p myProxyServer:80 ""
      还有一个简单的配制方法,就是先在IE里



[Web Development]ECMAScript介绍

转载自: http://en.wikipedia.org/wiki/ECMAScript

ECMAScript, in simple terms, is the greatest common subset of JavaScript and JScript. It is a scripting programming language created to capture the common core language elements of both languages. The Language Specification is published by the ECMA International. Development of the standard began in 1996. It has now been accepted as ISO standard 16262. The standard is now the fourth edition, known as E4X (ECMAScript for XML), which standardizes the syntax and semantics of a general-purpose, cross-platform, vendor-neutral set of progr
