Several programming languages implement a sprintf function, to output a formatted string. It originated from the C programming language, printf function. Its a string manipulation function.
This is limited sprintf Javascript implementation. Function returns a string formatted by the usual printf conventions. See below for more details. You must specify the string and how to format the variables in it. Possible format values:
%% – Returns a percent sign
%b – Binary number
%c – The character according to the ASCII value
%d – Signed decimal number
%f – Floating-point number
%o – Octal number
%s – String
%x – Hexadecimal number (lowercase letters)
%X – Hexadecimal number (uppercase letters)
Additional format values. These are placed between the % and the letter (example %.2f):
+ (Forces both + and – in front of numbers. By default, only negative numbers are marked)
– (Left-justifies the variable value)
0 zero will be used for padding the results to the right string size
[0-9] (Specifies the minimum width held of to the variable value)
.[0-9] (Specifies the number of decimal digits or maximum string length)
If you plan using UTF-8 encoding in your project don’t forget to set the page encoding to UTF-8 (Content-Type meta tag), and use Javascript UTF-8 utility found on this website.

前台页面为 子页面为一个按钮：
<form id="form1" runat="server">
<div>
<asp:Button runat="server" ID="Bt_Add" Text="添加" Width="80px" Height="20px" OnClick="Bt_Add_Click" />

Flex 与 JavaScript 交互，主要依靠Flex的ExternalInterface，其提供了addCallBack和call方法.
下面的例子将演示Flex调用javascript，和javascript调用Flex。
js 代码

function hello(param) {
......
1. oncontextmenu="window.event.returnValue=false" 将彻底屏蔽鼠标右键
<table border oncontextmenu=return(false)><td>no</table> 可用于Table
2. <body onselectstart="return false"> 取消选取、防止复制
3. onpaste="return false" 不准粘贴
4. oncopy="return false;" oncut="return f ......
