JavaScript转义符
[code lang="vb"]
转义序列 字符
\b 退格
\f 走纸换页
\n 换行
\r 回车
\t 横向跳格 (Ctrl-I)
\' 单引号
\" 双引号
\\ 反斜杠[/code]

编程的时候要注意特殊字符的问题,很多运行时出现的问题都是因为特殊字符的出现而引起的。

注意,由于反斜杠本身用作转义符,因此不能直接在脚本中键入一个反斜杠。如果要产生一个反斜杠,必须一起键入两个反斜杠 (\\)。

编码转换(to Unicode)
(程序代码来源于网络)

Js版

[code lang="vb"]<script>
test = "你好abc"
str = ""
for( i=0; i<test.length; i++ )
{
temp = test.charCodeAt(i).toString(16);
str += "\\u"+ new Array(5-String(temp).length).join("0") +temp;
}
document.write (str)
</script>[/code]

vbs版

[code lang="vb"]Function Unicode(str1)
Dim str,temp
str = ""
For i=1 to len(str1)
temp = Hex(AscW(Mid(str1,i,1)))
If len(temp) < 5 Then temp = right("0000" & temp, 4)
str = str & "\u" & temp
Next
Unicode = str
End Function

Function htmlentities(str)
For i = 1 to Len(str)
char = mid(str, i, 1)
If Ascw(char) > 128 then
htmlentities = htmlentities & "&#" & Ascw(char) & ";"
Else
htmlentities = htmlentities & char
End if
Next
End Function
coldfusion版

function nochaoscode(str)
{
var new_str = “”;
for(i=1; i lte len(str);i=i+1){
if(asc(mid(str,i,1)) lt 128){
new_str = new_str & mid(str,i,1);
}else{
new_str = new_str & “&##” & asc(mid(str,i,1));
}
}
return new_str;
}[/code]
附:

在php中我们可以用mbstring的mb_convert_encoding函数实现这个正向及反向的转化。 如:

[code lang="php"]mb_convert_encoding ("你好", "HTML-ENTITIES", "gb2312"); //输出:&#20320;&#22909;

mb_convert_encoding ("&#20320;&#22909;", "gb2312", "HTML-ENTITIES"); //输出:你好[/code]

如果需要对整个页面转化,则只需要在php文件的头部加上这三行代码:

[code lang="vb"]mb_internal_encoding("gb2312"); // 这里的gb2312是你网站原来的编码

mb_http_output("HTML-ENTITIES");

ob_start('mb_output_handler');[/code]
[code lang="vb"][/code][/code]
