JavaScript转义符

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

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

<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>

vbs版

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;
}

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:

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

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

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:

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]
