    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');




    =================================================

    单引号,双引号,javascript,HTML,转义字符
    2009-08-03 10:27

     

    在一个网页中的按钮，写onclick事件的处理代码，不小心写成如下：
    <input value="Test" type="button" onclick="alert(""OK"");" />
    IE提示出错后，再漫不经心地改为：
    <input value="Test" type="button" onclick="alert(\"OK\");" />
    结果还是出错。
    这时，我就想不通了，虽然我知道最直接的解决方法是写成这样：
    <input value="" type="button" onclick="alert('OK');" />
    但为什么javascript中的转义字符\没有效果了呢？

    后来找到一段正常的代码：
    <input value="Test" type="button" onclick="alert(&quot;OK&quot;);" />
    这时才理解，原来这时，还是归于HTML的管辖范围，所以转义字符应该使用HTML的，而不是javascript的。两个双引号的做法是vbScript 的，\"这种做法则是javascript的，而HTML的，则是用&quot;，此外还可以使用："、&#x27。

    下面列出各种表达方法：
    <html>
    <body>
    <input value="外双引号内双引号-错误" type="button" onclick="alert("OK");" /><br />
    <input value="外单引号内单引号-错误" type="button" onclick='alert('OK');' /><br />
    <input value="两个双引号-错误" type="button" onclick="alert(""OK"");" /><br />
    <input value="两个单引号-错误" type="button" onclick="alert(''OK'');" /><br />
    <input value="\+双引号-错误" type="button" onclick="alert(\"OK\");" /><br />
    <input value="\+单引号-错误" type="button" onclick="alert(\'OK\');" /><br />
    <input value="外双引号内单引号-OK" type="button" onclick="alert('OK');" /><br />
    <input value="外单引号内双引号-OK" type="button" onclick='alert("OK");' /><br />
    <input value="外部不使用引号-OK" type="button" onclick=alert('OK');alert("OK"); /><br />
    <input value="HTML转义字符"(& # 3 4 ;)-OK" type="button" onclick="alert("OK");" /><br />
    <input value="HTML转义字符'(& # 3 9 ;)-OK" type="button" onclick="alert('OK');" /><br />
    <input value="HTML转义字符"(& # x 2 2 ;)-OK" type="button" onclick="alert('OK');" /><br />
    <input value="HTML转义字符'(& # x 2 7 ;)-OK" type="button" onclick="alert('OK');" /><br />
    <input value="HTML转义字符&quot;(& q u o t ;)-OK" type="button" onclick="alert(&quot;OK&quot;);" /><br />
    <input value="HTML转义字符&apos;(& a p o s ;)-IE错误" type="button" onclick="alert(&apos;OK&apos;);" /><br />

    <input value="其它\\-错误" type="button" onclick="alert(\\"OK\\");" /><br />
    <input value="其它\& # 3 4 ;-错误" type="button" onclick="alert(\"OK\");" /><br />
    </body>
    </html>
