jsp环境下ajax乱码问题的解决
时间：2011-05-02 来源：guoyiqi
AJAX传递中文字符串时必须把中文字符串编码成unicode,一般会用到JS的自带函数escape().不过找到了更好的函数来确决中文字符转换成unicode编码的函数
- function uniencode(text)
- {
- text = escape(text.toString()).replace(/\+/g, "%2B");
- var matches = text.match(/(%([0-9A-F]{2}))/gi);
- if (matches)
- {
- for (var matchid = 0; matchid < matches.length; matchid++)
- {
- var code = matches[matchid].substring(1,3);
- if (parseInt(code, 16) >= 128)
- {
- text = text.replace(matches[matchid], '%u00' + code);
- }
- }
- }
- text = text.replace('%25', '%u0025');
- return text;
- }
当然服务器端要对编码过的字符串进行第二次转码.把字符串转换成UTF-8编码.
- function convert_int_to_utf8($intval)
- {
- $intvalintval = intval($intval);
- switch ($intval)
- {
- // 1 byte, 7 bits
- case 0:
- return chr(0);
- case ($intval & 0x7F):
- return chr($intval);
- // 2 bytes, 11 bits
- case ($intval & 0x7FF):
- return chr(0xC0 | (($intval >> 6) & 0x1F)) .
- chr(0x80 | ($intval & 0x3F));
- // 3 bytes, 16 bits
- case ($intval & 0xFFFF):
- return chr(0xE0 | (($intval >> 12) & 0x0F)) .
- chr(0x80 | (($intval >> 6) & 0x3F)) .
- chr (0x80 | ($intval & 0x3F));
- // 4 bytes, 21 bits
- case ($intval & 0x1FFFFF):
- return chr(0xF0 | ($intval >> 18)) .
- chr(0x80 | (($intval >> 12) & 0x3F)) .
- chr(0x80 | (($intval >> 6) & 0x3F)) .
- chr(0x80 | ($intval & 0x3F));
- }
- }
这样中文字符串就可以转换成UTF-8编码.这种方法适合各种服务器环境
