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, "+");
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('%', '%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
