JSP環(huán)境下如何解決Ajax亂碼問題
導(dǎo)語:為了方便大家的亂碼問題解決,下面是小編給大家提供的JSP環(huán)境下如何解決Ajax亂碼問題,大家可以參考閱讀,更多詳情請關(guān)注應(yīng)屆畢業(yè)生考試網(wǎng)。
AJAX傳遞中文字符串時必須把中文字符串編碼成unicode,一般會用到JS的自帶函數(shù)escape().不過找到了更好的函數(shù)來確決中文字符轉(zhuǎn)換成unicode編碼的函數(shù)
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;
}
當(dāng)然服務(wù)器端要對編碼過的字符串進行第二次轉(zhuǎn)碼.把字符串轉(zhuǎn)換成UTF-8編碼.
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));
}
}
