烈火建站学院（Bkjia.Com）PHP教程 PHP程序在COOKIE里写了点中文数据，而用Javascript读取时却读出来不能正确显示？相信很多朋友遇到过这种情况，前天搜索了一下，找到一种解决方法：PHP写COOKIE时以UTF-8编码写，而JS读出来的时候也解码一下就可以了，因为Javascript内部使用的是Unicode编码。
以下为引用的内容：
/**
*
* URL encode / decode
*
**/
var Url = {
// public method for url encoding
encode : function (string) {
return escape(this._utf8_encode(string));
},
// public method for url decoding
decode : function (string) {
return this._utf8_decode(unescape(string));
},
// private method for UTF-8 encoding
_utf8_encode : function (string) {
string = string.replace(/\r\n/g,"\n");
var utftext = "";
for (var n = 0; n
var c = string.charCodeAt(n);
if (c utftext += String.fromCharCode(c);
}
else if((c > 127) && (c utftext += String.fromCharCode((c >> 6) | 192);
utftext += String.fromCharCode((c & 63) | 128);
}
else {
utftext += String.fromCharCode((c >> 12) | 224);
utftext += String.fromCharCode(((c >> 6) & 63) | 128);
utftext += String.fromCharCode((c & 63) | 128);
}
}
return utftext;
},
// private method for UTF-8 decoding
_utf8_decode : function (utftext) {
var string = "";
var i = 0;
var c = c1 = c2 = 0;
while ( i
c = utftext.charCodeAt(i);
if (c string += String.fromCharCode(c);
i++;
}
else if((c > 191) && (c c2 = utftext.charCodeAt(i+1);
string += String.fromCharCode(((c & 31) i += 2;
}
else {
c2 = utftext.charCodeAt(i+1);
c3 = utftext.charCodeAt(i+2);
string += String.fromCharCode(((c & 15) i += 3;
}
}
return string;
}
}
/**
* 这段是读取Cookie
*/
function GetCookie(sName)
{
var mycookie = document.cookie.split("; ");
for (var i = 0; i {
var cookie1 = mycookie[i].split("=");
if (cookie1[0] == sName)
{
return Url.decode(cookie1[1]);
}
}
return null;
}
