建站学院（LieHuo.Net）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(//g,"");
var utftext = ""; for (var n = 0; n < string.length; n++) { var c = string.charCodeAt(n); if (c < 128) {
utftext += String.fromCharCode(c);
}
else if((c > 127) && (c < 2048)) {
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 < utftext.length ) { c = utftext.charCodeAt(i); if (c < 128) {
string += String.fromCharCode(c);
i++;
}
else if((c > 191) && (c < 224)) {
c2 = utftext.charCodeAt(i+1);
string += String.fromCharCode(((c & 31) << 6) | (c2 & 63));
i += 2;
}
else {
c2 = utftext.charCodeAt(i+1);
c3 = utftext.charCodeAt(i+2);
string += String.fromCharCode(((c & 15) << 12) | ((c2 & 63) << 6) | (c3 & 63));
i += 3;
} } return string;
} } /**
* 这段是读取Cookie
*/
function GetCookie(sName)
{
var mycookie = document.cookie.split("; ");
for (var i = 0; i < mycookie.length; i++)
{
var cookie1 = mycookie[i].split("=");
if (cookie1[0] == sName)
{
return Url.decode(cookie1[1]);
}
}
return null;
