　　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;
}
