Html编码在JavaScript和解码在C＃

Question

我想在我的js文件中为中文字符做html编码，它返回一些无效字符。

My text : 奥妙 全自动洁彩深层洁净洗衣液3kg 
My html encode: kgoxAyM2tn 
My htmldecoded term: �1#6 

我的代码：

// TODO get the ID of the select so that we can add this as a new dependency 
        var searchKeyword = $('#txtBox' + id).val(); 
        var pId = $('#SearchTerm_ > option:selected').attr("value"); 
        var encodedSearchTerm = Encode(searchKeyword); 
        if (!(searchKeyword)) { 
         return false; 
        } else if (pId <= 0) { 
         return false; 
        } 

    function Encode(urlFragment) { 
    urlFragment = $.base64.encode(urlFragment); 
    return urlFragment; 
    };

张贴作为一个答案：

这jfiddle做编码将让你在你需要：

var Base64 = { 


_keyStr: "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz/=", 


encode: function(input) { 
    var output = ""; 
    var chr1, chr2, chr3, enc1, enc2, enc3, enc4; 
    var i = 0; 

    input = Base64._utf8_encode(input); 

    while (i < input.length) { 

     chr1 = input.charCodeAt(i++); 
     chr2 = input.charCodeAt(i++); 
     chr3 = input.charCodeAt(i++); 

     enc1 = chr1 >> 2; 
     enc2 = ((chr1 & 3) << 4) | (chr2 >> 4); 
     enc3 = ((chr2 & 15) << 2) | (chr3 >> 6); 
     enc4 = chr3 & 63; 

     if (isNaN(chr2)) { 
      enc3 = enc4 = 64; 
     } else if (isNaN(chr3)) { 
      enc4 = 64; 
     } 

     output = output + this._keyStr.charAt(enc1) + this._keyStr.charAt(enc2) + this._keyStr.charAt(enc3) + this._keyStr.charAt(enc4); 

    } 

    return output; 
}, 


decode: function(input) { 
    var output = ""; 
    var chr1, chr2, chr3; 
    var enc1, enc2, enc3, enc4; 
    var i = 0; 

    input = input.replace(/[^A-Za-z0-9\+\/\=]/g, ""); 

    while (i < input.length) { 

     enc1 = this._keyStr.indexOf(input.charAt(i++)); 
     enc2 = this._keyStr.indexOf(input.charAt(i++)); 
     enc3 = this._keyStr.indexOf(input.charAt(i++)); 
     enc4 = this._keyStr.indexOf(input.charAt(i++)); 

     chr1 = (enc1 << 2) | (enc2 >> 4); 
     chr2 = ((enc2 & 15) << 4) | (enc3 >> 2); 
     chr3 = ((enc3 & 3) << 6) | enc4; 

     output = output + String.fromCharCode(chr1); 

     if (enc3 != 64) { 
      output = output + String.fromCharCode(chr2); 
     } 
     if (enc4 != 64) { 
      output = output + String.fromCharCode(chr3); 
     } 

    } 

    output = Base64._utf8_decode(output); 

    return output; 

}, 

_utf8_encode: function(string) { 
    string = string.replace(/\r\n/g, "\n"); 
    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; 
}, 

_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; 
} 

} 



var encode = document.getElementById('encode'), 
decode = document.getElementById('decode'), 
output = document.getElementById('output'), 
input = document.getElementById('input'); 


encode.onclick = function() { 
output.innerHTML = Base64.encode(input.value); 
} 

decode.onclick = function() { 
var $str = output.innerHTML; 
output.innerHTML = Base64.decode($str); 
}  

JavaScript可用于使用MIME base64对数据进行编码/解码，并与UTF-8编码完全兼容。
