HttpClient在JavaScript上獲取編碼字符

Question

我想獲取html文件並解析此頁面。但HTML與編碼字符返回，我無法解決這個問題。

var client = Ti.Network.createHTTPClient({ 
     // function called when the response data is available 
     onload : function(e) { 
      var data = this; 
      callback(data); 
     }, 
     onerror : function(e) { 
      error(); 
     }, 
     timeout : 10000 // in milliseconds, 
    }); 


    client.open("GET",_link); 
    client.send(); 


Ka­dın­la­rın or­tak // A sample output ­ &amp etc. 

我該如何解決這個問題？

使用此功能，html_entity_decode取自此jsperf。爲了您的字符串：

html_entity_decode("Ka­dın­la­rın or­tak"); 
"Ka­dın­la­rın or­tak" 

下面是實際的功能，它會創建所有代碼的ehaustive地圖，然後替換它們：

function html_entity_decode(string, quote_style) { 
    var hash_map = {}, 
     symbol = '', 
     tmp_str = '', 
     entity = ''; 
    tmp_str = string.toString(); 

    if (false === (hash_map = get_html_translation_table('HTML_ENTITIES', quote_style))) { 
    return false; 
    } 

    // fix & problem 
    // http://phpjs.org/functions/get_html_translation_table:416#comment_97660 
    delete(hash_map['&']); 
    hash_map['&'] = '&'; 

    for (symbol in hash_map) { 
    entity = hash_map[symbol]; 
    tmp_str = tmp_str.split(entity).join(symbol); 
    } 
    tmp_str = tmp_str.split(''').join("'"); 

    return tmp_str; 
} 

function get_html_translation_table(table, quote_style) { 
    var entities = {}, 
     hash_map = {}, 
     decimal; 
    var constMappingTable = {}, 
     constMappingQuoteStyle = {}; 
    var useTable = {}, 
     useQuoteStyle = {}; 

    // Translate arguments 
    constMappingTable[0] = 'HTML_SPECIALCHARS'; 
    constMappingTable[1] = 'HTML_ENTITIES'; 
    constMappingQuoteStyle[0] = 'ENT_NOQUOTES'; 
    constMappingQuoteStyle[2] = 'ENT_COMPAT'; 
    constMappingQuoteStyle[3] = 'ENT_QUOTES'; 

    useTable = !isNaN(table) ? constMappingTable[table] : table ? table.toUpperCase() : 'HTML_SPECIALCHARS'; 
    useQuoteStyle = !isNaN(quote_style) ? constMappingQuoteStyle[quote_style] : quote_style ? quote_style.toUpperCase() : 'ENT_COMPAT'; 

    if (useTable !== 'HTML_SPECIALCHARS' && useTable !== 'HTML_ENTITIES') { 
    throw new Error("Table: " + useTable + ' not supported'); 
    // return false; 
    } 

    entities['38'] = '&';
