我做了这个功能:

function transliterate(word){

    var answer = "";

    A = new Array();
    A["Ё"]="YO";A["Й"]="I";A["Ц"]="TS";A["У"]="U";A["К"]="K";A["Е"]="E";A["Н"]="N";A["Г"]="G";A["Ш"]="SH";A["Щ"]="SCH";A["З"]="Z";A["Х"]="H";A["Ъ"]="'";
    A["ё"]="yo";A["й"]="i";A["ц"]="ts";A["у"]="u";A["к"]="k";A["е"]="e";A["н"]="n";A["г"]="g";A["ш"]="sh";A["щ"]="sch";A["з"]="z";A["х"]="h";A["ъ"]="'";
    A["Ф"]="F";A["Ы"]="I";A["В"]="V";A["А"]="A";A["П"]="P";A["Р"]="R";A["О"]="O";A["Л"]="L";A["Д"]="D";A["Ж"]="ZH";A["Э"]="E";
    A["ф"]="f";A["ы"]="i";A["в"]="v";A["а"]="a";A["п"]="p";A["р"]="r";A["о"]="o";A["л"]="l";A["д"]="d";A["ж"]="zh";A["э"]="e";
    A["Я"]="YA";A["Ч"]="CH";A["С"]="S";A["М"]="M";A["И"]="I";A["Т"]="T";A["Ь"]="'";A["Б"]="B";A["Ю"]="YU";
    A["я"]="ya";A["ч"]="ch";A["с"]="s";A["м"]="m";A["и"]="i";A["т"]="t";A["ь"]="'";A["б"]="b";A["ю"]="yu";

for (i in word){

    if (A[word[i]] === 'undefined'){
        answer += word[i];
        }
    else {
        answer += A[word[i]];
        }

return answer;
}
}

现在它应该将西里尔文本音译为拉丁文，让拉丁文简单地通过。但它只能设法音译第一个，如果是拉丁语，它会给出未定义的答案。谁能给我一个想法，我做错了什么？

最佳答案

一些事情...

1. 使用 undefined 而不是 'undefined'
2. 不要将返回放在循环中
3. 使用 hasOwnProperty 过滤掉原型(prototype)上的函数和属性
4. 使用 [] 而不是 new Array()
5. 使用 {} 而不是 []
6. 使用小写变量而不是大写变量。大写保留给构造函数

这是代码

function transliterate(word){
    var answer = ""
      , a = {};

   a["Ё"]="YO";a["Й"]="I";a["Ц"]="TS";a["У"]="U";a["К"]="K";a["Е"]="E";a["Н"]="N";a["Г"]="G";a["Ш"]="SH";a["Щ"]="SCH";a["З"]="Z";a["Х"]="H";a["Ъ"]="'";
   a["ё"]="yo";a["й"]="i";a["ц"]="ts";a["у"]="u";a["к"]="k";a["е"]="e";a["н"]="n";a["г"]="g";a["ш"]="sh";a["щ"]="sch";a["з"]="z";a["х"]="h";a["ъ"]="'";
   a["Ф"]="F";a["Ы"]="I";a["В"]="V";a["А"]="А";a["П"]="P";a["Р"]="R";a["О"]="O";a["Л"]="L";a["Д"]="D";a["Ж"]="ZH";a["Э"]="E";
   a["ф"]="f";a["ы"]="i";a["в"]="v";a["а"]="a";a["п"]="p";a["р"]="r";a["о"]="o";a["л"]="l";a["д"]="d";a["ж"]="zh";a["э"]="e";
   a["Я"]="Ya";a["Ч"]="CH";a["С"]="S";a["М"]="M";a["И"]="I";a["Т"]="T";a["Ь"]="'";a["Б"]="B";a["Ю"]="YU";
   a["я"]="ya";a["ч"]="ch";a["с"]="s";a["м"]="m";a["и"]="i";a["т"]="t";a["ь"]="'";a["б"]="b";a["ю"]="yu";

   for (i in word){
     if (word.hasOwnProperty(i)) {
       if (a[word[i]] === undefined){
         answer += word[i];
       } else {
         answer += a[word[i]];
       }
     }
   }
   return answer;
}

比较实用的是这样的...

var a = {"Ё":"YO","Й":"I","Ц":"TS","У":"U","К":"K","Е":"E","Н":"N","Г":"G","Ш":"SH","Щ":"SCH","З":"Z","Х":"H","Ъ":"'","ё":"yo","й":"i","ц":"ts","у":"u","к":"k","е":"e","н":"n","г":"g","ш":"sh","щ":"sch","з":"z","х":"h","ъ":"'","Ф":"F","Ы":"I","В":"V","А":"А","П":"P","Р":"R","О":"O","Л":"L","Д":"D","Ж":"ZH","Э":"E","ф":"f","ы":"i","в":"v","а":"a","п":"p","р":"r","о":"o","л":"l","д":"d","ж":"zh","э":"e","Я":"Ya","Ч":"CH","С":"S","М":"M","И":"I","Т":"T","Ь":"'","Б":"B","Ю":"YU","я":"ya","ч":"ch","с":"s","м":"m","и":"i","т":"t","ь":"'","б":"b","ю":"yu"};

function transliterate(word){
  return word.split('').map(function (char) { 
    return a[char] || char; 
  }).join("");
}
