Transliterating Russian to English in JavaScript

Transliterating a text in Russian to English in JavaScript. Three ways:

  1. Characters are stored in a JSON object
  2. Characters are stored in an array
  3. Replacing characters in a text one by one with replace()

1. Characters in JSON object

Transliterating: "Транслитерация с русского на английский с помощью JavaScript"

HTML code:


<div class="example"></div>

JavaScript code:


<script>
var text = 'Транслитерация с русского на английский с помощью JavaScript #1';
var result = '';
var characters = {'а':'a', 'б':'b', 'в':'v', 'г':'g', 'д':'d', 'е':'e', 'ё':'yo', 'ж':'zh', 'з':'z', 'и':'i', 'й':'y', 'к':'k', 'л':'l', 'м':'m', 'н':'n', 'о':'o', 'п':'p', 'р':'r', 'с':'s', 'т':'t', 'у':'u', 'ф':'f', 'х':'h', 'ц':'c', 'ч':'ch', 'ш':'sh', 'щ':'shch', 'ь':'', 'ы':'y', 'ъ':'', 'э':'e', 'ю':'yu', 'я':'ya', 'А':'A', 'Б':'B', 'В':'V', 'Г':'G', 'Д':'D', 'Е':'E', 'Ё':'Yo', 'Ж':'Zh', 'З':'Z', 'И':'I', 'Й':'Y', 'К':'K', 'Л':'L', 'М':'M', 'Н':'N', 'О':'O', 'П':'P', 'Р':'R', 'С':'S', 'Т':'T', 'У':'U', 'Ф':'F', 'Х':'H', 'Ц':'C', 'Ч':'Ch', 'Ш':'Sh', 'Щ':'Shch', 'Ь':'', 'Ы':'Y', 'Ъ':'', 'Э':'E', 'Ю':'Yu', 'Я':'Ya'};

for ( var i = 0; i < text.length; i++ ) {
	if ( characters[ text[i] ] == undefined ){
		result += text[i];
	} else {
		result += characters[ text[i] ];
	}
};

// Printing the resulting text
document.querySelector('.example').textContent = result;
</script>

2. Characters in array

Transliterating: "Транслитерация с русского на английский с помощью JavaScript #2"

HTML code:


<div class="example2"></div>

JavaScript code:


<script>
var text = 'Транслитерация с русского на английский с помощью JavaScript #2';
var result2 = '';
var chars = [];

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

for ( var i = 0; i < text.length; ++i ) {
	if ( chars[ text[i] ] == undefined ){
		result2 += text[i];
	} else {
		result2 += chars[ text[i] ];
	}
}

// Printing the resulting text
document.querySelector('.example2').textContent = result2;
</script>

3. Replacing characters one by one with replace()

Transliterating: "Транслитерация с русского на английский с помощью JavaScript #3"

HTML code:


<div class="example3"></div>

JavaScript code:


<script>
var text = 'Транслитерация с русского на английский с помощью JavaScript #3';

text = text.replace(/\u0410/g, 'А');
text = text.replace(/\u0411/g, 'B');

// Printing the resulting string
document.querySelector('.example3').textContent = text;
