Sostituzione di segni diacritici in Javascript

Question

Come posso sostituire i segni diacritici (ă, ş, ţ ecc.) Con la loro forma "normale" (a, s, t) in javascript?

Answer 1

Se si desidera eseguire interamente dal lato client, penso che la tua unica opzione sia con una sorta di tabella di ricerca. Ecco un punto di partenza, scritto da un tizio chiamato Olavi Ivask sul suo blog ...

function replaceDiacritics(s) 
{ 
    var s; 

    var diacritics =[ 
     /[\300-\306]/g, /[\340-\346]/g, // A, a 
     /[\310-\313]/g, /[\350-\353]/g, // E, e 
     /[\314-\317]/g, /[\354-\357]/g, // I, i 
     /[\322-\330]/g, /[\362-\370]/g, // O, o 
     /[\331-\334]/g, /[\371-\374]/g, // U, u 
     /[\321]/g, /[\361]/g, // N, n 
     /[\307]/g, /[\347]/g, // C, c 
    ]; 

    var chars = ['A','a','E','e','I','i','O','o','U','u','N','n','C','c']; 

    for (var i = 0; i < diacritics.length; i++) 
    { 
     s = s.replace(diacritics[i],chars[i]); 
    } 

    document.write(s); 
} 

Si può vedere questo è semplicemente un insieme di espressioni regolari per noti caratteri diacritici, loro mappatura di nuovo su un personaggio "normale".

Answer 2

Si avrebbe bisogno di una mappa di conversione, qualcosa di simile:

function removeAccents(str) { 
    var convMap = { 
     "ă" : "a", 
     "ş" : "s", 
     "ţ" : "t" 
    } 
    for (var i in convMap) { 
     str = str.replace(new RegExp(i, "g"), convMap[i]); 
    } 
    return str; 
} 

O se si ha accesso al iconv sulla propria macchina, si potrebbe forse usare un po 'di chiamate AJAX per rimuovere gli accenti con il parametro Translit // di iconv .

Answer 3

Una semplice modifica alla sceneggiatura di Paul. Estendere l'String-oggetto

String.prototype.removeDiacritics = function() { 
    var diacritics = [ 
     [/[\300-\306]/g, 'A'], 
     [/[\340-\346]/g, 'a'], 
     [/[\310-\313]/g, 'E'], 
     [/[\350-\353]/g, 'e'], 
     [/[\314-\317]/g, 'I'], 
     [/[\354-\357]/g, 'i'], 
     [/[\322-\330]/g, 'O'], 
     [/[\362-\370]/g, 'o'], 
     [/[\331-\334]/g, 'U'], 
     [/[\371-\374]/g, 'u'], 
     [/[\321]/g, 'N'], 
     [/[\361]/g, 'n'], 
     [/[\307]/g, 'C'], 
     [/[\347]/g, 'c'], 
    ]; 
    var s = this; 
    for (var i = 0; i < diacritics.length; i++) { 
     s = s.replace(diacritics[i][0], diacritics[i][1]); 
    } 
    return s; 
} 

Ora si può fare:

var wrongString = "hëllô"; 
alert(wrongString.removeDiacritics()); // alerts "hello"

Answer 5

ho portato il filtro Folding Apache Lucene ASCII a JavaScript. È possibile sostituire molti caratteri Unicode (compresi i segni diacritici) in moduli di base ASCII.

È possibile trovare la porta su https://github.com/mplatt/fold-to-ascii-js

Dopo l'integrazione della biblioteca si potrebbe piegare le stringhe del genere:

foldToASCII("ăşţ"); 

che si tradurrebbe in ast.

Answer 6

consideri seguente sintassi dove ogni simbolo dal loro valore sarà sostituito con esso è simbolo di una chiave (-sensitive)

var diacritics = { 
    a: 'ÀÁÂÃÄÅàáâãäåĀāąĄ', 
    c: 'ÇçćĆčČ', 
    d: 'đĐďĎ', 
    e: 'ÈÉÊËèéêëěĚĒēęĘ', 
    i: 'ÌÍÎÏìíîïĪī', 
    l: 'łŁ', 
    n: 'ÑñňŇńŃ', 
    o: 'ÒÓÔÕÕÖØòóôõöøŌō', 
    r: 'řŘ', 
    s: 'ŠšśŚ', 
    t: 'ťŤ', 
    u: 'ÙÚÛÜùúûüůŮŪū', 
    y: 'ŸÿýÝ', 
    z: 'ŽžżŻźŹ' 
} 

function replaceDiacritics(text) {

Questo metodo è una refactor della prima risposta.

function replaceDiacritics(str){ 

    var diacritics = [ 
    {char: 'A', base: /[\300-\306]/g}, 
    {char: 'a', base: /[\340-\346]/g}, 
    {char: 'E', base: /[\310-\313]/g}, 
    {char: 'e', base: /[\350-\353]/g}, 
    {char: 'I', base: /[\314-\317]/g}, 
    {char: 'i', base: /[\354-\357]/g}, 
    {char: 'O', base: /[\322-\330]/g}, 
    {char: 'o', base: /[\362-\370]/g}, 
    {char: 'U', base: /[\331-\334]/g}, 
    {char: 'u', base: /[\371-\374]/g}, 
    {char: 'N', base: /[\321]/g}, 
    {char: 'n', base: /[\361]/g}, 
    {char: 'C', base: /[\307]/g}, 
    {char: 'c', base: /[\347]/g} 
    ] 

    diacritics.forEach(function(letter){ 
    str = str.replace(letter.base, letter.char); 
    }); 

    return str; 
};

nei browser moderni e Node.js è possibile utilizzare unicode normalization a decomporsi quei caratteri seguiti da una regex filtraggio.

str.normalize('NFD').replace(/[^\w]/g, '')

Se si voleva consentire personaggi come spazi bianchi, trattini, ecc Si dovrebbe estendere l'espressione regolare per consentire loro.

str.normalize('NFD').replace(/[^\w\s.-_\/]/g, '')

var str = 'áàâäãéèëêíìïîóòöôõúùüûñçăşţ'; 
 
var asciiStr = str.normalize('NFD').replace(/[^\w]/g, ''); 
 
console.info(str, asciiStr);
