Supprimer les accents/signes diacritiques dans une chaîne en JavaScript

Question

Comment puis-je supprimer les caractères accentués d'une chaîne? En particulier dans IE6, j'avais quelque chose comme ceci:

accentsTidy = function(s){
    var r=s.toLowerCase();
    r = r.replace(new RegExp(/\s/g),"");
    r = r.replace(new RegExp(/[àáâãäå]/g),"a");
    r = r.replace(new RegExp(/æ/g),"ae");
    r = r.replace(new RegExp(/ç/g),"c");
    r = r.replace(new RegExp(/[èéêë]/g),"e");
    r = r.replace(new RegExp(/[ìíîï]/g),"i");
    r = r.replace(new RegExp(/ñ/g),"n");                
    r = r.replace(new RegExp(/[òóôõö]/g),"o");
    r = r.replace(new RegExp(/œ/g),"oe");
    r = r.replace(new RegExp(/[ùúûü]/g),"u");
    r = r.replace(new RegExp(/[ýÿ]/g),"y");
    r = r.replace(new RegExp(/\W/g),"");
    return r;
};

mais IE6 me perturbe, semble ne pas aimer mon expression habituelle.

Answer 1

Avec ES2015/ES6 String.Prototype.Normalize () ,

const str = "Crème Brulée"
str.normalize('NFD').replace(/[\u0300-\u036f]/g, "")
> 'Creme Brulee'

Deux choses se passent ici:

1. normalize()ing to NFD La forme normale Unicode décompose les graphèmes combinés en une combinaison de graphèmes simples. Le è de Crème finit par être exprimé par e + ̀.
2. En utilisant une expression rationnelle classe de caractères pour correspondre à la plage U + 0300 → U + 036F, il est maintenant trivial de supprimer globally de la diacritique, que le standard Unicode regroupe commodément sous la forme Combinaison de marques diacritiques .

Voir le commentaire pour les tests de performance.

Alternativement, si vous voulez juste trier

Intl.Collator a un support suffisant ~ 85% actuellement , un polyfill est également disponible ici mais je ne l'ai pas testé.

const c = new Intl.Collator();
['creme brulee', 'crème brulée', 'crame brulai', 'crome brouillé',
'creme brulay', 'creme brulfé', 'creme bruléa'].sort(c.compare)
[ 'crame brulai','creme brulay','creme bruléa','creme brulee',
'crème brulée','creme brulfé','crome brouillé' ]


['creme brulee', 'crème brulée', 'crame brulai', 'crome brouillé'].sort((a,b) => a>b)
["crame brulai", "creme brulee", "crome brouillé", "crème brulée"]

Answer 2

J'ai légèrement modifié la version de khel pour une raison: chaque expression rationnelle/remplacement coûtera O(n) opérations, où n est le nombre de caractères du texte cible. Mais, regexp n'est pas exactement ce dont nous avons besoin. Alors:

Answer 5

Le format de la nouvelle RegExp est

RegExp(something, 'modifiers');

Donc vous voudriez

accentsTidy = function(s){
                        var r=s.toLowerCase();
                        r = r.replace(new RegExp("\\s", 'g'),"");
                        r = r.replace(new RegExp("[àáâãäå]", 'g'),"a");
                        r = r.replace(new RegExp("æ", 'g'),"ae");
                        r = r.replace(new RegExp("ç", 'g'),"c");
                        r = r.replace(new RegExp("[èéêë]", 'g'),"e");

Answer 6

Code abrégé basé sur l'excellente solution de Ian Elliott:

accentsTidy = function(s){
    var r = s.toLowerCase();
    non_asciis = {'a': '[àáâãäå]', 'ae': 'æ', 'c': 'ç', 'e': '[èéêë]', 'i': '[ìíîï]', 'n': 'ñ', 'o': '[òóôõö]', 'oe': 'œ', 'u': '[ùúûűü]', 'y': '[ýÿ]'};
    for (i in non_asciis) { r = r.replace(new RegExp(non_asciis[i], 'g'), i); }
    return r;
};

Edit: code non fonctionnel corrigé

Answer 7

Vous pouvez utiliser la méthode _.deburr de la bibliothèque Lodash.

Il est disponible en tant que package NPM autonome lodash.deburr , ou en tant que partie du package lodash .

let myStringWithAccent = 'Mon café est plein de caféïne';
let myStringWithoutAccent = deburr(myStringWithAccent);

Le résultat sera: "Mon cafe est plein de cafeine"

Answer 8

Une solution qui semble bien plus rapide selon le test donné: http://jsperf.com/diacritics/9

function removeDiacritics(str) {
   return str.replace(/[^A-Za-z0-9\s]+/g, function(a){
      return diacriticsMap[a] || a; 
   });
}
removeDiacritics(teste);

Exemple de travail: http://jsbin.com/sovorute/1/edit

Reasoning: Une des raisons pour laquelle cela est beaucoup plus rapide est que nous ne parcourons que les caractères spéciaux, choisis par le modèle de regex nié. Le plus rapide des tests (String Iteration sans dans) itère 1001 sur le texte donné, ce qui signifie chaque caractère. Celui-ci n'itère que 35 fois et sort le résultat même résultat. Gardez à l'esprit que cela ne fera que remplacer ce qui est indiqué sur la carte.

Article classique sur le sujet: http://alistapart.com/article/accent-folding-for-auto-complete

Credit: http://semplicewebsites.com/removing-accents-javascript fournit également une belle carte de caractères.

Answer 9

NPM propose un package pour cela: latinize

C'est un très bon paquet pour résoudre ce problème.

Answer 10

J'ai ajouté le code de billyhttp://jsfiddle.net/billybraga/UHmnf/ (à partir de post ) dans ceci: http: // jsfiddle. filet/infralabs/dJX58/

J'ai corrigé la transcription des caractères ſ et ß et ajouté des couvertures de ceux-ci: Þþ, Ðð, Ŋŋ, IJij, Œœ.

Answer 11

Un moyen plus simple de remplacer les signes diacritiques.

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;
};

Voici une solution très simple, sans trop de code, utilisant une très simple carte de signes diacritiques incluant tout ou partie de cette carte en équivalents ascii contenant plus d’un caractère, c’est-à-dire Æ => AE, => ffi, etc ... tests fonctionnels très basiques

Answer 14

Il y en a beaucoup, mais je pense que celui-ci est simple et assez bon:

 function remove_accents(strAccents) {
    var strAccents = strAccents.split('');
    var strAccentsOut = new Array();
    var strAccentsLen = strAccents.length;
    var accents =    "ÀÁÂÃÄÅàáâãäåÒÓÔÕÕÖØòóôõöøÈÉÊËèéêëðÇçÐÌÍÎÏìíîïÙÚÛÜùúûüÑñŠšŸÿýŽž";
    var accentsOut = "AAAAAAaaaaaaOOOOOOOooooooEEEEeeeeeCcDIIIIiiiiUUUUuuuuNnSsYyyZz";
    for (var y = 0; y < strAccentsLen; y++) {
        if (accents.indexOf(strAccents[y]) != -1) {
            strAccentsOut[y] = accentsOut.substr(accents.indexOf(strAccents[y]), 1);
        } else
            strAccentsOut[y] = strAccents[y];
    }
    strAccentsOut = strAccentsOut.join('');

    return strAccentsOut;
}

Si vous souhaitez également supprimer des caractères spéciaux et transformer des espaces et des tirets dans les traits de soulignement, procédez comme suit:

string = remove_accents(string);
string = string.replace(/[^a-z0-9\s]/gi, '').replace(/[-\s]/g, '_');

Answer 15

J'ai fourni cette réponse pour une question similaire. Il est basé sur le remplacement rapide de tables pour les caractères sélectionnés (latin 1 + 2), un pour un (impossible de changer l'allemand ü en "ue"), mais fonctionne bien pour la "normalisation" de base en ASCII 7 bits.

TAB_00C0 = "AAAAAAACEEEEIIII" +
    "DNOOOOO*OUUUUYIs" +
    "aaaaaaaceeeeiiii" +
    "?nooooo/ouuuuy?y" +
    "AaAaAaCcCcCcCcDd" +
    "DdEeEeEeEeEeGgGg" +
    "GgGgHhHhIiIiIiIi" +
    "IiJjJjKkkLlLlLlL" +
    "lLlNnNnNnnNnOoOo" +
    "OoOoRrRrRrSsSsSs" +
    "SsTtTtTtUuUuUuUu" +
    "UuUuWwYyYZzZzZzF";

function stripDiacritics(source) {
    var result = source.split('');
    for (var i = 0; i < result.length; i++) {
        var c = source.charCodeAt(i);
        if (c >= 0x00c0 && c <= 0x017f) {
            result[i] = String.fromCharCode(TAB_00C0.charCodeAt(c - 0x00c0));
        } else if (c > 127) {
            result[i] = '?';
        }
    }
    return result.join('');
}

stripDiacritics("Šupa, čo? ľšťčžýæøåℌð")

Tous les autres caractères sont convertis en?, Le résultat est un code ASCII 7 bits. Pas de regex, pas de magie, simple travail sur tableau de caractères.

Answer 16

merci à tous
J'utilise cette version et explique pourquoi (parce que ces explications me manquent au début, j'essaie donc d'aider le prochain lecteur s'il est aussi ennuyeux que moi ...)

Remarque: je voulais une solution efficace, donc:

• une seule compilation regexp (si nécessaire)
• un seul balayage de chaîne pour chaque chaîne
• un moyen efficace de trouver les caractères traduits etc ...

Ma version est:

    };
    return function(s) {
        return(s.replace(translate_re, function(match){return translate[match];}) );
    }
})();

et je l'utilise de cette façon:

var without_accents = makeSortString("wïthêüÄTrèsBïgüeAk100t");
// I let you guess the result,
// no I was kidding you : I give you the result : witheuatresbigueak100t

Commentaires :

• L'instruction à l'intérieur est faite une fois (après, makeSortString! = Indéfini)
• function () {...} est stocké une fois dans makeSortString, ainsi les "gros" objets translate_re et translate sont stockés une fois
• Lorsque vous appelez makeSortString ('quelque chose'), il appelle directement la fonction inside qui appelle uniquement à la place (...): c'est efficace
• s.replace utilise regexp (la syntaxe spéciale de var translate_re = .... est en fait équivalente à var translate_re = new RegExp ("[¹ .... Z]", "g"); mais la compilation de l'expression rationnelle est fait une fois pour toutes et l'analyse de la chaîne s est effectuée une pour un appel de la fonction (pas pour chaque caractère comme il le serait dans une boucle)
• Pour chaque caractère trouvé, appelle à la place une fonction (correspondance) où la correspondance de paramètre contient le caractère trouvé et appelle le caractère traduit correspondant (translate [correspondance])
• Translate [match] est probablement efficace aussi, car l'objet de traduction javascript est probablement implémenté par javascript avec un hashtab ou quelque chose d'équivalent et permet au programme de trouver le caractère traduit presque directement et non par exemple via une boucle sur un tableau de tous les caractères le bon (ce qui serait terriblement inefficace).

Answer 17

le moyen testé le plus rapide pour supprimer les signes diacritiques de la chaîne qui couvre presque tous les caractères est ceci . trouvé plus haut performance parmi toutes les autres méthodes

Answer 18

Transmettez une fonction définie par l'utilisateur à la méthode Array.sort() et utilisez cette fonction définie par l'utilisateur String.localeCompare()

function myCompareFunction(a, b) {
  return a.localeCompare(b);
}

var values = ["pêches", "épinards", "tomates", "fraises"];

// WRONG: ["fraises", "pêches", "tomates", "épinards"]
values.sort();

 // **GOOD**: ["épinards", "fraises", "pêches", "tomates"]
values.sort(myCompareFunction);

Answer 19

En supposant que vous sachiez ce que vous faites, je suppose que IE6 n'interprète pas correctement le codage du fichier et donc ne reconnaît pas les caractères non-ASCII du fichier:

• Assurez-vous que le fichier est enregistré au format UTF-8 (par exemple)
• Utilisez Fiddler ou un autre outil pour vérifier que le serveur Web envoie le bon en-tête HTTP Content-Encoding.

(Cela "sent" mal, cependant, je voudrais faire du tri, disons sur le serveur en utilisant quelque chose qui tient compte des paramètres régionaux ... mais de toute façon ...) 

Answer 20

J'ai utilisé la méthode latinise () de string.js, qui vous permet de le faire comme ceci:

var output = S(input).latinise().toString();

Answer 21

Le paquet remove-accents NPM est un moyen assez simple de gérer de tels problèmes:

var input = 'ÀÁÂÃÄÅ';
var output = removeAccents(input);

console.log(output); // AAAAAA

$scope.legal_name = $sanitize($scope.legal_name);

Si vous êtes disposé à utiliser une bibliothèque, vous pouvez utiliser String.js latinize: http://stringjs.com/#methods/latinise

Answer 24

Je sais que c’est «tricher» de faire cela côté serveur, mais la semaine dernière, j’avais une tâche similaire en Javascript. J'ai introduit un simple servlet Java et supprimé les accents dans Java . C'était vraiment rapide :)

Answer 25

J'ai trouvé toutes ces choses un peu maladroites et je ne suis pas un expert des expressions régulières. Voici donc une version plus simple. Il serait assez facile de le traduire dans votre langue serveur préférée, en supposant que la chaîne déjà en Unicode:

// String containing replacement characters for stripping accents 
var stripstring = 
    'AAAAAAACEEEEIIII'+
    'DNOOOOO.OUUUUY..'+
    'aaaaaaaceeeeiiii'+
    'dnooooo.ouuuuy.y'+
    'AaAaAaCcCcCcCcDd'+
    'DdEeEeEeEeEeGgGg'+
    'GgGgHhHhIiIiIiIi'+
    'IiIiJjKkkLlLlLlL'+
    'lJlNnNnNnnNnOoOo'+
    'OoOoRrRrRrSsSsSs'+
    'SsTtTtTtUuUuUuUu'+
    'UuUuWwYyYZzZzZz.';

function stripaccents(str){
    var answer='';
    for(var i=0;i<str.length;i++){
        var ch=str[i];
        var chindex=ch.charCodeAt(0)-192;   // Index of character code in the strip string
        if(chindex>=0 && chindex<stripstring.length){
            // Character is within our table, so we can strip the accent...
            var outch=stripstring.charAt(chindex);
            // ...unless it was shown as a '.'
            if(outch!='.')ch=outch;
        }
        answer+=ch;
    }
    return answer;
}

    }
    strAccentsOut = strAccentsOut.join('');
    return strAccentsOut;

Answer 27

Vous pouvez créer des expressions rationnelles de plusieurs façons. Utilisation du nouveau constructeur RegExp-:

var re = new RegExp("[a-z]", "ig") //(string pattern, string modifiers)

Ou en utilisant la notation littérale regex:

var re = /[a-z]/ig; // /pattern/modifiers

Vous avez mélangé les deux.

Answer 28

Cela l'a fait pour moi. JavaScript, scripts Google Apps, GAS

function normalizetext(text) {
  var weird = 'öüóőúéáàűíÖÜÓŐÚÉÁÀŰÍçÇ!@£$%^&*()_+?/*."';
var normalized = 'ouooueaauiOUOOUEAAUIcC                 ';
var idoff = -1,new_text = '';
var lentext = text.toString().length -1

for (i = 0; i <= lentext; i++) {
idoff = weird.search(text.charAt(i));
if (idoff == -1) {
new_text = new_text + text.charAt(i);
} else {
new_text = new_text + normalized.charAt(idoff);
}

}
return new_text;

}
