                        return r;
                };

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: correction de la non-code de travail

une solution qui semble être beaucoup plus rapide par l'essai 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 pratique: http://jsbin.com/sovorute/1/edit

raisonnement : une raison pour laquelle cela est beaucoup plus rapide est parce que nous itérons seulement à travers les caractères spéciaux, choisis par le modèle de regex nié. Le plus rapide des tests ( chaîne Itération Sans dans ) itère 1001 sur le texte donné, qui signifie chaque caractère . Celui-ci itère seulement 35 fois et produit le même résultat . Gardez à l'esprit que cela ne remplacera que ce qui est indiqué sur la carte.

j'ai forké billy le code de http://jsfiddle.net/billybraga/UHmnf/ (à partir de son post ): http://jsfiddle.net/infralabs/dJX58/

j'ai corrigé la transcription des caractères , et ß et j'ai ajouté la couverture de ceux-ci: Þþ , Ðð , " , , , , .

vous pouvez utiliser la méthode Deburr de la bibliothèque Lodash.

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

Le résultat sera : "Mon café hne plein de cafeine"

Cependant, j'ai essayé cette méthode avec les caractères suivants : "Àáâãäåàáâãäåòóôõõöøøòóôõöøèéêëèéêëðççðìíîïìíîïùúûüùúûüññšÿÿÿžžž

Et les caractères suivants n'ont pas été changer : "ŠšŸŽž "

mais dans la plupart des langues ils ne sont pas utilisés à tous, donc, je pense que cette méthode est l'une des meilleures.

dans NPM il y a un paquet pour cela: latinize

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

Voici ma version modifiée de lehelk.com 'version qui supprime également les entités html qui sont les accents :

Je ne suis pas encore au courant de la performance...

Voici une solution très simple sans trop de code en utilisant une carte très simple de diacritiques qui inclut une partie ou la totalité de cette carte à des équivalents ascii contenant plus d'un caractère, i.e. Æ => AE, ffi => ffi, etc...

var diacriticsMap = {
  '\u00C0': 'A',  // À => A
  '\u00C1': 'A',   // Á => A
  '\u00C2': 'A',   // Â => A

  '\u00CE': 'I',   // Î => I
  '\u00CF': 'I',   // Ï => I
  '\u0132': 'IJ', // IJ => IJ
  '\u00D0': 'D',   // Ð => D

  '\u00D2': 'O',   // Ò => O
  '\u00D3': 'O',   // Ó => O
  '\u00D4': 'O',   // Ô => O
  '\u00D5': 'O',   // Õ => O
  '\u00D6': 'O',   // Ö => O
  '\u00D8': 'O',   // Ø => O

  '\u00E2': 'a',   // â => a
  '\u00E3': 'a',   // ã => a
  '\u00E4': 'a',   // ä => a
  '\u00E5': 'a',   // å => a
  '\u00E6': 'ae', // æ => ae
  '\u00E7': 'c',   // ç => c
  '\u00E8': 'e',   // è => e
  '\u00E9': 'e',   // é => e
  '\u00EA': 'e',   // ê => e
  '\u00EB': 'e',   // ë => e
  '\u00EC': 'i',   // ì => i
  '\u00ED': 'i',   // í => i
  '\u00EE': 'i',   // î => i
  '\u00EF': 'i',   // ï => i
  '\u0133': 'ij', // ij => ij
  '\u00F0': 'd',   // ð => d
  '\u00F1': 'n',   // ñ => n
  '\u00F2': 'o',   // ò => o
  '\u00F3': 'o',   // ó => o
  '\u00F4': 'o',   // ô => o
  '\u00F5': 'o',   // õ => o
  '\u00F6': 'o',   // ö => o
  '\u00F8': 'o',   // ø => o
  '\u0153': 'oe', // œ => oe
  '\u00DF': 'ss', // ß => ss
  '\u00FE': 'th', // þ => th
  '\u00F9': 'u',   // ù => u
  '\u00FA': 'u',   // ú => u
  '\u00FB': 'u',   // û => u

  '\uFB01': 'fi',   // fi => fi
  '\uFB02': 'fl', // fl => fl
  '\uFB03': 'ffi',  // ffi => ffi
  '\uFB04': 'ffl',  // ffl => ffl
  '\uFB05': 'ft', // ſt => ft
  '\uFB06': 'st'  // st => st
};

function replaceDiacritics(str) {
  var returnStr = '';
  if(str) {
    for (var i = 0; i < str.length; i++) {
      if (diacriticsMap[str[i]]) {
        returnStr += diacriticsMap[str[i]];
      } else {
        returnStr += str[i];
      }
    }
  }
  return returnStr;
}

function testStripDiacritics(input, expected) {
  var coChar = replaceDiacritics(input);
  console.log('The character passed in was ' + input);
  console.log('The character that came out was ' + coChar);
  console.log('The character expected was' + expected);

testStripDiacritics('À','A');
testStripDiacritics('A','A');
testStripDiacritics('Æ','AE');
testStripDiacritics('AE','AE');
testStripDiacritics('ÇhÀrlËšYŸZŽ','ChArlEsYYZZ');

une façon plus simple de remplacer les diacritiques.

function replaceDiacritics(str){

  var diacritics = [
    {char: 'A', base: /[0-6]/g},
    {char: 'a', base: /[0-6]/g},
    {char: 'E', base: /[0-3]/g},
    {char: 'e', base: /[0-3]/g},
    {char: 'I', base: /[4-7]/g},
    {char: 'i', base: /[4-7]/g},
    {char: 'O', base: /[2-0]/g},
    {char: 'o', base: /[2-0]/g},
    {char: 'U', base: /[1-4]/g},
    {char: 'u', base: /[1-4]/g},
    {char: 'N', base: /[1]/g},
    {char: 'n', base: /[1]/g},
    {char: 'C', base: /[7]/g},
    {char: 'c', base: /[7]/g}
  ]

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

  return str;
};

merci à tous

J'utilise cette version et dire pourquoi (parce que je manque des explications au début, j'ai donc essayer d'aider le prochain lecteur s'il est aussi terne 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:

(il n'y a pas de nouvelle astuce technique à l'intérieur, seuls quelques élus + explications)

makeSortString = (function() {
    var translate_re = /[¹²³áàâãäåaaaÀÁÂÃÄÅAAAÆccç©CCÇÐÐèéê?ëeeeeeÈÊË?EEEEE€gGiìíîïìiiiÌÍÎÏ?ÌIIIlLnnñNNÑòóôõöoooøÒÓÔÕÖOOOØŒr®Ršs?ߊS?ùúûüuuuuÙÚÛÜUUUUýÿÝŸžzzŽZZ]/g;
    var translate = {
"¹":"1","²":"2","³":"3","á":"a","à":"a","â":"a","ã":"a","ä":"a","å":"a","a":"a","a":"a","a":"a","À":"a","Á":"a","Â":"a","Ã":"a","Ä":"a","Å":"a","A":"a","A":"a",

    };
    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:

• Tl'instruction à l'intérieur il est fait une fois (après, makeSortString != Non défini)
• fonction(){...} est stocké une fois dans makeSortString, "big" translate_re et les objets translate sont stockés une fois
• quand vous appelez makeSortString('something') il appelle directement la fonction inside qui appelle seulement S. remplacer(...) : il est efficace
• S. remplacer utilise regexp (la syntaxe spéciale de var translate_re= .... est en fait équivalent à var translate_re = new RegExp ("[1....Z]", "g"); mais la compilation du regexp est faite une fois pour toutes, et le scan de la chaîne s est fait une fois pour un appel du fonction (pas pour chaque personnage, comme il le serait dans une boucle)
• pour chaque caractère trouvé par.remplacer la fonction calls (match) où le paramètre match contient le caractère trouvé, et l'appeler le caractère traduit correspondant (translate [match])
• Translate [match] est probablement efficace aussi car l'objet JavaScript translate est probablement implémenté par javascript avec un hashtab ou quelque chose d'équivalent et permet au programme de trouver la traduction caractère presque directement et pas par exemple à travers une boucle sur un tableau de tous les caractères pour trouver le bon (qui serait terriblement inefficace).

je fournis cette réponse pour une question similaire. Il est basé sur le remplacement rapide de la table-recherche pour les chars sélectionnés (latin 1+2), Un pour un (pas possible de changer l'Allemand ü À "ue"), mais fonctionne bien pour la "normalisation" de base à 7-bit ASCII.

stripDiacritics("Šupa, čo? ľšťčžýæøåℌð")

les autres caractères sont convertis ?, qui est le résultat est certainement 7-bit ASCII. Pas de regex, pas de magie, un simple char array.

en supposant que vous savez ce que vous faites, je soupçonne que IE6 n'interprète pas correctement l'encodage du fichier, et donc ne reconnaît pas les caractères non-ASCII dans le fichier:

• assurez-vous que le fichier est sauvegardé comme UTF-8 (say)
• utilisez Fiddler ou un autre outil pour vérifier que le serveur web envoie le bon en-tête HTTP de codage de contenu.

tri, disons sur le serveur en utilisant quelque chose qui est sensible à la localisation... mais de toute façon...)

passer une fonction définie par l'utilisateur à la Array.sort() méthode, et dans cette fonction définie par l'Utilisateur utiliser 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);

j'ai utilisé de la ficelle.la méthode DE JS latinise () , qui vous permet de le faire comme ceci:

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

il y a beaucoup de choses là-bas, mais je pense que celle-ci est simple et assez bonne:

 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 voulez aussi supprimer des caractères spéciaux et transformer des espaces et des traits d'Union dans les underscores, faites ceci:

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

function removeAccents(strAccents){
    strAccents = strAccents.split('');
    strAccentsOut = new Array();
    strAccentsLen = strAccents.length;
    var accents = 'ÀÁÂÃÄÅàáâãäåÒÓÔÕÕÖØòóôõöøÈÉÊËèéêëðÇçÐÌÍÎÏìíîïÙÚÛÜùúûüÑñŠšŸÿýŽž';
    var accentsOut = ['A','A','A','A','A','A','a','a','a','a','a','a','O','O','O','O','O','O','O','o','o','o','o','o','o','E','E','E','E','e','e','e','e','e','C','c','D','I','I','I','I','i','i','i','i','U','U','U','U','u','u','u','u','N','n','S','s','Y','y','y','Z','z'];
    for (var y = 0; y < strAccentsLen; y++) {
        if (accents.indexOf(strAccents[y]) != -1) {
            strAccentsOut[y] = accentsOut[accents.indexOf(strAccents[y])];
        }
        else
            strAccentsOut[y] = strAccents[y];
    }
    strAccentsOut = strAccentsOut.join('');
    return strAccentsOut;
}

je sais qu'il est" tricher "de faire cela du côté du serveur, mais la semaine dernière j'ai eu une tâche similaire en Javascript et j'ai introduit un servlet java simple et enlevé les accents en Java . C'était très rapide :)

j'ai trouvé tout cela un peu maladroit et je ne suis pas trop expert sur les expressions régulières, donc voici une version plus simple. Il serait assez facile de le traduire dans votre langue préférée côté serveur, en supposant que la chaîne de caractères 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;
}

vous pouvez créer des regex de plusieurs façons. En utilisant le nouveau RegExp - constructeur:

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.

si vous êtes ouvert à l'utilisation d'une bibliothèque, vous pouvez utiliser String.js latinize: http://stringjs.com/#methods/latinise

$scope.legal_name = $sanitize($scope.legal_name);
    console.log("Name before function...",$scope.legal_name);

    var str = "";
    for(var i=0; i < $scope.legal_name.length; i++) {
        var charName = $scope.legal_name.charAt(i);
        if((charName == '&') && ($scope.legal_name.charAt(i + 1) == '#')){
            var count = 0;
            var subString = "";
            while(true) {
                if(($scope.legal_name.charCodeAt(i + 2 + count) > 47) && ($scope.legal_name.charCodeAt(i + 1 + count) < 58 )) {
                    subString = subString + $scope.legal_name.charAt(i + 2 + count);
                    count++;
                } else {
                    if(subString.length > 0) {
                        var value = parseInt(subString);
                        str = str + String.fromCharCode(value);
                        i = i + 1 + count; 
                        break;
                    }
                }
            }               
        } else {
            str = str + charName;
        }
    }
    $scope.legal_name = str;
    console.log("Name After function...",str);

le supprimer-accents paquet NPM est un moyen assez facile de traiter de telles questions:

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

console.log(output); // AAAAAA

pour moi. JavaScript, Google Apps Scripts ,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;

}

Tout ce qui précède ne fonctionne pas avec le caractère décomposé comme utilisé sur Mac OS. Pour supprimer les diacritiques dans ce cas, il est plus simple:

r = r.replace(new RegExp(/[\u0300-\u036f]/g),"")
