在JavaScript中删除string中的重音/变音符号

如何从string中删除突出的字符？ 特别是在IE6中，我有这样的东西：

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; }; 

但IE6错误的，似乎不喜欢我的正则expression式。

Answer 1

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

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

这里发生了两件事情：

1. normalize()到NFD Unicode规范forms将组合的字素分解成简单的组合。 Crème的è最终expression为e + ̀
2. 使用正则expression式字符类来匹配U + 0300→U + 036F范围，现在可以摆脱Unicode标准方便地组合为Diagritical Marks Unicode块的变音符号 。

请参阅性能testing评论。

Answer 2

我稍微修改了khel版本的原因之一：每个正则expression式parsing/replace将花费O（n）操作，其中n是目标文本中的字符数。 但是，正则expression式并不是我们所需要的。 所以：

Answer 5

The format for new RegExp is

 RegExp(something, 'modifiers'); 

So you would want

 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; }; 

Answer 6

Shortened code based on the excellent solution by 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: Corrected non-working code

Answer 7

I have forked billy 's code http://jsfiddle.net/billybraga/UHmnf/ (from his post ) into this: http://jsfiddle.net/infralabs/dJX58/

I corrected transcription of ſ and ß characters and also added coversion of these ones: Þþ , Ðð , Ŋŋ , IJij , Œœ .

Answer 8

UPDATE April 6 2014 : Removed false information based on broken test. 对不起。 Use @rdllopez's unicode range solution.

One solution that seems to be way faster by the given test :

See the jsPerf : 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); 

Working example: http://jsbin.com/sovorute/1/edit

Reasoning : One reason this is much faster is because we only iterate through the special characters, picked by the negated regex pattern. The fastest of the tests ( String Iteration without in ) iterates 1001 on the given text, which means every character . This one iterates only 35 times and outputs the same result . Keep in mind that this will only replace what is indicated in the map.

Classic article on the subject: http://alistapart.com/article/accent-folding-for-auto-complete

Credit : http://semplicewebsites.com/removing-accents-javascript , also provides a nice character map.

Answer 9

Here's my modified version of lehelk.com 's version that also removes html entites that are accents :

Answer 10

thanks to all
I use this version and say why (because I misses those explanations at the begining, so I try to help the next reader if he is as dull as me …)

Remark : I wanted an efficient solution, so :

• only one regexp compilation (if needed)
• only one string scan for each string
• an efficient way to find the translated characters etc …

My version is :
(there is no new technical trick inside it, only some selected ones + explanations why)

 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", "A":"a","Æ":"a","c":"c","c":"c","ç":"c","©":"c","C":"c","C":"c","Ç":"c","Ð":"d","Ð":"d","è":"e","é":"e","ê":"e","?":"e","ë":"e","e":"e","e":"e","e":"e","e":"e", "e":"e","È":"e","Ê":"e","Ë":"e","?":"e","E":"e","E":"e","E":"e","E":"e","E":"e","€":"e","g":"g","G":"g","i":"i","ì":"i","í":"i","î":"i","ï":"i","ì":"i","i":"i", "i":"i","i":"i","Ì":"i","Í":"i","Î":"i","Ï":"i","?":"i","Ì":"i","I":"i","I":"i","I":"i","l":"l","L":"l","n":"n","n":"n","ñ":"n","N":"n","N":"n","Ñ":"n","ò":"o", "ó":"o","ô":"o","õ":"o","ö":"o","o":"o","o":"o","o":"o","ø":"o","Ò":"o","Ó":"o","Ô":"o","Õ":"o","Ö":"o","O":"o","O":"o","O":"o","Ø":"o","Œ":"o","r":"r","®":"r", "R":"r","š":"s","s":"s","?":"s","ß":"s","Š":"s","S":"s","?":"s","ù":"u","ú":"u","û":"u","ü":"u","u":"u","u":"u","u":"u","u":"u","Ù":"u","Ú":"u","Û":"u","Ü":"u", "U":"u","U":"u","U":"u","U":"u","ý":"y","ÿ":"y","Ý":"y","Ÿ":"y","ž":"z","z":"z","z":"z","Ž":"z","Z":"z","Z":"z" }; return function(s) { return(s.replace(translate_re, function(match){return translate[match];}) ); } })(); 

and I use it this way :

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

注释 ：

• Tthe instruction inside it is done once (after, makeSortString != undefined)
• function(){…} is stored once in makeSortString, so the "big" translate_re and translate objects are stored once
• When you call makeSortString('something') it call directly the inside function which calls only s.replace(…) : it is efficient
• s.replace uses regexp (the special syntax of var translate_re= …. is in fact equivalent to var translate_re = new RegExp("[¹….Z]","g"); but the compilation of the regexp is done once for all, and the scan of the s String is done one for a call of the function (not for every character as it would be in a loop)
• For each character found s.replace calls function(match) where parameter match contains the character found, and it call the corresponding translated character (translate[match])
• Translate[match] is probably efficient too as the javascript translate object is probably implemented by javascript with a hashtab or something equivalent and allow the program to find the translated character almost directly and not for instance through a loop on a array of all characters to find the right one (which would be awfully unefficient).

Answer 11

In NPM exist a packege for this: latinize

I recommend the use due to easy deployment.

Answer 12

Here's a very simple solution without too much code using a very simple map of diacritics that includes some or all that map to ascii equivalents containing more than one character, ie Æ => AE, ffi => ffi, etc… Also included some very basic functional tests

 var diacriticsMap = { '\u00C0': 'A', // À => A '\u00C1': 'A', // Á => A '\u00C2': 'A', //  => A '\u00C3': 'A', // à => A '\u00C4': 'A', // Ä => A '\u00C5': 'A', // Å => A '\u00C6': 'AE', // Æ => AE '\u00C7': 'C', // Ç => C '\u00C8': 'E', // È => E '\u00C9': 'E', // É => E '\u00CA': 'E', // Ê => E '\u00CB': 'E', // Ë => E '\u00CC': 'I', // Ì => I '\u00CD': 'I', // Í => I '\u00CE': 'I', // Î => I '\u00CF': 'I', // Ï => I '\u0132': 'IJ', // IJ => IJ '\u00D0': 'D', // Ð => D '\u00D1': 'N', // Ñ => N '\u00D2': 'O', // Ò => O '\u00D3': 'O', // Ó => O '\u00D4': 'O', // Ô => O '\u00D5': 'O', // Õ => O '\u00D6': 'O', // Ö => O '\u00D8': 'O', // Ø => O '\u0152': 'OE', // Œ => OE '\u00DE': 'TH', // Þ => TH '\u00D9': 'U', // Ù => U '\u00DA': 'U', // Ú => U '\u00DB': 'U', // Û => U '\u00DC': 'U', // Ü => U '\u00DD': 'Y', // Ý => Y '\u0178': 'Y', // Ÿ => Y '\u00E0': 'a', // à => a '\u00E1': 'a', // á => a '\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 '\u00FC': 'u', // ü => u '\u00FD': 'y', // ý => y '\u00FF': 'y', // ÿ => y '\uFB00': 'ff', // ff => ff '\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'); 

Answer 13

A simpler way to replace the diacriticals.

 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; }; 

Answer 14

You can use the Deburr method from the Lodash library.

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

The result will be : "Mon cafe est plein de cafeine"

However, I tried this method with the following characters : "ÀÁÂÃÄÅàáâãäåÒÓÔÕÕÖØòóôõöøÈÉÊËèéêëðÇçÐÌÍÎÏìíîïÙÚÛÜùúûüÑñŠšŸÿýŽž"

And the following characters were not change : "ŠšŸŽž"

But in most languages they are not used at all, so I think this method is one of the best.

Answer 15

Assuming you know what you're doing, I suspect IE6 is not interpreting the file's encoding correctly, and hence not recognising the non-ASCII characters in the file:

• Make sure the file is saved as UTF-8 (say)
• Use Fiddler or some other tool to check that the web server is sending the correct Content-Encoding HTTP header.

(It "smells" wrong though, I'd look into doing the sorting, say on the server using something that's locale-aware… but anyway…)

Answer 16

Pass a user defined function to the Array.sort() method, and in this user defined function use 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 17

You can create regex's in multiple ways. Using the new RegExp -constructor:

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

Or using the regex literal notation:

 var re = /[az]/ig; // /pattern/modifiers 

You have mixed the two.

Answer 18

I provided this answer for a similar question. It is based on quick table-lookup replacement for selected chars (latin 1+2), one for one (not possible to change German ü to "ue"), but works well for basic "normalization" to 7-bit ASCII.

 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") 

Any other characters are converted to ?, that is result is definitely 7-bit ASCII. No regex, no magic, simple char array work.

Answer 19

I used string.js's latinise() method, which lets you do it like this:

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

Answer 20

 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; } 

Answer 21

I know it is "cheating" to do this on the server side, but last week I had a similar task in Javascript and I've introduced a simple java servlet and removed the accents in Java . It was really fast 🙂

Answer 22

I found all these a little clumsy and I'm not too expert on regular expressions, so here's a simpler version. It would be quite easy to translate it to your favourite server-side language, assuming that the string already in 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; } 

Answer 23

If you are open to using a library, you can use String.js latinize: http://stringjs.com/#methods/latinise

Answer 24

 $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); 

Answer 25

All the above isn't working with decomposed character as used on Mac OS. In order to remove diacritics in that case it is more simple :

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