在JavaScript中删除字符串中的重音/变音符号

新RegExp的格式是

RegExp(something, 'modifiers');

所以你会想要

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;
};

您可以通过多种方式创建正则表达式。使用新的RegExp构造函数：

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

或者使用regex文字表示法：

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

你把两者混为一谈。

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;
}

假设您知道自己在做什么，我怀疑IE6没有正确解释文件的编码，因此无法识别文件中的非ASCII字符：

• 确保文件保存为UTF-8（说）
• 使用Fiddler或其他工具检查Web服务器是否发送了正确的Content-Encode HTTP标头。

（虽然它“闻起来”不对，但我会考虑进行排序，比如在服务器上使用语言环境感知的东西……但无论如何……）

我发现所有这些都有点笨拙，而且我不是正则表达式的专家，所以这里有一个更简单的版本。假设字符串已经在Unicode中，将其翻译成您最喜欢的服务器端语言会很容易：

// 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;
}

一个更完整的版本，支持区分大小写，连接等。 原文来源：http://lehelk.com/2011/05/06/script-to-remove-diacritics/

将用户定义的函数传递给 Array.sort()方法，并在此用户定义函数中使用 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);

基于 Ian Elliott 的优秀解决方案的简化代码:

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;
};

编辑: 更正的非工作代码

我稍微修改了 khelversion 的一个原因是: 每个 regexp 解析/替换都将花费 O (n)操作，其中 n 是目标文本中的字符数。但是，regexp 并不是我们所需要的。所以:

所有这些都不适用于 Mac OS 中使用的分解字符。 在这种情况下，为了消除变音符号，更简单的做法是:

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

参见 Olivier Miakinen 的评论: Https://groups.google.com/d/msg/fr.comp.lang.regexp/6igjtbedgtm/g0sb2kasr34j (法文)

通过给定的测试，有一个解决方案似乎要快得多: 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);

工作示例: http://jsbin.com/sovorute/1/edit

推理 : 这样做更快的一个原因是，我们只迭代由否定的 regex 模式选择的特殊字符。最快的测试(没有 in 的字符串迭代)在给定的文本上迭代1001，这意味着 每个角色。这个函数只迭代35次并输出 同样的结果。请记住，这只会取代什么是指示在地图上。

感谢所有人
我使用了这个版本并解释了原因(因为我在开始的时候忽略了这些解释，所以如果下一位读者和我一样无聊的话，我会试着帮助他... ...)

备注: 我想要一个有效的解决方案，所以:

• 只进行一次 regexp 编译(如果需要)
• 对每个字符串只进行一次字符串扫描
• 找到翻译字符的有效方法 等等。

我的版本是:
(里面没有新的技术把戏，只有一些精选的 + 解释为什么)

makeSortString = (function() {
var translate_re = /[¹²³áàâãäåaaaÀÁÂÃÄÅAAAÆccç©CCÇÐÐèéê?ëeeeeeÈÊË?EEEEE€gGiìíîïìiiiÌÍÎÏ?ÌIIIlLnnñNNÑòóôõöoooøÒÓÔÕÖOOOØŒr®Ršs?ߊS?ùúûüuuuuÙÚÛÜUUUUýÿÝŸžzzŽZZ]/g;
var translate = {

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

我是这样使用它的:

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

评论:

• 它内部的指令执行一次(之后，maSortString! = 未定义)
• Function (){ ... }在 makeSortString 中只存储一次，因此“ big”trans _ re 和 trans 对象只存储一次
• 当您调用 makSortString (‘ something’)时，它直接调用内部函数，该函数只调用 s.place (...) : 它是有效的
• Place 使用 regexp (var trans _ re = ... 的特殊语法。实际上等效于 var trans _ re = new RegExp (“[1... . Z ]”，“ g”) ; 但 RegExp 的编译是一次性的，s String 的扫描是一次性的，用于函数的调用(不是对循环中的每个字符)
• 对于每个找到的字符，s.place 调用函数(match) ，其中的参数 match 包含找到的字符，并调用相应的翻译字符(trans [ match ])
• Translate [ match ]可能也是有效的，因为 javascript 翻译对象可能是由 javascript 用 hashtab 或其他等价物实现的，并且允许程序几乎直接找到翻译的字符，而不是通过对所有字符数组的循环来找到正确的字符(这将是非常低效的)。

这是一个非常简单的解决方案，没有太多的代码，使用一个非常简单的变音符映射，包括一些或所有的映射到包含多个字符的 ascii 等价物，即 Æ = > AE，ffi = > ffi，等等。.还包括一些非常基本的功能测试

在 NPM 中有一个这样的软件包: 拉丁化

这是解决这个问题的一个很好的方案。

$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);

一种更简单的替换发音的方法。

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;
};

ES2015/ES6Prototype.norize (),

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

注意: 使用 NFKD如果你想像 \uFB01(fi)标准化(到 fi)的东西。

这里发生了两件事:

1. 从 normalize()到 NFD Unicode 范式将组合图形分解为简单图形的组合。Crème的 è最终表达为 e + ̀。
2. 使用正则表达式 性格类来匹配 U + 0300→ U + 036F 范围，现在在全局上去掉变音符已经很容易了，Unicode 标准方便地将这些变音符组合为 组合发音符号 Unicode 块。

到2021年，人们还可以使用 Unicode 属性转义:

str.normalize("NFD").replace(/\p{Diacritic}/gu, "")

有关性能测试，请参见注释。

或者，如果您只想排序

Collator 有足够的支持 95% ，填充料也可以使用 给你，但是我还没有测试过。

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"]

我使用了 string.js 的 (拉丁语)方法，它允许您这样做:

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

你可以使用 Lodash 图书馆的 _.deburr()方法。

它可以作为独立的 NPM 软件包 lodash.deburr，或者作为 lodash软件包的一部分。

const myStringWithAccent = 'Mon café est plein de caféïne';
const myStringWithoutAccent = _.deburr( myStringWithAccent, );

结果将是: "Mon cafe est plein de cafeine"

外面有很多东西，但我认为这个很简单，也足够好:

 function remove_accents(strAccents) {
var strAccents = strAccents.split('');
var strAccentsOut = new Array();
var strAccentsLen = strAccents.length;
var accents =    "ÀÁÂÃÄÅàáâãäåÒÓÔÕÕÖØòóôõöøÈÉÊËèéêëÇçðÐÌÍÎÏìíîïÙÚÛÜùúûüÑñŠšŸÿýŽž";
var accentsOut = "AAAAAAaaaaaaOOOOOOOooooooEEEEeeeeCcdDIIIIiiiiUUUUuuuuNnSsYyyZz";
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;
}

如果还希望删除特殊字符并转换下划线中的空格和连字符，请执行以下操作:

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

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;


}

测试了从字符串中删除符号的 最快的方法 几乎涵盖了所有的角色，这是最好的表演方法

使用

function removeDicretics(str) {
return str.replace(/[^\u0000-\u007E]/g, function (weirdo) {

}
// Call
var cleanStr = removeDicretics("bułłśhìt"); // bullshit

我的看法是，删除所有重音符号和特殊字符。我混合了 Lewis Diamond 的优雅口音去除方法和社区 wiki 的快速字符替换其余字符。结果是一个 Ascii 字符串。

Normal ize-diacritics 非常有用

/** Assuming top-level await is enabled... */
await normalize('söme stüff with áccènts'); // 'some stuff with accents'

我使用 GitHub Jakub Dundalek 的存储库 拉丁文。

var latinize = require('latinize');
latinize('ỆᶍǍᶆṔƚÉ áéíóúýčďěňřšťžů'); // => 'ExAmPlE aeiouycdenrstzu'
