Efficiently replace all accented characters in a string?
对于穷人在客户端实现近归类正确排序的情况，我需要一个JavaScript函数，该函数可以有效地替换字符串中的单个字符。
这是我的意思(请注意，这适用于德语文本，其他语言则不同)：
1 2 | native sorting gets it wrong: a b c o u z ?¤ ?? ?? collation-correct would be: a ?¤ b c o ?? u ?? z |
基本上，我需要将给定字符串的所有出现的"？¤"都替换为" a"(依此类推)。这样，本机排序的结果将非常接近用户的期望(或数据库将返回的结果)。
其他语言仅具有以下功能：Python提供
这是我现在所拥有的。
1 2 3 4 5 6 7 8 9 10 11 12 | // s would be a rather short string (something like // 200 characters at max, most of the time much less) function makeSortString(s) { var translate = { "?¤":"a","??":"o","??":"u", "??":"A","?–":"O","??":"U" // probably more to come }; var translate_re = /[???¤???–????]/g; return ( s.replace(translate_re, function(match) { return translate[match]; }) ); } |
对于初学者来说，我不喜欢每次调用该函数都会重新构建正则表达式的事实。我猜想闭包可以在这方面有所帮助，但是由于某种原因，我似乎并没有掌握它。
有人能想到更有效的方法吗？

我无法说出您正在尝试对函数本身进行什么操作，但是，如果您不喜欢每次都构建正则表达式，则这里有两个解决方案和一些注意事项。
这里是执行此操作的一种方法：
1 2 3 4 5 6 7 8 9 10 | function makeSortString(s) { if(!makeSortString.translate_re) makeSortString.translate_re = /[???¤???–????]/g; var translate = { "?¤":"a","??":"o","??":"u", "??":"A","?–":"O","??":"U" // probably more to come }; return ( s.replace(makeSortString.translate_re, function(match) { return translate[match]; }) ); } |
这显然会使正则表达式成为函数本身的属性。您对此可能不喜欢的唯一事情(或者您可能会猜到这取决于情况)是，现在可以在函数主体外部修改正则表达式。因此，有人可以这样做来修改相互使用的正则表达式：
1 | makeSortString.translate_re = /[a-z]/g; |
因此，有一个选项。
一种获取闭包(从而防止某人修改正则表达式)的方法是将其定义为匿名函数分配，如下所示：
1 2 3 4 5 6 7 8 9 10 11 12 | var makeSortString = (function() { var translate_re = /[???¤???–????]/g; return function(s) { var translate = { "?¤":"a","??":"o","??":"u", "??":"A","?–":"O","??":"U" // probably more to come }; return ( s.replace(translate_re, function(match) { return translate[match]; }) ); } })(); |
希望这对您有用。
更新：还早，我不知道为什么以前看不到明显的东西，但是将
1 2 3 4 5 6 7 8 9 10 11 12 | var makeSortString = (function() { var translate_re = /[???¤???–????]/g; var translate = { "?¤":"a","??":"o","??":"u", "??":"A","?–":"O","??":"U" // probably more to come }; return function(s) { return ( s.replace(translate_re, function(match) { return translate[match]; }) ); } })(); |
这类口音的正确术语是变音符号。谷歌搜索该术语后，我发现此函数是

str.normalize('NFD').replace(/[\\u0300-\\u036f]/g,"")
> 'Creme Brulee'Two things are happening here:
normalize() ing toNFD Unicode normal form decomposes combined graphemes into the combination of simple ones. The?¨ ofCr?¨me ends up expressed ase +ì€ .Using a regex character class to match the U+0300 a?’ U+036F range, it is now trivial to g lobally get rid of the diacritics, which the Unicode standard conveniently groups as the Combining Diacritical Marks Unicode block.See comment for performance testing.
Alternatively, if you just want sorting

仅应归一化链并运行替换代码：
1 2 3 | var str ="Letras ?? ?‰ ?? ?" ?? ?‘ - ?? ?? ?- ?3 ?o ?±..."; console.log (str.normalize ("NFKD").replace (/[\\u0300-\\u036F]/g,"")); // Letras A E I O U N - a e i o u n... |
请参见规范化
然后您可以使用此功能：
1 2 3 4 5 6 | function noTilde (s) { if (s.normalize != undefined) { s = s.normalize ("NFKD"); } return s.replace (/[\\u0300-\\u036F]/g,""); } |
我认为这可能更干净/更好(尽管我尚未测试其性能)：
1 2 3 4 5 6 7 | String.prototype.stripAccents = function() { var translate_re = /[????￠?￡?¤?§?¨???a?????-???ˉ?±?2?3?′?μ???1?o?????????€?????????????‰?????????????‘?’?"?"???–??????????]/g; var translate = 'aaaaaceeeeiiiinooooouuuuyyAAAAACEEEEIIIINOOOOOUUUUY'; return (this.replace(translate_re, function(match){ return translate.substr(translate_re.source.indexOf(match)-1, 1); }) ); }; |
或者，如果您仍然过于担心性能，让我们两全其美：
1 2 3 4 5 6 7 8 9 | String.prototype.stripAccents = function() { var in_chrs = '????￠?￡?¤?§?¨???a?????-???ˉ?±?2?3?′?μ???1?o?????????€?????????????‰?????????????‘?’?"?"???–??????????', out_chrs = 'aaaaaceeeeiiiinooooouuuuyyAAAAACEEEEIIIINOOOOOUUUUY', transl = {}; eval('var chars_rgx = /['+in_chrs+']/g'); for(var i = 0; i < in_chrs.length; i++){ transl[in_chrs.charAt(i)] = out_chrs.charAt(i); } return this.replace(chars_rgx, function(match){ return transl[match]; }); }; |
编辑(@Tomalak提供)
我很欣赏这个主意。但是，实现存在一些问题，如下面的注释中所述。
这是我要实现的方式。
1 2 3 4 5 6 7 8 9 10 11 12 13 | var stripAccents = (function () { var in_chrs = '????￠?￡?¤?§?¨???a?????-???ˉ?±?2?3?′?μ???1?o?????????€?????????????‰?????????????‘?’?"?"???–??????????', out_chrs = 'aaaaaceeeeiiiinooooouuuuyyAAAAACEEEEIIIINOOOOOUUUUY', chars_rgx = new RegExp('[' + in_chrs + ']', 'g'), transl = {}, i, lookup = function (m) { return transl[m] || m; }; for (i=0; i<in_chrs.length; i++) { transl[ in_chrs[i] ] = out_chrs[i]; } return function (s) { return s.replace(chars_rgx, lookup); } })(); |
基于Jason Bunting的解决方案，这是我现在使用的方法。
整个问题是针对jQuery tablesorter插件的：对于使用tablesorter插件对非英语表进行(几乎正确)排序，必须使用自定义的
这个：
- 将最常见的带重音字母转换为无重音字母(支持的字母列表可以轻松扩展)
-
将德语格式(
'dd.mm.yyyy' )的日期更改为公认的格式('yyyy-mm-dd' )

如果您正在寻找一种将重音字符转换为非重音字符的方法，而不是一种对重音字符进行排序的方法，并且需要一点点改动，则可以使用String.localeCompare函数来查找基本的拉丁字符与扩展的匹配。例如，您可能想从页面标题中生成对人类友好的URL标记。如果是这样，您可以执行以下操作：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 | var baseChars = []; for (var i = 97; i < 97 + 26; i++) { baseChars.push(String.fromCharCode(i)); } //if needed, handle fancy compound characters baseChars = baseChars.concat('ss,aa,ae,ao,au,av,ay,dz,hv,lj,nj,oi,ou,oo,tz,vy'.split(',')); function isUpperCase(c) { return c !== c.toLocaleLowerCase() } function toBaseChar(c, opts) { opts = opts || {}; //if (!('nonAlphaChar' in opts)) opts.nonAlphaChar = ''; //if (!('noMatchChar' in opts)) opts.noMatchChar = ''; if (!('locale' in opts)) opts.locale = 'en'; var cOpts = {sensitivity: 'base'}; //exit early for any non-alphabetical character if (c.localeCompare('9', opts.locale, cOpts) <= 0) return opts.nonAlphaChar === undefined ? c : opts.nonAlphaChar; for (var i = 0; i < baseChars.length; i++) { var baseChar = baseChars[i]; var comp = c.localeCompare(baseChar, opts.locale, cOpts); if (comp == 0) return (isUpperCase(c)) ? baseChar.toUpperCase() : baseChar; } return opts.noMatchChar === undefined ? c : opts.noMatchChar; } function latinify(str, opts) { return str.replace(/[^\\w\\s\\d]/g, function(c) { return toBaseChar(c, opts); }) } // Example: console.log(latinify('??e??tina Ts?—hesen?—stsestotse Tshivená?"a Emigli?na€"Rumagn?2l Sloven????ina Portugu?as Tiáo?ng Viá??t Stra??e')) //"Cestina Tsehesenestsestotse Tshivenda Emigliana€"Rumagnol Slovenscina Portugues Tieng Viet Strasse" |
这应该表现得很好，但是如果需要进一步优化，可以将二进制搜索与
我想不出一种比使用这种惊人的解决方案更简单的方法来有效地从字符串中删除所有变音符号。
查看实际情况：
1 2 3 4 | var string ="???¤???–????"; var string_norm = string.normalize('NFD').replace(/[\\u0300-\\u036f]/g, ''); console.log(string_norm); |
我为此制作了一个原型版：
1 2 3 4 5 6 7 8 9 10 11 | String.prototype.strip = function() { var translate_re = /[???¤???–?????? ]/g; var translate = { "?¤":"a","??":"o","??":"u", "??":"A","?–":"O","??":"U", "":"_","??":"ss" // probably more to come }; return (this.replace(translate_re, function(match){ return translate[match];}) ); }; |
使用方式：
1 2 | var teststring = '?¤ ?? ?? ?? ?– ?? ??'; teststring.strip(); |
这会将字符串更改为a_o_u_A_O_U_ss
基于现有答案和一些建议，我创建了这个答案：

没有一个答案提到
1 2 3 4 5 6 7 | var list = ['a', 'b', 'c', 'o', 'u', 'z', '?¤', '??', '??']; list.sort((a, b) => a.localeCompare(b)); console.log(list); //Outputs ['a', '?¤', 'b', 'c', 'o', '??', 'u', '??', 'z'] |
虽然第二个和第三个参数不受较旧的浏览器支持。尽管如此，这是一个值得考虑的选择。
我只想使用String#localeCompare
发布解决方案

很久以前，我在Java中进行了此操作，找到了基于单个字符串的其他人的解决方案，该字符串捕获了对转换很重要的Unicode表的一部分-其余部分转换为？或任何其他替换字符。因此，我尝试将其转换为JavaScript。请注意，我不是JS专家。 ：-)

这将转换大多数latin1 2 Unicode字符。它无法将单个字符转换为多个字符。我不知道它在JS上的性能，在Java中，这是迄今为止最快的常见解决方案(6-50x)，没有映射，没有正则表达式，什么也没有。它产生严格的ASCII输出，可能会丢失信息，但是输出的大小与输入匹配。
我使用http://www.webtoolkitonline.com/javascript-tester.html测试了代码段，并按预期生成了
如果要实现将"？¤"放在" a"之后而不是被视为不相同的排序，则可以使用像我的函数。
您始终可以更改字母以进行不同甚至奇怪的排序。但是，如果您希望某些字母等效，那么您就必须操纵像
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | function sortbyalphabet(a,b) { alphabet ="0123456789Aa?€????????￠???￡???¤BbCc???§Dd???¨?‰?????a????FfGgHh???????-???????ˉJjKkLlMmNn?‘?±Oo?’?2?"?3?"?′???μ?–??PpQqRrSsTt???1???o????????VvWwXx????????Zz"; a = a.toLowerCase(); b = b.toLowerCase(); shorterone = (a.length > b.length ? a : b); for (i=0; i<shorterone.length; i++){ diff = alphabet.indexOf(a.charAt(i)) - alphabet.indexOf(b.charAt(i)); if (diff!=0){ return diff; } } // sort the shorter first return a.length - b.length; } var n = ["ast","??ste","apfel","?¤pfel","?"]; console.log(n.sort(sortbyalphabet)); // should return ["apfel","ast","?","?¤pfel","?¤ste"] |
一种简单的方法：
1 2 3 | function remove-accents(p){ c='????￡?￠?¤???¨?a???-?????ˉ?3?2?μ?′???o?1?????§???€???????‰???????????????"?’???–?"??????????';s='aaaaaeeeeiiiiooooouuuucAAAAAEEEEIIIIOOOOOUUUUC';n='';for(i=0;i<p.length;i++){if(c.search(p.substr(i,1))>=0){n+=s.substr(c.search(p.substr(i,1)),1);} else{n+=p.substr(i,1);}} return n; } |
这样做：
1 | remove-accents("Th?-s ?-s ?￠n acc?ant??d phr??se"); |
输出：
1 | "This is an accented phrase" |
克里斯·卡林(Answer os Crisalin)几乎是完美的。只是提高了性能，以避免在每次运行时都创建新的RegExp。

如果您愿意，我已经用另一种方式解决了它。
在这里我使用了两个数组，其中将替换包含searchChars的数组和包含所需字符的replaceChars。
1 2 3 4 5 6 7 8 9 10 | var text ="your input string"; var searchChars = ['?…','??','?￥','?–','??']; // add more charecter. var replaceChars = ['A','A','a','O','o']; // exact same index to searchChars. var index; for (var i = 0; i < text.length; i++) { if( $.inArray(text[i], searchChars) >-1 ){ // $.inArray() is from jquery. index = searchChars.indexOf(text[i]); text = text.slice(0, i) + replaceChars[index] + text.slice(i+1,text.length); } } |
