如何从字符串中删除重音字符? 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;
};

但是IE6让我很烦,它好像不喜欢我的正则表达式。

从te reo Māori语言中移除宏子 给那些来这里想从马āori语中去掉宏子的人。 注意:当我格式化代码时,Stackblitz删除了map键上的单引号-他们必须确信这是OK的。这个代码的子集,谢谢

'use strict'; var macronMap = { ā: 'a', ē: 'e', ī: 'i', ō: 'o', ū: 'u', Ā: 'A', Ē: 'E', Ī: 'I', Ō: 'O', Ū: 'U', }; function deMacron(str) { return str.replace(/[^A-Za-z0-9\[\] ]/g, function (char) { return macronMap[char] || char; }); } function macronFree(str) { return str === deMacron(str); } console.assert( 'a, e, i, o, u, A, E, I, O, U' === deMacron('ā, ē, ī, ō, ū, Ā, Ē, Ī, Ō, Ū') ); console.assert(macronFree('a, e, i, o, u, A, E, I, O, U')); console.assert(!macronFree('ā, ē, ī, ō, ū, Ā, Ē, Ī, Ō, Ū')); document.body.append(deMacron('ā, ē, ī, ō, ū, Ā, Ē, Ī, Ō, Ū'));

新RegExp的格式为

RegExp(something, 'modifiers');

所以你会想

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;
                };

假设你知道你在做什么,我怀疑IE6没有正确地解释文件的编码,因此不能识别文件中的非ascii字符:

确保文件保存为UTF-8格式(例如) 使用Fiddler或其他工具检查web服务器是否发送正确的内容编码HTTP报头。

(虽然它“闻起来”不对,但我会考虑做排序,比如在服务器上使用一些locale感知的东西……但无论如何…)

如果你也对将希腊字符转换为拉丁语感兴趣,我已经包括了希腊字母和一些有向图;它也可以用来表示正字法和音标相结合的希腊式英语。

此外,该版本接受可选选项:

重写对象{replace:string -> search:regex,…} 它覆盖默认替换 忽略Array<string | regex> |字符串 忽略列表项,列表项可以是字符串或正则表达式

我已经破解了比利的密码 http://jsfiddle.net/billybraga/UHmnf/(来自他的帖子)变成这个:http://jsfiddle.net/infralabs/dJX58/

我纠正了ſ和ß字符的转录,并添加了这些字符的转换:Þþ, Ðð, Ŋŋ, IJij,。
