如何用javascript中的这些符号“aceeisuuz”替换这些符号“ąčęėįšųūž”?我知道我需要使用正则表达式,但我无法制作模式。

这就是我所拥有的

var string = $(this).val();
        string = string.replace(/\s+/g, '-').toLowerCase();
        string = string.replace(/[^a-zA-Z0-9-]/g,'_');
        string = regExp something here...

    $("#custom_url").val(string);

在其他帖子中找到了这个解决方案:

function convert_accented_characters(str){
    var conversions = new Object();
    conversions['ae'] = 'ä|æ|ǽ';
    conversions['oe'] = 'ö|œ';
    conversions['ue'] = 'ü';
    conversions['Ae'] = 'Ä';
    conversions['Ue'] = 'Ü';
    conversions['Oe'] = 'Ö';
    conversions['A'] = 'À|Á|Â|Ã|Ä|Å|Ǻ|Ā|Ă|Ą|Ǎ';
    conversions['a'] = 'à|á|â|ã|å|ǻ|ā|ă|ą|ǎ|ª';

    conversions['c'] = 'ç|ć|ĉ|ċ|č';

    conversions['l'] = 'ĺ|ļ|ľ|ŀ|ł';
    conversions['N'] = 'Ñ|Ń|Ņ|Ň';
    conversions['n'] = 'ñ|ń|ņ|ň|ʼn';
    conversions['O'] = 'Ò|Ó|Ô|Õ|Ō|Ŏ|Ǒ|Ő|Ơ|Ø|Ǿ';
    conversions['o'] = 'ò|ó|ô|õ|ō|ŏ|ǒ|ő|ơ|ø|ǿ|º';

    conversions['ss'] = 'ß';
    conversions['IJ'] = 'IJ';
    conversions['ij'] = 'ij';
    conversions['OE'] = 'Œ';
    conversions['f'] = 'ƒ';

    for(var i in conversions){
        var re = new RegExp(conversions[i],"g");
        str = str.replace(re,i);
    }

    return str;
}

变音符问题? Similar(如果不重复)

尝试这样的事情。除非你捏别人的实现,否则请自己指定它们。匿名类型包含所有转换,我认为这是一个非常简洁的方式。但这是你可能不需要重新发明轮子的事情之一。

  function myReplace(str) {
      var map = {"á":"a", "ç":"c"}
      for (var i in map) {
          str = str.replace(new RegExp(i, "g"), map[i]);
      }
  return str;
  }

顺便说一句,这类问题让我错过了StringBuilder。在这样的循环中编辑str对于大字符串是非常糟糕的。
