还有一个。短且保留特殊字符:

想象力是丛林=>想象力和丛林

function slugify (text) {
  const a = 'àáäâãèéëêìíïîòóöôùúüûñçßÿœæŕśńṕẃǵǹḿǘẍźḧ·/_,:;'
  const b = 'aaaaaeeeeiiiioooouuuuncsyoarsnpwgnmuxzh------'
  const p = new RegExp(a.split('').join('|'), 'g')

  return text.toString().toLowerCase()
    .replace(/\s+/g, '-')           // Replace spaces with -
    .replace(p, c =>
        b.charAt(a.indexOf(c)))     // Replace special chars
    .replace(/&/g, '-and-')         // Replace & with 'and'
    .replace(/[^\w\-]+/g, '')       // Remove all non-word chars
    .replace(/\-\-+/g, '-')         // Replace multiple - with single -
    .replace(/^-+/, '')             // Trim - from start of text
    .replace(/-+$/, '')             // Trim - from end of text
}

private string ToSeoFriendly(string title, int maxLength) {
    var match = Regex.Match(title.ToLower(), "[\\w]+");
    StringBuilder result = new StringBuilder("");
    bool maxLengthHit = false;
    while (match.Success && !maxLengthHit) {
        if (result.Length + match.Value.Length <= maxLength) {
            result.Append(match.Value + "-");
        } else {
            maxLengthHit = true;
            // Handle a situation where there is only one word and it is greater than the max length.
            if (result.Length == 0) result.Append(match.Value.Substring(0, maxLength));
        }
        match = match.NextMatch();
    }
    // Remove trailing '-'
    if (result[result.Length - 1] == '-') result.Remove(result.Length - 1, 1);
    return result.ToString();
}

将这里的答案中的各种元素与normalize结合起来可以提供很好的覆盖率。保持操作的顺序，以增量地清理url。

function clean_url(s) {
    return s.toString().normalize('NFD').replace(/[\u0300-\u036f]/g, "") //remove diacritics
            .toLowerCase()
            .replace(/\s+/g, '-') //spaces to dashes
            .replace(/&/g, '-and-') //ampersand to and
            .replace(/[^\w\-]+/g, '') //remove non-words
            .replace(/\-\-+/g, '-') //collapse multiple dashes
            .replace(/^-+/, '') //trim starting dash
            .replace(/-+$/, ''); //trim ending dash
}

normize ('NFD')将重音字符分解为它们的组成部分，即基本字母加上变音符符号(重音部分)。Replace (/[\u0300-\u036f]/g， "")清除所有变音符，只保留基本字母。其余部分用内联注释解释。

我不知道“鼻涕虫”这个词从何而来，但我们开始吧:

function convertToSlug(Text) {
  return Text.toLowerCase()
             .replace(/ /g, '-')
             .replace(/[^\w-]+/g, '');
}

第一个replace方法将空格更改为连字符，第二，replace删除除字母数字、下划线或连字符以外的任何内容。

如果你不希望“like- this”变成“like- this”，你可以用这个:

function convertToSlug(Text) {
  return Text.toLowerCase()
             .replace(/[^\w ]+/g, '')
             .replace(/ +/g, '-');
}

这将在第一次替换时删除连字符(但没有空格)，在第二次替换时将连续的空格压缩为单个连字符。

所以"like-this"就变成了"like-this"。

首先，正则表达式不应该有引号，所以'/\s/g'应该是/\s/g

为了用破折号替换所有非字母数字字符，这应该可以工作(使用示例代码):

$("#Restaurant_Name").keyup(function() {
  var Text = $(this).val();
  Text = Text.toLowerCase();
  Text = Text.replace(/[^a-zA-Z0-9]+/g,'-');
  $("#Restaurant_Slug").val(Text);        
});

这应该能奏效……
