我在CodeIgniter的一个应用程序上工作,我试图使表单上的字段动态生成URL段塞。我想做的是删除标点符号,将其转换为小写字母,并将空格替换为连字符。比如,Shane's Rib Shack会变成shanes-rib-shack。

这是我目前所掌握的。小写部分很容易,但替换似乎根本不起作用,我也不知道要删除标点符号:

$("#Restaurant_Name").keyup(function() {
  var Text = $(this).val();
  Text = Text.toLowerCase();
  Text = Text.replace('/\s/g','-');
  $("#Restaurant_Slug").val(Text);  
});

当前回答

function slugify(content) {
   return content.toLowerCase().replace(/ /g,'-').replace(/[^\w-]+/g,'');
}
// slugify('Hello World');
// this will return 'hello-world';

这对我来说很好。

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
}

接受的答案没有满足我的需求(它允许下划线,在开头和结尾不处理破折号,等等),而其他答案有其他不适合我的用例的问题,所以这里是我想出的slugify函数:

function slugify(string) {
    return string.trim() // Remove surrounding whitespace.
    .toLowerCase() // Lowercase.
    .replace(/[^a-z0-9]+/g,'-') // Find everything that is not a lowercase letter or number, one or more times, globally, and replace it with a dash.
    .replace(/^-+/, '') // Remove all dashes from the beginning of the string.
    .replace(/-+$/, ''); // Remove all dashes from the end of the string.
}

这将把' foo!!BAR_-_-_baz-'(注意开头的空格)变成foo-bar-baz。

String.prototype.slug = function(e='-'){
  let $this=this
        .toUpperCase()
        .toLowerCase()
        .normalize('NFD')
        .trim()
        .replace(/\s+/g,e)
        .replace(/-\+/g,'')
        .replace(/-+/g,e)
        .replace(/^-/g,'')
        .replace(/-$/g,'')
        .replace(/[^\w-]/g,'');
  return $this
        .toUpperCase()
        .toLowerCase()
        .normalize('NFD')
        .trim()
        .replace(/\s+/g,e)
        .replace(/-\+/g,'')
        .replace(/-+/g,e)
        .replace(/^-/g,'')
        .replace(/-$/g,'')
        .replace(/[^\w-]/g,'');
}

我过滤了两次,因为可能会有更多不需要的字符

我创建了一个插件来实现在大多数语言:http://leocaseiro.com.br/jquery-plugin-string-to-slug/

默认的用法:

$(document).ready( function() {
    $("#string").stringToSlug();
});

是很容易有stringToSlug jQuery插件

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();
}
