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);  
});

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();
}

jQuery.fn.slug = function(options) {
var settings = {
    slug: 'slug', // Class used for slug destination input and span. The span is created on $(document).ready() 
    hide: true   // Boolean - By default the slug input field is hidden, set to false to show the input field and hide the span. 
};

if(options) {
    jQuery.extend(settings, options);
}

$this = $(this);

$(document).ready( function() {
    if (settings.hide) {
        $('input.' + settings.slug).after("<span class="+settings.slug+"></span>");
        $('input.' + settings.slug).hide();
    }
});

makeSlug = function() {
        var slug = jQuery.trim($this.val()) // Trimming recommended by Brooke Dukes - http://www.thewebsitetailor.com/2008/04/jquery-slug-plugin/comment-page-1/#comment-23
                    .replace(/\s+/g,'-').replace(/[^a-zA-Z0-9\-]/g,'').toLowerCase() // See http://www.djangosnippets.org/snippets/1488/ 
                    .replace(/\-{2,}/g,'-'); // If we end up with any 'multiple hyphens', replace with just one. Temporary bugfix for input 'this & that'=>'this--that'
        $('input.' + settings.slug).val(slug);
        $('span.' + settings.slug).text(slug);

    }

$(this).keyup(makeSlug);

return $this;
    };

这帮我解决了同样的问题!

var slug = function(str) {
  str = str.replace(/^\s+|\s+$/g, ''); // trim
  str = str.toLowerCase();

  // remove accents, swap ñ for n, etc
  var from = "ãàáäâẽèéëêìíïîõòóöôùúüûñç·/_,:;";
  var to   = "aaaaaeeeeeiiiiooooouuuunc------";
  for (var i = 0, l = from.length; i < l; i++) {
    str = str.replace(new RegExp(from.charAt(i), 'g'), to.charAt(i));
  }

  str = str.replace(/[^a-z0-9 -]/g, '') // remove invalid chars
           .replace(/\s+/g, '-') // collapse whitespace and replace by -
           .replace(/-+/g, '-'); // collapse dashes

  return str;
};

并尝试

slug($('#field').val())

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

这段代码正在工作

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。

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。
