How to convert a Title to a URL slug in jQuery?

I'm working on an app in CodeIgniter, and I'm trying to make a field on a form dynamically generate the URL slug. What I'd like to do is remove the punctuation, convert it to lowercase, and replace the spaces with hyphens. So for example, Shane's Rib Shack would become shanes-rib-shack.

Here's what I have so far. The lowercase part was easy, but the replace doesn't seem to be working at all, and I have no idea to remove the punctuation:

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

document.addEventListener('DOMContentLoaded', function() {
        function generateSlug(value) {
            return value
                .toString()
                .toLowerCase()
                .replace(/\s+/g, '-')           // Replace spaces with -
                .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
        }

        const restaurantNameInput = document.getElementById('restaurant_name');
        const subdomainInput = document.getElementById('subdomain');

        if (restaurantNameInput && subdomainInput) {
            restaurantNameInput.addEventListener('input', function() {
                let restaurantName = this.value;
                let slug = generateSlug(restaurantName);
                subdomainInput.value = slug;
            });
        } else {
            console.error('Restaurant name input or subdomain input not found.');
        }
    });

One day I woke up and I wanted to write of a perfect slugify function in javascript that will provide the same result as Wordpress sanitize title (what a terrible name, sanitize title, btw), and just get on with my life.

I've snooped around, seen a lot of solutions (which are maybe too complex for no particular reason), revised my solution that I was using for years (which was too simple and sucked big time). I've also looked into Wordpress code, no comment.

I've also found the Sal's post. His code was cool but too complex for my taste. Most importantly his post contained one very important thing, a table of data that he used for testing.

So I sat down and came up with this:

function slugify(str) {
  str = str.trim().toLowerCase()
  // Remove accents
  str = str.normalize('NFD').replace(/[\u0300-\u036f]/g, '').replace(/\œ/g, "oe").replace(/\æ/g, "ae").normalize('NFC')
  // Strip html tags
  str = str.replace(/<[^>]*>/g, '')
  return str.replace(/\s+|\.+|\/+|\\+|—+|–+/g, '-').replace(/[^\w0-9\-]+/g, '').replace(/-{2,}/g, '-').replace(/^-|-$/g, '')
}

Validating it through Jest with a data set I've extracted from Sal's post.

You can see it in function in the fiddle https://jsfiddle.net/stamat/vq14dL5z/

You can find this function as a part of my small ESM library https://github.com/stamat/book-of-spells in form of a NPM/YARN package book-of-spells. It's a library of my JS snippets, please do contribute if you see fit and feel free to use any part of it!

Thanks to Sal Ferrarello and all of you for providing little clues and helping me come up with my solution. Thanks everyone!

I have no idea where the 'slug' term came from, but here we go:

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

console.log(convertToSlug("hello world!"));
console.log(convertToSlug("hello - world!"));

The first replace method will change spaces to hyphens, second, replace removes anything not alphanumeric, underscore, or hyphen.

If you don't want things "like - this" turning into "like---this" then you can instead use this one:

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

console.log(convertToSlug("hello world!"));
console.log(convertToSlug("hello - world!"));

That will remove hyphens (but no spaces) on the first replace, and in the second replace it will condense consecutive spaces into a single hyphen.

So "like - this" comes out as "like-this".

All you needed was a plus :)

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

Well, after reading the answers, I came up with this one.

const generateSlug = (text) => text.toLowerCase()
                                   .trim()
                                   .replace(/[^\w- ]+/g, '')
                                   .replace(/ /g, '-')
                                   .replace(/[-]+/g, '-');

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

This code is working

First of all, regular expressions should not have surrounding quotes, so '/\s/g' should be /\s/g

In order to replace all non-alphanumerical characters with dashes, this should work (using your example code):

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

That should do the trick...

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,'');
}

I filtered it twice because more - could be put in because of some unwanted characters

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

this works for me fine.

Note: if you don't care about an argument against the accepted answer and are just looking for an answer, then skip next section, you'll find my proposed answer at the end

the accepted answer has a few issues (in my opinion):

1) as for the first function snippet:

no regard for multiple consecutive whitespaces

input: is it a good slug

received: ---is---it---a---good---slug---

expected: is-it-a-good-slug

no regard for multiple consecutive dashes

input: -----is-----it-----a-----good-----slug-----

received: -----is-----it-----a-----good-----slug-----

expected: is-it-a-good-slug

please note that this implementation doesn't handle outer dashes (or whitespaces for that matter) whether they are multiple consecutive ones or singular characters which (as far as I understand slugs, and their usage) is not valid

2) as for the second function snippet:

it takes care of the multiple consecutive whitespaces by converting them to single - but that's not enough as outer (at the start and end of the string) whitespaces are handled the same, so is it a good slug would return -is-it-a-good-slug-

it also removes dashes altogether from the input which converts something like --is--it--a--good--slug--' to isitagoodslug , the snippet in the comment by @ryan-allen takes care of that, leaving the outer dashes issue unsolved though

now I know that there is no standard definition for slugs, and the accepted answer may get the job (that the user who posted the question was looking for) done, but this is the most popular SO question about slugs in JS, so those issues had to be pointed out, also (regarding getting the job done!) imagine typing this abomination of a URL (www.blog.com/posts/-----how-----to-----slugify-----a-----string-----) or even just be redirected to it instead of something like (www.blog.com/posts/how-to-slugify-a-string), I know this is an extreme case but hey that's what tests are for.

a better solution, in my opinion, would be as follows:

const slugify = str =>
  str
  .trim()                      // remove whitespaces at the start and end of string
  .toLowerCase()              
  .replace(/^-+/g, "")         // remove one or more dash at the start of the string
  .replace(/[^\w-]+/g, "-")    // convert any on-alphanumeric character to a dash
  .replace(/-+/g, "-")         // convert consecutive dashes to singuar one
  .replace(/-+$/g, "");        // remove one or more dash at the end of the string

now there is probably a RegExp ninja out there that can convert this into a one-liner expression, I'm not an expert in RegExp and I'm not saying that this is the best or most compact solution or the one with the best performance but hopefully it can get the job done.

Combining a variety of elements from the answers here with normalize provides good coverage. Keep the order of operations to incrementally clean the 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
}

normlize('NFD') breaks accented characters into their components, which are basic letters plus diacritics (the accent part). replace(/[\u0300-\u036f]/g, "") purges all the diacritics, leaving the basic letters by themselves. The rest is explained with inline comments.

For people already using lodash

Most of these example are really good and cover a lot of cases. But if you 'know' that you only have English text, here's my version that's super easy to read :)

_.words(_.toLower(text)).join('-')

More powerful slug generation method on pure JavaScript. It's basically support transliteration for all Cyrillic characters and many Umlauts (German, Danish, France, Turkish, Ukrainian and etc.) but can be easily extended.

function makeSlug(str)
{
  var from="а б в г д е ё ж з и й к л м н о п р с т у ф х ц ч ш щ ъ ы ь э ю я ā ą ä á à â å č ć ē ę ě é è ê æ ģ ğ ö ó ø ǿ ô ő ḿ ʼn ń ṕ ŕ ş ü ß ř ł đ þ ĥ ḧ ī ï í î ĵ ķ ł ņ ń ň ř š ś ť ů ú û ứ ù ü ű ū ý ÿ ž ź ż ç є ґ".split(' ');
  var to=  "a b v g d e e zh z i y k l m n o p r s t u f h ts ch sh shch # y # e yu ya a a ae a a a a c c e e e e e e e g g oe o o o o o m n n p r s ue ss r l d th h h i i i i j k l n n n r s s t u u u u u u u u y y z z z c ye g".split(' ');
	
  str = str.toLowerCase();
  
  // remove simple HTML tags
  str = str.replace(/(<[a-z0-9\-]{1,15}[\s]*>)/gi, '');
  str = str.replace(/(<\/[a-z0-9\-]{1,15}[\s]*>)/gi, '');
  str = str.replace(/(<[a-z0-9\-]{1,15}[\s]*\/>)/gi, '');
  
  str = str.replace(/^\s+|\s+$/gm,''); // trim spaces
  
  for(i=0; i<from.length; ++i)
    str = str.split(from[i]).join(to[i]);
  
  // Replace different kind of spaces with dashes
  var spaces = [/(&nbsp;|&#160;|&#32;)/gi, /(&mdash;|&ndash;|&#8209;)/gi,
     /[(_|=|\\|\,|\.|!)]+/gi, /\s/gi];

  for(i=0; i<from.length; ++i)
  	str = str.replace(spaces[i], '-');
  str = str.replace(/-{2,}/g, "-");

  // remove special chars like &amp;
  str = str.replace(/&[a-z]{2,7};/gi, '');
  str = str.replace(/&#[0-9]{1,6};/gi, '');
  str = str.replace(/&#x[0-9a-f]{1,6};/gi, '');
  
  str = str.replace(/[^a-z0-9\-]+/gmi, ""); // remove all other stuff
  str = str.replace(/^\-+|\-+$/gm,''); // trim edges
  
  return str;
};


document.getElementsByTagName('pre')[0].innerHTML = makeSlug(" <br/> &#x202A;Про&amp;вер<strong>ка_тран</strong>с…литеърьации\rюга\nи&ndash;южного&nbsp;округа\t \nс\tёжикам&#180;и&nbsp;со\\всеми&ndash;друзьями\tтоже.Danke schön!ich heiße=КáÞÿá-Skånske,København çağatay rí gé tőr zöldülésetekről - .

Yet another one. Short and keeps special characters:

imaginação é mato => imaginacao-e-mato

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
}

I found a good and complete solution for English 

function slugify(string) {
  return string
    .toString()
    .trim()
    .toLowerCase()
    .replace(/\s+/g, "-")
    .replace(/[^\w\-]+/g, "")
    .replace(/\-\-+/g, "-")
    .replace(/^-+/, "")
    .replace(/-+$/, "");
}

Some examples of it in use:

slugify(12345);
// "12345"

slugify("  string with leading   and   trailing whitespace    ");
// "string-with-leading-and-trailing-whitespace"

slugify("mIxEd CaSe TiTlE");
// "mixed-case-title"

slugify("string with - existing hyphens -- ");
// "string-with-existing-hyphens"

slugify("string with Special™ characters");
// "string-with-special-characters"

You may want to take a look at the speakingURL plugin and then you just could:

    $("#Restaurant_Name").on("keyup", function () {
        var slug = getSlug($("#Restaurant_Name").val());
        $("#Restaurant_Slug").val(slug);
    });

The accepted answer didn't meet my needs (it allows underscores, doesn't handle dashes at the beginning and end, etc.), and the other answers had other issues that didn't suit my use case, so here's the slugify function I came up with:

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.
}

This will turn ' foo!!!BAR_-_-_baz-' (note the space at the beginning) into foo-bar-baz.

Take a look at this slug function to sanitize URLs, developed by Sean Murphy at https://gist.github.com/sgmurphy/3095196

/**
 * Create a web friendly URL slug from a string.
 *
 * Requires XRegExp (http://xregexp.com) with unicode add-ons for UTF-8 support.
 *
 * Although supported, transliteration is discouraged because
 *     1) most web browsers support UTF-8 characters in URLs
 *     2) transliteration causes a loss of information

function slugify(text){
  return text.toString().toLowerCase()
    .replace(/\s+/g, '-')           // Replace spaces with -
    .replace(/[^\u0100-\uFFFF\w\-]/g,'-') // Remove all non-word chars ( fix for UTF-8 chars )
    .replace(/\-\-+/g, '-')         // Replace multiple - with single -
    .replace(/^-+/, '')             // Trim - from start of text
    .replace(/-+$/, '');            // Trim - from end of text
}

*based on https://gist.github.com/mathewbyrne/1280286

now you can transform this string:

Barack_Obama       Барак_Обама ~!@#$%^&*()+/-+?><:";'{}[]\|`

into:

barack_obama-барак_обама

applying to your code:

$("#Restaurant_Name").keyup(function(){
    var Text = $(this).val();
    Text = slugify(Text);
    $("#Restaurant_Slug").val(Text);
});

You can use your own function for this.

try it: http://jsfiddle.net/xstLr7aj/

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

  // remove accents, swap ñ for n, etc
  var from = "àáäâèéëêìíïîòóöôùúüûñç·/_,:;";
  var to   = "aaaaeeeeiiiioooouuuunc------";
  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;
}
$(document).ready(function() {
    $('#test').submit(function(){
        var val = string_to_slug($('#t').val());
        alert(val);
        return false;
    });
});

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.

        $('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;
    };

This helped me with the same problem !
