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

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,'')        ;}

First replace 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,'-')        ;}

That will remove hyphens (but not 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".

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;};

and try

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

EDIT:extended for more language specific chars:

var from = "ÁÄÂÀÃÅČÇĆĎÉĚËÈÊẼĔȆĞÍÌÎÏİŇÑÓÖÒÔÕØŘŔŠŞŤÚŮÜÙÛÝŸŽáäâàãåčçćďéěëèêẽĕȇğíìîïıňñóöòôõøðřŕšşťúůüùûýÿžþÞĐđßÆa·/_,:;";var to   = "AAAAAACCCDEEEEEEEEGIIIIINNOOOOOORRSSTUUUUUYYZaaaaaacccdeeeeeeeegiiiiinnooooooorrsstuuuuuyyzbBDdBAa------";

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...
