Regex for removing special character from string using angular filter

Question

I want to create a angular js filter who will remove space with "-" and remove special character like ™ tm , ℠ sm, ® r,© .Below code will remove space with "-" but not remove the special characters

 (function (angular) {
    'use strict';
            angular.module('myApp')
            .filter('removespace', function () {
                return function(input) {
                    if(input) {
                        return input.replace(/\s+/g, '-');
                    }
                };
            });

})(angular);


 Output will be

    LG Stylo™ 2 PLUS >> lg-stylo-2-plus
    ZTE AVID® TRIO >> zte-avid-trio
    ZTE ZMAX® Pro >> zte-zmax-pro
    HTC Desire® 530 >> htc-desire-530
    Galaxy S® 6 edge - Gold - 32GB - Cert. Pre-Owned >> galaxy-s-6-edge-gold-32gb-cert-pre-owned

Try the following:

return input.replace(/\s+/g, '-').replace(/[^-\w]+/g, '').toLowerCase();

([^-\w] means "everything except - and a word character ([a-zA-Z0-9_]", i.e. the resulting string will only contain a-z, A-Z, 0-9, _, -.)

but it is fail if we convert "Galaxy S® 6 edge - Gold - 32GB - Cert. Pre-Owned".it should be 'galaxy-s-6-edge-gold-32gb-cert-pre-owned' instead of 'galaxy-s-6-edge---gold---32gb---cert-pre-owned'

That's slightly another requirement. Use this: input.replace(/\s+/g, '-').replace(/[^-\w]+/g, '').replace(/-{2,}/g, '-').toLowerCase()

input.toLowerCase()
    .replace(/[^\w ]+/g,'')
    .replace(/ +/g,'-');

What about replace(/\s+/g, '-') instead of replace(/ +/g,'-')?
