Regular expression with Variable

Question

Im trying to remove the 'page=?' (? = only numbers) from URL path with following method:

var urlslugRegex = '/^[a-z0-9-]+$/';
var url = window.location.href;
var lastpath = url.substring(url.lastIndexOf('/') + 1);
var lasturl = lastpath.replace('page=' + urlslugRegex, '');

but the regular expression not working. Any ideas?

Are you tyring to remove the *entire* querystring? If so: https://stackoverflow.com/questions/2540969/remove-querystring-from-url — Rory McCrossan, Apr 23 '18 at 13:49

var urlslugRegex = '/^[a-z0-9-]+$/';
var url = window.location.href;
var lastpath = url.substring(url.lastIndexOf('/') + 1);
var lasturl = lastpath.replace('page=' + urlslugRegex, '');

The regex which is being sent to replace() function is

page=/^[a-z0-9-]+$/

I hope, this is not what you wanted.

You can fix it by simply by

var lasturl = lastpath.replace(/^page=[a-z0-9-]+$/, '');
