Question

Trying to write a javascript bookmarklet to jump from a front end link into a CMS edit page link.

So take a url like this

http://www.example.com/events/13097/article

and make a url like this

http://www.example.com/admin/edit.php?class=events&id=13097

I think I need to use regex to grab the class and id and then wrap it into a javascript function- but I’m a absolute beginner and wondering if someone can get me started?

Answer 1

You don’t need regex, Try this:

var url = ""+window.location;
var urlparts = url.split('/');
window.location = "http://www.example.com/admin/edit.php?class="+urlparts[3]+"&id="+urlparts[4];

splits the class and the id from the URL and repeats them in the redirect.
the first line casts the window.location to a string you could also use String(window.location) to do this, but that’s more verbose.

to get the domain too, you can use:

"http://"+urlparts[2]+"/admin/edit.php?class="+urlparts[3]+"&id="+urlparts[4]

EDIT: Actually, you can get the urlparts with window.location.href.split('/') or to emulate the original code window.location.toString().split('/') other items of interest in the window.location object (examples from this post)
