Javascript - get current page URL without pagination numbers

Say I have a URL for an article:

http://domain.com/blog/articles/title-here/

And it has about 5 pages, so as you go through each page, you get:

http://domain.com/blog/articles/title-here/ OR http://domain.com/blog/articles/title-here/1

http://domain.com/blog/articles/title-here/2

http://domain.com/blog/articles/title-here/3

http://domain.com/bl开发者_JAVA技巧og/articles/title-here/4

http://domain.com/blog/articles/title-here/5

I know that the following code will get the full current URL (aka including the page #):

var u = window.location.href;

But is there a way to limit it so that the page # is NOT a part of the variable "u"?

Perhaps there's a regex or something I should add in there..? (I'm fairly new to javascript, so not sure how to apply this?)

---

var u = window.location.href.match(/.*[/][^\d]*/)[0]

Would that work for you?

Edit

I changed it... again :P

NOTE: Regex is a more complicated version of Joseph's and still suffers from the same bug. Will undelete when I fix it.

Joseph's answer is good, but it has a minor bug: it will drop the last part of the URL if you have an URL like:

http://domain.com/blog/articles/title-here

You can use this instead:

var u = window.location.href.match(/(.*)(\/\d*)/)[1]

How the regex works:

/          # delimiter
(.*?)      # match anything and put in capture group 1
(\/        # match the forward slash
 \d*)      # match zero or more digits
/          # delimiter

---

var l = window.location;
l.href.replace(l.pathname, l.pathname.split(/\/[0-9]+$/)[0]);

try it in the console at this URL

---

Regex would do it. But in this case, you could just turn it into an array, strip of the end item, and re-serialize it.

var a = 'http://domain.com/blog/articles/title-here/2'.split('/');
a.splice(-1, 1);
a.join('/');
