Javascript Filename function / .html strip

Question

Good Morning,

I'm using a function I got from another post here:

To return the current filename of a webpage

var url=window.location.pathname;
var filename = url.replace(/^.*[\\\/]/, '');
alert(filename);

and I was curious as to whether it is possible to strip the .html from the end while still using this syntax.

Either specify the extensions you want to manage, to be more restrictive, using:

.replace(/^.*[\/](.*)[.](html|jsp|php)/, '$1');

Either be more generic, using:

.replace(/^.*[\/](.*)[.][a-zA-Z0-9]{2,5}/, '$1');

The second one will allow extensions from 2 chars (e.g. .do) to 5 chars (e.g. .xhtml), which could also contain numbers (e.g. .php3).

@user1821973 I'm not sure this regex is the cause of the IE8 issue you're meeting: it must come from somewhere else in your script. But whatever, I'm glad I could help `;)` – sp00m Dec 19 '12 at 16:19
It is possible, sorry I jumped straight to that conclusion, here let me edit: *The regex probably works in IE8 because IE8 does support regex; however, something unforseen in my script is preventing this statement from working. – Deprecated Dec 19 '12 at 16:28

I think the easiest way will be

var filename = url.replace(/^.*[\\\/]/, '').replace(".html", "");

This is the most broswer comprehensive answer of all the answers, so it is the one I'm accepting; however all of the answers are great! – Deprecated Dec 19 '12 at 16:15

You can use a capture clause in replace:

var url=window.location.pathname;
alert(url)
var filename = url.replace(/^.*[\\\/](.*).html$/, '$1');
alert(filename);
