Fixes #120 as well.

Hi @davist11, Is it possible for you to merge this? Thank you!

@RajeebTheGreat I think this repository is not maintained anymore, but feel free to use my fork where this issue is fixed: https://github.com/mmiszy/jQuery-One-Page-Nav

This is the entire point of the filter option

How the filter option works remains unchanged, I only fixed a bug in it. Moreover I fixed #120 and took care of the scenario where link might be external.

But what if someone is forced to use absolute URLs in their links?

[typeofweb]

I'm not sure what you mean by that? Clicking on an external link navigates to another website.

This has nothing to do with relative/absolute URLs. Absolute URLs work just fine as long as they're internal, not external.

For example, imagine your website address is http://davist11.co/. Any of the following hrefs are considered internal:

• /
• dsadsa
• /dsadsa/dsadsa
• abc/def
• http://davist11.co/
• http://davist11.co/abc
• http://davist11.co/das/das/das/

While these are considered external:

• http://google.com/
• http://facebook.com/friends/
• http://blog.davist11.com/
