Update isActive logic to always checking equality

[onevcat]

Current isActive checking will fail when a path is prefixed by another. It causes a problem when showing active indicator in the side bar.

eg:

Say we have two pages under api folder, which are uniwebview.md and uniwebviewmessage.md. When accessing api/uniwebviewmessage.html, the result when determining side bar active state for uniwebview page is:

routePath: "/api/uniwebviewmessage"
pagePath: "/api/uniwebview"

This leads to both uniwebviewmessage and uniwebview be rendered as actived, which is not correct:

By changing it to ===, it goes fine. However, I am not sure whether there would be a regression on this change or not, since there seems like lack of tests for this project.

Not so sure why originally it checks equality only when either of them ends with / and check prefix otherwise. But your code looks alright to me, I have tested with my own site and it works ok.

Thanks, originally this function was used for isActive check for the header nav links as well, so it has as some left-over logic 😅
