Following problem: I would like to not have to copy my navigation bar over every site. So I wrote it in an extra Document and included it with php. The site ur on has a special class to show its active now that where I'm stuck at. I tried following statement just to see if my idea works

<script> if(document.getElementById("test").href == window.location.pathname){window.alert("wow");}

Spoiler alert it does not:(

I know that the pathname is the same as href(tried it) but I can't get the href like that. Does anybody know how to do that? Sorry for my English

Thanks a lot for helping

PS: I'm just getting into js I usually work with other languages but wanted to get into website design.
