Detect current page with JavaScript

Question

I'm wondering if Javascript can detect what page the user is on. Say for example that the user is on a "About" or "Contact" page, can JavaScript check if the pathway is "/About" or "/Contact" and then take action accordingly ? How would that code look like? I appreciate if anyone could give me a code sample

`if(location.href=='/contacts')document.body.innerHTML="";` check the location, set the body html to empty string. — nicael, Nov 19 '15 at 13:51
When you searched on Google for "javascript get current URL", you didn't find *anything*? — David, Nov 19 '15 at 13:54
Look, I [googled your title](https://www.google.com/search?q=Detect%20current%20page%20with%20JavaScript) and came up with 9,640,000 results, and everything on the first page is exactly what people here are telling you to do... — Howard Renollet, Nov 19 '15 at 14:00
So you people who are telling OP to search, do you not know how to close questions as a duplicate? You people sound very rude to a new user here. — epascarello, Nov 19 '15 at 14:02
@epascarello, done. But pray tell, why did you insist on answering this instead of closing as a duplicate? Surely a user with your reputation can find one quickly enough. — Frédéric Hamidi, Nov 19 '15 at 17:41

For example, you can get the URL by doing this:

window.location.href

If you want to know what age they are on, it really depends on the url structure. But you will get the information with window.location.pathname

var pathname = window.location.pathname;
switch(pathname) {
   case "/home" :
       console.log("home");
       break;
   case "/game" :
       console.log("game");
       break;
}
