How to get the previous URL in JavaScript?

Question

Is there any way to get the previous URL in JavaScript? Something like this:

alert(\"previous url is: \" + window.history.previous.href);

Answer 1

If you are writing a web app or single page application (SPA) where routing takes place in the app/browser rather than a round-trip to the server, you can do the following:

window.history.pushState({ prevUrl: window.location.href }, null, "/new/path/in/your/app")

Then, in your new route, you can do the following to retrieve the previous URL:

window.history.state.prevUrl // your previous url
