Get previous page

How to get the previous page with javascript by phone?

I want to return ( window.history.back() ) only if I came from one specific html file, otherwise I want to go to another html page when I click the "Back" button. So I want to know which one is the previous page of the story.

I was looking for time to search, and I did not find an answer that suits me.

If you want something inline, you can use document.referrer to get the previous URL. But it can be unreliable for your needs. More details here , here and here

Another VERY simple option is to save the name of the current page in the session store, read it, and then decide what to do next.

 //retrieve the previous page var previouspage = window.sessionStorage.getItem("page"): // if thee is no previous page you are on the first page if (previousPage == undefined){ //do something if you want, this means it the first page the user is seeing } //get current page address var currentPage = window.location.href; //store it window.sessionStorage.setItem("page",currentPage); //check if the previous page is the one you wanted. if (previousPage == "the_page_you_wanted"){ // do something. }

LocalStorage vs SessionStorage
