![]() The browsers history object contains history of all the web pages or URLs the user has been visited. Output: And once we click the above Forward Method button, the output is Output: once we click the above Back Method button, the output is Here again have two html pages h1.html and h2.html, where h1.html contain the link for h2.html and history object forward() method, the h2.html contain same as above. ![]() The history.forward() method used to load the forward page from history URLs. Next we rewrite the above html code to see working of history.forward() method. Click the below button to go back prevous page visited by the user by using go method. ![]() Here we will create again two html pages h1.html and h2.html, where h1.html will contain the link for h2.html and h2.html will contain code to call history object go(-1) method which go just one step backward. If we pass greater than 0 value to the go() method then it loads the forward page for example go(2) goes two steps in forward direction, if we pass lesser than 0 value to the go() method then it loads the backward page for example go(-1) goes one step in backward direction. Next we write the html code to understand the working of history.go(), the history.go() method used to loads the particular page(forward or the backward) from history URLs. Output: And once we click the above Back Method button, the output is Output: Once we click the above link, the output is Click the below button to go back prevous page or URLs visited by the user. So once the back method called it go to the previous URL that is h1.html, as in below code – Here we will create two html pages h1.html and h2.html, where h1.html will contain the link for h2.html and h2.html will contain code to call history object back() method. Next we write the html code to understand the working of history.back() method more clearly with the following example, the history.back() method used to load the previous page from history URLs. Output: Once we click on the Length Property button the output is Īlert( "The number of URLs in the browser history is " + ) Click the below button to see the number of URLs visited by the user. This Is An Example For History Object In JavaScript Next we write the html code to understand the working of history.back() method more clearly with the following example, the history.back() method used to load the previous page from history URLs using the button element: forward(): forward() method loads the next page which is same as clicking forward button in the browser.Įxamples to Implement JavaScript History Objectīelow are the examples mentioned: Example #1.back(): back() method loads the previous page which is same as clicking backward button in the browser.This method use as go(distance) which is same as clicking the forward or the backward button to the specified page. go(): go() method loads the specified page number in browser.Just use explicit links to pages instead of relying on browser history. So using javascript:history.back() introduces a small risk that can be exploited by phishing attacks. However, I guess some users may expect the “Go Back” link to go to the legitimate site. Also, our demo was a little contrived in that it clearly shows an error message and a “Go Back” link. ![]() ![]() I am still not certain how much this would fool people, that would not just be fooled by a normal phishing page. Now you end up on my phishing page.īy clicking a link on a trusted domain, you ended up on a phishing page. It looks legitimately to be the Bank of Egypt. I made a little proof of concept page that tries to exploit this. The 404 error page on that domain contains a link that triggers history.back(). The National Bank of Egypt is at the domain. It could succeed in tricking the user, depending on when they check the URL in the browser bar. Now, this attack scenario is a little far fetched, since the user needs to visit the attacker’s site and click a link. The user is now on the attacker’s site again, by clicking on a link in an application they trust. The attacker’s page forwards to a page on a trusted domain with a link that triggers history.back().However, that previous page may not belong to the same domain, and the user may expect links on domains to be trusted. This is functionally the same as clicking the back button in the browser: it navigates to the previous page. ![]()
