I have my page where i have added back / next button in my page, to navigate back next, same as browser back next button, I have seen in browser if there no history of page, than browser back/next button is disabled, if forward history is not there than next button is disabled, vice versa with back button, can i do same with my back next button used in my page, i am using same functionality as browser. Note i have mutliple pages in my site. so it should not stop other navigation.
