I modified Sanoj Dushmantha s answer to use sessionStorage instead of localStorage  However  despite the documentation  browsers will still store this data even after the browser is closed  To fix this issue  I am removing the scroll position after it is reset   lt script gt      document addEventListener  quot DOMContentLoaded quot   function  event            var scrollpos   sessionStorage getItem  scrollpos            if  scrollpos                window scrollTo 0  scrollpos               sessionStorage removeItem  scrollpos                           window addEventListener  quot beforeunload quot   function  e            sessionStorage setItem  scrollpos   window scrollY            lt  script gt

Thanks Sanoj  that worked for me  However iOS does not support  onbeforeunload  on iPhone  Workaround for me was to set localStorage with js    lt button onclick  myFunction    gt Click me lt  button gt    lt script gt  document addEventListener  DOMContentLoaded   function event                 var scrollpos   localStorage getItem  scrollpos                if  scrollpos  window scrollTo 0  scrollpos               function myFunction       localStorage setItem  scrollpos   window scrollY     location reload        lt  script gt

This might be useful for refreshing also  But if you want to keep track of position on the page before you click on a same position   The following code will help   Also added a data-confirm for prompting the user if they really want to do that    Note  I m using jQuery and js-cookie js to store cookie info     document  ready function            make all links with data-confirm prompt the user first          data-confirm    on  click   function  e            e preventDefault            var msg     this  data  confirm            if confirm msg   true                var url   this href              if url length gt 0  window location   url              return true                    return false                  on certain links save the scroll postion          saveScrollPostion   on  click   function  e            e preventDefault            var currentYOffset   window pageYOffset      save current page postion          Cookies set  jumpToScrollPostion   currentYOffset           if    this  attr  data-confirm          if there is no data-confirm on this link then trigger the click  else we have issues              var url   this href              window location   url                  this  trigger  click        continue with click event                            check if we should jump to postion      if Cookies get  jumpToScrollPostion        undefined             var jumpTo   Cookies get  jumpToScrollPostion            window scrollTo 0  jumpTo           Cookies remove  jumpToScrollPostion        and delete cookie so we don t jump again              A example of using it like this    lt a href  gotopage html  class  saveScrollPostion  data-confirm  Are you sure   gt Goto what the heck lt  a gt

UPDATE  You can use document location reload true  as mentioned below instead of the forced trick below   Replace your HTML with this    lt  DOCTYPE html gt   lt html gt       lt head gt           lt style type  text css  gt              body                    background-image  url     Images Black-BackGround gif                    background-repeat  repeat                            body td                  font-Family  Arial                  font-size  12px                              Nav a                    position relative                   display block                   text-decoration  none                   color black                          lt  style gt           lt script type  text javascript  gt              function refreshPage                      var page y   document getElementsByTagName  body   0  scrollTop                  window location href   window location href split      0      page y     page y                            window onload   function                      setTimeout refreshPage  35000                   if   window location href indexOf  page y      -1                         var match   window location href split      1  split   amp    0  split                           document getElementsByTagName  body   0  scrollTop   match 1                                            lt  script gt       lt  head gt       lt body gt  lt  -- BODY CONTENT HERE -- gt  lt  body gt   lt  html gt

If you don t want to use local storage then you could attach the y position of the page to the url and grab it with js on load and set the page offset to the get param you passed in  i e      code to refresh the page var page y      document   scrollTop    window location href   window location href     page y     page y      code to handle setting page offset on load   function         if   window location href indexOf   page y       -1               gets the number from end of url         var match   window location href split      1  match    d               var page y   match 0              sets the page offset              html  body    scrollTop  page y

this will do the magic       lt script gt          document addEventListener  DOMContentLoaded   function event                 var scrollpos   localStorage getItem  scrollpos                if  scrollpos  window scrollTo 0  scrollpos                        window onbeforeunload   function e                localStorage setItem  scrollpos   window scrollY                   lt  script gt

document location reload   stores the position  see in the docs   Add additional true parameter to force reload  but without restoring the position    document location reload true    MDN docs      The forcedReload flag changes how some browsers handle the user s scroll position  Usually reload   restores the scroll position afterward  but forced mode can scroll back to the top of the page  as if window scrollY     0
