The  popstate  event only works when you push something before  So you have to do something like this   jQuery document  ready function         if  window history  amp  amp  window history pushState         window history pushState  forward   null      forward           window  on  popstate   function           alert  Back button was pressed                        For browser backward compatibility I recommend  history js

In my case I am using jQuery  load   to update DIVs in a SPA  single page  web  app       Being new to working with   window  on  hashchange       event listener   this one proved challenging and took a bit to hack on   Thanks to reading a lot of answers and trying different variations   finally figured out how to make it work in the following manner   Far as I can tell  it is looking stable so far      In summary - there is the variable globalCurrentHash that should be set each time you load a view       Then when   window  on  hashchange       event listener runs  it checks the following          If location hash has the same value  it means Going Forward   If location hash has different value  it means Going Back      I realize using global vars isn t the most elegant solution  but doing things OO in JS seems tricky to me so far   Suggestions for improvement refinement certainly appreciated    Set Up    Define a global var           var globalCurrentHash   null     When calling  load   to update the DIV  update the global var as well    function loadMenuSelection hrefVal          layout main   load nextView     globalCurrentHash   hrefVal     On page ready  set up the listener to check the global var to see if Back Button is being pressed     document  ready function        window  on  hashchange   function          console log   location hash      location hash          console log   globalCurrentHash      globalCurrentHash           if  location hash    globalCurrentHash              console log   Going fwd                   else              console log   Going Back               loadMenuSelection location hash

Hasan Badshah s answer worked for me  but the method is slated to be deprecated and may be problematic for others going forward   Following the MDN web docs on alternative methods  I landed here  PerformanceNavigationTiming type  if  performance getEntriesByType  navigation   0  type      back forward          back or forward button functionality     This doesn t directly solve for back button over the forward button  but was good enough for what I needed  In the docs they detail the available event data that may be helpful with solving your specific needs    function print nav timing data          Use getEntriesByType   to just get the  navigation  events   var perfEntries   performance getEntriesByType  navigation       for  var i 0  i  lt  perfEntries length  i          console log    Navigation entry     i             var p   perfEntries i          dom Properties     console log  DOM content loaded        p domContentLoadedEventEnd -      p domContentLoadedEventStart        console log  DOM complete       p domComplete       console log  DOM interactive       p interactive           document load and unload time     console log  document load        p loadEventEnd - p loadEventStart        console log  document unload        p unloadEventEnd -      p unloadEventStart            other properties     console log  type       p type       console log  redirectCount       p redirectCount           According to the Docs at the time of this post it is still in a working draft state and is not supported in IE or Safari  but that may change by the time it is finished   Check the Docs for updates
