I am trying to show an alert when clicking the back button in Chrome. It is working properly in Firefox, but not in Chrome. Where do I need to change the code?

jQuery(document).ready(function($) {
  history.pushState(null, document.title, location.href);
  window.addEventListener('popstate', function (event) {
    history.pushState(null, document.title, location.href); 
    alert('Back button was pressed.');
  });
});

Does Chrome give any warnings/errors related to this in the Console? – JohnPete22 Oct 29 '19 at 11:49

no not showing any warning in console – code_flow Oct 29 '19 at 12:00
What about the breakpoints you set when you are debugging? Does it hit in Chrome? – JohnPete22 Oct 29 '19 at 12:01

Yes. But it's skipping the alert section. – code_flow Oct 29 '19 at 12:06
Yes Abhishek ,I had tried this earlier and it's not working. Not even on reload. – code_flow Oct 29 '19 at 12:15
https://stackoverflow.com/questions/9611937/addeventlistener-not-triggering-when-used-in-a-chrome-extension. I Tried your method. this works in chrome when you do 1 click on the page. It may be how popstate is managed in chrome. – Abhishek Tripathi Oct 29 '19 at 12:26
Abhishek, alert pops if I first click on A-tag even if I don't click on back button. And If I click back button after once a-tag is clicked, alert is shown. This A-tag doesn't redirect to any site or anything . – code_flow Oct 29 '19 at 12:48
JohnPete22 ,It skips this part when I set breakpoints while debugging. It catches it if (a-tag) is clicked. `history.pushState(null, document.title, location.href); alert('Back button was pressed.');` – code_flow Oct 29 '19 at 13:00
