Is It possible to call a user defined JS function when the page refresh button is clicked? I want to call a reload function, if yes is clicked I want the user to logout. Below is my code I used. but am getting a different confirmation pop up which reloads the page. I am nor able to call my custom function. Below is my code window.onbeforeunload = function() { var r=confirm("Do you want to leave page!"); if (r) { //write redirection code sessLogOut(); } else { //do nothing } };

A good solution for you may be using this in your html: 

<body onunload="pageUnload()">

and this in JS:

function pageUnload(){
  if(confirm("Do you want to leave page!")){
     // DO SOMETHING
  } else {
     // DO NOTHING
  }
}
