How to simulate Browser back button

When someone asks how to simulate a back button, they really mean to ask how to create a link that points to the previously visited page. Most browsers tend to keep a list of which websites the user has visited and in what order they have done so.

The DOM window object provides access to the browser's history through the history object. Moving backward and forward through the user's history is done using the  back(), forward(), and go() methods of the history object.

To move backward through history, just do window.history.back(); This will act exactly like the user clicked on the Back button in their browser toolbar.

Find below a sample html code:

<html>
<head>
<script type="text/javascript">
function goBack(){
 window.history.back()
}
</script>
</head>
<body>
   <input type="button" value="Back" onclick="goBack()" />
</body>
</html>
