Javascript Browser History length Property

Introduction

The length property returns the number of URLs in the history list of the current browser window.

Get the number of URLs in the history list: 

var x = history.length;

This example is opened in a new frame and will be treated as a new "session".

View in separate window 

<!DOCTYPE html>
<html>
<body>

<p>Number of URLs in history list:</p>

<p id="demo"></p>
<script>
var x = history.length;//from   w  ww. j  a  v a2 s .  c om
document.getElementById("demo").innerHTML = x;
</script>

</body>
</html>

The property returns at least 1, since the list has the currently loaded page.

Maximum length is 50.

This property is read-only.
