The maximum value of 'window.history.length'

The value of window.history.length is very important in our project to detect the back button is clicked in the browser. However, I realized that window.history.length does not pass 50. How can I solve this?

Depending on whether you need it to be persistent across sessions and surviving a clean of the user information (cache, localStorage, etc.), you might want to adopt different solutions.

One of the solutions could be to do something like this:

window.onpopstate = function(event) {
  var count = parseInt(localStorage.getItem('history-changes-count'), 10);
  localStorage.setItem('history-changes-count', ++count);
};

Note that onpopstate gets invoked only after a user action. It doesn't work if you modify the history programmatically.

It is possible to detect "Back Button Clicked" via iFrames. You can find the answer at Browser Back Button Detection.
