TL;DR

The window.history API allows you to manipulate the browser's session history. You can use history.pushState() to add a new entry to the history stack, history.replaceState() to modify the current entry, and history.back(), history.forward(), and history.go() to navigate through the history. For example, history.pushState({page: 1}, "title 1", "?page=1") adds a new entry to the history.

Using the window.history API

The window.history API provides methods to interact with the browser's history stack. This can be useful for single-page applications (SPAs) where you want to manage the URL and browser history without causing a full page reload.

Methods

history.pushState()

This method adds a new entry to the history stack.

history.pushState({ page: 1 }, 'title 1', '?page=1');
  • The first parameter is a state object associated with the new history entry.
  • The second parameter is the title of the new history entry (currently ignored by most browsers).
  • The third parameter is the URL to be displayed in the address bar.

history.replaceState()

This method modifies the current history entry.

history.replaceState({ page: 2 }, 'title 2', '?page=2');
  • The parameters are the same as pushState(), but this method replaces the current entry instead of adding a new one.

history.back()

This method moves the user back one entry in the history stack, similar to clicking the browser's back button.

history.back();

history.forward()

This method moves the user forward one entry in the history stack, similar to clicking the browser's forward button.

history.forward();

history.go()

This method moves the user a specified number of entries in the history stack.

// Move back one entry
history.go(-1);


// Move forward one entry
history.go(1);


// Reload the current page
history.go(0);

Example

Here's a simple example demonstrating the use of pushState and replaceState:

<!doctype html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <title>History API Example</title>
  </head>
  <body>
    <button id="pushStateBtn">Push State</button>
    <button id="replaceStateBtn">Replace State</button>
    <button id="backBtn">Back</button>
    <button id="forwardBtn">Forward</button>


    <script>
      document.getElementById('pushStateBtn').addEventListener('click', () => {
        history.pushState({ page: 1 }, 'title 1', '?page=1');
      });


      document
        .getElementById('replaceStateBtn')
        .addEventListener('click', () => {
          history.replaceState({ page: 2 }, 'title 2', '?page=2');
        });


      document.getElementById('backBtn').addEventListener('click', () => {
        history.back();
      });


      document.getElementById('forwardBtn').addEventListener('click', () => {
        history.forward();
      });
    </script>
  </body>
</html>
