This project is not maintained!

The code is here if you want it, but this is not maintained. If you'd like to take over, go ahead and send a pull request. Browsers are modern enough, just ditch the last few that don't support the History API.

history.js

history.js provides an implementation of the HTML5 history API: history.pushState and history.replaceState functions, as well as the window.onpopstate event.

Browsers that already support his event (Chrome & Safari, Firefox 4+) use native implementations, which are able to change the page URL without refreshing the page. Older browsers use location.hash in order to mimic the official behavior.

Limitations

• Does not support multiple handlers for the onpopstate event

Installation

Include the script file in your HTML file:

<!-- Include JSON if you want to support older browsers -->
<script type="text/javascript" src="json2.js"></script>
<script type="text/javascript" src="history-min.js"></script>

Usage

Same as the official HTML5 API:

// Switch to the item
window.history.pushState({ id: 35 }, 'Viewing item #35', '/item/35'});

window.onpopstate = function (e) {
  var id = e.state.id;
  load_item(id);
};

Any use allowed in the standard but not supported by this API is considered a bug.
