jQuery history event v0.4
Copyright (c) 2014 Tom Rodenberg <tarodenberg gmail com>
jQuery history event is released under two licenses: new BSD, and MIT. You may pick the
license that best suits your development needs.

Adds a history event to jQuery. Allows dynamic pages to create page states and easily recall them when user navigation occurs (such as the back button).

$(function() {
    $('#status').history(function(e, currentHash, previousHash) {
        $(this).html('User navigated to: ' + currentHash);
    });
    $('#status').historyadd(function(e, currentHash, previousHash) {
        $(this).html('Navigation added: ' + currentHash);
    });

    $(window).history(function(e, hash) {
        //myCustomLoadFunction(hash);
    });

    $('#button').click(function() {
        $.history.add('item123');
    });

    $('#status').html('The initial location is: ' + $.history.getCurrent());
});

Need data storage?

$(function(){
    var textboxData = {};
    $('#textbox').historyadd(function(e, currentHash, previousHash) {
        textboxData[previousHash] = $(this).val();
    });

    $('#textbox').history(function(e, currentHash, previousHash) {
        $(this).val(textboxData[currentHash] || '');
    });
});
