// About: Support and Testing
// 
// Information about what version or versions of jQuery this plugin has been
// tested with, what browsers it has been tested in, and where the unit tests
// reside (so you can test it yourself).
// 
// jQuery Versions - 1.3.2, 1.4.1, 1.4.2
// Browsers Tested - Internet Explorer 6-8, Firefox 2-3.7, Safari 3-4,
//                   Chrome 4-5, Opera 9.6-10.1.
// Unit Tests      - http://benalman.com/code/projects/jquery-bbq/unit/
// 
// About: Release History
// 
// 1.2.1 - (2/17/2010) Actually fixed the stale window.location Safari bug from
//         <jQuery hashchange event> in BBQ, which was the main reason for the
//         previous release!
// 1.2   - (2/16/2010) Integrated <jQuery hashchange event> v1.2, which fixes a
//         Safari bug, the event can now be bound before DOM ready, and IE6/7
//         page should no longer scroll when the event is first bound. Also
//         added the <jQuery.param.fragment.noEscape> method, and reworked the
//         <hashchange event (BBQ)> internal "add" method to be compatible with
//         changes made to the jQuery 1.4.2 special events API.
// 1.1.1 - (1/22/2010) Integrated <jQuery hashchange event> v1.1, which fixes an
//         obscure IE8 EmulateIE7 meta tag compatibility mode bug.
// 1.1   - (1/9/2010) Broke out the jQuery BBQ event.special <hashchange event>
//         functionality into a separate plugin for users who want just the
//         basic event & back button support, without all the extra awesomeness
//         that BBQ provides. This plugin will be included as part of jQuery BBQ,
//         but also be available separately. See <jQuery hashchange event>
//         plugin for more information. Also added the <jQuery.bbq.removeState>
//         method and added additional <jQuery.deparam> examples.
// 1.0.3 - (12/2/2009) Fixed an issue in IE 6 where location.search and
//         location.hash would report incorrectly if the hash contained the ?
//         character. Also <jQuery.param.querystring> and <jQuery.param.fragment>
//         will no longer parse params out of a URL that doesn't contain ? or #,
//         respectively.
// 1.0.2 - (10/10/2009) Fixed an issue in IE 6/7 where the hidden IFRAME caused
//         a "This page contains both secure and nonsecure items." warning when
//         used on an https:// page.
// 1.0.1 - (10/7/2009) Fixed an issue in IE 8. Since both "IE7" and "IE8
//         Compatibility View" modes erroneously report that the browser
//         supports the native window.onhashchange event, a slightly more
//         robust test needed to be added.

// 
// About: Support and Testing
// 
// Information about what version or versions of jQuery this plugin has been
// tested with, what browsers it has been tested in, and where the unit tests
// reside (so you can test it yourself).
// 
// jQuery Versions - 1.3.2, 1.4.1, 1.4.2
// Browsers Tested - Internet Explorer 6-8, Firefox 2-3.7, Safari 3-4, Chrome, Opera 9.6-10.1.
// Unit Tests      - http://benalman.com/code/projects/jquery-hashchange/unit/
// 
// About: Known issues
// 
// While this jQuery hashchange event implementation is quite stable and robust,
// there are a few unfortunate browser bugs surrounding expected hashchange
// event-based behaviors, independent of any JavaScript window.onhashchange
// abstraction. See the following examples for more information:
// 
// Chrome: Back Button - http://benalman.com/code/projects/jquery-hashchange/examples/bug-chrome-back-button/
// Firefox: Remote XMLHttpRequest - http://benalman.com/code/projects/jquery-hashchange/examples/bug-firefox-remote-xhr/
// WebKit: Back Button in an Iframe - http://benalman.com/code/projects/jquery-hashchange/examples/bug-webkit-hash-iframe/
// Safari: Back Button from a different domain - http://benalman.com/code/projects/jquery-hashchange/examples/bug-safari-back-from-diff-domain/
// 
// About: Release History
// 
// 1.2   - (2/11/2010) Fixed a bug where coming back to a page using this plugin
//         from a page on another domain would cause an error in Safari 4. Also,
//         IE6/7 Iframe is now inserted after the body (this actually works),
//         which prevents the page from scrolling when the event is first bound.
//         Event can also now be bound before DOM ready, but it won't be usable
//         before then in IE6/7.
// 1.1   - (1/21/2010) Incorporated document.documentMode test to fix IE8 bug
//         where browser version is incorrectly reported as 8.0, despite
//         inclusion of the X-UA-Compatible IE=EmulateIE7 meta tag.
// 1.0   - (1/9/2010) Initial Release. Broke out the jQuery BBQ event.special
//         window.onhashchange functionality into a separate plugin for users
//         who want just the basic event & back button support, without all the
//         extra awesomeness that BBQ provides. This plugin will be included as
//         part of jQuery BBQ, but also be available separately.

(function ($, window, undefined) {
    '$:nomunge'; // Used by YUI compressor.

    // Method / object references.
    var fake_onhashchange,
    jq_event_special = $.event.special,

    // Reused strings.
    str_location = 'location',
    str_hashchange = 'hashchange',
    str_href = 'href',

    // IE6/7 specifically need some special love when it comes to back-button
    // support, so let's do a little browser sniffing..
    browser = $.browser,
    mode = document.documentMode,
    is_old_ie = browser.msie && (mode === undefined || mode < 8),

    // Does the browser support window.onhashchange? Test for IE version, since
    // IE8 incorrectly reports this when in "IE7" or "IE8 Compatibility View"!
    supports_onhashchange = 'on' + str_hashchange in window && !is_old_ie;

    // Get location.hash (or what you'd expect location.hash to be) sans any
    // leading #. Thanks for making this necessary, Firefox!
    function get_fragment(url) {
        url = url || window[str_location][str_href];
        return url.replace(/^[^#]*#?(.*)$/, '$1');
    };

    // Property: jQuery.hashchangeDelay
    // 
    // The numeric interval (in milliseconds) at which the <hashchange event>
    // polling loop executes. Defaults to 100.

    $[str_hashchange + 'Delay'] = 100;

    // Event: hashchange event
    // 
    // Fired when location.hash changes. In browsers that support it, the native
    // window.onhashchange event is used (IE8, FF3.6), otherwise a polling loop is
    // initialized, running every <jQuery.hashchangeDelay> milliseconds to see if
    // the hash has changed. In IE 6 and 7, a hidden Iframe is created to allow
    // the back button and hash-based history to work.
    // 
    // Usage:
    // 
    // > $(window).bind( 'hashchange', function(e) {
    // >   var hash = location.hash;
    // >   ...
    // > });
    // 
    // Additional Notes:
    // 
    // * The polling loop and Iframe are not created until at least one callback
    //   is actually bound to 'hashchange'.
    // * If you need the bound callback(s) to execute immediately, in cases where
    //   the page 'state' exists on page load (via bookmark or page refresh, for
    //   example) use $(window).trigger( 'hashchange' );
    // * The event can be bound before DOM ready, but since it won't be usable
    //   before then in IE6/7 (due to the necessary Iframe), recommended usage is
    //   to bind it inside a $(document).ready() callback.
