//
// Because the target of the touch event that triggered the vclick
// can be different from the target of the click event synthesized
// by the browser. The target of a mouse/click event that is syntehsized
// from a touch event seems to be implementation specific. For example,
// some browsers will fire mouse/click events for a link that is near
// a touch event, even though the target of the touchstart/touchend event
// says the user touched outside the link. Also, it seems that with most
// browsers, the target of the mouse/click event is not calculated until the
// time it is dispatched, so if you replace an element that you touched
// with another element, the target of the mouse/click will be the new
// element underneath that point.
//
// Aside from proximity, we also check to see if the target and any
// of its ancestors were the ones that blocked a click. This is necessary
// because of the strange mouse/click target calculation done in the
// Android 2.1 browser, where if you click on an element, and there is a
// mouse/click handler on one of its ancestors, the target will be the
// innermost child of the touched element, even if that child is no where
// near the point of touch.

//
// 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 - 1.2.6, 1.3.2, 1.4.1, 1.4.2
// Browsers Tested - Internet Explorer 6-8, Firefox 2-4, Chrome 5-6, Safari 3.2-5,
// Opera 9.6-10.60, iPhone 3.1, Android 1.6-2.2, BlackBerry 4.6-5.
// 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/
//
// Also note that should a browser natively support the window.onhashchange
// event, but not report that it does, the fallback polling loop will be used.
//
// About: Release History
//
// 1.3 - (7/21/2010) Reorganized IE6/7 Iframe code to make it more
// "removable" for mobile-only development. Added IE6/7 document.title
// support. Attempted to make Iframe as hidden as possible by using
// techniques from http://www.paciellogroup.com/blog/?p=604. Added
// support for the "shortcut" format $(window).hashchange( fn ) and
// $(window).hashchange() like jQuery provides for built-in events.
// Renamed jQuery.hashchangeDelay to <jQuery.fn.hashchange.delay> and
// lowered its default value to 50. Added <jQuery.fn.hashchange.domain>
// and <jQuery.fn.hashchange.src> properties plus document-domain.html
// file to address access denied issues when setting document.domain in
// IE6/7.
// 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.

// Reused string.

// Method / object references.
doc = document,
fake_onhashchange,
special = $.event.special,

// IE7 compatibility mode reports true for 'onhashchange' in window, even
// though the event isn't supported, so also test document.documentMode.

// leading #. Thanks for making this necessary, Firefox!
function get_fragment( url ) {

};
// Method: jQuery.fn.hashchange
//
// Bind a handler to the window.onhashchange event or trigger all bound
// window.onhashchange event handlers. This behavior is consistent with
// jQuery's built-in event handlers.
//
// Usage:
//
// > jQuery(window).hashchange( [ handler ] );
//
// Arguments:
//
// handler - (Function) Optional handler to be bound to the hashchange
// event. This is a "shortcut" for the more verbose form:
// jQuery(window).bind( 'hashchange', handler ). If handler is omitted,
// all bound window.onhashchange event handlers will be triggered. This
// is a shortcut for the more verbose
// jQuery(window).trigger( 'hashchange' ). These forms are described in
// the <hashchange event> section.
//
// Returns:
//
// (jQuery) The initial jQuery collection of elements.
// Allow the "shortcut" format $(elem).hashchange( fn ) for binding and
// $(elem).hashchange() for triggering, like jQuery does for built-in events.
$.fn[ str_hashchange ] = function( fn ) {
return fn ? this.bind( str_hashchange, fn ) : this.trigger( str_hashchange );
};
// Property: jQuery.fn.hashchange.delay
//
// The numeric interval (in milliseconds) at which the <hashchange event>
// polling loop executes. Defaults to 50.
// Property: jQuery.fn.hashchange.domain
//
// If you're setting document.domain in your JavaScript, and you want hash
// history to work in IE6/7, not only must this property be set, but you must
// also set document.domain BEFORE jQuery is loaded into the page. This
// property is only applicable if you are supporting IE6/7 (or IE8 operating
// in "IE7 compatibility" mode).
//
// In addition, the <jQuery.fn.hashchange.src> property must be set to the
// path of the included "document-domain.html" file, which can be renamed or
// modified if necessary (note that the document.domain specified must be the
// same in both your main JavaScript as well as in this file).
//
// Usage:
//
// jQuery.fn.hashchange.domain = document.domain;
// Property: jQuery.fn.hashchange.src
//
// If, for some reason, you need to specify an Iframe src file (for example,
// when setting document.domain as in <jQuery.fn.hashchange.domain>), you can
// do so using this property. Note that when using this property, history
// won't be recorded in IE6/7 until the Iframe src file loads. This property
// is only applicable if you are supporting IE6/7 (or IE8 operating in "IE7
// compatibility" mode).
//
// Usage:
//
// jQuery.fn.hashchange.src = 'path/to/file.html';
$.fn[ str_hashchange ].delay = 50;
/*
$.fn[ str_hashchange ].domain = null;
$.fn[ str_hashchange ].src = null;
*/
// Event: hashchange event
//
// Fired when location.hash changes. In browsers that support it, the native
// HTML5 window.onhashchange event is used, otherwise a polling loop is
// initialized, running every <jQuery.fn.hashchange.delay> milliseconds to
// see if the hash has changed. In IE6/7 (and IE8 operating in "IE7
// compatibility" mode), a hidden Iframe is created to allow the back button
// and hash-based history to work.
//
// Usage as described in <jQuery.fn.hashchange>:
//
// > // Bind an event handler.
// > jQuery(window).hashchange( function(e) {
// > var hash = location.hash;
// > ...
// > });
// >
// > // Manually trigger the event handler.
// > jQuery(window).hashchange();
//
// A more verbose usage that allows for event namespacing:
//
// > // Bind an event handler.
// > jQuery(window).bind( 'hashchange', function(e) {
// > var hash = location.hash;
// > ...
// > });
// >
// > // Manually trigger the event handler.
// > jQuery(window).trigger( 'hashchange' );
//
// Additional Notes:
//
// * The polling loop and Iframe are not created until at least one handler
// is actually bound to the 'hashchange' event.
// * If you need the bound handler(s) to execute immediately, in cases where
// a location.hash exists on page load, via bookmark or page refresh for
// example, use jQuery(window).hashchange() or the more verbose
// jQuery(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 DOM ready handler.
// Override existing $.event.special.hashchange methods (allowing this plugin
// to be defined after jQuery BBQ in BBQ's source code).
