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. +// 1.0 - (10/2/2009) Initial release + +(function($,window){ + '$:nomunge'; // Used by YUI compressor. + + // Some convenient shortcuts. + var undefined, + aps = Array.prototype.slice, + decode = decodeURIComponent, + + // Method / object references. + jq_param = $.param, + jq_param_sorted, + jq_param_fragment, + jq_deparam, + jq_deparam_fragment, + jq_bbq = $.bbq = $.bbq || {}, + jq_bbq_pushState, + jq_bbq_getState, + jq_elemUrlAttr, + special = $.event.special, + + // Reused strings. + str_hashchange = 'hashchange', + str_querystring = 'querystring', + str_fragment = 'fragment', + str_elemUrlAttr = 'elemUrlAttr', + str_href = 'href', + str_src = 'src', + + // Reused RegExp. + re_params_querystring = /^.*\?|#.*$/g, + re_params_fragment, + re_fragment, + re_no_escape, + + ajax_crawlable, + fragment_prefix, + + // Used by jQuery.elemUrlAttr. + elemUrlAttr_cache = {}; + + // A few commonly used bits, broken out to help reduce minified file size. + + function is_string( arg ) { + return typeof arg === 'string'; + }; + + // Why write the same function twice?

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.
