/* Knowmax Browser features Provides support for determining browser features. Relies on following libraries: - Prototype JavaScript library; - SWFObject; - Knowmax Measurement Utility Unit for JavaScript. version 1.3.3 - june 18 2007 - Added "k_eventid: 'user.browser.features'" in addition to "k_event" because some applications/queries use "eventid" instead of "event" version 1.3.2 - june 13 2007 - Changed definition for 'p_window_offscreenBuffering' to return string values instead of -1 when undefined - Now uses "typeof != 'undefined'" for compatMode, xmlEncoding and xmlVersion too version 1.3.1 - june 6 2007 - Set REQUIRED_PROTOTYPE to '1.5.0' (was '1.5.1'). version 1.3.0 - june 6 2007 - Added function 'buildversion' - Changed function 'version' to include 'buildversion' - changed return value to -1 instead of 'undefined' for features that return numeric value - changed return value to 'undefined' instead of '' version 1.2 - may 23 2007 - added Flash Player detection with SWFObject - detect window dimensions with Knowmax Measurement Utility version 1.1 - may 22 2007 - added browser specific (IE) features for script engine - commented out 'not client specific' features, leave in code version 1.0 - april 11 2007 - initial version Todo: - iets met REQUIRED_SWFOBJECT vgl prototype (maar zit niet in de library, zelf uitbreiden of verzoeken) - implement Media Player detection? - implement Acrobat Reader detection? Notes: - mimetypes and plugins array cannot be questioned in IE (c) 2007 Knowmax */ var KMBrowserFeatures = { majorversion: function() { return 1; }, minorversion: function() { return 3; }, buildversion: function() { return 3; }, version: function() { return this.majorversion() + "." + this.minorversion() + "." + this.buildversion(); }, // Internally called to set default values. _construct: function() { this._initialized = false; this._enabled = true; this._browserfeatures = null; }, REQUIRED_PROTOTYPE: '1.5.0', REQUIRED_KMMEASUREMENT: '1.3.0', REQUIRED_SWFOBJECT: '1.5.0', initialize: function() { if (!this._initialized) { function convertVersionString(versionString){ var r = versionString.split('.'); return parseInt(r[0])*100000 + parseInt(r[1])*1000 + parseInt(r[2]); } if ((typeof Prototype =='undefined') || (typeof Element == 'undefined') || (typeof Element.Methods=='undefined') || (convertVersionString(Prototype.Version) < convertVersionString(KMBrowserFeatures.REQUIRED_PROTOTYPE))) { throw("KMBrowserFeatures requires the Prototype JavaScript framework >= " + KMBrowserFeatures.REQUIRED_PROTOTYPE); } else if (convertVersionString(KMMeasurement.version()) < convertVersionString(KMBrowserFeatures.REQUIRED_KMMEASUREMENT)) { throw("KMBrowserFeatures requires the Knowmax Measurement Utility Unit >= " + KMBrowserFeatures.REQUIRED_KMMEASUREMENT); } else { this.setBrowserFeatures(); this._initialized = true; return true; } } else { return true; } }, setBrowserFeatures: function() { // try to set cookie, needed for document_cookie try { document.cookie = "cookies=true"; } catch(err) { } // collect browserfeatures in hash try { var list = new Hash({ k_event: 'user.browser.features', k_eventid: 'user.browser.features', k_module: 'kmbrowserfeatures', p_document_all: (document.all) ?
