(ie5.5 mididentified - abk) 23// is_ie4 mod tp work with ie6+ - abk 24// 001120 - ns6 released, document.layers false, put back in 25// - is_nav6 test added - abk 26// 001121 - ns6+ added, used document.getElementById, better test, dom-compl 27// 010117 - actual version for ie3-5.5 by Michel Plungjan 28// 010118 - actual version for ns6 by Michel Plungjan 29// 010217 - netscape 6/mz 6 ie5.5 onload defer bug docs - abk 30// 011107 - added is_ie6 and is_ie6up variables - dmr 31// 020128 - added link to netscape's sniffer, on which this is based - abk 32// updated sniffer for aol4-6, ie5mac = js1.4, TVNavigator, AOLTV, 33// hotjava 34// 020131 - cleaned up links, added more links to example object detection 35// 020131 - a couple small problems with Opera detection. First, when Opera 36// is set to be compatible with other browsers it will contain their 37// information in the userAgent strings. Thus, to be sure we have 38// Opera we should check for it before checking for the other bigs. 39// (And make sure the others are !opera.) Also corrected a minor 40// bug in the is_opera6up assignment. 41// 020214 - Added link for Opera/JS compatibility; added improvements for 42// windows xp/2000 id in opera and aol 7 id (thanks to Les 43// Hill, [email protected], for the suggestion). 44// 020531 - Added N6/7 and moz identifiers. 45// 020605 - Added mozilla guessing, Netscape 7 identification, and cleaner 46// identification for Netscape 6. (this comment added after code 47// changes) 48// 020725 - Added is_gecko. -- dmr 49// 021205 - Added is_Flash and is_FlashVersion, based on Doc JavaScript code. 50// Added Opera 7 variables. -- dmr 51// 021209 - Added aol8. -- dmr 52// 030110 - Added is_safari, added 1.5 js designation for Opera 7. --dmr 53// 030128 - Added is_konq, per user suggestion (thanks to Sam Vilain). 54// Removed duplicate Opera checks left over after last revision. - dmr 55// 56// Everything you always wanted to know about your JavaScript client 57// but were afraid to ask.
