/* PROOFING AND REPORTING TOOL ===================================== Revised 07 Jan 2001 to include check for RealPlayer, have warnings. Revised 14 Nov 2000 to add reporting and minimum requirements options. Run on launch index.html to check for presence of minimum site requirements, so we dont waste time and money on false feedback, and educate the user. ---------------------------------------------------------------------------------------- Ultimate client-side JavaScript client sniff. (C) Netscape Communications 1999. Permission granted to reuse and distribute. Revised 17 May 99 to add is.nav5up and is.ie5up (see below). Everything you always wanted to know about your JavaScript client but were afraid to ask ... "Is" is the constructor function for "is" object, which has properties indicating: (1) browser vendor: is.nav, is.ie, is.opera (2) browser version number: is.major (integer indicating major version number: 2, 3, 4 ...) is.minor (float indicating full version number: 2.02, 3.01, 4.04 ...) (3) browser vendor AND major version number is.nav2, is.nav3, is.nav4, is.nav4up, is.ie3, is.ie4, is.ie4up, is.ie5, is.ie5up (4) JavaScript version number: is.js (float indicating full JavaScript version number: 1, 1.1, 1.2 ...) (5) OS platform and version: is.win, is.win16, is.win32, is.win31, is.win95, is.winnt, is.win98 is.os2 is.mac, is.mac68k, is.macppc is.unix is.sun, is.sun4, is.sun5, is.suni86 is.irix, is.irix5, is.irix6 is.hpux, is.hpux9, is.hpux10 is.aix, is.aix1, is.aix2, is.aix3, is.aix4 is.linux, is.sco, is.unixware, is.mpras, is.reliant is.dec, is.sinix, is.freebsd, is.bsd is.vms See http://www.it97.de/JavaScript/JS_tutorial/bstat/navobj.html and http://www.it97.de/JavaScript/JS_tutorial/bstat/Browseraol.html for detailed lists of userAgent strings. Note: you don't want your Nav4 or IE4 code to "turn off" or stop working when Nav5 and IE5 (or later) are released, so in conditional code forks, use is.nav4up ("Nav4 or greater") and is.ie4up ("IE4 or greater") instead of is.nav4 or is.ie4 to check version in code which you want to work on future versions. */ function Is() { // convert all characters to lowercase to simplify testing var agt=navigator.userAgent.toLowerCase(); // BROWSER VERSION // =================== // Note: On IE5, these return 4, so use is.ie5up to detect IE5. this.major = parseInt(navigator.appVersion); this.minor = parseFloat(navigator.appVersion); this.nav = ((agt.indexOf('mozilla')!=-1) && (agt.indexOf('spoofer')==-1) && (agt.indexOf('compatible') == -1) && (agt.indexOf('opera')==-1) && (agt.indexOf('webtv')==-1)); this.nav2 = (this.nav && (this.major == 2)); this.nav3 = (this.nav && (this.major == 3)); this.nav4 = (this.nav && (this.major == 4)); this.nav4up = (this.nav && (this.major >= 4)); this.navonly = (this.nav && ((agt.indexOf(";nav") != -1) || (agt.indexOf("; nav") != -1)) ); this.nav5 = (this.nav && (this.major == 5)); this.nav5up = (this.nav && (this.major >= 5)); this.ie = (agt.indexOf("msie") != -1); this.ie3 = (this.ie && (this.major < 4)); this.ie4 = (this.ie && (this.major == 4) && (agt.indexOf("msie 5.0")==-1) ); this.ie45 = (this.ie && (this.major == 4) && (agt.indexOf("msie 4.5")==-1) ); this.ie4up = (this.ie && (this.major >= 4)); this.ie5 = (this.ie && (this.major == 4) && (agt.indexOf("msie 5.0")!=-1) ); this.ie55 = (this.ie && (this.major == 4) && (agt.indexOf("msie 5.5")!=-1) ); this.ie5up = (this.ie && !this.ie3 && !this.ie4); // KNOWN BUG: On AOL4, returns false if IE3 is embedded browser // or if this is the first browser window opened.
