下面是一些另类的但挺高效的浏览器探测技巧,主要利用了各浏览器的私有特征完成。
进入正题:
//Firefox detector 2/3 by DoctorDan(slackers论坛) FF=/a/[-1]=='a' //Firefox 3 FF3=(function x(){})[-5]=='x' //Firefox 2 FF2=(function x(){})[-6]=='x' //IE IE='\v'=='v' //Safari Saf=/a/.__proto__=='//' //Chrome Chr=/source/.test((/a/.toString+'')) //Opera by me Op=/^function \(/.test([].sort) //IE6 try {IE6=@cc_on @_jscript_version <= 5.7&&@_jscript_build<10000} catch(e){IE6=false;}
整合到一行:
B=(function x(){})[-5]=='x'?'FF3':(function x(){})[-6]=='x'?'FF2':/a/
