jquery determines browser information
$ (function () {
var bro=$.browser;//get browser user agent information;
var bro_msie=bro.msie;//determine whether it is IE browser, if for IE browser return: True, otherwise return: undefined;
var bro_firefox=bro.mozilla;//to determine whether it is Firefox browser, if it is the Firefox browser return: True, otherwise return: undefined;

});

Native JavaScript to determine browser information
Determine if the browser is IE, Method 1
var isie=document.all? ' IE ': ' others ';//document.all value is 1 (true) under IE, while other browsers have a value of 0 (false);

Determine if the browser is IE, Method 2
var bro=navigator.useragent;//get browser user agent information;
var isie2=bro.indexof ("MSIE") >0? ' IE ': ' others ';//Under IE bro.indexof ("MSIE") value is greater than 1, while the value under other browsers is less than 0 (typically-1);

Determine the version of IE
var isie6=bro.indexof ("MSIE 6.0") >0? ' IE6 ': ' other version ';//IE6 The value of Bro.indexof ("MSIE 6.0") is greater than 1, while the value under other browsers is less than 0 (typically-1);
var isie7=bro.indexof ("MSIE 7.0") >0? ' IE7 ': ' other version ';//IE7 The value of Bro.indexof ("MSIE 7.0") is greater than 1, while the value under other browsers is less than 0 (typically-1);
var isie8=bro.indexof ("MSIE 8.0") >0? ' IE7 ': ' other version ';//IE8 The value of Bro.indexof ("MSIE 8.0") is greater than 1, while the value under other browsers is less than 0 (typically-1);
var isie9=bro.indexof ("MSIE 9.0") >0? ' IE7 ': ' other version ';//IE9 The value of Bro.indexof ("MSIE 9.0") is greater than 1, while the value under other browsers is less than 0 (typically-1);
var isfirefox=bro.indexof ("Firefox") >0? ' Firefox ': ' other version ';//In Firefox the value of Bro.indexof ("Firefox") is greater than 1, while the value under other browsers is less than 0 (typically-1);
var issafari=bro.indexof ("Safari") >0? ' Safari ': ' other version ';//Under Safari the value of Bro.indexof ("Safari") is greater than 1, while the value under other browsers is less than 0 (typically-1);
var ischrome=bro.indexof ("Chrome") >0? ' Chrome ': ' other version ';//The Value of Bro.indexof ("Chrome") under Chrome is greater than 1, while the value under other browsers is less than 0 (typically-1);
var isopera=bro.indexof ("Opera") >0? ' Opera ': ' other version ';//under Opera The value of Bro.indexof ("opera") is greater than 1, while the value under other browsers is less than 0 (typically-1);(p s: seems invalid)
var iscamino=bro.indexof ("Camino") >0? ' Camino ': ' other version ';//Camino The value of Bro.indexof ("Camino") is greater than 1, while the value under other browsers is less than 0 (typically-1);
var ismozilla=bro.indexof ("gecko/") >0? ' Gecko ': ' other version ';//under Mozilla Bro.indexof ("gecko/") value is greater than 1, while the value under other browsers is less than 0 (typically-1);
