//jquery to Judge browser information


$ (function () {

var bro_msie=bro.msie;//judge whether IE browser, if for IE browser, return: True, otherwise return: undefined;

var ie_ver=bro.version;//ie6, return "6.0", IE7 Return "7.0", IE8 return "8.0", IE9 return "9.0", etc.


});





//Native JavaScript judge browser information


//Judge whether the browser is IE, Method 1


var isie=document.all? ' IE ': ' others '///under IE document.all value is 1 (true), while other browsers have a value of 0 (false);





//Judge whether 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);





//Judge IE version


var isie6=bro.indexof ("MSIE 6.0") >0? ' IE6 ': ' other version ';//Under IE6 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 ';//Under IE7 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 ';//Under IE8 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 ';//Under IE9 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 ';//Under Firefox bro.indexof ("Firefox") value is greater than 1, while other browsers under the value of less than 0 (generally 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 ';//Under Chrome Bro.indexof ("Chrome") value 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 Bro.indexof ("opera") value is greater than 1, while the value under other browsers is less than 0 (generally-1);(p s: seems invalid)


var iscamino=bro.indexof ("Camino") >0? ' Camino ': ' other version ';//Under Camino bro.indexof ("Camino") value is greater than 1, while the value under other browsers is less than 0 (typically-1);
