Native javascript and jquery determine the browser version and other information

Copy codeThe Code is as follows:
<Script type = "text/javascript">
// Jquery determines the browser Information
$ (Function (){
Var bro = $. browser; // get the browser user proxy information;
Var bro_msie = bro. msie; // determines whether it is in IE. If it is in IE, true is returned; otherwise, undefined is returned;
Var bro_firefox = bro. mozilla; // determines whether the Firefox browser is used. If the Firefox browser is used, the return value is true; otherwise, the return value is undefined;
Var bro_opera = bro. opera; // determines whether it is an operabrowser. If it is an operabrowser, true is returned; otherwise, undefined is returned;
Var bro_safari = bro. safari; // determines whether it is a safari browser. If it is a safari browser, return: true; otherwise, return: undefined;
// Determine the browser version and use the version attribute, such as ie;
Var ie_ver = bro. version; // ie6, returns "6.0", ie7 returns "7.0", ie8 returns "8.0", ie9 returns "9.0", and so on...
});

// Native javascript determines browser Information
// Determine whether the browser is IE. method 1
Var isIE = document. all? 'Ie': 'others '; // The document. all value in IE is 1 (true), and the value in other browsers is 0 (false );

// Determine whether the browser is IE. method 2
Var bro = navigator. userAgent; // obtain the browser user proxy information;
Var isIE2 = bro. indexOf ("MSIE")> 0? 'Ie': 'others '; // in IE, the bro. indexOf ("MSIE") value is greater than 1, and in other browsers, the value is smaller than 0 (generally-1 );

// Determine the IE version
Var isIE6 = bro. indexOf ("MSIE 6.0")> 0? 'Ie6': 'Other version'; // in IE6, bro. the value of indexOf ("MSIE 6.0") is greater than 1, and the value of other browsers is smaller than 0 (generally-1 );
Var isIE7 = bro. indexOf ("MSIE 7.0")> 0? 'Ie7': 'Other version'; // In IE7, bro. the value of indexOf ("MSIE 7.0") is greater than 1, and the value of other browsers is smaller than 0 (generally-1 );
Var isIE8 = bro. indexOf ("MSIE 8.0")> 0? 'Ie7': 'Other version'; // In IE8, bro. the value of indexOf ("MSIE 8.0") is greater than 1, and the value of other browsers is smaller than 0 (generally-1 );
Var isIE9 = bro. indexOf ("MSIE 9.0")> 0? 'Ie7': 'Other version'; // In IE9 bro. the value of indexOf ("MSIE 9.0") is greater than 1, and the value in other browsers is smaller than 0 (generally-1). So on...
Var isFirefox = bro. indexOf ("Firefox")> 0? 'Firefox ': 'Other version'; // in Firefox, bro. the value of indexOf ("Firefox") is greater than 1, and the value of other browsers is smaller than 0 (generally-1 );
Var isSafari = bro. indexOf ("Safari")> 0? 'Safari ': 'Other version'; // in Safari, bro. the value of indexOf ("Safari") is greater than 1, and the value of other browsers is smaller than 0 (generally-1 );
Var isChrome = bro. indexOf ("Chrome")> 0? 'Chrome': 'Other version'; // In Chrome, bro. the value of indexOf ("Chrome") is greater than 1, and the value of other browsers is smaller than 0 (generally-1 );
Var isOpera = bro. indexOf ("Opera")> 0? 'Opera ': 'Other version'; // under Opera bro. the indexOf ("Opera") value is greater than 1, while the value in other browsers is smaller than 0 (generally-1); (ps: It seems to be invalid)
Var isCamino = bro. indexOf ("Camino")> 0? 'Camino ': 'Other version'; // In the Camino bro. the value of indexOf ("Camino") is greater than 1, and the value of other browsers is smaller than 0 (generally-1 );
Var isMozilla = bro. indexOf ("Gecko/")> 0? 'Gecko': 'Other version'; // in Mozilla bro. the value of indexOf ("Gecko/") is greater than 1, and the value of other browsers is smaller than 0 (generally-1 );
// Alert (isOpera );
