Some browser properties are attached to the Browser Object for browser and platform detection.

• Browser.Features.xpath - (boolean) True if the browser supports DOM queries using XPath.
• Browser.Features.air - (boolean) True if the browser supports AIR.
• Browser.Features.query - (boolean) True if the browser supports querySelectorAll.
• Browser.Features.json - (boolean) True if the browser has a native JSON object.
• Browser.Features.xhr - (boolean) True if the browser supports native XMLHTTP object.

'Browser.name' reports the name of the Browser as string, identical to the property names of the following Boolean values:

• Browser.ie - (boolean) True if the current browser is Internet Explorer.
• Browser.firefox - (boolean) True if the current browser is Firefox.
• Browser.safari - (boolean) True if the current browser is Safari.
• Browser.chrome - (boolean) True if the current browser is Chrome.
• Browser.opera - (boolean) True if the current browser is Opera.

In addition to one of the above properties a second property consisting of the name and the major version is provided ('Browser.ie6', 'Browser.chrome15', ...).

If 'Browser.chrome' is True, all other possible properties, like 'Browser.firefox', 'Browser.ie', ... , will be undefined.

alert(Browser.name); // Alerts "ie" in Internet Explorer, "firefox" in Mozilla Firefox, "chrome" in Google Chrome, "safari" or "opera".

if (Browser.ie){
    // This code will only run in IE
}

if (Browser.firefox2){
    // This code will only run in Firefox 2
}

if (Browser.ie6 || Browser.ie7){
    // Please upgrade your browser
}

If an IE document is set to backwards compatibility mode using the X-UA-Compatible header, then the Browser object is treated as if the earlier version of the browser is running.

'Browser.version' reports the version of the Browser as number.

alert(Browser.version); // Alerts '3.6' in FireFox 3.6.13
