Global Functions

goog.userAgent.compare(v1, v2) ⇒
number
Use goog.string.compareVersions. Compares two version numbers.
Arguments:
v1 :
string
Version of first item.
v2 :
string
Version of second item.
Returns: 
number
  1 if first argument is higher 0 if arguments are equal -1 if second argument is higher.
code »
goog.userAgent.determinePlatform_() ⇒
string
No description.
Returns: 
string
  the platform (operating system) the user agent is running on. Default to empty string because navigator.platform may not be defined (on Rhino, for example).
code »
goog.userAgent.determineVersion_() ⇒
string
No description.
Returns: 
string
  The string that describes the version number of the user agent.
code »
goog.userAgent.getDocumentMode_() ⇒
(number | undefined)
No description.
Returns: 
(number | undefined)
  Returns the document mode (for testing).
code »
goog.userAgent.getNavigator() ⇒
(Object | null)
No description.
Returns: 
(Object | null)
  The native navigator object.
code »
goog.userAgent.getUserAgentString() ⇒
(null | string)
Returns the userAgent string for the current browser. Some user agents (I'm thinking of you, Gears WorkerPool) do not expose a navigator object off the global scope. In that case we return null.
Returns: 
(null | string)
  The userAgent string or null if there is none.
code »
goog.userAgent.initPlatform_()
Initialize the goog.userAgent constants that define which platform the user agent is running on.
code »
goog.userAgent.init_()
Initializer for goog.userAgent. This is a named function so that it can be stripped via the jscompiler option for stripping types.
code »
goog.userAgent.isDocumentMode(documentMode) ⇒
boolean
Whether the IE effective document mode is higher or the same as the given document mode version. NOTE: Only for IE, return false for another browser.
Arguments:
documentMode :
number
The document mode version to check.
Returns: 
boolean
  Whether the IE effective document mode is higher or the same as the given version.
code »
goog.userAgent.isVersion(version) ⇒
boolean
Whether the user agent version is higher or the same as the given version. NOTE: When checking the version numbers for Firefox and Safari, be sure to use the engine's version, not the browser's version number. For example, Firefox 3.0 corresponds to Gecko 1.9 and Safari 3.0 to Webkit 522.11. Opera and Internet Explorer versions match the product release number.
Arguments:
version :
(number | string)
The version to check.
Returns: 
boolean
  Whether the user agent version is higher or the same as the given version.

Global Properties

goog.userAgent.BROWSER_KNOWN_ :
boolean
Whether we know the browser engine at compile-time.
Code »
goog.userAgent.GECKO :
boolean
Whether the user agent is Gecko. Gecko is the rendering engine used by Mozilla, Mozilla Firefox, Camino and many more.
Code »
goog.userAgent.IE :
boolean
Whether the user agent is Internet Explorer. This includes other browsers using Trident as its rendering engine. For example AOL and Netscape 8
Code »
goog.userAgent.LINUX :
boolean
Whether the user agent is running on a Linux operating system.
Code »
goog.userAgent.MAC :
boolean
Whether the user agent is running on a Macintosh operating system.
Code »
goog.userAgent.MOBILE :
boolean
Whether the user agent is running on a mobile device.
Code »
goog.userAgent.OPERA :
boolean
Whether the user agent is Opera.
Code »
goog.userAgent.PLATFORM :
string
The platform (operating system) the user agent is running on. Default to empty string because navigator.platform may not be defined (on Rhino, for example).
Code »
goog.userAgent.PLATFORM_KNOWN_ :
boolean
No description.
Code »
goog.userAgent.SAFARI :
boolean
Used while transitioning code to use WEBKIT instead.
Code »
goog.userAgent.VERSION :
string
The version of the user agent. This is a string because it might contain 'b' (as in beta) as well as multiple dots.
Code »
goog.userAgent.WEBKIT :
boolean
Whether the user agent is WebKit. WebKit is the rendering engine that Safari, Android and others use.
Code »
goog.userAgent.WINDOWS :
boolean
Whether the user agent is running on a Windows operating system.
Code »
goog.userAgent.X11 :
boolean
Whether the user agent is running on a X11 windowing system.
Code »
goog.userAgent.detectedGecko_ :
boolean
Whether the user agent string denotes Gecko. Gecko is the rendering engine used by Mozilla, Mozilla Firefox, Camino and many more.
Code »
goog.userAgent.detectedIe_ :
boolean
Whether the user agent string denotes Internet Explorer. This includes other browsers using Trident as its rendering engine. For example AOL and Netscape 8
Code »
goog.userAgent.detectedLinux_ :
boolean
Whether the user agent is running on a Linux operating system.
Code »
goog.userAgent.detectedMac_ :
boolean
Whether the user agent is running on a Macintosh operating system.
Code »
goog.userAgent.detectedMobile_ :
boolean
Whether the user agent string denotes a mobile device.
Code »
goog.userAgent.detectedOpera_ :
boolean

goog.userAgent.detectedWindows_ :
boolean
Whether the user agent is running on a Windows operating system.
Code »
goog.userAgent.detectedX11_ :
boolean
Whether the user agent is running on a X11 windowing system.
Code »
goog.userAgent.isDocumentModeCache_ :
(Object | null)
Cache for goog.userAgent.isDocumentMode. Browsers document mode version number is unlikely to change during a session we cache the results.
Code »
goog.userAgent.isVersionCache_ :
(Object | null)
Cache for goog.userAgent.isVersion. Calls to compareVersions are surprisingly expensive and as a browsers version number is unlikely to change during a session we cache the results.
