Droppable. jQuery UI. jQuery: The Write Less, Do More, JavaScript Library. jQuery: The Write Less, Do More, JavaScript Library. Browser. Description: Contains flags for the useragent, read from navigator.userAgent. This property was removed in jQuery 1.9 and is available only through the jQuery.migrate plugin. Please try to use feature detection instead. The $.browser property provides information about the web browser that is accessing the page, as reported by the browser itself. It contains flags for each of the four most prevalent browser classes (Internet Explorer, Mozilla, Webkit, and Opera) as well as version information. Available flags are: webkit (as of jQuery 1.4) safari (deprecated) opera msie mozilla This property is available immediately.
Because $.browser uses navigator.userAgent to determine the platform, it is vulnerable to spoofing by the user or misrepresentation by the browser itself.
