safari: /webkit/.test( userAgent ),
opera: /opera/.test( userAgent ),
msie: /msie/.test( userAgent ) && !/opera/.test( userAgent ),

opera: /opera/.test( userAgent ),
msie: /msie/.test( userAgent ) && !/opera/.test( userAgent ),

It is recommended that friends who are learning jquery study it and understand the ideas.
Mainly used method: $.browser.['browser keyword']
The code is as follows:
Copy code The code is as follows:
