How can i detect that the b开发者_JS百科rowser is Safari 5 or higher?

I think you want to know if Safari is v5 or higher because of some feature.

In this case you can use also http://api.jquery.com/jQuery.support/

Here's a good article on this topic:

A bit more involved and with more code than maybe you are looking for, but it should certinaly help!
