I think, if possible, the browser detection should check browsers
through something other than the user agent.
// Figure out what browser is being used
jQuery.browser = {
safari: /webkit/.test(b),
opera: !!window.opera,
msie: /[EMAIL PROTECTED]
/[EMAIL PROTECTED] (@_jscript)
true
@else @*/
false
/[EMAIL PROTECTED] @*/
mozilla: !!window.Components
};
This assumes no one creates an object called 'opera' or 'Comnponents'
on the window object. I'm not sure what is unique in Safari as I can't
find any pages on Apple detailing the DOM in Safari.
Not friendly with Dean Edwards' packer tool though, which won't be
able to compress any code that uses conditional comments without
breaking it.
