javascript - jQuery browser detection? -

-

is there way detect if user's browser internet explorer using jquery?

i have issue png graphics using ie , want swap them gif's if user viewing site ie.

you can using $.browser, yes, it's bad idea use browser detection:

if($.browser.msie) { /* ie */ }

a better option instance $.support feature detection, this:

if(!$.support.opacity) { /* ie 6-8 */ }

$.support.opacity false in browsers don't support opacity in styling (though ie 7-8 handle transparent pngs file, still isn't ideal, depending on you're after...personally think you'd giving ie 7/8 users sub-optimal experience).

what should really target ie6 doesn't support transparent pngs (without alpha filter), this:

<!--[if ie 6]>   <link rel="stylesheet" type="text/css" href="ie6imagestyles.css"> <![endif]-->

i define tasks using nsdictionary, i'd save in plist file (i didn't have luck core data far), got stuck @ 2 points: -- when using initwithobjectsandkeys: can change data type number or boolean, using nsdate's numberwithint: , numberwithbool: methods, respectively. can't seem find method change type date though. couldn't find in documentation. -- second problem ran nested arrays. how can add them dictionary? i have uploaded picture here of trying achieve. thank in advance! do mean nsnumber 's +numberwithint: , +numberwithbool: methods, not nsdate ? it's nsnumber defines methods. to convert number date, depends on number is. if it's unix timestamp, [nsdate datewithtimeintervalsince1970:thetimestampinseconds] . as adding nsarray objects dictionary: [yourdictionary setobject:yourarray forkey:@"somekey"]; you'll have post code if need more question isn't clear.
