|---|
| jQuery.support | Returns: Object |
| Added in jQuery 1.3 A collection of properties that represent the presence of different browser features or bugs. |
| jQuery.browser | Returns: Map |
| We recommend against using this property, please try to use feature detection instead (see jQuery.support). Contains flags for the useragent, read from navigator.userAgent. While jQuery.browser will not be removed from future versions of jQuery, every effort to use jQuery.support and proper feature detection should be made. |
