how can i extend $.browser

I want to write some jquery that will extend $.browser with开发者_如何学JAVA some of my own properties. So it I can currently access $.browser.msie, how could I extend it to include $.browser.isPngSupported etc?

You can just set $.browser.isPngSupported to true or false.

However, you should be extending $.support, not $.browser.

var newData = {   'isPngSupported': true,
                  'more': 'x',
                  'evenMore':  'y' };

$.browser = $.extend( true, $.browser, newData );
