http://billyreisinger.com/blog Mostly s#^@ about JavaScript Tue, 08 Jul 2008 03:40:51 +0000 http://backend.userland.com/rss092 en We're using JSUnit to run tests in our build system, and we're using Bamboo to do continuous integration.  Unfortunately, the XML spit out by JSUnit is not recognizable as JUnit XML for the purposes of integrating into Bamboo.

Perhaps your value was ... http://billyreisinger.com/blog/2008/05/type-enforcement-and-argument-validation-in-javascript-saves-time/ I've stumbled across a bug in Opera 9.27 (which I dutifully reported).  Basically, if you disable a form element and use the DOM2 dispatchEvent method on the element to simulate a click, the element fires the event.  Since the element is disabled, it should not fire any click event handlers ... http://billyreisinger.com/blog/2008/05/disabled-form-element-and-dispatchevent-bug-in-opera/ I'm an encapsulation fanatic.  I love to write code where data is protected from view and unavailable for mischief.  I like the ability to react to changes to the internal state of a function.
