Hi, I just committed a change: 3f4d5edcef3a519fd470c2622cbd60118d83b579
Is a change in MDL Button class to manage changes of classes with classList. I'm pretty happy with the results since: 1.- the resulting html code is perfect. Before there was some preceding whitespaces in html class generated code. 2.- Now if I change at runtime the classList API makes easy to add/remove class. (side note: in MDL sometimes is not as easy as remove or add a class since MDL could introduced more tags...but is part of the solution to be able to make runtime changes of behaviors associated to css classes). In the other hand, things that could be bad (or not), this is the official compatibility table of MDL browser support: Browser Support in v1 IE9IE10IE11ChromeOperaFirefoxSafariChrome (Android)Mobile Safari B A A A A A A A A A-grade browsers are fully supported. B-grade browsers will gracefully degrade to our CSS-only experience. So it seems IE9 should not be a problem since the support is B type So in order to extend the classList changes to the rest of MDL framework in FlexJS, I'm motivated to do so, but hope you could share your thoughts here. What is clear is that className management is a nightmare in the current state and we need something like this, maybe not only in MDL but in the rest of FlexJS. Thanks for your thoughts -- Carlos Rovira http://about.me/carlosrovira
