Thanks for this. Looking at the core.js, it looks like Tapestry 4 uses much simpler selectors, mostly selecting elements by their id.
That's one of the things I'm still thinking about: T5 uses advanced CSS selectors in many places. Both jQuery and Prototype offer that feature, but it'll be a lot of work to implement if the target JavaScript framework doesn't offer it. The easy way (for me) is to expect the framework-specific implementation to support CSS selectors, the hard way would be to rewrite all areas using advanced selectors in the Tapestry.js file to use more simple selectors. regards, Onno On Tue, Jun 16, 2009 at 1:50 PM, Andreas Andreou <andy...@di.uoa.gr> wrote: > For reference, here's the js abstraction that T4 ended up with > > https://svn.apache.org/repos/asf/tapestry/tapestry4/trunk/tapestry-framework/src/js/tapestry-4.1.6/skeleton/core.js > > The dojo0.4.3 (& default) implementation is at: > > https://svn.apache.org/repos/asf/tapestry/tapestry4/trunk/tapestry-framework/src/js/tapestry-4.1.6/ > but there's a jquery one at: > > https://tacos.svn.sourceforge.net/svnroot/tacos/tacos-4.1/trunk/tacos-jquery/src/js/tacos-jquery-js/tap-jquery1.2.1.js > and the (incomplete) dojo 1.x at: > > https://tacos.svn.sourceforge.net/svnroot/tacos/tacos-4.1/trunk/tacos-dojo/src/js/tacos-dojo-js/tap-dojo1.0.2.js > > There was the concept of a JavascriptManager that basically groups a > set of js and css files and can include > them in a page - within the same app, different pages can use > different JavascriptManagers... sounds similar to > the stack concept that Howard mentioned recently. > > Finally, since IMHO components/widgets cannot really be cross-library > without sacrificing features, e.t.c. > there is the concept of component replacements - this is an > application level configuration that can replace > any given component with a different one...
