Note the change in spelling. It's not "Javascript MVC". I've excised the space. It turns out that 1) google is much friendlier to inquiries about "JavascriptMVC" and 2) the man behind the framework, Justin Meyer, thinks that's the correct spelling. If his code is good enough for me, then so is his spelling. Plus he reached out personally, so I am now a loyal friend.
Anyway, this looks like it's going to work. I got it installed in Visual Studio (though I am seriously thinking about moving out of there soon for these Javascript projects). 'Hello World' came up smoothly. It took stepping through the code in Firebug to figure out what folder to put my style sheets in ("stylesheets", not "styles" or "css" or, whatever), but the framework includes them correctly.
I am having a bit of a hassle trying to get the system to recognize a view. The documentation wiki has a nice page that purports to explain how to use the view/templating system. I created a simple template and tried to activate it with the code on the page "html= new View..." but it didn't work. I asked on the google group and was told to review the getting started video. I did and, yes, there was a line of code that was different ("this.view('viewName'..."). I'm not sure what the example on the wiki page is about, but what the heck, it is progress.
Next up, mime types. I'm using IIS7 and that means that it won't just serve any old file. In particular, it won't serve the javascript template files with the extension ".ejs".
First, .htaccess == website.config. They are entirely different. .htaccess is an antique format with inscrutable language. website.config is a modern (xml) format with inscrutable language. The cool thing is that you can define mime types in website.config. If that's possible with .htacess, I've not run into it. You can find an explanation and the source of my code sample on a nice IIS website, here.
I added code to tell it to serve .ejs files as text/javascript and it seems to get them. Still doesn't work, but that's why I continue to be alive. To make things work.
