Adding a click event to an element?

阅读更多关于 Adding a click event to an element?

How can one assign a click event to an arbitrary span ( eg. foo ) in an ST2 app? I have a trivial example that illustrates the idea of what I'd like to do. In the example, I write the letters A,B,C and I'd like to tell the user which letter they clicked. Here's an image: CODE SNIPPET Ext.application({ launch: function() { var view = Ext.create('Ext.Container', { layout: { type: 'vbox' }, items: [{ html: 'A B C', style: 'background-color: #c9c9c9;font-size: 48px;', flex: 1 }] });

阅读更多关于 A solid tutorial for Sencha Touch V2 [closed]

I found a great tutorial on creating an MVC App from Scratch using Sencha Touch V1.1 but unfortunately it isn't all that applicable to Sencha Touch V2. I want to learn the new/right way to build an MVC app moving forward with their latest framework. Any good tutorial for building an MVC App using Sencha Touch V2? Here's a list of places I've already looked. Official Docs Videos are outdated Examples don't show source snippets, you have to "View Source" and try to wade through the compressed/minified versions of the library. Documentation doesn't describe MVC at all (just try searching for "mvc
