-/** |
- * The `auto-binding-dart` element extends the template element. It provides a |
- * quick and easy way to do data binding without the need to setup a binding |
- * delegate or use the [templateBind] call. Both data and event handlers can be |
- * bound using the [model]. |
- * |
- * The `auto-binding-dart` element acts just like a template that is bound to |
- * a model. It stamps its content in the dom adjacent to itself. When the |
- * content is stamped, the `template-bound` event is fired. |
- * |
- * **NOTE**: It is a good idea to use an id to select these elements. During |
- * code transformation it is likely that other template elements will be |
- * inserted at the top of the body above yours, so something like |
- * querySelector('template') is likely to break when built. |
- * See http://dartbug.com/20911. |
- * |
- * Example: |
- * |
- * <template id="my-template" is="auto-binding-dart"> |
- * <div>Say something: <input value="{{value}}"></div> |
- * <div>You said: {{value}}</div> |
- * <button on-tap="{{buttonTap}}">Tap me!</button> |
- * </template> |
- * <script type="application/dart"> |
- * import 'dart:html'; |
- * import 'package:polymer/polymer.dart'; |
- * |
- * main() { |
- * var template = document.querySelector('#my-template'); |
- * template.model = new MyModel(); |
- * } |
- * |
- * class MyModel { |
- * String value = 'something'; |
- * buttonTap() => console.log('tap!'); |
- * } |
- * </script> |
