|
| - * The `auto-binding` element extends the template element. It provides a quick
|
| - * and easy way to do data binding without the need to setup a model.
|
| - * The `auto-binding` element itself serves as the model and controller for the
|
| - * elements it contains. Both data and event handlers can be bound.
|
| - *
|
| - * The `auto-binding` 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.
|
| - *
|
| - * Example:
|
| - *
|
| - * <template is="auto-binding">
|
| - * <div>Say something: <input value="{{value}}"></div>
|
| - * <div>You said: {{value}}</div>
|
| - * <button on-tap="{{buttonTap}}">Tap me!</button>
|
| - * </template>
|
| - * <script>
|
| - * var template = document.querySelector('template');
|
| - * template.value = 'something';
|
| - * template.buttonTap = function() {
|
| - * console.log('tap!');
|
| - * };
