对我来说,将它放入视图中确实很有意义,而且,它确实是一个显示问题。
你在这里有一个例子:http: //jsfiddle.net/MikeAski/r6xcA/
车把:
<script type="text/x-handlebars" data-template-name="items">
{{#each item in controller}}
{{view App.ItemView contentBinding="item"}}
{{/each}}
</script>
<script type="text/x-handlebars" data-template-name="item">
Item: {{item.label}}
</script>
JavaScript :
App.ItemsController = Ember.ArrayController.extend({
selected: null
});
App.ItemsView = Ember.View.extend({
templateName: 'items'
});
App.ItemView = Ember.View.extend({
templateName: 'item',
classNameBindings: ['isSelected:selected'],
isSelected: function() {
var item = this.get('content'),
selected = this.getPath('controller.selected');
return item === selected;
}.property('item', 'controller.selected'),
click: function() {
var controller = this.get('controller'),
item = this.get('content');
controller.set('selected', item);
}
});
App.ItemsView.create({
controller: App.ItemsController.create({
content: [{ label: 'My first item' },
{ label: 'My second item' },
{ label: 'My third item' }]
})
}).append();
