使用Ember.js拖放

Question

有没有关于如何使用Ember.js实现拖放的示例？我尝试过使用jQuery UI,但集成似乎有些复杂.

我已经看过这个jsFiddle:http://jsfiddle.net/oskbor/Wu2cu/1/但是还没能在我自己的应用程序中成功实现这个.

使用Ember.js进行相当简单的拖放实现有哪些选项？

我接过一看后由雷米夏普和实施Ember.js一个基本的例子,看到http://jsfiddle.net/pangratz666/DYnNH/.

把手:

<script type="text/x-handlebars" >
    Drag and drop the green and red box onto the blue one ...

    {{view App.Box class="box green"}}
    {{view App.Box class="box red"}}

    {{view App.DropTarget class="box blue"}}
</script>?

JavaScript:

DragNDrop = Ember.Namespace.create();

DragNDrop.cancel = function(event) {
    event.preventDefault();
    return false;
};

DragNDrop.Dragable = Ember.Mixin.create({
    attributeBindings: 'draggable',
    draggable: 'true',
    dragStart: function(event) {
        var dataTransfer = event.originalEvent.dataTransfer;
        dataTransfer.setData('Text', this.get('elementId'));
    }
});

DragNDrop.Droppable = Ember.Mixin.create({
    dragEnter: DragNDrop.cancel,
    dragOver: DragNDrop.cancel,
    drop: function(event) {
        var viewId = event.originalEvent.dataTransfer.getData('Text');
        Ember.View.views[viewId].destroy();        
        event.preventDefault();
        return false;
    }
});

App.Box = Ember.View.extend(DragNDrop.Dragable);
App.DropTarget = Ember.View.extend(DragNDrop.Droppable);?
