将一个HTML表的<tbody>元素指定为Marionette for Backbone.js中的一个区域

Question

问题

使用Backbone.Marrionette.Layout来呈现一些表格数据.<tbody>表的一部分是Backbone.Marionette.Region,用于显示Backbone.Marionette.CollectionView.

我无法弄清楚如何使用Marionette的"区域"来做到这一点,而不会通过在<tbody>元素中插入额外的HTML元素来搞乱表格显示.

示例代码

该Layout如下所示:

Backbone.Marionette.Layout.extend({
    template:...
    regions:{
        list_region: '#list-region'
    }
    onRender:function(){
        var collection = new TheCollection()
        var collectionView = new TheCollectionView({
            collection: collection
        })
        // PROBLEM: The region seems to needs its own HTML element,
        //   and the CollectionView also seems to need its on HTML
        //   element, but as far as I can see, there is only room 
        //    for one element: <tbody>?
        this.list_region.show(collectionView);
});

布局的模板包含整个表格:

<table>

    <tbody id='list-region'>

    </tbody>

    <tfoot id='footer-region'>
        Some other stuff goes here that is not a collection, so I was able 
        to make the View's 'tagName' property 'tr', which worked fine.
    </tfoot>

</table>

有什么建议？

Answer 1

这种布局的目的仅仅是为了方便一张桌子吗？如果是这样,您应该考虑使用CompositeView.

RowView = Marionette.ItemView.extend({
  tagName: "tr",
  template: ...
});

TableView = Marionette.CompositeView.extend({
  template: ...,

  childView: RowView,

  childViewContainer: "#list-region"
});

这就是它.这会将所有itemView渲染到tbody中.
