问题
使用Backbone.Marrionette.Layout来呈现一些表格数据。该表的<tbody>
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“Regions”来解决这个问题,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
Layout
看起来像这样:
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>
有什么建议吗?

此布局的目的仅仅是为了方便桌子吗?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。

Marionette 3弃用了CompositeView
类。相反,一个区域现在可以使用所呈现的内容覆盖其el
内部视图与new replaceElement
option。
请参阅this example以呈现表格:
var RowView = Marionette.View.extend({
tagName: 'tr',
template: '#row-template'
});
var TableBody = Marionette.CollectionView.extend({
tagName: 'tbody',
childView: RowView
});
var TableView = Marionette.View.extend({
tagName: 'table',
className: 'table table-hover',
template: '#table',
regions: {
body: {
el: 'tbody',
replaceElement: true
}
},
onRender: function() {
this.showChildView('body', new TableBody({
collection: this.collection
}));
}
});
var list = new Backbone.Collection([
{id: 1, text: 'My text'},
{id: 2, text: 'Another Item'}
]);
var myTable = new TableView({
collection: list
});
myTable.render();
