Ember.js对象的Handlebars模板分为两组 [英] Handlebars template for Ember.js objects grouped by two
问题描述

我已经创建了垂直div元素为每个1 + 2,3 + 4,...对来设计这样的项目。如何使用把手将数据呈现到这样的网格中?我可以做的是这样的:
{{每个App.myController}}
...呈现项目。
{{/ each}}
首先,如果在布局中尽可能地尝试在CSS中执行此操作。
如果没有,最好的方法是将计算属性添加到控制器中将它们分组成对,并以这种方式进行。这样的东西:
{{每个App.myController.pairedContent}}
<! - content.firstObject - >
<! - view for content.lastObject - >
{{/ each}}
App.MyController = Ember.ArrayController.extend({
pairsContent:(function(){
return this.get内容')。reduce(function(array,object,index){
if(index%2){
array.get('lastObject')。pushObject(object)
}
else {
array.pushObject(Ember.A([object]))
}
返回数组
},Ember.A())
}) .property('content')
})
I have my data in the collection and I need to render them into the template. How can I achieve the result when the data is grouped by two? I need to sort them like this:
._______________________
| 1 | 3 | 5
|___|___|_______________
| 2 | 4 | and so on...
|___|___|_______________
I have created vertical div element for each 1+2, 3+4, ... pair to style the items like this. How can I render the data in to such grid with handlebars? All I can do is this:
{{#each App.myController}}
... render item ...
{{/each}}
Firstly, i'd attempt to do this in CSS if at all possible in your layout.
If not, your best bet would to add a computed property to your controller that groups them into pairs and do it that way. Something like this:
{{#each App.myController.pairedContent}}
<!-- view for content.firstObject -->
<!-- view for content.lastObject -->
{{/each}}
App.MyController = Ember.ArrayController.extend({
pairedContent: ( function(){
return this.get('content').reduce( function(array, object, index){
if(index % 2){
array.get('lastObject').pushObject(object)
}
else{
array.pushObject(Ember.A([object]))
}
return array
}, Ember.A())
}).property('content')
})
