问题描述
从谷歌得到它看起来像AngularFire曾经有一个orderByPriority过滤器。 。据我了解，orderByPriority转换一个对象的属性到一个数组。我想这过滤器了，因为有另一个更好的办法现在就这样做，但什么是法？
From Google result it looks like AngularFire used to have a orderByPriority filter. But I cannot find this in the current AngularFire api docs: https://www.firebase.com/docs/web/libraries/angular/api.html. As I understand it, orderByPriority converted an objects properties into to an array. I guess this filter is gone because there is another and better way to do it now, but what is that method?
推荐答案
有不再需要 orderByPriority ，因为你可以利用同步阵列，这已经是隐含订购。
There is no longer a need for orderByPriority since you can utilize a synchronized array, which is already implicitly ordered.
因此，在远古时代，你会做这样的事情：
So in ancient days, you would do something like:
$scope.data = $firebase(ref);
<div ng-repeat="item in data | orderByPriority" />
在不那么远古时代（即0.8.4或更高版本），你会简单地选择一个阵列格式为：
In not so ancient times (i.e. 0.8.x or greater) you would simply choose an array format:
$scope.data = $firebase(ref).$asArray();
<div ng-repeat="item in data" />
