我有一系列带有属性＆＃39; orderNumber＆＃39;在模型中。我需要我的头像集合按“订单号”排序。领域。每个对象都有它的orderNumber，如果你在robomongo中更改了对象的orderNumber，那么对象会因为它的“订单号”而交换。号。
这是我的模特：
var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var CollectionSchema = new Schema({
name: {
type: String,
required: 'Name is required!'
},
description: {
type: String
},
orderNumber:{
type: Number
},
defaultAvatar: [{
type: Schema.Types.ObjectId,
ref: 'Part'
}],
designer_id: {
type: Schema.Types.ObjectId,
ref: 'Designer'
},
pipeline: [{
name: {
type: String,
required: 'Pipeline step name is required!'
},
zoom: Boolean,
templates: [{
name: {
type: String,
required: 'Template name is required!'
},
parts: [{
type: Schema.Types.ObjectId,
ref: 'Part'
}]
}]
}]
});
module.exports = mongoose.model('Collection', CollectionSchema);>

您可以使用角度过滤器＆＃34; orderBy＆＃34;对您的收藏品进行排序。
参考：http://justinklemm.com/angularjs-filter-ordering-objects-ngrepeat/
如果你想在javascript中使用这个过滤器而不是在ng-repeat
$filter('orderBy')(array, expression, reverse)
