我知道这可能已经得到了回答，但是我没有成功应用我在我的例子中找到的任何解决方案。我正在尝试使用UI Bootstrap在我的产品列表页面上启用分页，并允许用户通过搜索过滤所述结果。
我有一个定义如下的对象：
$scope.products = [{"_id": ObjectID("0000000"), "name":"Product", "description": "Product Description"}];
到目前为止，我已经能够从restangular服务中提取产品，但是当我添加分页/搜索功能时，我收到以下控制台错误：Error: [filter:notarray] Expected array but received {}。我知道我需要将我的对象转换为数组，但我无法成功转换它。我试过的两个例子发布在下面。任何帮助将不胜感激。
我的产品列表视图
<div ng-controller="paginationCtrl" class="row">
<div class="col-lg-12">
<div class="pull-left">
<form>
<div class="input-group product-searchs" ng-controller="SearchCtrl">
<label class="sr-only" for="searchProducts">Search</label>
<span class="input-group-addon search-icon"><i class="fa fa-search" aria-hidden="true"></i></span>
<input type="text" class="form-control" id="searchProducts" ng-model="search.name" placeholder="Search for products">
<span class="input-group-addon clear-icon">
<button type="button" ng-click="clearSearch()">
<i class="glyphicon glyphicon-remove" aria-hidden="true"></i>
</button>
</span>
</div>
</form>
</div>
</div>
<div class="col-lg-12">
<div class="list-group">
<a ui-sref="productDetails({id:product._id})" class="list-group-item clearfix" ng-repeat="product in filteredProducts = (products | filter: search | startFrom: (currentPage - 1) * itemsPerPage | limitTo: itemsPerPage | orderBy:orderProp)">
<div class="page-header clearfix">
<h2 class="pull-left"><i class="fa fa-diamond"></i> {{product.name}}</h2>
<span class="pull-right product-price {{product.price | currency}}</span>
</div>
{{product.description}}
</a>
</div>
</div>
<div class="col-lg-12">
<pagination class="pull-right" page="currentPage" total-items="totalItems" ng-model="currentPage" max-size="maxSize" ng-change="pageChanged() items-per-page="itemsPerPage" num-pages="numPages"></pagination>
</div>
</div>
我知道我可能会有一些额外的依赖注入，一旦我使其正常工作，我将删除它。
我的控制器
angular.module('gemStoreApp')
.controller('paginationCtrl', ['$scope', '$log', 'filterFilter', 'productsService', 'Restangular', '$filter', function ($scope, $log, filterFilter', productsService, Restangular, $filter) {
$scope.search = {}
$scope.filteredProducts = [];
//Option 1
angular.forEach($scope.products, function(product) {
$scope.filteredProducts.push(product);
});
//Option 2
//for (var key in $scope.products) {
//var tempProducts = {};
//tempProducts[key] = $scope.products[key];
//$scope.filteredProducts.push(tempProducts);
//});
$scope.currentPage = 1;
$scope.maxSize = 100;
$scope.itemsPerPage = 10;
$scope.$watch('search', function(newVal, oldVal) {
$scope.filteredProducts = filterFilter($scope.products, newVal);
$scope.totalItems = $scope.filteredProducts.length;
}, true);
//I also tried this
//$scope.$watch('search, function(newSearch) {
//$scope.filteredProducts = $filter('filter')($scope.products, $scope.search);
// $scope.totalItems = $scope.filteredProducts.length;
//});
}])
我的服务
angular.module('gemStoreApp.productService',['ngResource'])
.factory('productsService', function(Restangular) {
return Restangular.service('products');
});
我的产品控制器
angular.module('gemStoreApp')
.controller('ProductsCtrl', ['$scope', 'productsService', function ($scope, productsService) {
$scope.products = {};
productsService.getList().then(function(products){
$scope.products = products;
});
}]);
在我的app.js文件中添加了Restangular setRestangularFields和setRequestInterceptor方法，这使得搜索/过滤功能正常工作，但我仍然收到Expected array but received {}错误
RestangularProvider.setRestangularFields({
id: '_id.$oid'
});
RestangularProvider.setRequestInterceptor(function(elem, operation) {
if (operation === 'put') {
elem._id = undefined;
return elem;
}
return elem;
});
我创建了一个看似正常工作的Plunker版本。
Plunker example
创建了一个更新的Plunker，其中包含我看到的本地问题。问题是分页无法正常工作。它只显示我想要的10个项目，但点击这两个项目不会切换到第2页。Plunker example

我在你的例子中看到了一些错误。我相信你的html中不需要ng-controller =“SearchCtrl”。 此外，在ng重复中使用过滤器的要点是不使用搜索文本输入的监视事件。因此，您应该使用products数组并对其应用过滤器。如果你想使用filteredProducts，我在下面的例子中留下了一个函数。我初始化变量，因为我无法访问你的不安分api。
var app = angular.module('myApp', []);
app.filter('startFrom', function() {
return function(input, start) {
if(input) {
start = +start; //parse to int
return input.slice(start);
}
return [];
}
});
app.controller('paginationCtrl', ['$scope', '$log', '$filter', function ($scope, $log, $filter) {
$scope.search = {name: "Product"}
$scope.products = [{"_id": "0000000", "name":"Product", "description": "Product Description"},
{"_id": "0000000", "name":"Product 2", "description": "Product Description 2"}];
$scope.filteredProducts = [];
$scope.currentPage = 2;
$scope.maxSize = 100;
$scope.itemsPerPage = 10;
$scope.startFrom = ($scope.currentPage - 1) * $scope.itemsPerPage;
var filterProducts = function(newVal){
$scope.filteredProducts.splice(0, $scope.filteredProducts.length);
angular.forEach($scope.products, function(product) {
if(product.name == newVal){
$scope.filteredProducts.push(product);
}
});
}
$scope.$watch('search.name', function(newVal, oldVal) {
filterProducts(newVal);
$scope.totalItems = $scope.filteredProducts.length;
}, true);
$scope.$watch('currentPage', function(newVal, oldVal) {
$scope.startFrom = ($scope.currentPage - 1) * $scope.itemsPerPage;
}, true);
$scope.$watch('itemsPerPage', function(newVal, oldVal) {
$scope.startFrom = ($scope.currentPage - 1) * $scope.itemsPerPage;
}, true);

修改 在观察您的plunker之后，您不需要将filteredProducts添加到控制器，因为您正在视图中进行过滤。通过将filteredProducts添加到视图中，还可以使用$ scope.filteredProducts在控制器中访问它。 因此，使用下面的代码替换html的底部，并删除处理来自控制器的filteredProducts的所有代码：
<div class="col-lg-12">
<div class="list-group">
<a ui-sref="productDetails({id:product._id})" class="list-group-item clearfix" ng-repeat="product in filteredProducts = (products | filter: search.name | limitTo: itemsPerPage | startFrom: 0) ">
{{product.name}}<br/>
{{product.description}}
</a>
</div>
</div>
<div class="col-lg-12">
<pagination class="pull-right" page="currentPage" total-items="filteredProducts.length" ng-model="currentPage" max-size="maxSize" ng-change="pageChanged()" items-per-page="itemsPerPage" num-pages="numPages"></pagination>
</div>
如果您想手动完成所有操作（我不建议这样做），您必须将html更改为filteredProducts中的产品，当它开始将所有产品添加到filteredProducts列表并将您的代码保存在控制器中时。此外，当搜索为空时，您将不得不再次填充filteredProducts列表。
