我试图弄清楚为什么我的日期范围过滤器不起作用并且我得到了错误 - [$injector:unpr] Unknown provider: dateRangeProvider <- dateRange <- dashboardController. 我尝试将“dateRange”放在我的依赖项和 $filter 中，不确定我所做的是否正确。绝对感谢任何帮助！谢谢！

我试图在两个日期之间过滤以获取产品 ID 的 HTML

<input style="width:200px; padding:10px; border-radius:4px;"type="text" placeholder="search name" ng-model='productFilter'>
<input type="date" ng-model="to_date">
<input type="date" ng-model="from_date">
<div ng-repeat="product in products | dateRange : from_date : to_date | filter: productFilter track by $index">
  <p>Total Inputs: {{product.createdAt}}{{product._id}}</p>
</div>

这是我的仪表板控制器

app.controller('dashboardController', ['$scope', '$filter', 'OpFactory', function($scope, $filter, OpFactory){

function getProducts(){
  OpFactory.getProducts(function(data){
   $scope.products = data;
   console.log("data from getProducts function in dashboardcontroller", data);
 })
}
getProducts();

$filter('dateRange', function() {
       return function( product, fromDate, toDate ) {
           var filtered = [];
           console.log(fromDate, toDate);
           var from_date = Date.parse(fromDate);
           var to_date = Date.parse(toDate);
           angular.forEach(product, function(item) {
               if(item.completed_date > from_date && product.completed_date < to_date) {
                   filtered.push(item);
               }
           });
           return filtered;
       };
   });
}]);

有一些问题，但主要问题是您如何创建过滤器。过滤器应该附加到您的模块中，例如angular.module('mymodule', []).filter('dateRange', fn).

除此之外，当过滤器尚未完全填充时，您必须处理要呈现的内容，并且您的过滤器函数中有日期product.completed_date而不是item.completed日期。

这里有一个工作示例（只是缺少输入过滤器尚未完全填充时的处理方式）：

angular.module('webapp', [])
        .filter('dateRange', function () {
             return function(product, fromDate, toDate) {
                 var filtered = [];
                 console.log(fromDate, toDate);
               
                 if (!fromDate && !toDate) {
                     return product;
                 }
                 
                 var from_date = Date.parse(fromDate);
                 var to_date = Date.parse(toDate);
                 angular.forEach(product, function(item) {
                     if (item.createdAt > from_date && item.createdAt < to_date) {
                         filtered.push(item);
                      }
                  });
               
                  return filtered;
             };
        })
        .controller('dashboardController', ['$scope', '$filter', '$timeout', function($scope, $filter, $timeout) {

            $scope.products = [];

            function getProducts() {
                $timeout(function() {
                    $scope.products = [{
                        _id: 1,
                        createdAt: new Date(2000, 1, 1)
                    }, {
                        _id: 2,
                        createdAt: new Date(2001, 1, 1)
                    }, {
                        _id: 3,
                        createdAt: new Date(2002, 1, 1),
                    }, {
                        _id: 4,
                        createdAt: new Date(2003, 1, 1)
                    }];
                }, 500);
            }

            getProducts();
        }]);

这是我想出的答案，也适用于其他感兴趣的人。

app.filter('dateRange', function () {
 return function(product, fromDate, toDate) {
     var filtered = [];
     console.log(fromDate, toDate, filtered);

     if (!fromDate && !toDate) {
         return product;
     }

     var from_date = Date.parse(fromDate);
     var to_date = Date.parse(toDate);
     angular.forEach(product, function(item) {
       console.log('in the forEach function')
       var createdAt = Date.parse(item.createdAt);
         if (from_date && to_date && createdAt > from_date && createdAt < to_date) {
           console.log('in the if statement', filtered)
           filtered.push(item);
         }
     })

    return filtered;

 };
})

我的 HTML 表格

<table class="receivingDataTable" datatable='ng' style="width: 1000px;">
 <tr>
    <th>Date</th>
    <th>Container #</th>
    <th>Cut #</th>
    <th>CTNS #</th>
    <th>Pieces</th>
    <th>Receiving #</th>
    <th>Remarks</th>
  </tr>
  <tr ng-repeat="product in filtered = (products | dateRange: from_date : to_date)">
    <td>{{product.createdAt | date: "MM/dd/yyyy"}}</td>
    <td>{{product.container_number}}</td>
    <td>{{product.cut_number}}</td>
    <td>{{product.ctns_number}}</td>
