過濾器對象數據angularjs

Question

我想通過條形碼過濾我的庫存，我可以這樣做嗎？這裏的要點是，如果條形碼我傳遞的是等於庫存[i]條形碼（在服務器中），則將$scope.inventories更改爲僅限條形碼匹配的條形碼。然後$ scope.inventories只包含匹配的條形碼庫存。

有一些瘋狂的錯誤。任何幫助，如何過濾對象數據？

$scope.inventories = new Inventory().query().$object; 

$scope.filter = function(barcode) { 
     for(var i = 0; i < $scope.inventories.length; i++){ 
      if($scope.inventories[i].barcode == barcode){ 
       $scope.inventories = $scope.inventories[i]; 
      } 
     } 
    }; 

模板

<ul ng-repeat="inventory in inventories"> 
    <li><a href="" ng-click="filter(inventory.barcode)">{{inventory.barcode}}</a></li> 
</ul> 

Answer 1

用於過濾項

$scope.filter = function(barcode) { 
     var filtered = []; 
     for(var i = 0; i < $scope.inventories.length; i++){ 
      if($scope.inventories[i].barcode == barcode){ 
       filtered.push($scope.inventories[i]); 
      } 
     } 
     $scope.filtered_inventories = filtered; 
    };

定義過濾器創建不同的變量名：在列表中NG-重複

$scope.filterByBarcode = function(list, barcode) { 
    return list.filter(function(item){ 
     return item.barcode === barcode; 
    }); 
}; 

篩選：

<ul ng-repeat="inventory in filterByBarcode(inventories, barcode)"> 
    <li><a href="" ng-click="inventory">{{inventory.barcode}}</a></li> <!-- Not sure if this is what you want to display --> 
</ul>
