                "VariantID": "10",
                "VariantName": "1 L",
                "InCart": "2",
                "MRP": "115.00",
                "VariantImagePath": "/images/ruchi/710_10.png"
            },
            {
                "SellPrice": "410.00",
                "VariantID": "113",
                "VariantName": "5 L",
                "InCart": "1",
                "MRP": "485.00",
                "VariantImagePath": "/images/ruchi/710_113.png"

                "SellPrice": "1080.00",
                "VariantID": "219",
                "VariantName": "15L - Jar",
                "InCart": "0",
                "MRP": "1275.00",
                "VariantImagePath": "/images/ruchi/710_219.png"
            }
        ],
        "SubCategoryID": "32",
        "ProductImagePath": "/images/ruchi/710.png",
        "SubCategoryName": "Soyabean Oil",
        "BrandName": "Ruchi",
        "ProductID": "710",
        "BrandID": "117",
        "ProductName": "Ruchi soya oil"
    },
    {
        "Variants": [
            {
                "SellPrice": "58.00",
                "VariantID": "23",
                "VariantName": "900 GM",
                "InCart": "1",
                "MRP": "60.00",
                "VariantImagePath": "/images/mtr/771_23.png"
            }
        ],
        "SubCategoryID": "110",
        "ProductImagePath": "/images/mtr/771.png",
        "SubCategoryName": "Vermicelli",
        "BrandName": "MTR",
        "ProductID": "771",
        "BrandID": "167",
        "ProductName": "Seviyan Vermicelli"
    }
]

Want to filter all the data where Variants.InCart value is > 0.

In this case output will be

ProductID   VariantID   InCart
710         113         1
710         10          2
771         23          1

and this is my loop.

<tr ng-repeat="Item in ProductService.Products | <what should be filter condition here>">
    <td>{{Item.ProductID}} {{Item.Variants.VariantID}} {{Item.Variants.InCart}}</td>
</tr>

Please help.

Answer 1

<tr ng-repeat="Item in ProductService.Products | filter:customArrayFilter">
    <td>{{Item.ProductID}} {{Item.Variants.VariantID}} {{Item.Variants.InCart}}</td>
</tr>

$scope.customArrayFilter = function (item) {
      return (item.InCart > 0);
    };

You can add custom filter like this..
