$scope.data = [
    {
    "name": "Jim",
    "id" : 25
    },
    {
    "name": "Jerry",
    "id": 27
    },
    {
    "name": "Rithika",
    "id": 20
    }
    ];

    <div ng-repeat="person in data | filter: {id:20}">
        {{parent_index}}
    </div>

parent_index - 实际数组中已过滤元素的索引.

在这个例子中,parent_index应该返回2.如何找到它？
