Question

如何在以下代码中访问locfrnd 我创建了一个包含2个元素的数组PlaceCollection

place
locfrnd这是一个数组

我尝试访问place并且能够访问它，但locfrnd我收到以下错误

var ctry = $scope.country;
var frnds = [];

angular.forEach($scope.Friend, function (friend) {
    var eachFriend = {
        name: friend
    }
    frnds.push(eachFriend);
});

var record = {
    place: ctry,
    locFrnd: frnds
}

$scope.placeCollection.push(record);

//I am getting object object from the following code
for (var j = 0; j < $scope.placeCollection.length; j++) {
    alert($scope.placeCollection[j].locFrnd);
}

Answer 1

您可以尝试JSON.stringify，如下所示：

var arr = [{place: 'ABC', locFriend: 'XYZ'}, {place: 'abc', locFriend: 'xyz'}];
alert(JSON.stringify(arr));

你的locFrnd是一个数组，当你在数组上发出警报时，你会得到[objcet Object]。

Answer 2

这也应该有用

   for (var j = 0; j < $scope.placeCollection.length; j++) {
        var locFrndArray = $scope.placeCollection[j].locFrnd;
            locFrndArray.map(function(item){
                                            alert(item.name })
                                         }
}
