Question

从angular forEach返回值时，我遇到了一些问题。

这是我的数据：

vm.memberDetails={
    "member": [
        {
            "firstName": "HARRY UTTWO",
            "lastName": "POTTER",
        }
    ],
    "User": [
        {
            "memberId": 7586671,
            "customerId": 7586671,
            "customerStatus": "T",
            "firstName": "HEMOOINE",
            "lastName": "POTTER",
        },
    ]
}

vm.mockData = {
    "data": [{
        "memberNo": 7586671,
        "suffix": "A"
    }]
}

这里我需要比较memberId并从第一个数据中获取名称。我使用了angular.forEach，但是对于名称我需要使用
vm.memberDetails.User[0].firstName，但仅返回带有循环的值。

控制器：

angular.forEach(vm.memberDetails.User, function (value1,key1) {
    angular.forEach(vm.mockData, function (value2,key2) {
        if (value1.memberId === value2.memberNo) {

            vm.some= vm.memberDetails.User[0].firstName;
        }
    });
});
return vm.some;

任何帮助将不胜感激。谢谢。

您似乎需要从vm.mockData中获取数据数组，因此将行angular.forEach(vm.mockData, function (value2,key2) { 更改为 angular.forEach(vm.mockData.data, function (value2,key2) {

angular.forEach(vm.memberDetails.User, function (value1,key1) {
    angular.forEach(vm.mockData.data, function (value2,key2) {
        if (value1.memberId === value2.memberNo) {
            vm.some= vm.memberDetails.User[0].firstName;
        }
    });
});
return vm.some;
