我遇到一个问题，当我尝试选择多个设备并将它们添加到一个组时，所选设备的数组（$ scope.deviceIDs.push）没有获取值。任何人都可以看到问题或建议不同的方法。我使用http://www.dotnetawesome.com/2015/12/multiselect-dropdown-with-checkbox-in-angularjs.html作为我构建的服务的模板。
这是角度代码。
var MyApp = angular.module('MyApp', ['ui.bootstrap', 'angularjs-dropdown-multiselect']);
MyApp.controller('GroupsController', ['GroupsService', '$scope', '$log', '$uibModal',
function (GroupsService, $scope, $log, $uibModal) {
$scope.groupSelected = [];
$scope.location = '';
$scope.groupguid = '';
$scope.newGroupName = '';
$scope.devicesNotinGroup = [];
$scope.newGroupAddMember = 'false';
$scope.isCollapsed = false;
$scope.groupSelected.GroupID = 0;
$scope.SelectedDevices = [];
$scope.deviceIDs = [];
$scope.dropdownSetting = {
scrollableHeight: '200px',
scrollable: true,
enableSearch: true
}
// Populate Jobs
GroupsService.GetDeviceList().then(function (d) {
$scope.GroupList = d.data;
console.log(d.data)
}, function (error) {
alert('Error!');
});
$scope.showChilds = function (item) {
$scope.grouplist = [];
item.active = !item.active;
console.log("here item=" + item.GroupName + " active=" + item.GroupName.active);
grouplist = item.SubGroup;
};
$scope.showInfoForGroup = function (item) {
console.log("item = " + item + "Count = " + item.DeviceCount);
GroupsService.GetGroupDeviceInformation(item).then(function (d) {
$scope.groupSelected = d.data.devicegroupitem;
//$scope.devicesNotinGroup = d.data.devicesnotingroup;
angular.forEach(d.data.devicesnotingroup, function (value, index) {
$scope.devicesNotinGroup.push({ label: value.HostName, id: value.HostName });
});
//console.log($scope.devicesNotinGroup)
})
}, function (error) {
console.log("item = " +item + "Count = " + groupSelected.DeviceCount);
};
$scope.DeleteDeviceFromGroup = function (deviceguid, groupguid ) {
console.log("DeviceGuid = " + deviceguid + " GroupGuid = " + groupguid);
GroupsService.DeleteDeviceFromList(deviceguid, groupguid).then(function (d) {
$scope.groupSelected = d.data;
})
}
$scope.AddDeviceToGroup = function (hostname, groupguid) {
GroupsService.AddDeviceToGroup(hostname, groupguid).then(function (d) {
$scope.showInfoForGroup(dt.guid);
//$scope.groupSelected = d.data.devicegroupitem;
//$scope.devicesNotinGroup = d.data.devicesnotingroup;
$scope.newGroupAddMember = 'false';
})
}
$scope.SubmitMultipleDevices = function (groupguid){
$scope.deviceIDs = [];
console.log($scope.SelectedDevices);
angular.forEach($scope.SelectedDevices = function (value) {
$scope.deviceIDs.push({ dname: value.HostName, dguid: groupguid } );
});
console.log('device ids ');
console.log($scope.deviceIDs);
var data = { deviceIDs: deviceIDs };
console.log(data);
angular.toJson(data);
GroupsService.SubmitMultiDevicesToGroup(data)
.success(function () {
})
.error(function (error) {
});
}
$scope.CreateGroup = function (groupID, groupName, newGroupAddMember) {
angular.isUndefinedOrNull = function (groupID) {
return angular.isUndefined(groupID) || groupID === null
}
$scope.GroupList = '';
console.log("check value equals" + groupID)
GroupsService.CreateSubGroup(groupID, groupName, newGroupAddMember).then(function (d) {
$scope.GroupList = d.data;
$scope.newGroupName = '';
$scope.newGroupAddMember = false;
})
}
$scope.DeleteGroup = function (groupID) {
$scope.GroupList = '';
GroupsService.DeleteSubGroup(groupID).then(function (d){
$scope.GroupList = d.data;
$scope.newGroupName = '';
})
}
}])
MyApp.factory('GroupsService', function ($http) { // explained about factory in Part2
var fac = {};
fac.GetDeviceList = function () {
return $http.get('/DeviceGroups/getgrouptree')
}
fac.GetGroupDeviceInformation = function (guid) {
return $http.get('/DeviceGroups/GetGroupDeviceInfo?groupguid=' + guid)
}
fac.DeleteDeviceFromList = function (deviceguid, groupguid) {
return $http.get('/DeviceGroups/DeleteDeviceFromGroup?deviceguid='+ deviceguid + "&groupguid=" + groupguid)
}
fac.AddDeviceToGroup = function (hostname, groupguid) {
return $http.get('/DeviceGroups/AddDeviceToGroup?hostname=' + hostname + "&groupguid=" + groupguid)
}
fac.CreateSubGroup = function (groupID, groupName, newGroupAddMember) {
return $http.get('/DeviceGroups/CreateGroup?GroupID=' + groupID + "&groupName=" + groupName + "&AddMember=" + newGroupAddMember)
}
fac.DeleteSubGroup = function (groupID) {
return $http.get('/DeviceGroups/DeleteGroup?GroupID=' + groupID)

fac.SubmitMultiDevicesToGroup = function (data) {

答案 0 :(得分：2)
你的forEach循环不正确。
angular.forEach($scope.SelectedDevices = function (value) {
$scope.deviceIDs.push({ dname: value.HostName, dguid: groupguid } );
});
应该是：
angular.forEach($scope.SelectedDevices, function (value) {
$scope.deviceIDs.push({ dname: value.HostName, dguid: value.groupguid } );
});
