Question

这是我的保存功能，我需要在localstorage中保存为数组.Below代码显示已尝试过的内容？我怎么解决这个问题？在我做错误的地方，相同的值会附加在所有数组中

有人可以帮助解决这个问题吗？

$scope.savealbum = function() {

            var AlbumTitle = $("#AlbumTitle").val(); // 345
            var AlbumDescription = $("#AlbumDescription").val(); // 345
            var ImageName = $("#ImageName").val(); // 345
            var youtube1 = $scope.youtubelink1; // 345
            var youtube2 = $scope.youtubelink2; // 345
            var videocomment1 = $scope.videocomment1; // 345
            var videocomment2 = $scope.videocomment2; // 345
            var imagearray = $scope.imagearray; // 345


             var Album = {
                 album_desc: AlbumDescription,
                 id: 1,
                 album_title: AlbumTitle,                
                 ImageName: ImageName,
                 youtube1: youtube1,
                 youtube2: youtube2,
                 videocomment1: videocomment1,
                 videocomment2: videocomment2,
                 album_pics: []
             };



             // if (JSON.parse(localStorage.getItem('album')!="")) {
             var newPics = {
                 "media_type": imagearray['_file']['type'],
                 "last_modified_date": imagearray['_file']['lastModified'],
                 "thumnail_pic_loc": imagearray['_file']['name'],
                 "large_pic_loc": imagearray['_file']['name'],
                 "filter_type": imagearray['_file']['type'],
                 "pic_id": "d5bd"
             };

             Album.album_pics.push(newPics);
             // }

            $scope.albarr = [];
            $scope.albarr.push(Album);

            if (!JSON.parse(localStorage.getItem('album'))) {
                localStorage.setItem('album', JSON.stringify($scope.albarr));               
            } else {

                $scope.getalb=JSON.parse(localStorage.getItem('album'));
                for(irf in $scope.getalb) {
                    console.log('$scope.getalb');
                    console.log($scope.getalb[irf]);


                        $scope.album.album_desc = AlbumDescription;
                         //$scope.album.id= val['id']+1;
                        $scope.album.album_title= AlbumTitle;                
                         $scope.album.ImageName= ImageName;
                         $scope.album.youtube1= youtube1;
                         $scope.album.youtube2= youtube2;
                         $scope.album.videocomment1= videocomment1;
                         $scope.album.videocomment2= videocomment2;                      
                         $scope.album.album_pics= [{
                             "media_type": imagearray['_file']['type'],
                             "last_modified_date": imagearray['_file']['lastModified'],
                             "thumnail_pic_loc": imagearray['_file']['name'],
                             "large_pic_loc": imagearray['_file']['name'],
                             "filter_type": imagearray['_file']['type'],
                             "pic_id": "d5bd"
                         }];


                    $scope.getalb[irf]=$scope.album;
                    $scope.albarr.push($scope.getalb[irf]);
                }
                console.log($scope.albarr);
            localStorage.setItem('album', JSON.stringify($scope.albarr));
            //$route.reload();


            }


        }

现在结果

[{
    "album_desc": "test2",
    "id": 1,
    "album_title": "Test1",
    "ImageName": "Penguins.jpg",
    "album_pics": [{
        "media_type": "image/jpeg",
        "last_modified_date": 1247549551000,
        "thumnail_pic_loc": "Penguins.jpg",
        "large_pic_loc": "Penguins.jpg",
        "filter_type": "image/jpeg",
        "pic_id": "d5bd"
    }]
}, {
    "album_title": "Test1",
    "album_desc": "test2",
    "ImageName": "Penguins.jpg",
    "album_pics": [{
        "media_type": "image/jpeg",
        "last_modified_date": 1247549551000,
        "thumnail_pic_loc": "Penguins.jpg",
        "large_pic_loc": "Penguins.jpg",
        "filter_type": "image/jpeg",
        "pic_id": "d5bd"
    }]
}]

我的预期输出

    [{
    "album_desc": "test1",
    "id": 1,
    "album_title": "Test1",
    "ImageName": "Light.jpg",
    "album_pics": [{
        "media_type": "image/jpeg",
        "last_modified_date": 1247549551000,
        "thumnail_pic_loc": "Light.jpg",
        "large_pic_loc": "Light.jpg",
        "filter_type": "image/jpeg",
        "pic_id": "d5bd"
    }]
}, {
    "album_title": "Test1",
    "album_desc": "test2",
    "ImageName": "Penguins.jpg",
    "album_pics": [{
        "media_type": "image/jpeg",
        "last_modified_date": 1247549551000,
        "thumnail_pic_loc": "Penguins.jpg",
        "large_pic_loc": "Penguins.jpg",
        "filter_type": "image/jpeg",
        "pic_id": "d5bd"
    }]
}]

如果我了解您的问题，您只想在每次点击表单时在localStorage数组中添加新相册？而且您的代码目前每次都存储在相同的专辑中。

对于这个简单的操作，您的代码非常复杂！我不明白你的“for”循环的目标？

对我来说，这是解决方案：

$scope.getalb = JSON.parse(localStorage.getItem('album'));

if (!JSON.parse($scope.getalb)) {
  localStorage.setItem('album', JSON.stringify($scope.albarr));
} else {
  $scope.getalb.push(Album);
  localStorage.setItem('album', JSON.stringify($scope.getalb));
}

如何在角度js中附加数组中的给定值
