Question

我有一个数组格式的数据，如下所示：

    Array
    (
        [0] => Array
            (
                [@attributes] => Array
                    (
                        [Domain] => domain1.com
                        [Available] => true
                        [ErrorNo] => 0
                        [Description] => 
                        [IsPremiumName] => false
                        [PremiumRegistrationPrice] => 0
                        [PremiumRenewalPrice] => 0
                        [PremiumRestorePrice] => 0
                        [PremiumTransferPrice] => 0
                        [IcannFee] => 0
                        [EapFee] => 0
                    )

            )

        [1] => Array
            (
                [@attributes] => Array
                    (
                        [Domain] => domain2.com
                        [Available] => true
                        [ErrorNo] => 0
                        [Description] => 
                        [IsPremiumName] => false
                        [PremiumRegistrationPrice] => 0
                        [PremiumRenewalPrice] => 0
                        [PremiumRestorePrice] => 0
                        [PremiumTransferPrice] => 0
                        [IcannFee] => 0
                        [EapFee] => 0
                    )

            )

        [2] => Array
            (
                [@attributes] => Array
                    (
                        [Domain] => domain3.com
                        [Available] => true
                        [ErrorNo] => 0
                        [Description] => 
                        [IsPremiumName] => false
                        [PremiumRegistrationPrice] => 0
                        [PremiumRenewalPrice] => 0
                        [PremiumRestorePrice] => 0
                        [PremiumTransferPrice] => 0
                        [IcannFee] => 0
                        [EapFee] => 0
                    )

            )
)

我想在Laravel的刀片视图中使用这些数据所以我这样做了：

@foreach($results as $result => $datas)
                        @foreach($datas as $data => $attributes )
                            @foreach($attributes as $attribute => $value)
                                <tr>
                                    @foreach($attribute["Domain"] as $domain)
                                    <td>{{ $domain }}</td>
                                    @endforeach
                                    <td>.COM</td>
                                    <td>.NET</td>
                                    <td>.ORG</td>
                                </tr>
                            @endforeach
                        @endforeach
                    @endforeach

但当我使用它时：{{ $attribute['Domain'] }}它说：

非法字符串偏移......

当我使用它时：{{ $attribute->Domain }}它说

尝试获取非对象的属性......

我不知道我还应该尝试什么！请帮我。谢谢。
P.S：我知道，这里没有必要使用四个foreach。应该有更好的方法来做到这一点。

如果public partial class MainWindow : Window { public MainWindow { InitializeComponent(); this.PreviewKeyDown += (s, e) => { if(e.Key == Key.F4) SelectRowByIndex(dataGridProducts, dataGridProducts.Items.Count - 1); }; //populate DataGrid etc... } private static void SelectRowByIndex(DataGrid dataGrid, int rowIndex) { if (!dataGrid.SelectionUnit.Equals(DataGridSelectionUnit.FullRow)) throw new ArgumentException("The SelectionUnit of the DataGrid must be set to FullRow."); if (rowIndex < 0 || rowIndex > (dataGrid.Items.Count - 1)) throw new ArgumentException(string.Format("{0} is an invalid row index.", rowIndex)); dataGrid.SelectedItems.Clear(); object item = dataGrid.Items[rowIndex]; dataGrid.SelectedItem = item; DataGridRow row = dataGrid.ItemContainerGenerator.ContainerFromIndex(rowIndex) as DataGridRow; if (row == null) { /* bring the data item (Product object) into view * in case it has been virtualized away */ dataGrid.ScrollIntoView(item); row = dataGrid.ItemContainerGenerator.ContainerFromIndex(rowIndex) as DataGridRow; } if (row != null) { DataGridCell cell = GetCell(dataGrid, row, 0); if (cell != null) cell.Focus(); } } private static DataGridCell GetCell(DataGrid dataGrid, DataGridRow rowContainer, int column) { if (rowContainer != null) { System.Windows.Controls.Primitives.DataGridCellsPresenter presenter = FindVisualChild<System.Windows.Controls.Primitives.DataGridCellsPresenter>(rowContainer); if (presenter == null) { /* if the row has been virtualized away, call its ApplyTemplate() method * to build its visual tree in order for the DataGridCellsPresenter * and the DataGridCells to be created */ rowContainer.ApplyTemplate(); presenter = FindVisualChild<System.Windows.Controls.Primitives.DataGridCellsPresenter>(rowContainer); } if (presenter != null) { DataGridCell cell = presenter.ItemContainerGenerator.ContainerFromIndex(column) as DataGridCell; if (cell == null) { /* bring the column into view * in case it has been virtualized away */ dataGrid.ScrollIntoView(rowContainer, dataGrid.Columns[column]); cell = presenter.ItemContainerGenerator.ContainerFromIndex(column) as DataGridCell; } return cell; } } return null; } private static T FindVisualChild<T>(DependencyObject obj) where T : DependencyObject { for (int i = 0; i < VisualTreeHelper.GetChildrenCount(obj); i++) { DependencyObject child = VisualTreeHelper.GetChild(obj, i); if (child != null && child is T) return (T)child; else { T childOfChild = FindVisualChild<T>(child); if (childOfChild != null) return childOfChild; } } return null; } }是提供的数组，那么您可以将代码简化为：

$results
