asp.net-mvc - 在 Kendo TreeView 中获取所选节点的 id

Question

我有这个 Controller 方法将树项发送到 View 中的树:

private IEnumerable<TreeViewItemModel> GetTrees()
{
    InstallationPlaceModel ipm = new InstallationPlaceModel();
    var gipo = ipm.getRootInstallationPlaces();
    List<TreeViewItemModel> fullTree = new List<TreeViewItemModel>();

    foreach (wsInstallationPlace.installationPlaceOutput father in gipo.installationPlaces)
    {
        var gipo2 = ipm.getChildInstallationPlaces(father.installationPlace.id);
        List<TreeViewItemModel> childTree = new List<TreeViewItemModel>();

        foreach (wsInstallationPlace.installationPlaceOutput child in gipo2.installationPlaces)
        {
            TreeViewItemModel childTreeItem = new TreeViewItemModel
            {
                Text = child.installationPlace.mediumDescription,
                Id = child.installationPlace.id
            };          
            childTree.Add(childTreeItem);
        }
        TreeViewItemModel fatherTreeItem = new TreeViewItemModel
        {
            Text = father.installationPlace.mediumDescription,
            Id = father.installationPlace.id,
            Items = childTree
        };
        fullTree.Add(fatherTreeItem);
    }
    ViewBag.mytree = fullTree;
    return fullTree;
}

这是 Kendo Treeview :

@(Html.Kendo().TreeView()
    .Name("treeview")
    .DragAndDrop(true)
    .Events(e => e.Select("onSelect"))
    .BindTo((IEnumerable<TreeViewItemModel>)ViewBag.mytree)
)

这个函数来处理树节点的选择:

function onSelect(e) {
    alert(this.text(e.node));
}

选择节点后，会显示带有节点文本的警报。我想显示节点的 id。我试过了:

function onSelect(e) {
    alert(this.id(e.node));
}

但没有运气。正如您在 Controller 方法中看到的，我正在填充 text 和 id 属性，但我只能访问文本。有什么帮助吗？

要获取所选节点的 id ，您应该使用 $(e.node).data("id") 。

function onSelect(e) {
    alert($(e.node).data("id"));
}
