css - 如何将以下 CSS 仅应用于 Kendo Treeview 的父节点？

Question

我有这个 CSS 类:

.relationshipsTree 
{
    display: inline;
    font-size: 10pt;
    text-decoration: none;
    /*cursor: hand;*/
    overflow: hidden;
    overflow-x: hidden;
    overflow-y: hidden;
    filter: none;
    font-weight: bold;
    color: green;
    background-color: transparent;
}

我想在这个 Kendo Tree View 的父节点上使用它:

<div id="relationshipsTree"></div>

我该怎么做？

编辑 -

这是我用来创建树的 .js 文件。我补充说:

$('#relationshipsTree').parent().addClass('relationshipsTree');

然而，根据此处的回答，它仍然无法正常工作。

整个文件:

function CreateRelationshipsTree()
{
    var primaryContactId = 671;
    var personOrCompany = 'C';
    var rootMemberId = 0;

    var data = new kendo.data.HierarchicalDataSource({
        transport: {
            read: {
                url: "../api/relationships?primaryContactId=" + primaryContactId + "&personOrCompany=" + personOrCompany + "&rootMemberId=" + rootMemberId,
                contentType: "application/json"
            }
        },
        schema: {
            model: {
                hasChildren: "hasChildren",
                children: "Items"
            }
        }
    });

    $("#relationshipsTree").kendoTreeView({
        dataSource: data,
        loadOnDemand: true,
        dataUrlField: "LinksTo",
        dataTextField: ["Name", "Name"],
        select: treeviewSelect
    });

    function treeviewSelect(e) {
        var node = this.dataItem(e.node);
        window.open(node.NotificationLink, "_self");
    }

    $('#relationshipsTree').parent().addClass('relationshipsTree');
}

function RefreshProjectTree() {
    var treeView = $("#relationshipsTree").data("kendoTreeView");
    treeView.dataSource.read();
}

已更新

我发现我误解了你的问题。我认为您想在 Treeview 中选择父节点时选择 DOM 父元素。这是我更新的答案。

稍微简化您的处理程序:

function treeviewSelect(e) {
  $('#relationshipsTree div').removeClass('relationshipsTree');
  $(e.node).parents('li').first().children('div').addClass('relationshipsTree');
  var node = this.dataItem(e.node);
  window.open(node.NotificationLink, "_self");
  
}
