            @foreach (var treeNode in Model)
            {
                <!-- in this example the tree is populated from inline HTML -->
                <ul>
                    <li id="@treeNode.Id">@treeNode.NodeName
                        @if(treeNode.ChildNode.Count() > 0)

推荐答案

终于找到了解决我问题的方法.我将答案发布在这里，以供将来任何人参考.

Finally found the solution to my problem. I am posting the answer here for anyone's future reference.

我所做的是在脚本块中添加了以下脚本.

What i did is added the following script in my script block.

    $('#jstree').on('changed.jstree', function (e, data) {
        var i, j, r = [];
        for (i = 0, j = data.selected.length; i < j; i++) {
            r.push(data.instance.get_node(data.selected[i]).text);
        }
        $('#resultText').html('Selected: ' + r.join(', '));
    }).jstree();

这给了我想要的输出.

This given me the desired output.
