我在 Jquery 对话框中呈现了一个由 Fancy Tree 转换的列表。我注意到如果我选择一个子节点并关闭树意味着取消展开其父节点并关闭对话框。当我单击另一个节点时重新打开对话框时，我看到另一个选定的节点将自动展开然后取消展开。

$("#errorCodes").fancytree({
    activeVisible: false, // Make sure, active nodes are visible (expanded).
    aria: false, // Enable WAI-ARIA support.
    autoActivate: false, // Automatically activate a node when it is focused (using keys).
    autoCollapse: false, // Automatically collapse all siblings, when a node is expanded.
    autoScroll: false, // Automatically scroll nodes into visible area.
    clickFolderMode: 3, // 1:activate, 2:expand, 3:activate and expand, 4:activate (dblclick expands)
    checkbox: false, // Show checkboxes.
    debugLevel: 0, // 0:quiet, 1:normal, 2:debug
    disabled: false, // Disable control
    generateIds: false, // Generate id attributes like <span id='fancytree-id-KEY'>
    idPrefix: "ft_", // Used to generate node id´s like <span id='fancytree-id-<key>'>.
    icons: false, // Display node icons.
    keyboard: true, // Support keyboard navigation.
    keyPathSeparator: "/", // Used by node.getKeyPath() and tree.loadKeyPath().
    minExpandLevel: 1, // 1: root node is not collapsible
    selectMode: 1, // 1:single, 2:multi, 3:multi-hier
    tabbable: false, // Whole tree behaves as one single control
    titlesTabbable: false // Node titles can receive keyboard focus
});
errorTree = $("#errorCodes").fancytree("getTree");

$("input[name=searchErrors]").keyup(function (e) {
    var match = $(this).val();
    if (e && e.which === $.ui.keyCode.ESCAPE || $.trim(match) === "") {
        $("button#btnResetSearchErrors").click();
        return;
    }

    var n = errorTree.applyFilter(match);
    $("button#btnResetSearchErrors").attr("disabled", false);
    $("span#matchesErrors").text("(" + n + " Results)");
}).focus();

$("button#btnResetSearchErrors").click(function (e) {
    $("input[name=searchErrors]").val("");
    $("span#matchesErrors").text("");
    errorTree.clearFilter();
}).attr("disabled", true);

$("input#hideModeErrors").change(function (e) {
    errorTree.options.filter.mode = $(this).is(":checked") ? "hide" : "dimm";
    errorTree.clearFilter();
    $("input[name=searchErrors]").keyup();
});

我通过下载最新版本的 FancyTree 2.3.0 解决了这个问题。问题是当单击一个节点并使用检查它时，它曾经成为活动行。因此，如果要扩展另一个根节点，它会自动扩展活动行所在的节点。
