Question

这是我的代码，它应该在使用ctrl键时阻止节点复制，但它仍然允许复制并且不会阻止它。

我根据文档使用"copy_modifier" : false - 任何想法为什么它不起作用？

我正在使用几天前通过网站上的大下载按钮下载的稳定版"jsTree 1.0-rc3"。

$(function () {

    $("#jsTree")
        .jstree({
            "plugins" : ["themes","html_data","ui","crrm","hotkeys","types","dnd","contextmenu"], contextmenu: {items: customMenu}
            //"core" : { "initially_open" : [ "node_root" ] }
        ,"types" : {
            "valid_children" : [ "group","unknowngroup" ],
            "types" : {
                "group" : {
                    "valid_children" : ["event"],
                    "start_drag" : false,
                    "move_node" : false,
                    "delete_node" : false,
                    "remove" : false,
                    "icon" : {
                        "image" : "layout/img/folder.png"
                    },
                },
                "unknowngroup" : {

已修复 - 正如您所见，“dnd”实际上位于“类型”范围内。卫生署！ - 如果允许，将接受。

jsTree copy_modifier：false - 不阻止节点复制！
