jstree contextmenu创建文件/文件夹功能

Question

我试图让用户创建文件或文件夹。因此，当他们右键单击菜单时，上下文菜单将显示： 创建=> 文件 文件夹

这部分工作正常，问题在于附加到每个上下文菜单的功能。此时单击“文件”或“文件夹”会调用： this.create(obj); 如何指定类型？我尝试过 obj.attr("rel","type","folder")，我尝试过 obj.rslt.rel 和许多其他方法，但我'我只是在黑暗中拍摄，哈哈。我已经阅读了文档，布局很好，但对于解释对象的属性毫无用处。

下面是上下文菜单、类型插件和创建节点的绑定的代码。

    fma_jstree = $("#archive")
.bind("before.jstree", function (e, data) {
    $("#alog").append(data.func + "<br />");
})
.jstree({

    "plugins" : [
    "themes","json_data","ui","crrm","cookies","dnd","search","types","hotkeys","contextmenu"
    //"themes","json_data","ui","crrm","cookies","dnd","search","types","contextmenu"
    ],

    "contextmenu" : {
        items : { // Could be a function that should return an object like this one

指定要创建的节点类型的代码是：

this.create(obj, "last", {"attr" : {"rel" : "default"}});

所以现在 contextmenu 插件的代码如下所示：

        "contextmenu" : {
        items : { // Could be a function that should return an object like this one
            "create" : {
                "separator_before"  : false,
                "separator_after"   : true,
                "label"             : "Create",
                "action"            : false,
                "submenu" :{
                    "create_file" : {
                        "seperator_before" : false,
                        "seperator_after" : false,
                        "label" : "File",
                        action : function (obj) {
                            this.create(obj, "last", {"attr" : {"rel" : "default"}});
                        }
                    },
                    "create_folder" : {
                        "seperator_before" : false,
                        "seperator_after" : false,
                        "label" : "Folder",
                        action : function (obj) {                               
                            this.create(obj, "last", {"attr" : { "rel" : "folder"}});
                        }
                    }
                }
            }
        }
    },
