jstree从上下文菜单中删除默认元素 [英] jstree remove default elements from context menu

问题描述

JsTree的contextmenu有问题，我如何从Create菜单，Delete菜单，Rename菜单等上下文菜单中删除默认的元素？我想提供我自己的元素，但默认元素仍然处于上下文菜单中。

 contextmenu：{
items：{
IsimVer：{
label：İsimDeğiştir，
action：function（obj）{this.rename（obj）; } 
，
Ekle：{
label：Ekle，
action：function（obj）{this.create（obj）; } 
}，
Sil：{
label：Sil，
action：function（obj）{this.remove（obj）; } 
} 
} 
  

解决方案

前几天我有这个问题，但还没有决定这是一个错误还是一个功能。这可能与插件的加载顺序有关。

我的工作是从函数返回项目：

 contextmenu：{
items：function（$ node）{
 return {
IsimVer：{
label：İsimDeğiştir，
action：function（obj）{this.rename（obj）; } 
，
Ekle：{
label：Ekle，
action：function（obj）{this.create（obj）; } 
}，
Sil：{
label：Sil，
action：function（obj）{this.remove（obj）; } 
} 
}; 
 
 
 
 
 $ b经过一番搜索之后，似乎默认行为是用于菜单项扩展默认值，所以这是一个特征。不幸的是，文档目前缺乏这方面的细节。
 
I have a problem with JsTree's contextmenu, how can I remove the default elements from the contextmenu like Create, Delete, Rename? I want to provide elements of my own, but the default elements are still at the contextmenu. 
    "contextmenu" : {
                    "items" : {
                        "IsimVer" : {
                            "label" : "İsim Değiştir",
                            "action" : function (obj) { this.rename(obj); }
                        },
                        "Ekle" : {
                            "label" : "Ekle",
                            "action" : function (obj) { this.create(obj); }
                        },
                        "Sil" : {
                            "label" : "Sil",
                            "action" : function (obj) { this.remove(obj); }
                        }
}

解决方案
I had this issue a couple of days ago but haven't yet decided if this is a bug or a feature. It may be related to the order in which the plugins are loaded.

What worked for me was returning the items from a function:
"contextmenu" : {
    "items" : function ($node) {
        return {
            "IsimVer" : {
                "label" : "İsim Değiştir",
                "action" : function (obj) { this.rename(obj); }
            },
            "Ekle" : {
                "label" : "Ekle",
                "action" : function (obj) { this.create(obj); }
            },
            "Sil" : {
                "label" : "Sil",
                "action" : function (obj) { this.remove(obj); }
            }
        };
    }
}
After some searching it seems that the default behaviour is for your menu items to extend the defaults, so this is a feature. Unfortunately the documentation currently lacks the detail on this point.
