jsTree拖放按类限制文件夹 [英] jsTree drag and drop restrict folders by class

问题描述

如何通过类名class ="locked"锁定文件夹上的拖动功能? 同时锁定其他文件夹，将其拖放到该文件夹​​中class ="locked".

How can you lock the drag function on a folder by class name class="locked"? And on the same time lock other folders to be draged into this folder class="locked".

我想要一个同时具有拖放功能和上下文菜单的设置. 如果该节点的类名称为"locked"，那么我只想禁用对contextmenu的编辑，并且既不能将其拖到该文件夹​​中，也可以将该文件夹拖到新位置.

I want a setup where I have both drag and drop, and contextmenu. If the node has the class name "locked" I just want to disable editing for both contextmenu and possibility to drag into this folder or drag this folder to new location.

Tnx

推荐答案

使用CRRM插件结合.get_move()的核心文档找到了一种方法.

Found a way by using the CRRM plugin combined with core documentation for .get_move().

.o"是要移动的节点，.r"是移动中的参考节点.

".o" is the node being moved, and ".r" is the reference node in the move.

这是我的代码:

"crrm" : {
            "move" : {
                "default_position" : "first",
                "check_move" : function (m) {  
                    return (m.o.hasClass("locked") || m.r.hasClass("locked")) ? false : true;  
                }
            }
        }
