jstree启用节点及其子节点

I am using:

我在用：

jstree("disable_node", "#" + NodeID);

to disable a node in jstree. and using:

禁用jstree中的节点。和使用：

jstree("enable_node", "#" + NodeID);

to enable a node.

启用节点。

Is there a simple way to disable/enable a node and it's children?

是否有一种简单的方法可以禁用/启用节点及其子节点？

thank you

谢谢

You can do it with the code as below. Check demo - Fiddle.

您可以使用以下代码执行此操作。检查演示 - 小提琴。

Write a recursive function to iterate multi-level structures

编写递归函数来迭代多级结构

function changeStatus(node_id, changeTo) {
    var node = $("#tree").jstree().get_node(node_id);
    if (changeTo === 'enable') {
        $("#tree").jstree().enable_node(node);
        node.children.forEach(function(child_id) {
            changeStatus(child_id, changeTo);
        })
    } else {
        $("#tree").jstree().disable_node(node);
        node.children.forEach(function(child_id) {
            changeStatus(child_id, changeTo);
        })
    }
}

Call function depending on what you need

根据您的需要调用函数
```
changeStatus(NodeID, 'enable');
```
or

要么
```
changeStatus(NodeID, 'disable');
```

I write a simple JS function based on jstree documentation about get_node function and jstree JSON data format that enable/disable the input node and all it's child in any level:

我编写了一个基于jstree文档的简单JS函数，该文档关于get_node函数和jstree JSON数据格式，它启用/禁用输入节点及其在任何级别的所有子节点：

    NodeToggleEnable = function (node_id, enable) {
        var tree = $("#jstree-locations");
        var sub_tree = [node_id.toString()];
        var index = 0;
    while (index < children.length) {
        var child = tree.jstree("get_node", "#" + children[index]).children;
        sub_tree = sub_tree.concat(child);
        if (enable == false)
            tree.jstree("disable_node", "#" + sub_tree[index]);
        else
            tree.jstree("enable_node", "#" + sub_tree[index]);
        index++;
    }
}

this function uses children(array of strings or objects) property of node that selected by get_node function.

此函数使用由get_node函数选择的节点的子节点（字符串或对象的数组）属性。
