Problem description:

I recently encountered a problem using jstree. When the parent node is selected, the disabled child nodes will also be selected as follows

Solution:

1. Upgrade jstree to the latest version, v3.3.4 and above You can

2. Modify the checkbox plug-in configuration and set cascade_to_disabled to false (note: the configuration script needs to be placed after jstree.min.js)

<script src="./../../dist/jstree.min.js"></script>
<script>
$.jstree.defaults.checkbox = {
      visible: true,
      three_state: true,
      whole_node: true,
      keep_selected_style: true,
      cascade: &#39;&#39;,
      tie_selection: true,
      /**
      * This setting controls if cascading down affects disabled checkboxes
      * @name $.jstree.defaults.checkbox.cascade_to_disabled
      * @plugin checkbox
      */
      cascade_to_disabled : false,
      cascade_to_hidden : true
};
 
 
$(&#39;#data&#39;).jstree({
    &#39;core&#39; : {
      &#39;data&#39; : [
        { "text" : "Root node", "children" : [
            { "text" : "Child node 1", "state": { "disabled": true } },
            { "text" : "Child node 2" },
            { "text" : "Child node 3" },
            { "text" : "Child node 4" },
            { "text" : "Child node 5" },
            { "text" : "Child node 6" }
        ]}
      ]
    }
    ,"plugins" : [ "checkbox" ]
  });
</script>

After modification, when the parent node is selected, the child node will skip the disabled child node as follows:
