Below I will share with you an article that solves the problem that disabled child nodes are also selected when the parent node is selected in Jstree. It has a good reference value and I hope it will be helpful to everyone.
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: '', 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 }; $('#data').jstree({ 'core' : { 'data' : [ { "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 nodes will skip the disabled child nodes as follows:
The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.

Introduction I know you may find it strange, what exactly does JavaScript, C and browser have to do? They seem to be unrelated, but in fact, they play a very important role in modern web development. Today we will discuss the close connection between these three. Through this article, you will learn how JavaScript runs in the browser, the role of C in the browser engine, and how they work together to drive rendering and interaction of web pages. We all know the relationship between JavaScript and browser. JavaScript is the core language of front-end development. It runs directly in the browser, making web pages vivid and interesting. Have you ever wondered why JavaScr

Node.js excels at efficient I/O, largely thanks to streams. Streams process data incrementally, avoiding memory overload—ideal for large files, network tasks, and real-time applications. Combining streams with TypeScript's type safety creates a powe

The differences in performance and efficiency between Python and JavaScript are mainly reflected in: 1) As an interpreted language, Python runs slowly but has high development efficiency and is suitable for rapid prototype development; 2) JavaScript is limited to single thread in the browser, but multi-threading and asynchronous I/O can be used to improve performance in Node.js, and both have advantages in actual projects.

JavaScript originated in 1995 and was created by Brandon Ike, and realized the language into C. 1.C language provides high performance and system-level programming capabilities for JavaScript. 2. JavaScript's memory management and performance optimization rely on C language. 3. The cross-platform feature of C language helps JavaScript run efficiently on different operating systems.

JavaScript runs in browsers and Node.js environments and relies on the JavaScript engine to parse and execute code. 1) Generate abstract syntax tree (AST) in the parsing stage; 2) convert AST into bytecode or machine code in the compilation stage; 3) execute the compiled code in the execution stage.

The future trends of Python and JavaScript include: 1. Python will consolidate its position in the fields of scientific computing and AI, 2. JavaScript will promote the development of web technology, 3. Cross-platform development will become a hot topic, and 4. Performance optimization will be the focus. Both will continue to expand application scenarios in their respective fields and make more breakthroughs in performance.

Both Python and JavaScript's choices in development environments are important. 1) Python's development environment includes PyCharm, JupyterNotebook and Anaconda, which are suitable for data science and rapid prototyping. 2) The development environment of JavaScript includes Node.js, VSCode and Webpack, which are suitable for front-end and back-end development. Choosing the right tools according to project needs can improve development efficiency and project success rate.

Yes, the engine core of JavaScript is written in C. 1) The C language provides efficient performance and underlying control, which is suitable for the development of JavaScript engine. 2) Taking the V8 engine as an example, its core is written in C, combining the efficiency and object-oriented characteristics of C. 3) The working principle of the JavaScript engine includes parsing, compiling and execution, and the C language plays a key role in these processes.
