jQuery asynchronously loads data and adds events example_jquery
A few months ago, I was involved in a tree bar in a project, and after looking at a lot of plug-ins, I found it a bit troublesome, so I wrote one myself, and problems started to arise every time I kept doing it.
At that time, the project was controlled through a tree bar. The administrator could dynamically generate a tree bar for the data from the database to add, delete, modify and check. However, using the $(".XX").click(); method That's not possible.
1. I used jq1.4.3 before, and you can use the live() method in jq1.7 to achieve this function
$(‘#div').live(‘click',function(){ //do stuff });
However, the live method also has unsupported events, such as: toggle event. When encountering this situation, you can add a click event to it, and then simulate a click trigger event and it will be ok
$('a').live('click',function(){ $(this).toggle(function(){ alert("q11"); // alert($(this).attr("id")); $(this).parent().children('ul').show(); },function(){ $(this).parent().children('ul').hide(); }); $(this).trigger('click'); /** 之前绑定的click事件,只有点击了才会触发toggle事件,所以就给他加上模拟点击事件,不需要点击直接出发 **/ });
2. For jq1.7 and above, use the on method. The first attribute is the event, the second is the selector, and the third is the execution method
$(document).on("click","#d1",function(){ alert("bbbbb"); });

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.

JavaScript is at the heart of modern websites because it enhances the interactivity and dynamicity of web pages. 1) It allows to change content without refreshing the page, 2) manipulate web pages through DOMAPI, 3) support complex interactive effects such as animation and drag-and-drop, 4) optimize performance and best practices to improve user experience.
