Things to note when using jsp:include tags and First recall the difference between the two (for this article, there is no difference in usage between the two)
jsp:include It is to compile the included.jsp file first, and then include it (compile first, then include)
@include is to include the file first, and then compile it uniformly (include first, then compile)
I want to use Jquery this afternoon Integrate it into the project and find that there will be problems no matter what. The reason is the path problem.
When integrating, my idea is to write a public JSP file, which contains some commonly used js files. Of course, I use the Jquery plug-in here.
But after writing it, I found that the public JSP can be used when tested alone, but JQuery cannot be used on pages containing public JSP pages. At first, I thought it was a loading order problem.
After several tests, the problem was finally discovered.
Due to the large number of project files, the files are not placed in one folder: in the public JSP page, there are
< ;script type="text/javascript" src="js/jquery132min.js">
When calling it, there are:
But this is likely to cause errors.
The reason is that after include, the public JSP is loaded into its own JSP, and the relative position of JQueryr has changed. That is, the public JSP passes the relative position of JQuery to its own JSP, but its own JSP uses itself as the standard, and the Jquery plug-in cannot be found through the path. Simply put, if you use a relative path, the path in the public JSP should be relative to the path of your own jSP.
But this obviously loses the meaning of it being a public JSP, so use absolute paths here:
String tPath = request.getContextPath();
String tBasePath = request.getScheme() "://" request.getServerName() ":" request.getServerPort() tPath "/";
%>
In this way, as long as it is in your own jSP Just introduce public JSP into the page.

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.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
