Our operating habit is indeed to use Enter to submit data directly. After some inspection of the project, it was found that the page was not designed well, which caused the browser to regard the logout button as the default button when loading, so the logout button event was triggered as soon as Enter was pressed. Considering a huge project, it is unrealistic to change the page design for this problem. Moreover, the customer requires that the "Save" button event be triggered when the Enter button is pressed when there is a "Save" button, and it is triggered when there is a "Next" button. Events, when there is a "Submit" button, the corresponding events are triggered, etc. If you change the pages one by one, the workload will be staggering. So I considered using js directly in the template header file to trigger the event of the Enter button in the entire site. The following is the corresponding code:
It’s actually quite simple. Just add the above paragraph to the template file, first get the enter event, then get all the buttons on the page, and cycle through the buttons one by one. Does the ID meet your requirements? If yes, trigger the button event. Another problem with the above code is that when buttons with several IDs exist at the same time on your page, all buttons will be triggered. As for how to improve it, it depends on the actual application scenario, and in my project, they will not exist at the same time. These buttons can be used safely.

JavaScript core data types are consistent in browsers and Node.js, but are handled differently from the extra types. 1) The global object is window in the browser and global in Node.js. 2) Node.js' unique Buffer object, used to process binary data. 3) There are also differences in performance and time processing, and the code needs to be adjusted according to the environment.

The main difference between Python and JavaScript is the type system and application scenarios. 1. Python uses dynamic types, suitable for scientific computing and data analysis. 2. JavaScript adopts weak types and is widely used in front-end and full-stack development. The two have their own advantages in asynchronous programming and performance optimization, and should be decided according to project requirements when choosing.

Whether to choose Python or JavaScript depends on the project type: 1) Choose Python for data science and automation tasks; 2) Choose JavaScript for front-end and full-stack development. Python is favored for its powerful library in data processing and automation, while JavaScript is indispensable for its advantages in web interaction and full-stack development.

Python and JavaScript each have their own advantages, and the choice depends on project needs and personal preferences. 1. Python is easy to learn, with concise syntax, suitable for data science and back-end development, but has a slow execution speed. 2. JavaScript is everywhere in front-end development and has strong asynchronous programming capabilities. Node.js makes it suitable for full-stack development, but the syntax may be complex and error-prone.

JavaScript can be used for front-end and back-end development. The front-end enhances the user experience through DOM operations, and the back-end handles server tasks through Node.js. 1. Front-end example: Change the content of the web page text. 2. Backend example: Create a Node.js server.

Choosing Python or JavaScript should be based on career development, learning curve and ecosystem: 1) Career development: Python is suitable for data science and back-end development, while JavaScript is suitable for front-end and full-stack development. 2) Learning curve: Python syntax is concise and suitable for beginners; JavaScript syntax is flexible. 3) Ecosystem: Python has rich scientific computing libraries, and JavaScript has a powerful front-end framework.

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),
