Code to control carriage return event using JS_javascript skills

May 16, 2016 pm 06:10 PM

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:

Copy code The code is as follows:



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 Engines: Comparing Implementations JavaScript Engines: Comparing Implementations Apr 13, 2025 am 12:05 AM

Different JavaScript engines have different effects when parsing and executing JavaScript code, because the implementation principles and optimization strategies of each engine differ. 1. Lexical analysis: convert source code into lexical unit. 2. Grammar analysis: Generate an abstract syntax tree. 3. Optimization and compilation: Generate machine code through the JIT compiler. 4. Execute: Run the machine code. V8 engine optimizes through instant compilation and hidden class, SpiderMonkey uses a type inference system, resulting in different performance performance on the same code.

Python vs. JavaScript: The Learning Curve and Ease of Use Python vs. JavaScript: The Learning Curve and Ease of Use Apr 16, 2025 am 12:12 AM

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

From C/C   to JavaScript: How It All Works From C/C to JavaScript: How It All Works Apr 14, 2025 am 12:05 AM

The shift from C/C to JavaScript requires adapting to dynamic typing, garbage collection and asynchronous programming. 1) C/C is a statically typed language that requires manual memory management, while JavaScript is dynamically typed and garbage collection is automatically processed. 2) C/C needs to be compiled into machine code, while JavaScript is an interpreted language. 3) JavaScript introduces concepts such as closures, prototype chains and Promise, which enhances flexibility and asynchronous programming capabilities.

JavaScript and the Web: Core Functionality and Use Cases JavaScript and the Web: Core Functionality and Use Cases Apr 18, 2025 am 12:19 AM

The main uses of JavaScript in web development include client interaction, form verification and asynchronous communication. 1) Dynamic content update and user interaction through DOM operations; 2) Client verification is carried out before the user submits data to improve the user experience; 3) Refreshless communication with the server is achieved through AJAX technology.

JavaScript in Action: Real-World Examples and Projects JavaScript in Action: Real-World Examples and Projects Apr 19, 2025 am 12:13 AM

JavaScript's application in the real world includes front-end and back-end development. 1) Display front-end applications by building a TODO list application, involving DOM operations and event processing. 2) Build RESTfulAPI through Node.js and Express to demonstrate back-end applications.

Understanding the JavaScript Engine: Implementation Details Understanding the JavaScript Engine: Implementation Details Apr 17, 2025 am 12:05 AM

Understanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.

Python vs. JavaScript: Community, Libraries, and Resources Python vs. JavaScript: Community, Libraries, and Resources Apr 15, 2025 am 12:16 AM

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.

Python vs. JavaScript: Development Environments and Tools Python vs. JavaScript: Development Environments and Tools Apr 26, 2025 am 12:09 AM

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.
