Course Introduction：Verifying the validity of form fields can be achieved through 1. HTML5 built-in verification; 2. Manually write verification logic; 3. Real-time feedback combined with event listening. HTML5 provides required, type and other properties to be combined with checkValidity() method to achieve basic verification; complex rules require custom functions, such as password consistency check and regular expression matching mailbox and password format; real-time error prompts are achieved through input or blur event listening, and at the same time, pay attention to preventing the default submission behavior and being compatible with old browsers.

Course Introduction：Best practices for managing forms and validation in Vue applications include using form libraries, staying local, processing real-time feedback, and modular large forms. First, for complex verification, libraries such as Vuelidate or VeeValidate should be used, which provide declarative verification rules, custom validator support, built-in error messages and integration with the UI framework, and improve testability and scalability through separate verification logic; second, small forms should prioritize the use of reactive() or ref() to manage local state to reduce complexity, and share data through props or shared combinable functions if necessary; third, when processing real-time feedback, verification should be triggered when the blur and input events are processed, delay verification should avoid flickering, and when submitting

Course Introduction：Real-time form verification: subtle improvements to enhance user experience Core points: JavaScript can be used to implement real-time form verification, which provides users with instant feedback on input validity, thereby improving user experience and maintaining data integrity, ensuring that only valid data is submitted. HTML5 attributes pattern and required can be used to define the valid input range of form elements. If the browser does not support these properties, its values ??can be used as the basis for JavaScript compatibility populators. The aria-invalid property can be used to indicate whether the field is invalid. This property provides accessibility information and can be used as a CSS hook to visually indicate an invalid field.

Course Introduction：The core methods of handling form submission and verification in Vue include using v-model for data binding, blocking default submission behavior through @submit.prevent, executing verification logic in handleSubmit method, using validateForm method for field checking and recording error information, optionally introducing third-party verification libraries such as Vuelidate to improve verification capabilities, and implementing real-time error prompts in combination with @blur or @input. Through these steps, efficient processing of forms and good user experience can be achieved.

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
