How to handle forms in Vue
Article Introduction：There are three key points to be mastered when processing Vue forms: 1. Use v-model to achieve two-way binding and synchronize form data; 2. Implement verification logic to ensure input compliance; 3. Control the submission behavior and process requests and status feedback. In Vue, form elements such as input boxes, check boxes, etc. can be bound to data attributes through v-model, such as automatically synchronizing user input; for multiple selection scenarios of check boxes, the binding field should be initialized into an array to correctly store multiple selected values. Form verification can be implemented through custom functions or third-party libraries. Common practices include checking whether the field is empty, using a regular verification format, and displaying prompt information when errors are wrong; for example, writing a validateForm method to return the error message object of each field. You should use it when submitting

HTML5 form validation custom error messages
Article Introduction：How to set custom error message with JavaScript? 1. Use the setCustomValidity() method combined with native form verification, and set prompts for specific input conditions through JavaScript. For example, when the username is less than 3 characters, it prompts "the username needs at least 3 characters"; 2. Combine HTML attributes (such as required, pattern) and JS supplementary verification, and return targeted prompts according to different reasons for verification failure. For example, when the email format is inconsistent, "the email must end with @example.com"; 3. Note that after each verification, you need to call setCustomValidity('') to clear the error message and select the appropriate event (input and i)

Utilizing New HTML5 Input Types for Enhanced Forms
Article Introduction：The new HTML5 input type improves the form experience, the main methods include: 1. Use email and url types to realize automatic format verification and optimize the mobile keyboard; 2. Use number and range to process numerical input, which are suitable for accurate values ??and sliding selection respectively; 3. Use date series types to call the native date selector to improve time input efficiency. These features reduce the burden of front-end verification, but basic verification still needs to be supplemented by the server. Some types need to be combined with JS libraries to ensure compatibility on old devices.

Implementing Custom HTML5 Input Pattern Validation
Article Introduction：The pattern attribute is a regular expression tool used for form verification in HTML5. It allows developers to restrict input formats through regularity. 1. It is valid only for text class input; 2. Regularity does not require anchor points, and case and escape need to be manually processed; 3. Common formats such as mobile phone numbers and passwords have corresponding expressions; 4. The browser compatibility is good but the prompt style is not uniform; 5. Prompt information can be provided with the title attribute; 6. Some mobile environments need to be tested or supplemented with JS verification. When using it, you should adjust the rules according to business needs and pay attention to their limitations. If necessary, combine JavaScript to implement more complex verification logic.
