How to deal with the problem of editing, saving and canceling list items encountered in Vue development

In Vue development, we often encounter situations where we need to edit, save and cancel list items. Such operations have a great impact on user experience and convenience during development. This article will introduce a common method to deal with the issue of editing, saving and canceling list items.

1. Add an editing status identifier to the list item

In Vue, you can add a status identifier to the list item to indicate whether the item is in the editing state. You can use a variable, such as isEditing, to record the switching of editing status. When the list items are displayed, different display styles can be displayed based on the value of isEditing. When the edit button is clicked, isEditing is set to true, and the list item enters the editing state; when the save button is clicked, isEditing is set to false, and the list item ends the editing state; when the cancel button is clicked, isEditing is set to false, and the list item Restore to previous state.

2. Use computed properties to manage the data of list items

In Vue, you can use the computed properties to manage the data of list items. In this way, you can achieve both editing and non-editing. Synchronous update of data in editing state. You can define a computed attribute for each list item, such as editedItem to obtain the editing data of the item. When isEditing is true, the computed attribute value will be updated to the edited data in real time; when isEditing is false, the computed attribute value will be updated to the original data of the list item. This ensures that the data and list items are updated synchronously in the editing state, and the data and list items remain consistent in the non-editing state.

3. Use v-model two-way binding to save editing data

In Vue, you can use the v-model instruction to achieve two-way data binding, and add input boxes or other input components Bind to the computed property. In the editing state, when the input box is modified, the computed attribute will update the editing data in real time; when the save button is clicked, the editing data will be saved to the corresponding list item, and isEditing will be set to false to exit the editing state.

4. Use watch to monitor changes in isEditing and perform operations

In Vue, you can use the watch attribute to monitor changes in variables and perform specific operations when changes occur. You can use watch to monitor changes in isEditing and perform save or cancel operations when isEditing becomes false. When isEditing changes from true to false, it means that the user clicked the save or cancel button. At this time, the corresponding operations can be performed according to the needs, such as saving the edited data to the interface or local storage, or restoring the edited data to the original data.

5. Optimize user experience

In order to improve the user experience, you can disable other interactive operations of list items in the editing state, such as prohibiting the deletion of list items or other operation buttons, to prevent users from accidentally operate. When saving or canceling an operation, you can give the user some prompts, such as popping up a confirmation dialog box to prompt the user to confirm whether to save or cancel. In addition, you can also add some animation effects, such as transition effects, to increase the smoothness of the page and the user's operational perception.

Summary:

Through the above method, the issue of editing, saving and canceling list items can be well handled in Vue development. Add an editing status identifier to the list item, use computed properties to manage the data of the list item, use v-model two-way binding to save the editing data, combine the watch to monitor the change of isEditing, and optimize the user experience, you can make the list item The editing function is more friendly and convenient, improving user experience.

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
