1. General

page:transition:finish The hook is called when the page transition effect is complete, especially when the page'sonAfterLeave
After the event is triggered. It allows the developer to perform some necessary cleanup, state reset, or other subsequent actions.

2. Detailed description of page:transition:finish hooks

2.1 Definition and role of hooks

page:transition:finish The main features include:

  • Cleaning up transition-related states
  • Keeping statistics or records
  • Update UI or Status

2.2 Timing of calls

  • Execution environment: Executed on the client side only.
  • timing of mounting: The browser calls this hook when the transition on the current page is complete, meaning that the content of the page has been fully rendered and animated.

2.3 Return Values and Exception Handling

Hooks have no return value. Any exceptions within the hook should be handled appropriately to ensure that they do not result in subsequent page state errors.

3. Specific examples of use

3.1 Basic Usage Examples

Suppose we want to perform some logic after the page transition is complete, such as updating the page title:

// plugins/
export default defineNuxtPlugin({
    hooks: {
        'page:transition:finish'() {
            ('Page transition finished');
            // Updating page titles
             = 'new title';
        }
    }
});

In this example, we update the page title after the page transition is complete.

3.2 Use in combination with other hooks

It can be used with other page hooks (e.g.page:transition:start) are used in combination to control the different phases of the transition effect:

// plugins/
export default defineNuxtPlugin({
    hooks: {
        'page:transition:start'() {
            ('Page transition starting');
            // Possibly add transition states here
        },
        'page:transition:finish'() {
            ('Page transition finished');
             = 'new title'; // 更new title
        }
    }
});

In this example, we output the log at the beginning and the end of the page transition.

4. Application scenarios

  2. Update Statistics: Record user navigation behavior or load times for analysis.
  3. Dynamic Content Updates: Update UI elements or state after the transition is complete to accommodate new content.

5. Best practices in practical development

  1. Keep it simple.: Perform simple actions in hooks to ensure that performance is not compromised.
  2. Effective utilization of logs: Use logging to record page transitions and monitor user experience and behavior.
  3. Proper handling of exceptions: Catch exceptions inside hooks to improve application robustness.

6. Cautions

  • Performance monitoring: Ensure that actions during page transitions do not significantly increase load times.
  • compatibility: Check the transition effect in different browsers to make sure the hook works properly in all environments.
  • Optimize user experience:: Enhance the application experience by providing good user feedback after the transition is complete.

7. Key points

  • page:transition:finish Hooks are called when the page transition is complete and are suitable for executing subsequent logic.
  • Proper use of this hook can enhance user experience and optimize navigation.
  • Execute only on the client side, be sure to handle exceptions within the hook.
