Today, when developing the Vue3 background management page, I created several menu bars and wrote the page. After writing, the test found that these pages can only display the page effect after the first click after the page is refreshed. How to click and switch later No, it's a blank page.
After a long investigation, I found that even if Vue3 supports Vue page, it is not necessary to wrap it with a single node, but we try to use a single node to wrap it, so as to avoid other strange problems (the page does not load).
If it is not my reason, you can also check whether it is these problems, or it may cause the page to not load and display blank.
-
Routing configuration issues: Please make sure the routing configuration is correct, each menu item corresponds to the correct component or page, and the routing path is set correctly.
-
Component loading problem: Check whether the corresponding component is imported correctly and the path is correct. Also, verify that the component renders as expected.
-
Permission control issues: If there is permission control, ensure that the current user has permission to access the switched page. Whether to display the corresponding menu items can be determined by verifying user permissions.
-
Data loading problem: If the page needs to obtain data display from the backend, confirm whether the data is successfully loaded and used correctly in the page. Check whether the network request is normal and ensure that the data is passed to the component correctly.
-
Error handling: Please check the browser console for any error messages that can help you find the exact problem. Check logs and error messages for possible problems.
-
Other problems: There are some other possible problems, such as internal logic errors of components, style problems, etc. Please check your code and related configuration further.
