How to resolve the issue of Uniapp not rendering the page after changing data.

The reason why the page does not refresh after changing the data in uniapp is usually due to incorrect data binding or the data change not triggering a page update. You can try the following methods to resolve the issue:

1. Ensure correct data binding: use data binding syntax such as {{data}} or :data in the template to bind data to page elements accurately.
2. Manually trigger page update: After the data changes, you can try calling this.$nextTick() or this.$forceUpdate() method to manually trigger the page update.
3. Use watch to monitor data changes: Use the watch property to monitor changes in the data needed to update the page, automatically refreshing the page when the data changes.
4. When updating data in an array or object, it is advisable to use the $set method to notify UniApp of the changes for responsive data.

By following the above methods, you should be able to solve the issue in Uniapp where the page doesn’t re-render after data changes. If you still can’t solve it, please check if the code logic and data binding method are correct.
