not titleBar

When invoking this interface, if the left value (or similar) on iOS is 0, or if Android returns an error {error: 1111, errorMessage: 'not titleBar'}, it is possible that the capsule button in the navigation bar has not completed rendering.

Try to invoke this interface again later to ensure that the capsule button has been fully rendered.

Q&A

How to obtain the position of the favorite button？

Use themy.getMenuButtonBoundingClientRect JSAPI to obtain information related to the favIcon(indicating the the favorite button).

How to obtain the collection status of mini program?

Use the my.isCollected JSAPI to determine whether the mini program is collected.

Why is the capsule position data inaccurate or even negative?

On iOS, the top, left, and similar values may sometimes be 0. This issue can be avoided by calling the function with a short delay.

What is the reason for receiving a 'not titleBar' error when invoking this JSAPI?

This issue might arise if the navigation bar capsule button has not yet fully rendered. Consider invoking this API again after waiting for a short period. For more information, see the Error Codes section.
