# Deprecation: #64598 - Deprecate PagePositionMap::JSimgFunc {#deprecation-64598}

See [forge#64598](https://forge.typo3.org/issues/64598)

## Description {#description}

The following function has been marked as deprecated:

-   `TYPO3CMSBackendTreeViewPagePositionMap::JSimgFunc`

This method was used only in class PagePositionMap. The implemented "onmouseover" / "onmouseout"
behaviour to switch between two images was dropped entirely for now. If this is needed, it should
done a different way.

## Impact {#impact}

Using this function in a backend module will throw a deprecation message.

## Affected Installations {#affected-installations}

Every Extension that uses the deprecated function.

## Migration {#migration}

Write own JavaScript functions for your extension to handle onmouseover and onmouseout events to
switch between two images.
