Plugin: Get the selection in a PDF page

[le zhang]

Hi,

I am also learning how to develop a zotero plugin as the OP of this post where they said that they can get the selection using the following snippet: 

- `readerinstance._iframeWindow?.getSelection()`
- `readerinstance._iframeWindow?.document.getSelection()`
- `window.getSelection()` which listens to the `selectionchange` event.

I am stuck. I get nothing in the Tools > Developer > Run JavaScript after running any line of the above code. 

Could anyone please kindly point me the right direction? 

Thanks

Best,

Lerner

An example:

zotero-plugin-toolkit/docs/zotero-plugin-toolkit.readertool.getselectedtext.md at master · windingwind/zotero-plugin-toolkit (github.com)
