Question

I need a code in sharepoint online, that triggers a script to open a file, where the location of file in local computer. In my opinion, this code like button/image/hyperlink/etc, in the background is Javascript/JQUERY (event click) and this button will be placed in a specific column (in the example below the name of column is "FileLocation") in sharepoint list / sharepoint document library. like screen shoot below.

You can insert JS/Jquery script or change the Dom elements on the field through SPFx Field extension.

Besides, some browsers will specifically block local file access this way for security reasons.
