The simple solution would be to *comment out (or temporarily delete) the command before running local tests, then restore it before uploading. That said, it is possible to run it locally. As @Szaal said, that process is detailed in the topic for the save plugin, but here’s what I remember of it:
- First, you download two additional
.jsfiles, and place them in the same folder as the other.jsfiles. - Then you edit one of the
index.htmlfiles, so that the new.jsfiles will be called when the original.jsfiles are called. - Then you use the
*sm_initcommand.
It’s probably more trouble than it’s worth to implement it locally, but the option exists.
Edit: This should be the post with the relevant downloads and instructions, if you decide to implement it locally.
