I'm working on a Greasemonkey userscript for a web app that needs configuration steps before I can actually test my userscript's functionality. So every time I reload the page – to refresh my userscript from the updated file –, I have to reconfigure the web app before testing. Needless to say, this gets old very quickly.
Is there a way to reload only the userscript, preferably from the userscript itself? I would want to e.g. bind the reload to a keyboard shortcut.
I thought that this must be a very common need, but I came up empty-handed when trying to find a solution.
Might want to have alook into AJAX for this then, it's a tool that interacts with databases without refreshing the webpage. I.E - dynamic webpages.
Might help, just do a general google browse and see if it applies.
Generally not feasible.
As one of the collaborators remarked on this issue in GreaseMonkey's GitHub repo, almost all scripts mutate the page in ways that makes repeated script execution problematic.
I overlooked this fact in my original question – my script does mutate the page in ways that makes repeated script execution problematic.
If you want to implement script reload, and you find a feasible method to do that:
- make sure you carefully evaluate what effect will it have on the page, and
- implement clean-up code to prepare the page for the repeated execution of your script.
