Why can a command in Safari’s Javascript (JS) console not call a previously defined function

consolejavascriptsafari

I have the latest MacOS and Safari on a 2012 Macbook Pro.

https://stackoverflow.com/questions/50513038/how-to-automate-download-of-generated-pdfs/50515826#50515826
provides me with a function and a loop to call multiple times.

If I paste the function definition into the JS console, then the loop command, nothing happens.

If I change the function call to "console.log" and put that in, it prints the correct parameters.

If I redefine the function to call console.log and type in the call again, that works. If I then paste the original loop, nothing happens.

Conclusion: Safari JS console doesn't allow injected JS to call a user-defined function.

Is that a bug, or is there a security setting that I need to change?

I can't reproduce the problem you're having. I've tried with the following JavaScript executed in the console.

I split the screenshots for each step from your question but the actual commands were executed in the console on one page without reloading.

All seems to work correctly as it should! Perhaps the question could do with some screenshots of what you're trying.
