InvalidAccessError on IE 11

Hi

Using the newest IE 11 (as of today) on Windows 11 pro, I encountered the following wired InvalidAccessError:

Which happens on this line.

The root cause of this is because MS IndexedDB implementation (for whatever reason not clear to me) expects a fix number literal as a second argument and refuses to evaluate any expression like dbVersion || 1 or dbVersion etc. The same line works like a charm using Chrome Version 42.0.2311.135 m on Windows.

My current workaround is:

dbReq = indexedDB.open(dbName, 1);

Which of course is not a real fix to this issue!

Another better - but still odd - workaround is to change the line to

dbReq = indexedDB.open(dbName, parseInt(dbVersion) || 1);

This works for me on IE TP (Edge) on Windows 10, untested on IE 11.

There seems to be something odd about IE's interpretation of the type. typeof dbVersion returns "number" and yet wrapping in parseInt seems to do some magic to really make it a number.

Thanks!

I verified that your fix on IE 11 works as well. Would you mind to provide a PR for this. Maybe with some code comments saying that this would be required on IE etc.?
