Duplicated text in QR Code Activity history

I think there is no use of logging the same user in the dropdown menu if he generate his qrcode again.

Here is the ex-

Here what to be expected -

working on this

Have a look in qrtextdropdown id and attach the if statement to check if previous div value is same or not.

• I think before making/working we should ask one of the maintainers.

This wouldn't work. the names are being stored in a global array called history. If I run the condition check at the div change,the array would still be different every time because it would just contain the same name multiple times.
Instead I attached the statement at the beginning of the pushtohistory function so if the name already exists in the array it's not pushed at all

[yog24esh]

Yes but instead of checking the whole array , checking the last pushed element in the array would be useful otherwise it would defeat the purpose of history.
Ex - If a user1 generate qrcode. arr->[user1]
user2 generate qrcode. arr->[user1,user2]
user1 again generate qrcode. arr->[user1,user2,user1]
user1 is already present in array but it should be logged because it shows the history.

[Scar26]

Hm...makes sense,I mean I probably could just let it be logged into history and run the test in the for loop that they are using to append in the div. But it would be a little less efficient since we have to check a higher number of elements every-time. On the other hand, it makes sense that history should contain everything.

@llaske can we have your opinion on this?

Easy access to old generated QR code is more useful than a real history with duplication.

So #317 fixed the issue in my opinion.
A supplemental fix is here: #339
