box for input string/number from user. (like Prompt instead of alert)

box for input string/number from user. (like Prompt instead of alert)

I need to get a string from user during my custom script
Is there any way to do a command like prompt-method?
username = prompt('Please enter your name');

Script works in List view as Button for each record.
I know about "alert" - but in this case I need _input_ and return a value entered by the user.
So, please, advise what the best
