JS prompt - calculator (калькулятор) 2

Question

Please help me Refine the calculator. When you enter letters, you need to ask them to enter again until you enter a number.

Прошу помощи в доработке калькулятора. Нужно чтобы при вводе букв предлагать еще раз ввести, пока не введете цифру.

Answer 2

Why not use <input type="number"> for the width, length and height? once the button is clicked you validate the three values and proceed when all is OK.

Running a loop asking for input over and over again can be annoying.

(Edit)
Please use the tags properly, you can put code link in Description and use the tags to specify a language name instead 👍

Thanks, I'll try it now.
