I am taking introductory JavaScript course, and I learned about isNaN function.
I wrote a simple program where JS repeat prompt method unless user type number in the prompt.
I don't know why my code doesn't work as I expected. If you input on the prompt twice, the program automatically escapes while loop.
<script>
var userSalary = prompt("Hi, type a number!");
while(isNaN(userSalary)){
parseFloat(prompt(userSalary+ " is not number..."));
userSalary.reset()
}
alert("Thank you!");
</script>
You aren't setting the value of userSalary in the loop:
var userSalary = prompt("Hi, type a number!");
while(isNaN(userSalary)){
userSalary = parseFloat(prompt(userSalary + " is not number..."));
}
alert("Thank you!");
