So my while loop with isNaN doesn't work when I type in number in the prompt
Here is my code below...
var userSalary = prompt("Please type your salary!")
while(isNaN(userSalary)){
prompt("Please type number!")
}
alert("Good!")
Although I input a number, it won't let me escape from the loop...
You need to reassign userSalary inside of the loop, so the value gets refreshed:
var userSalary = prompt("Please type your salary!")
while(isNaN(userSalary)){
userSalary = prompt("Please type number!")
}
alert("Good!")You could combine the statements, and also try a do..while loop
var userSalary = prompt('Please type your salary!')
while (isNaN(userSalary = prompt('Please type number!'))) {}
alert('Good!')
