how to remove/convert all non-numbers a user might input into the prompt box for ex: $ , . letters etc?

code so far: // create a rng // collect user input // print a random number 1 >= user's provided number

anything entered into the prompt box that is NOT 0 - 9 breaks the program.

var item = prompt('What would you like to sell?'); var userNumber = parseInt(prompt('How much do you want for the ' + item + ' ?')); var offerPrice = parseInt(Math.ceil(userNumber) * Math.random() + 1); alert('Would you take $' + offerPrice + ' for your ' + item + ' ?');

""... Use the string's .replace method with a regex of \D, which is a shorthand character class that matches all non-digits:

myString = myString.replace(/\D/g,''); ...""

found the above at stack will this work also for the prompt box? Also is this way above what I'm learning? I have never seen .replace or the \D
