prompt() method not working in workspace

Assuming you don't have a syntax error my guess is that you closed the prompt window and selected the checkbox that prevents other popups opening from that website. Try closing and re-opening the tab. I am not sure if that works on all browsers, but if I have diagnosed this correctly then it should work on chrome.

Hello all, here is the latest code that I tried, and it has done the same thing on other codes.

var randomNumber = getRandomNumber(10);
var guess;
var guessCount = 0;
var correctGuess = false;

function getRandomNumber( upper ) {
  var num = Math.floor(Math.random() * upper) + 1; 
  return num;
}

while( guessCount < 10) {
  guess = prompt('I am thinking of a number between 1 and 10. What is it?');
  guessCount += 1;
  if (parseInt(guess) === randomNumber) {
    correctGuess = true;
    break;
  }  
} if ( correctGuess )

document.write('<h1>You guessed the number!</h1>');
document.write('It took you ' + guessCount + ' tries to guess the number ' + randomNumber);
else{
  document.write( '<h1> Sorry. You did not guess the number. </h1>');
}

I will check my pop up settings and see if that fixes the problem. Thanks!

So I looked at you code and found a syntax error. You had forgotten the curly braces for the if statement near the end. Be sure to look and the developers console in your browser when code does not work as expected. It often gives you a message when there are errors that can help you find a solution.

Also here is a working version of your code:

var randomNumber = getRandomNumber(10); 
var guess; var guessCount = 0; 
var correctGuess = false;

function getRandomNumber( upper ) { 
    var num = Math.floor(Math.random() * upper) + 1; return num; 
}

while( guessCount < 10) { 
    guess = prompt('I am thinking of a number between 1 and 10. What is it?'); 
    guessCount += 1; 
    if (parseInt(guess) === randomNumber) { 
        correctGuess = true; 
        break; 
    }
} 

// This was the if statement that was missing the curly braces
if ( correctGuess ) {
    document.write('You guessed the number!'); 
    document.write('It took you ' + guessCount + ' tries to guess the number ' + randomNumber);
} else { 
    document.write( ' Sorry. You did not guess the number. '); 
}
