Question:how to display Alert when people asking you by using prompt?

[lala138]

My problem is that when the PROMPT box asking you to input a number, then the program should display/alert the number of times that you just input. I know how to do it by using form but prompt. Please help me. Thanks a lot.

That doesn't make any sense

Yes, I think so too. But this is the homework that my friend asked me today. I took 2 hours to try, but still don get it. So I ask for help here.
Is it really not make sense??

Rather basic:

<script type="text/javascript">
  var number = prompt('Please choose a number','');
  var count = 1;
    if(!isNaN(number)){
      while(count<=number){ 
            alert('You have entered '+number+'\nThis is alert '+count+++' of '+number);
      }
    }       else{ alert('You did not choose a number!') }
</script>

</script>

Wow.... You are excellent man. It works very fine. BTW, can you teach me how to display the number on the main page,(not Alert). Like the prompt ask you : prompt("choose a number!"); such as number 5 . Then if i want to display the "ouch!" 5 times on the main page. How to do that ? Thank you so much !

This sounds like homework, is this homework? If so, post what you have and we can help. Can't just do though.

Edit: oh, already said it's homework, at least it's someone elses though. Better tell you what's going on to make sure you learn .

<script type="text/javascript">
  var number = prompt('Please choose a number',''); //your prompt
  var count = 1; //How many times has it gone
  var str="Ouch!"; //what word we are writing
    if(!isNaN(number)){ //is the input a number? If it is go to the while loop else go to the alert at the end
      document.write('You have entered '+number+'<br />'); //Tell the user what number they chose
      while(count<=number){  //until count greater than the number the user entered. Write ouch and the number of ouches so far.  Increment count each pass. 
            document.write('This is Ouch '+count+++' of '+number+'<br />');
      }
    }       else{ alert('You did not choose a number!') }  //this alert will display if the input is not a number
</script>
