    for(var count = 0; count <=5; count++){
        usersNumbers[count]=window.prompt("Enter your number "+(count+1)+": " );
    }
    document.lotto.usersNumbers.value = output;

 <p><input type=button value="Enter your numbers" onClick="userNumbers()"></p>
 Your Numbers: 
 <textarea name="usersNumbers" rows=1 cols=20></textarea>
 </td>
 </tr>

Answer 1

你可以试试这个:

<textarea name="usersNumbers" id="textarea" rows=1 cols=20></textarea>

 

function userNumbers() {
    var usersNumbers = new Array(5);
    for (var count = 0; count <= 5; count++) {
        usersNumbers[count] = window.prompt("Enter your number " + (count + 1) + ": ");
    }
    document.getElementById("textarea").value = usersNumbers;

    // if using form
    //document.lotto.usersNumbers.value = usersNumbers;
}
