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

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; 
}

尝试：

document.lotto.usersNumbers.value = userNumbers.join(); 

为了给你号的逗号分隔列表。如果需要，您可以传递不同的分隔符到.join。
