JavaScript初學者：做循環重複

Question

我不知道爲什麼這樣做，雖然代碼不能重複問問題...並且在我把這些做的同時......根本沒有功能......

<script type='text/javascript'> 
var done; 
do{ 
var num = prompt("Enter Number", "0") //prompt user to enter the number 
number = parseInt(num); //parse the num to number 
var i; 

document.write('<table border="1" cellspacing="0">'); 
for(i=1;i<=12;i++) 
    { 
    document.write("<tr><td>" + i + " x " + number + " = " + number*i + "</td></tr>"); 
    } 
    document.write("</table>"); 
}while(window.confirm("Do you want to enter another number to show another multiplication table?") 



</script> 

Answer 1

你錯過了在}而paranthesis結束... ...線

<script type='text/javascript'> 
var done; 
do{ 
    var num = prompt("Enter Number", "0") //prompt user to enter the number 
    number = parseInt(num); //parse the num to number 
    var i; 

    document.write('<table border="1" cellspacing="0">'); 
    for(i=1;i<=12;i++) 
    { 
    document.write("<tr><td>" + i + " x " + number + " = " + number*i + "</td></tr>"); 
    } 
    document.write("</table>"); 
}while(window.confirm("Do you want to enter another number to show another multiplication table?")) 

Answer 2

我想你忘記了 '）' 符號，關閉while

jsfiddle

while(
    window.confirm(
     "Do you want to enter another number to show another multiplication table?" 
    ) 
) // <- This one
