  <script type="text/javascript">
      function myFunction() {
          var x = parseInt(document.f1.n1.value);
          var y = parseInt(document.f1.n2.value);
          if(x>=y) {
              document.write("Invalid");
          }
          while (x<y)
          {
              document.write(x)
              x=x+1;
          }
      }
  </script>
  <form name=f1 onsubmit="return false">
   First no. <input type="text" name="n1">
   Second no. <input type="text" name="n2">
   Answer: <input type="text" name="ans" disabled>
   <input type="submit" onClick="myFunction()">

Answer 1

你可以这样做：

给答案输入一个id：

<input id="answerTextBox" type="text" name="ans" disabled>

while 循环后填充答案文本框：

while (x>y)
{
document.getElementById("answerTextBox").value += ("" + x);
x=x+1;
}

这会将 x 和 y 放入您的答案文本框中。

Answer 2

The number inserted in the textbox is the number of exponent it will generate. The sample is 3. 3X3X3 is 27. <br>
<script type="text/javascript">
function myFunction() {
var x = document.f1.n1.value;
while(x<27)
{
x=x*3;
}
document.write(x)
}
</script>
<form name="f1" onsubmit="return false">
First no. <input type="text"name="n1" value=3 disabled>
<input type="submit" onClick="myFunction()">
