如何从提示窗口获取响应并将其显示在网页的某个位置？

我现在的代码是：

<html>

<head>

	<center>

		<FORM> 

			<INPUT type="button" value="Click Me." name="button" onClick="alert('I Like Waffles')">

			<INPUT type="button" value="Whats Your Favorite Food" name="button" onClick="prompt('Whats Your Favorite Food?')">

		</FORM>

	</center>

</head>

</html>

我想知道如何从提示中获取响应并将其放在html中。
