是否把jsp的变量跟javascript的对象搞混了？
javascript是无法直接取jsp的变量的
在jsp页面中加入<input type=hidden id=aaa value="<%=变量名%>">
(jsp的语法不记得了，好像是这样写的)
然后在javascript中alert(document.forms[0].aaa.value)

求大家帮我找一下其中的年，月，日三个变量名！<html>

除非你可以在改变什么之后刷新页面,让jsp代码重新执行才行的哦
对象-object
变量-变量的数值
函数-有返回值返回返回值
没有返回一段代码
我一般是把javascript的代码用alert来显示
而jsp或是其他的变量用什么东西.write就行了呀
