你好，这种情况你可以考虑在jsp页面写点js代码
同时为你展示的标签写个id="time"的属性
代码如下：
<script language="javaScript">
var now = new Date(date),hour = nowgetHours() ；
if(hour < 13){
documentgetElementById('time')value='上午'
}else {
documentgetElementById('time')value='下午'
}
</script>
希望能帮到你
" 'customer='zz' and time=#null#' 中" 看起来customer的名字是获取到了，但是日期没有正确获取，显示的是“#null#”，我也好久没写JSP了，建议你先用写死的日期看看，如果可以用，说明就是time没有正确获取，考虑一下类型转换什么的
可以使用格式化标签：
1首先，导入fmt标签<%@ taglib prefix="fmt" uri=">
加个时间不一定要通过下拉列表来做 因为你还需要把年月日组合到一个变量中
直接用控件做到文本框中是个方便的方法 然后通过documentgetElementById("文本框id名")value获取变量值即可
下面是一个做好的例子 可以拿去参考参考
