再问JSP日期控件验证 - -！

这是例子：

我的JSP代码：

<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>



<html>

  <head>

    <title>My JSP '0902.jsp' starting page</title>

  </head>

  <script language="javascript" type="text/javascript" src="My97DatePicker/WdatePicker.js"> </script> 

  <body>

    form:<input id="d4311" class="Wdate" type="text" onFocus="WdatePicker({maxDate:'#F{$dp.$D(\'d4312\')||\'2020-10-01\'}'})"/> To:

	<input id="d4312" class="Wdate" type="text" onFocus="WdatePicker({minDate:'#F{$dp.$D(\'d4311\')}',maxDate:'2020-10-01'})"/>

  </body>

</html>

是按照例子来做的为什么没用效果呢？？

我不是计算差多少天只是限制第2个日期不小于第1个日期而已

<script>

var firstDate = new Date("2008-01-02".replace(/-/g,"/"));

var secondDate = new Date("2008-01-01".replace(/-/g,"/"));

if(firstDate > secondDate){

	alert("第二个日期必须大于第一个");

}

</script>

判断2个日期相差多少天注意格式yyyy-mm-dd

function daysBetween(DateOne,DateTwo)
{
var OneMonth = DateOne.substring(5,DateOne.lastIndexOf ('-'));
var OneDay = DateOne.substring(DateOne.length,DateOne.lastIndexOf ('-')+1);
var OneYear = DateOne.substring(0,DateOne.indexOf ('-'));
var TwoMonth = DateTwo.substring(5,DateTwo.lastIndexOf ('-'));

return Math.abs(cha);
}

JS已经正确导入了

<input name="submit" id="submit" type="submit" value="first" onClick="new WdatePicker(this,false)">

<input name="submit2" id="submit2" type="submit" value="second" onClick="new WdatePicker(this,false)">

能正常调用！
