Question

我正在尝试对两个日期进行比较，一个是从我的数据库中获取的日期，另一个是用户在HTML输入表单上的数字。日期格式为DD / MM / YYYY。我们的用户必须通知字段dPaid_Date上的日期以及它将出现在nPaid_Amount上的结果，它将根据用户支付的日期显示金额...

<form action="PM_CL_Include08.php" name="form" method="POST">

我找到了一种方法：

<form action="PM_CL_Edit02.php" name="form" method="POST" onsubmit="return fValidate(this);">
    <input type="hidden" name="nYear" value="2016">
    <input type="hidden" name="nMonth" value="1">

将它们转换为Date对象，然后进行比较。

http://www.w3schools.com/js/js_date_methods.asp

var testdate1 = Date.parse("11/30/2011");
var testdate2 = Date.parse("12/30/2012");

// Can use relational operators < <= > >= for dates

testdate1 <  testdate2; // true
testdate1 <= testdate2; // true
testdate1 >  testdate2; // false
testdate1 >= testdate2; // false

抱歉，我的约会＆＃39;上课没有补充。无论如何，更新的方法更快。

用javascript比较日期
