Question

我试图通过jsp在mysql数据库中插入日期。使用引导日期选择器接受日期。 mysql中shipping_date和delivery_date的数据类型是date（也尝试使用datetime）。它给了我无法预料的日期错误。请帮我解决这个问题。在此先感谢..`

这里的整个代码是：

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

    <%@page import="java.text.SimpleDateFormat,java.text.DateFormat,java.text.ParseException" %>

我通过使用JavaScript验证而不是引导日期选择器解决了这个问题。以下是它的代码..

<script type="text/javascript">
$(function(){
    var dtToday = new Date();

    var month = dtToday.getMonth() + 1;
    var day = dtToday.getDate();
    var year = dtToday.getFullYear();
    if(month < 10)
        month = '0' + month.toString();
    if(day < 10)
        day = '0' + day.toString();

    var maxDate = year + '-' + month + '-' + day;
    $('#shipping_date').attr('min', maxDate);
});

$("input[name='shipping_date']").change(function() {
      $("input[name='delivery_date']").attr('min',$(this).val());
    });

</script>

另外，我将shipping_date和delivery_date的输入类型更改为

<input type="date" name="shipping_date" id="shipping_date" required>

使用jsp在mysql数据库中插入bootstrap datepicker日期
