这是我的 jsp 页面，因为我使用的是日期选择器，但不是从两个日期选择器的范围，我只想使用周。如果我选择了开始日期，然后我必须写下周数，然后我该如何计算结束日期基于该周数和开始日期？我是这个 jquery 的新手，所以任何人都可以帮助我吗？

这是我现在正在使用的 javascript...

function advurldisabled() {
var days= $("#weeks").val();
var thisDate = $("#validBeforeDatepicker").datepicker("getDate");
d = $('#validBeforeDatepicker').datepicker('getDate');
d.setDate(d.getDate()+days); // add int nights to int date
alert(d);
//thisDate.setDate(thisDate.getDate() + days);
alert(thisDate);
}
但 d 变量即将为空
我在我的 java 脚本中以下列方式进行了更改
<script type="text/javascript">
// function to add number of days (accepts number of days to add)
function advurldisabled() {
var days= $("#weeks").val();
var thisDate = $("#validBeforeDatepicker").datepicker("getDate");
alert(thisDate);
thisDate.setDate(thisDate.getDate() + days);
alert(thisDate);
var d = $('#validBeforeDatepicker').datepicker('getDate');
d.setDate(d.getDate()+days); // add int nights to int date
alert(d);
}
// call your function like this
</script>
第一个警报显示以下日期格式
Thu Nov 08 2012 00:00:00 GMT+0530 (India Standard Time)
第二个警报显示以下值，该值不以周为输入，我在周字段中插入了 1 个数字，结果如下
Sun Jan 20 2013 00:00:00 GMT+0530 (India Standard Time)
现在我只是直接添加几周..不应该乘以 7，但只是为了测试，但仍然不是 11 月 9 日，而是给出不同的日期..请指导我在哪里做错了
