这是我的jsp页面，因为我使用日期选择器而不是两个日期选择器的范围我只想使用周。如果我有选择开始日期然后我必须写周数，然后怎么能我根据周数和开始日期计算结束日期？ 我是这个jquery的新人，所以任何人都可以帮助我吗？

这是我现在使用的javascript ...
<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");
d = $('#validBeforeDatepicker').datepicker('getDate');
d.setDate(d.getDate()+days); // add int nights to int date
alert(d);
//thisDate.setDate(thisDate.getDate() + days);
alert(thisDate);
}
但是d变量为空
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>
first allert显示以下日期格式
Thu Nov 08 2012 00:00:00 GMT+0530 (India Standard Time)
显示以下值的第二个警报，其中没有输入周数，并且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了几周......但是只是为了测试，但仅仅是为了测试，但仍然不是在09年11月它给出了不同的日期..请指导我在哪里做错了
答案 0 :(得分：4)
简单。试试这个：
function advurldisabled() {
// Get the week from input
var weeks = $('#weeks').val();
// Get the selected date from datepicker
var thisDate = $('#validBeforeDatepicker').datepicker('getDate');
var d = new Date(thisDate);
// Add weeks to the selected date, multiply with 7 to get days
var weekLater = new Date(d.getFullYear(), d.getMonth(), d.getDate() + weeks * 7);
// Set the new date to the datepicker
$('#datepicker').datepicker('setDate', weekLater);
//alert(weekLater);
}

答案 1 :(得分：1)
Here a little fiddle在某个日期增加了几周。
HTML：
<input type="text" id="weeks"></input>
<br/>
<input type="text" id="from"></input>
<br/>
<p id="to"></p>
<br/>
<div id="calc">CALC!</div>
JavaScript的：
var today = new Date();
$('#from').val(today);
$('#calc').click(function() {
var weeks = $('#weeks').val();
var datefrom = new Date($('#from').val());
var dateto = new Date();
dateto.setDate(datefrom.getDate()+weeks*7);
$('#to').text(dateto);
});
在进行计算之前，请确保您的日期格式正确。
