我对 javascript 和 jquery 真的很陌生。我想通过 datepicker 获取用户选择的日期的值，并在我的 javascript 中使用该值。我的日期选择器的名称是birthDate。这是我的日期选择器的 html 代码：
<guis:datePicker required="true" label="Birthdate"

我的 javascript 是：
<script type="text/javascript">
function isOfLegalAge() {
var currDate = new Date();
var birthDate = $("#datepicker").val();
var diff = currDate - birthDate
alert (currDate);
alert(birthDate);
if(diff >= 18){
return true;
}else {
alert("You must be atleast 18 years old to register!");
document.location.href = '/user';

As you have said that you got the date in dd/mm/yyyyformatTry this,
正如你所说，你得到了dd/mm/yyyy格式的日期试试这个，
var myDate = "06/06/2012";
var currentDate = new Date();
var compareDate = currentDate.getDate() + "/" + currentDate.getMonth() + "/" + currentDate.getFullYear();
if (myDate == compareDate)
alert("Both dates are equal!");
else
alert("Dates mismatch!");
In case, if you are using jQuery also, you can do this:
万一，如果您也使用 jQuery，您可以这样做：
var date = '06/06/2012';
var arrDate = date.split("/");
var today = new Date();
useDate = new Date(arrDate[2], arrDate[1] -1, arrDate[0]);
if (useDate == today)
alert("Both dates are equal!");
else
alert("Dates mismatch!");
Hope this helps you!
希望这对你有帮助！

try this
试试这个
<form:input cssStyle="background-image:url('../images/DateCal.png');
background-repeat:no-repeat; background-position: right;"
path="requirementDate" id="datepicker1"
/>
$(document).ready(function() {
var dates= $( "#datepicker1" ).datepicker({
changeMonth: true,
changeYear: true,
yearRange: '2012:2022'
});
});

if you have it in #datepickerid element you can use val to get value and turn it into Date like this:
如果您在#datepickerid 元素中有它，您可以使用 val 获取值并将其转换为 Date ，如下所示：
new Date( $('#datepicker').val() )
this will give you back Wed Jun 20 2012 00:00:00 GMT+0100 (BST):)
这会让你回来Wed Jun 20 2012 00:00:00 GMT+0100 (BST):)
Cheers!
干杯!
