我是javascript和jquery的新手。我想通过datepicker获取用户选择的日期值,并使用我的javascript中的值。我的datepicker的名字是birthDate。这是日期选择器的html代码:
<guis:datePicker required="true" label="Birthdate"
bean="${accountInfo}" field="birthDate"
value="${accountInfo?.birthDate?:"none"}"
noSelection="${['null':'']}"/>
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';
return false;
}
return true;
}
</script>
datepicker返回的值采用以下格式:
Wed Jun 13 00:00:00 PHT 1990
..而新的日期是:
2012年6月6日星期三17:08:52 GMT + 0800(PHT)
请帮忙!
谢谢!

正如您所说,您以dd/mm/yyyy
格式获得了日期,请尝试使用
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!");
如果你也在使用jQuery,你可以这样做:
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!");
希望这能帮到你!

如果你在#datepicker
id元素中有它,你可以使用val获取值并将其转换为Date,如下所示:
new Date( $('#datepicker').val() )
这会让你回到Wed Jun 20 2012 00:00:00 GMT+0100 (BST)
:)
干杯!
