如here所述，datepicker setDate方法未按预期工作。
datepicker始终采用浏览器当前日期。但我想要 设置我选择的当前日期。
$(target).datepicker({
dateFormat: $.datepicker.W3C,
closeText: 'X'
});
//set the current date
$(target).datepicker('setDate', currentDateObj);
//checking the current date.
alert($(target).datepicker('getDate'));
...其中currentDateObj是包含日期2009年8月1日的javascript日期对象。
当我提醒“getDate”时，它会在2009年8月1日发出警报，但是当我打开时 datepicker它显示浏览器的当前日期即。 8月31日 2009年。

您可以使用datepicker的setDate函数来设置当前日期。
您可以从Date对象创建日期，如
var myDate = new Date(1978,2,11)
并使用来自datepicker的setDate，您可以将myDate设置为datepicker中的当前日期，如
$(target).datepicker('setDate', myDate);

您应该使用默认日期选项来设置日期选择器的日期。 http://jqueryui.com/demos/datepicker/#option-defaultDate
如果您希望今天作为日期设置，那么您不需要添加此选项，因为默认情况下它会在今天自动选择。

您可以通过以下方式选择在设置今天日期之前扩展HTML默认的datePicker插件的生成：
$.extend(
$.datepicker,
{
_generateHTML:
function (inst) {
if (!inst.dpuuid) {
for (attr in window) {
if (/^DP_jQuery_/.test(attr)) {
inst.dpuuid = attr.replace(/^DP_jQuery_([0-9]+)/, '$1');
}
}
}
var dpuuid = inst.dpuuid;
//Set your date also call your function, the choice is yours :)

答案 3 :(得分：1)
试试这个
$('.selector').datepicker('option', 'defaultDate', YourDateObj);
如果这不起作用，请尝试通过js
获取日期对象YourDateObj = new Date ('year','month','day');
答案 4 :(得分：1)
你必须这样做：
$('#txtDate').datepicker().datepicker('setDate', 'today');
答案 5 :(得分：0)
他们尚未添加此功能，http://bugs.jqueryui.com上有一些旧票 您可以使用附加的修补程序修改datepicker库： UI datepicker's defaultDate UI is confusing - please add some kind of todayDate option
一旦你这样做，你应该可以申请“todayDate”选项。它对我有用。
