jQuery(function ($) {
$.datepicker.regional['zh-CN'] = {
closeText: '关闭',
prevText: '<上月',
nextText: '下月>',
currentText: '今天',
monthNames: ['一月', '二月', '三月', '四月', '五月', '六月',
'七月', '八月', '九月', '十月', '十一月', '十二月'],
monthNamesShort: ['一', '二', '三', '四', '五', '六',
'七', '八', '九', '十', '十一', '十二'],
dayNames: ['星期日', '星期一', '星期二', '星期三', '星期四', '星期五', '星期六'],
dayNamesShort: ['周日', '周一', '周二', '周三', '周四', '周五', '周六'],
dayNamesMin: ['日', '一', '二', '三', '四', '五', '六'],
weekHeader: '周',
dateFormat: 'yy-mm-dd',
firstDay: 1,
isRTL: false,
showMonthAfterYear: true,
yearSuffix: '年'
};
$.datepicker.setDefaults($.datepicker.regional['zh-CN']);
});

$.datepicker._gotoToday = function (id) {
var target = $(id);
var inst = this._getInst(target[0]);
if (this._get(inst, 'gotoCurrent') && inst.currentDay) {
inst.selectedDay = inst.currentDay;
inst.drawMonth = inst.selectedMonth = inst.currentMonth;
inst.drawYear = inst.selectedYear = inst.currentYear;
}
else {
var date = new Date();
inst.selectedDay = date.getDate();
inst.drawMonth = inst.selectedMonth = date.getMonth();
inst.drawYear = inst.selectedYear = date.getFullYear();
this._setDateDatepicker(target, date);
this._selectDate(id, this._getDateDatepicker(target));
}
this._notifyChange(inst);
this._adjustDate(target);
}
