datepicker进阶篇

<link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.16/themes/base/jquery-ui.css" type="text/css" media="all">
<label for="from">From</label> <input type="text" id="fDate" name="from"/> <label for="to">to</label> <input type="text" id="toDate" name="to"/>

var dateToday = new Date();
var dates = $("#fDate, #toDate").datepicker({
    defaultDate: "+1w",
    changeMonth: true,
    numberOfMonths: 3,
    minDate: dateToday,
    onSelect: function(selectedDate) {
        var option = this.id == "fDate" ? "minDate" : "maxDate",
            instance = $(this).data("datepicker"),
            date = $.datepicker.parseDate(instance.settings.dateFormat || $.datepicker._defaults.dateFormat, selectedDate, instance.settings);
        dates.not(this).datepicker("option", option, date);
    }
});

执行效果：to的起始日期会随着from选中的日期变化

From to

//如果想要控制toDate的时间范围
var newDate = new Date();
newDate.setDate(newDate.getDate() + day);
$('#toDate').datepickTW("option", "maxDate", newDate);

 目前博客园不能执行js，因此无法看到实时的效果
