Create a specific date range with jQuery datepicker
提问by bigmike7801
I'm trying to use the jQuery date picker to create a start date calendar and an end date calender. I'm using the "date range" example seen here: http://jqueryui.com/demos/datepicker/#date-range
我正在尝试使用 jQuery 日期选择器来创建开始日期日历和结束日期日历。我正在使用此处看到的“日期范围”示例：http: //jqueryui.com/demos/datepicker/#date-range
The start date can not be before today's date and the end date can be 30 days past the selected start date.
开始日期不能早于今天的日期，结束日期可以是所选开始日期之后的 30 天。
For example if I chose a start date of May 17th in the first datepicker, then the end date in the second datepicker can only be selectable for May 18th through June 18th.
例如，如果我在第一个日期选择器中选择了 5 月 17 日的开始日期，那么第二个日期选择器中的结束日期只能选择 5 月 18 日至 6 月 18 日。
Here's my code:
这是我的代码：

instance = $( this ).data( "datepicker" ),
date = $.datepicker.parseDate(
instance.settings.dateFormat ||
$.datepicker._defaults.dateFormat,
selectedDate, instance.settings );
dates.not( this ).datepicker( "option", option, date );
}
});
});
</script>

<input type="text" id="from" name="from"/>
<label for="to">to</label>
<input type="text" id="to" name="to"/>
</div><!-- End demo -->

Any help would be appreciated. Thanks!

There you go : http://jsfiddle.net/c0mm0n/SJhmF/3/
你去吧：http: //jsfiddle.net/c0mm0n/SJhmF/3/
$(function() {
$( "#from, #to" ).datepicker({
defaultDate: "+1w",
changeMonth: true,
numberOfMonths: 3,
onSelect: function( selectedDate ) {
if(this.id == 'from'){
var dateMin = $('#from').datepicker("getDate");
var rMin = new Date(dateMin.getFullYear(), dateMin.getMonth(),dateMin.getDate() + 1); // Min Date = Selected + 1d
var rMax = new Date(dateMin.getFullYear(), dateMin.getMonth(),dateMin.getDate() + 31); // Max Date = Selected + 31d
$('#to').datepicker("option","minDate",rMin);
$('#to').datepicker("option","maxDate",rMax);
}
}
});
});

This should do it:
这应该这样做：
$(function() {
var fromDate = $("#from").datepicker({
defaultDate: "+1w",
changeMonth: true,
numberOfMonths: 2,
minDate: new Date(),
onSelect: function(selectedDate) {
var instance = $(this).data("datepicker");
var date = $.datepicker.parseDate(instance.settings.dateFormat || $.datepicker._defaults.dateFormat, selectedDate, instance.settings);
date.setDate(date.getDate()+30);
toDate.datepicker("option", "minDate", date);
}
});
var toDate = $("#to").datepicker({
defaultDate: "+1w",
changeMonth: true,
numberOfMonths: 2
});
});
Basically this sets the from date's minDate to today. Then when you select a fromDate, it sets the minDate of the toDate to the selected date +30.
基本上这将起始日期的 minDate 设置为今天。然后，当您选择 fromDate 时，它将 toDate 的 minDate 设置为所选日期 +30。
