jQuery Datepicker - refresh pickable days based on selected option
提问by estrar
I have a select box where the user can pick 3 different shops. It shouldn't be possible to pick weekends for shop 2 and 3, and for shop 1 you should only be able to pick Mon - Sat.
我有一个选择框，用户可以在其中选择 3 个不同的商店。应该不可能为商店 2 和 3 选择周末，而对于商店 1，您应该只能选择周一至周六。
The following javascript only works on the first pick. If you choose another shop right after, it will stick with the old options.
以下 javascript 仅适用于第一个选择。如果您之后立即选择另一家商店，它将坚持使用旧选项。
I've tried using $( "#datepicker" ).datepicker("refresh");(see how to refresh datepicker?) but without any success. I'm starting to think that the problem lies elsewhere.
我试过使用$( "#datepicker" ).datepicker("refresh");（查看如何刷新日期选择器？）但没有任何成功。我开始认为问题出在其他地方。
Javascript:
Javascript：
$(function() {
var setting, currentShop = 0;
/* Select box */
$('select#shop').change(function() {
(currentShop = $(this).val() == 1) ? loadDatePicker(setting = 'noSunday') : loadDatePicker(setting = 'noWeekends');
});
/* Datepicker */
function noSunday(date){
var day = date.getDay();
return [(day > 0), ''];
}
function loadDatePicker(setting) {
if(setting == 'noWeekends') {
$( "#datepicker" ).datepicker({ beforeShowDay: $.datepicker.noWeekends, minDate: +2, maxDate: "+1M" });
}
if(setting == 'noSunday') {
$( "#datepicker" ).datepicker({ beforeShowDay: noSunday, minDate: +2, maxDate: "+1M" });
}
$( "#datepicker" ).datepicker("refresh");
}
});

<option value="3">3 (closed weekends)</option>

See this: DEMO
看这个：演示
function loadDatePicker(setting) {
$("#datepicker").datepicker("destroy");
if(setting == 'noWeekends') {
$( "#datepicker" ).datepicker({ beforeShowDay: $.datepicker.noWeekends, minDate: +2, maxDate: "+1M" });
}
else if(setting == 'noSunday') {
$( "#datepicker" ).datepicker({ beforeShowDay: noSunday, minDate: +2, maxDate: "+1M" });
}
$( "#datepicker" ).datepicker("refresh");
}
You need to put $("#datepicker").datepicker("destroy");each time before changing settings...
您需要$("#datepicker").datepicker("destroy");在更改设置之前每次放置...
