jQuery Datepicker - 根据所选选项刷新可选日期 [英] jQuery Datepicker - refresh pickable days based on selected option

问题描述

我有一个选择框，用户可以在其中选择 3 家不同的商店.商店 2 和 3 不应该选择周末，而商店 1 应该只能选择周一至周六.

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.

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.

The following javascript only works on the first pick. If you choose another shop right after, it will stick with the old options.

我试过使用 $( "#datepicker" ).datepicker("refresh");(见 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.

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.

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");
  }
});

HTML:

  <select id="shop" name="shop">
    <option value="0" selected="selected">Choose a shop</option>
    <option value="1">1 (closed sundays)</option>
    <option value="2">2 (closed weekends)</option>
    <option value="3">3 (closed weekends)</option>
  </select>
  <label for="datepicker">Datepicker</label><input type="text" name="date" id="datepicker" value="" readonly="readonly" />

如何使用日期选择器正确刷新/应用设置?

How do I refresh/apply the settings correctly with datepicker?

推荐答案

参见:DEMO

See this: DEMO

  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");
  }

每次更改设置之前，您都需要输入 $("#datepicker").datepicker("destroy");...

You need to put $("#datepicker").datepicker("destroy"); each time before changing settings...
