jQuery Datepicker - 根据所选选项刷新可选日期

标签: javascript jquery datepicker

我有一个选择框,用户可以选择3个不同的商店。不应该为商店2和3选择周末,对于商店1,你应该只能选择周一至周六。

以下javascript仅适用于第一个选择。如果您之后选择另一家商店,它将坚持使用旧选项。

我尝试使用$( "#datepicker" ).datepicker("refresh");(请参阅how to refresh datepicker?),但没有成功。我开始认为问题出在其他地方。

使用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" />

请参阅: 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,您需要添加$("#datepicker").datepicker("destroy"); ...
