在 jQuery UI 日期选择器中仅选择特定日期（日期列表来自 AJAX）

在这里，我发送电影 ID 并获取可用天数，我想将其设置到日历中。但它不起作用并且它禁用所有日期。它从 PHP 返回日期字符串。日期字符串正确，但日历不起作用。请帮忙。

日期字符串示例

"28-02-2012","29-02-2012","01-03-2012","02-03-2012","03-03-2012","04-03-2012","05-03-2012","06-03-2012","07-03-2012","08-03-2012","09-03-2012","28-02-2012","29-02-2012","01-03-2012","02-03-2012","03-03-2012","04-03-2012","05-03-2012","06-03-2012","07-03-2012","08-03-2012","09-03-2012"

Code

jQuery.post('index.php', {
  'option': 'com_movie',
  'controller': 'reservation',
  'task': 'datelist',
  'format': 'raw',
  'mid': movieid
}, function(result) {
  var onlydates = result.split(',');
  jQuery("#datepicker").datepicker({
    dateFormat: 'yy-mm-dd',
    showOn: "button",
    buttonImage: "<?php echo IMAGES_LINK.'calendar.png';?>",
    buttonImageOnly: true,
    beforeShowDay: function(date) {
      dmy = date.getDate() + "-" + (date.getMonth() + 1) + "-" + date.getFullYear();
      console.log(dmy + ' : ' + (jQuery.inArray(dmy, onlydates)));
      if (jQuery.inArray(dmy, onlydates) != -1) {
        return [true, "", "Available"];
      } else {
        return [false, "", "unAvailable"];
      }
    }
  });
  return;
});

• 仅初始化一次 datapicker；告诉它从全局数组中获取有效日期
• 使用数组文字初始化全局数组，必要时通过 AJAX 更新它
• 致电.datepicker("refresh")每当禁用/启用日期发生变化时——即当您通过 AJAX 获得新结果时
• 您的代码不会在日期中添加前导零，因此$.inArray不会按预期工作

var datelist = []; // initialize empty array

$("#datepicker").datepicker({
    beforeShowDay: function(d) {
        // normalize the date for searching in array
        var dmy = "";
        dmy += ("00" + d.getDate()).slice(-2) + "-";
        dmy += ("00" + (d.getMonth() + 1)).slice(-2) + "-";
        dmy += d.getFullYear();
        return [$.inArray(dmy, datelist) >= 0 ? true : false, ""];
    }
});

$("#button").click(function() {
    datelist = []; // empty the array
    $.post("/echo/html/", {
        // parameters here
    }, function() {
        var result = "28-02-2012,29-02-2012,01-03-2012,02-03-2012,03-03-2012,04-03-2012,05-03-2012,06-03-2012,07-03-2012,08-03-2012,09-03-2012,28-02-2012,29-02-2012,01-03-2012,02-03-2012,03-03-2012,04-03-2012,05-03-2012,06-03-2012,07-03-2012,08-03-2012,09-03-2012"; // dummy result
        datelist = result.split(","); // populate the array
        $("#datepicker").datepicker("refresh"); // tell datepicker that it needs to draw itself again
    });
