【中文标题】如何在 jquery datepicker 中动态禁用特定日期？【英文标题】：how to dynamically disable specific date in jquery datepicker? 【发布时间】：2018-03-16 03:02:53 【问题描述】：我正在尝试动态禁用数据库中已经存在的日期（jquery datepicker）。我已经完成了静态方法，因为我能够实现目标但在动态方法中没有取得成功
<script language="javascript">
$(document).ready(function ()
var getfromdb = @html.Raw(@ViewBag.bookdate);
var result = '\'' + getfromdb.toString().split(',').join('\',\'') + '\'';
var disableddates = [result];
var newdisableddates = ['17/10/2017','18/10/2017','19/10/2017','22/10/2017','23/10/2017','24/10/2017','25/10/2017']; // Static Approach
$("#txtFromdate").datepicker(
minDate: 0,
beforeShowDay: DisableSpecificDates,
dateFormat: 'dd/mm/yy'
);
$("#txtTodate").datepicker(
minDate: 0,
beforeShowDay: DisableSpecificDates,
dateFormat: 'dd/mm/yy'
);
function DisableSpecificDates(date)
var string = jQuery.datepicker.formatDate('dd/mm/yy', date);
return [disableddates.indexOf(string) == -1];
);
这是我的控制器代码：
List<string> getbookdate = new List<string>();
getbookdate = BookDate(id);
ViewBag.bookdate = JsonConvert.SerializeObject(getbookdate.ToList());
public List<string> BookDate(int? id)
DateTime dt = System.DateTime.Now.Date;
var getbookdate = (from x in entity.BookingMasters
join
y in entity.BookingDetails on x.BookingId equals y.BookingId
where x.ProductId == id && y.FromDate > dt && y.ToDate > dt
select new BookingModel ProductId = x.ProductId.Value, FromDate = y.FromDate.Value, ToDate = y.ToDate.Value ).ToList();
List<string> allDates = new List<string>();
foreach (var r in getbookdate)
for (DateTime date = r.FromDate; date <= r.ToDate; date = date.AddDays(1))
allDates.Add(Convert.ToString(date.ToShortDateString()));
return allDates;
【问题讨论】：
【参考方案1】：禁用不适用于日期选择器。试试我的plnkr。
https://embed.plnkr.co/h4RaeIKJVfj9IjyHREqZ/
它在点击时获取日期选择器并解析给定的日期和数据集，如果找到匹配项，它会删除其上的点击事件。并在每个渲染上重复，请参阅我的 plnkr 链接以获取 html。希望对你有帮助

【讨论】：
你查看我的 plnkr 链接了吗？它有效..你能告诉发生了什么【参考方案2】：您最初的想法是正确的方向，但我认为所有字符串转换可能都发生了一些奇怪的事情。我只是通过日期并与日期进行比较，而不是所有的字符串： 我已经写了这个快速测试...
控制器：
//Replace with however you get dates
ViewBag.DatesList = new List<DateTime>()
new DateTime(2018, 01, 01),
new DateTime(2018, 01, 02),
new DateTime(2018, 01, 03)
;
return View();
查看：
<script language="javascript">
$(document).ready(function ()
var disableddates = [];
@foreach (DateTime date in ViewBag.DatesList)
//note JS month is zero-based for no good reason at all...
@:disableddates.push(new Date(@date.Year, @date.Month-1, @date.Day))
$("#txtFromdate").datepicker(
minDate: 0,
beforeShowDay: DisableSpecificDates,
dateFormat: 'dd/mm/yy'
);
$("#txtTodate").datepicker(
minDate: 0,
beforeShowDay: DisableSpecificDates,
dateFormat: 'dd/mm/yy'
);
function DisableSpecificDates(date)
//filter array to find any elements which have the date in.
var filtereddates = disableddates.filter(function (d)
return d.getTime() === date.getTime();
);
//return array with TRUE as the first (only) element if there are NO
//matching dates - so a matching date in the array will tell calling
//code to disable that day.
return [filtereddates.length == 0];
);
</script>
这似乎对我有用。
【讨论】：
忘记添加 - 这也可以解决本地化问题（您的原始代码假定 ToShortDateString() 将始终以您在 JS 中测试的格式返回日期，但情况可能并非总是如此。从MSDN : "ToShortDateString 方法返回的字符串是文化敏感的。它反映了当前文化的 DateTimeFormatInfo 对象定义的模式。"以上是关于如何在 jquery datepicker 中动态禁用特定日期？的主要内容，如果未能解决你的问题，请参考以下文章
